Plumbing that fits how Gainesville actually lives

Gainesville sits where I-66 meets US-29 (Lee Highway) in western Prince William County — a census-designated place of 17,287 people as of the 2020 Census. It grew fast from a railroad crossroads into a mix of 1980s and 90s subdivisions, golf-course communities, and new townhouse rows near Virginia Gateway. That mix is exactly why plumbing here can't be one-size-fits-all.

The ground sets the rules. This is Piedmont country — dense clay soil that swells after heavy rain and shrinks in dry spells, and it pushes on foundations, floor drains, and sewer lines with every swing. The area averages about 43 inches of rain a year, per climate data for ZIP 20155, so basements and crawl spaces get tested often. For many homes here, a working sump system is the difference between a dry rec room and a very bad weekend.

Then comes winter. January lows average in the mid-20s, and every few years a deeper cold snap settles over Northern Virginia. A lot of the townhouses and ranches run on slabs or low crawl spaces, with pipes tucked into exterior walls — so uninsulated hose bibbs and laundry lines are the first casualties. The pattern repeats every January: the freeze hits, the thaw follows, and the leaks start.

The water itself is its own story. Most homes are served by Prince William Water — the utility renamed from the Prince William County Service Authority in 2024 — which blends Potomac River water treated at Fairfax Water's Corbalis plant with Lake Manassas water treated by the City of Manassas. It runs moderately hard in stretches of the western county, which is rough on water heaters and fixtures over time. Out toward the Bull Run Mountain edge, in Evergreen, some homes draw from community wells, and rural pockets still rely on private wells in Piedmont bedrock — each with its own quirks around pressure, sediment, and treatment.

The housing stock tells the rest. Wellington and the older pockets along the Lee Highway corridor date to the 1980s and 90s, an era when some builders used polybutylene supply piping. Heritage Hunt, the 55-plus golf community, was built starting in the late 1990s, and many of its homes have finished basements that lean on ejector pumps. Newer builds in Dominion Valley, Piedmont, and around Virginia Gateway are younger but sit on the same restless clay. We size every recommendation — repair, replace, or leave alone — to the house in front of us, not a script.

Bathtub Repair & Installation service — Plumbing Pros

Bathtub Repair & Installation Near Me

Starting at: Call for pricing

Replacing a bathtub has no undo button — once the tub is set and the surround closes, the drain, overflow, and leveling are buried for years. Plumbing Pros treats every tub install as a one-shot job: set dead level, connect the waste-and-overflow while everything is reachable, and test under a full load before the surround goes on. We also repair existing tubs — leaking overflow gaskets, stoppers that will not hold, slow drains, and failed caulk.

  • Dead-level setting on a mortar bed or ledger — no flex, rock, or creak.
  • Waste-and-overflow installed before the tub drops, with every joint reachable.
  • Full-tub water test under load before the surround closes.

  • Every penetration sealed with caulk or expanding foam
Dishwasher Installation & Hookup service — Plumbing Pros

Dishwasher Installation & Hookup Near Me

We level and anchor the machine, then run a full test cycle while watching every connection for drips.

  • New quarter-turn shutoff valve on the hot supply line.
  • Braided stainless supply line checked for seepage under load.
  • Drain routed through an air gap or secured high loop per code.
Drain Cleaning service — Plumbing Pros

Drain Cleaning Near Me

Starting at: Call for pricing

Slow sinks, gurgling tubs, and recurring clogs all trace back to buildup inside the line — grease, hair, soap scum, and lint that a bottle of chemicals only makes worse. Plumbing Pros clears kitchen, bathroom, laundry, and floor drains with pro cable machines matched to the pipe, flushing debris downstream and testing every fixture at full flow before leaving.

  • Cable machines sized to every pipe, from hand augers to full sectional cable.
  • Cutter heads matched to the clog — bulb for soft blockages, blade for roots.
  • Cleanouts used whenever they exist, keeping the mess out of living spaces.
Emergency Plumbing Repair service — Plumbing Pros

The stocked truck handles burst supply lines, failed water heater connections, and backed-up drains in a single visit — containing the damage first, then repairing to code and testing before leaving.

  • Live dispatcher answers every call around the clock with clear shutoff instructions.
  • Trucks stocked with copper, PEX, and PVC fittings for same-visit repairs.
  • Containment comes first — stop the flow, protect floors, keep the family safe.
Faucet Installation service — Plumbing Pros

Faucet Installation Near Me

Starting at: Call for pricing

A new faucet should be the easiest upgrade in the house, yet most installation headaches come from compatibility — hole patterns, deck thickness, and valve families that do not all match. Plumbing Pros does the compatibility work first: a licensed plumber checks hole spacing, identifies the valve type waiting under the sink, and confirms the finish and spout reach suit your basin. Then we bed the base in silicone or putty, connect new braided supply lines, and test every handle position, so the faucet turns smoothly, shuts off completely, and stays dry underneath.

  • Measure hole spacing, deck thickness, and spout reach before you buy.
  • Valve family identified — compression, cartridge, ball, and ceramic-disc trim must match.
  • Base bedded in silicone or plumber's putty with a clean wiped edge.
Faucet Repair service — Plumbing Pros

Faucet Repair Near Me

Starting at: Call for pricing

Drip, drip, drip — that steady sound is water you pay for and never use, usually escaping past a worn washer, O-ring, or cartridge. Plumbing Pros finds the failed part instead of replacing the whole fixture, then rebuilds your faucet with exact-match components. The drip ends in a single visit.

  • Drip-source diagnosis: spout, base, or handle.
  • Cartridge replacement with proper pullers, never pliers.
  • Washer, seat, and O-ring rebuilds for compression faucets.
Frozen Pipe Thawing & Repair service — Plumbing Pros

Frozen Pipe Thawing & Repair Near Me

Starting at: Call for pricing

A faucet that gives a trickle or nothing on the coldest morning means a section of pipe has turned to ice. Plumbing Pros thaws frozen pipes with safe, controlled heat — never an open flame — working from the open faucet back so pressure can escape. We then inspect the full run for splits and repair any damage on the spot.

  • Safe thawing with controlled electric heat — never an open flame.
  • Frozen-section locating by touch and temperature readings.
  • Thawing from the open faucet back so meltwater and pressure escape.
Garbage Disposal Installation service — Plumbing Pros

Garbage Disposal Installation Near Me

Starting at: Call for pricing

Every job includes safe wiring on a switched circuit, fresh sealant at the flange and mounting ring, a proper dishwasher drain hookup, and a full leak test with water running. You also get straight guidance on what the unit handles well, so scraps and rinse water flow away without the clogs and odors that call for a plumber.

  • Unit sizing matched to household size and cooking habits
  • Safe electrical wiring on a switched circuit, done to code
  • Dishwasher drain hookup with knockout plug removed and sealed
Garbage Disposal Repair service — Plumbing Pros

Garbage Disposal Repair Near Me

Starting at: Call for pricing

Flip the switch on a troubled disposal and the sound tells the story: a hum with no grinding means a jammed flywheel, silence means a tripped reset or lost power, a rattle means something hard is inside. Plumbing Pros diagnoses disposals by sound, which is why most of our disposal calls end in repair rather than replacement. We also leave you with the habits that keep units alive — cold water during grinding and a clear list of what never belongs inside.

  • Sound-first diagnosis — hum, silence, and rattle each point to a different failure.
  • Flywheels released with the hex wrench from below — gently worked, never hammered.
  • Lodged objects removed with tongs and pliers; hands never go inside.
Gas Line Installation & Repair service — Plumbing Pros

Gas Line Installation & Repair Near Me

Starting at: Call for pricing

Every gas line joint must be sized, sealed, and tested to code — there is no room for guesswork. Our licensed plumbers install and repair residential gas lines in black iron, corrugated stainless tubing, or copper, pressure-testing every run with a manometer before activation. If you smell gas, leave the area and call for help from outside the home.

  • Electronic leak detection plus bubble solution at every joint.
  • Manometer pressure testing held to confirm a tight system.
  • Black iron pipe cut and threaded on-site for rigid runs.
Hydro Jetting service — Plumbing Pros

Hydro Jetting Near Me

Starting at: Call for pricing

A cable punches a hole through a clog; hydro jetting cleans the entire pipe wall — grease, scale, soap, and root hairs flushed out of the system. Plumbing Pros scopes the line first to confirm it can take the pressure, then jets it clean and verifies the result on camera.

  • Backward-facing jets scour the full pipe circumference, stripping grease and scale.
  • Rearward thrust pulls the hose through the line, letting the operator dwell on buildup.
  • Root intrusions shredded to pulp and flushed out of the system.
Ice Maker Water Line Installation service — Plumbing Pros

Ice Maker Water Line Installation Near Me

Starting at: Call for pricing

  • Dedicated refrigerator shutoff reachable without moving the fridge.
  • Clean routing away from sharp edges, heat sources, and foot traffic.

Kitchen Plumbing Remodel Near Me

Starting at: Call for pricing

A kitchen plumbing remodel from Plumbing Pros rebuilds supply, drain, vent, and gas piping around your new layout, with every rough-in measured to your cabinet drawings.

  • Sink, dishwasher, and refrigerator rough-ins moved to match new cabinet and appliance layouts.
  • Gas line extensions, relocations, and safe capping for range and cooktop moves, pressure-tested.
  • Pot filler stub-outs and ice maker connections placed to exact finished-design locations.
Laundry Room Plumbing service — Plumbing Pros

Laundry Room Plumbing Near Me

Starting at: Call for pricing

Plumbing Pros designs laundry plumbing around how washers actually behave: standpipes at the right height and diameter, drains sized for full pump-outs, and hammer arrestors that quiet valve shock. Hot and cold lines get reachable quarter-turn shutoffs, and every connection is tested under a full wash cycle before we leave.

  • Standpipes set to your washer's specified height and diameter, trapped and vented.
  • Drain piping sized for modern high-efficiency discharge rates.
  • Recessed washer boxes with built-in hammer arrestors.
Leak Detection service — Plumbing Pros

Leak Detection Near Me

Starting at: Call for pricing

Water rarely surfaces where it escapes, which is why leak detection finds the source before anyone cuts drywall or breaks concrete. Our plumber narrows the search zone by zone, then uses acoustic listening gear, thermal imaging, and moisture meters to pinpoint the break behind walls, floors, or slabs. The leak gets marked and the findings written down, so the repair becomes one small, certain job.

  • Meter flow test with everything off confirms the leak and gauges its size.
  • Zone-by-zone isolation of irrigation, heater, and fixtures narrows the search first.
  • Acoustic listening gear hears pressurized leaks inside walls, floors, and slabs.
Main Water Line Repair service — Plumbing Pros

Main Water Line Repair Near Me

Starting at: Call for pricing

A climbing water bill or a meter that turns with every tap closed usually means a hidden leak on the main water line between the meter and the house. Main water line repair targets that single failed section: we confirm the leak, pinpoint the break with acoustic equipment, open one careful excavation, and splice in new pipe with proper couplings. The section is pressure-tested before backfill, proving the fix while the pipe is still visible.

  • Meter flow test with the house valve closed proves the leak is on your side.
  • Acoustic listening equipment and soil probing narrow the break to one small area.
  • One targeted excavation exposes only the failed section, leaving the rest undisturbed.
Main Water Line Replacement service — Plumbing Pros

Main Water Line Replacement Near Me

Starting at: Call for pricing

When every fixture runs weak, water carries a rust tint, or the service line has already been patched more than once, the pipe itself is finished. Main water line replacement renews the entire run from meter to house in a single project, with new copper or approved polyethylene pipe sized for the home and pressure-tested before service resumes. The old line is capped and abandoned, leaving steady pressure and clear water you never have to think about.

  • Pressure readings at meter and inside the house document what the old line loses.
  • Pipe material matched to local code and soil conditions, copper or approved polyethylene.
  • New line sized by fixture count and run length to hold pressure under full use.
Outdoor Faucet & Hose Bibb Services service — Plumbing Pros

Outdoor Faucet & Hose Bibb Services Near Me

Starting at: Call for pricing

Plumbing Pros repairs, replaces, and winterizes outdoor faucets and hose bibbs so they deliver strong flow in summer and survive the cold months. From worn washers to frost-proof sillcock installation and vacuum breaker protection, we handle every part of the fixture. A small valve deserves the same care as any plumbing inside your home.

  • Hose bibb leak repair: washers, seats, stems, and packing rebuilt.
  • Frost-proof sillcock installation with the valve seat inside the warm wall.
  • Vacuum breakers that keep hose water out of your drinking supply.
Pipe Insulation Services service — Plumbing Pros

Pipe Insulation Services Near Me

Starting at: Call for pricing

Plumbing Pros insulates exposed supply lines so pipes hold their warmth through winter and cold-water runs stay dry in summer. A licensed plumber sleeves straight runs in foam, wraps fittings in fiberglass with a vapor jacket, and adds thermostat-controlled heat tape where the cold bites hardest. The result is hot water that arrives sooner, a quieter system, and pipes far less likely to turn icy and split.

  • Foam sleeves sized to each pipe, sealed at the seams
  • Fiberglass wrap with vapor jacket for elbows, tees, and valves
  • Thermostat-controlled heat tape warms only when the air drops
Pipe Leak Repair service — Plumbing Pros

Pipe Leak Repair Near Me

Starting at: Call for pricing

Leaking supply lines soak drywall, warp cabinets, and feed mold long before you see the damage. Plumbing Pros cuts out the failed section and rebuilds it to match your system — soldered copper, press fittings, or PEX — then pressure-tests every joint. Call (877) 401-2673 and we will stop it at the source.

  • Clean, square cuts with professional pipe cutters
  • Soldered copper joints matching existing copper systems
  • Press fittings for tight spaces where torches are unsafe
Reverse Osmosis Drinking Water Systems service — Plumbing Pros

Reverse Osmosis Drinking Water Systems Near Me

Starting at: Call for pricing

A reverse osmosis drinking water system is a compact, multi-stage unit beneath the kitchen sink built for one job: exceptional drinking and cooking water. Tap water passes sediment and carbon pre-filters, then a semipermeable membrane that rejects dissolved solids, with the improvement verified by a TDS meter reading before and after.

  • Four-stage treatment: sediment, carbon block, membrane, polishing filter.
  • TDS meter readings before and after installation prove the improvement.
  • Pressurized storage tank keeps purified water ready at its faucet.
Sewage Ejector Pump Services service — Plumbing Pros

Sewage Ejector Pump Services Near Me

Starting at: Call for pricing

Any bathroom, laundry room, or wet bar below the main sewer line needs a lift — Plumbing Pros installs, replaces, and services sewage ejector pump systems that move wastewater up to the sewer lateral. The heart is a sealed basin with a gasketed lid, sized to your fixtures, with proper venting, a check valve, a shutoff valve, and a high-water alarm on a dedicated circuit.

  • Correct pump selection between effluent and grinder models
  • Proper venting tied into the home's vent system
Sewer Camera Inspection service — Plumbing Pros

Sewer Camera Inspection Near Me

Starting at: Call for pricing

Digging up a yard on a hunch is expensive — a sewer camera inspection ends the guessing. Plumbing Pros feeds a self-leveling camera through a cleanout while you watch live, marking every root mass, belly, offset, or crack on the surface with a locator, and hands you the recording.

  • Self-leveling camera head keeps the picture upright for accurate readings.
  • Sonde transmitter locates every defect from above ground with depth marked.
  • Watch the inspection live and ask questions as the camera travels.
Sewer Line Repair service — Plumbing Pros

Sewer Line Repair Near Me

Starting at: Call for pricing

Clay joints shift, cast iron corrodes, and settled pipe creates bellies — every sewer line fails in slow motion until backups arrive faster each time. Plumbing Pros cameras the line first, then fixes only what is broken: spot repairs, trenchless pipe bursting, or cured-in-place lining, with the finished line verified on camera.

  • Camera inspection and surface locating before any quote, so the plan matches the defect.
  • Spot repairs replace only the failed section through a single excavation.
  • Pipe bursting pulls a new continuous line through the old pipe's path.
Sewer Line Replacement service — Plumbing Pros

Sewer Line Replacement Near Me

Starting at: Call for pricing

When a sewer line keeps backing up despite repeated cleanings, the pipe itself is usually the problem: sagging bellies, root-packed joints, or flattened sections that no snaking can fix. Sewer line replacement ends that cycle by removing the old line from the house to the city connection and installing new PVC or HDPE with correct slope, sealed joints, and fresh cleanouts. Most homes return to normal drainage within days, with a final camera video documenting the new line.

  • Camera inspection with locating sonde maps the failing line from house to street.
  • Written trench plan shows the dig path, depth, pipe material, and opening points.
  • Old clay, cast iron, or broken pipe is fully removed and replaced with new PVC.
Shower Repair & Installation service — Plumbing Pros

Shower Repair & Installation Near Me

Starting at: Call for pricing

When the shower turns scalding with every flush, the culprit is usually a worn pressure-balancing spool or tired cartridge — not the showerhead. Plumbing Pros fixes shower trouble at the valve: we identify the valve by manufacturer pattern, replace the cartridge or diverter, and restore steady temperature and full flow. For remodels and new installs, we set the valve at the correct depth, pressure-test the rough-in, and flood-test the pan before walls close.

  • Cartridge diagnosis by symptom — we match drips, stiffness, and swings to the failed part.
  • Cartridges replaced with the correct puller and fresh lubricant, never forced.
  • Pressure-balancing and thermostatic upgrades that hold temperature under demand.
Sink Repair & Installation service — Plumbing Pros

Sink Repair & Installation Near Me

Starting at: Call for pricing

Sink trouble rarely announces itself at the basin — it shows up as a musty cabinet, a swollen floor, or a drip that only appears when the dishwasher drains. Plumbing Pros traces every sink problem to its source, whether that means reseating a strainer basket, rebuilding a drain assembly, or installing a new sink matched to your countertop. Every job ends with a full-basin release test, so the cabinet stays dry and the drain runs quiet.

  • Trace leaks to the source — strainer, trap, tailpiece, or supply lines — before quoting.
  • Strainer baskets reseated in fresh putty with the locknut torqued evenly.
  • P-traps replaced with correct alignment and slope, cleanout left accessible.
Slab Leak Repair service — Plumbing Pros

Slab Leak Repair Near Me

Starting at: Call for pricing

A slab leak is a pressurized water line leaking beneath your home's concrete foundation. Plumbing Pros pinpoints these hidden leaks with acoustic listening equipment and thermal cameras, then repairs them by overhead reroute or direct slab access. Call (877) 401-2673 if your floors feel warm or your water bill looks wrong.

  • Acoustic listening equipment that locates leaks under concrete
  • Thermal cameras that reveal hot-line leaks through the slab
  • Moisture meters mapping how far dampness has spread
Smart Water Leak Detectors service — Plumbing Pros

Smart Water Leak Detectors Near Me

Starting at: Call for pricing

Smart leak detectors watch the spots where water damage begins — under sinks, behind the washer, and around the water heater — and alert your phone the moment water appears. Plumbing Pros installs wireless sensors plus an automatic main-line shutoff that stops the flow even when nobody is home. It turns a potential flood into a notification and a quick response.

  • Whole-home leak-risk survey to place sensors where leaks begin.
  • Wireless moisture sensors for sinks, toilets, laundry, and water heater.
  • Automatic main-line shutoff valve that closes when any sensor trips.
Sump Pump Discharge Freeze Protection service — Plumbing Pros

Sump Pump Discharge Freeze Protection Near Me

Starting at: Call for pricing

Plumbing Pros keeps your sump pump discharge line open through the cold, because a pipe that ices shut sends groundwater right back into the basement. A licensed plumber re-pitches the line to drain fully between cycles, insulates exposed sections, and sets the outlet well clear of the foundation with an overflow escape route. The pump, float, and battery backup are tested too, so the whole system stands ready for winter storms.

  • Pump, float switch, and check valve inspected and tested
  • Discharge line re-pitched to drain fully between pump cycles
  • Exposed pipe sections wrapped in foam insulation sleeves
Sump Pump Installation service — Plumbing Pros

Sump Pump Installation Near Me

Starting at: Call for pricing

When heavy rain or a high water table pushes water toward your foundation, Plumbing Pros designs and installs complete sump pump systems — pit, basin, pump, check valve, and discharge line — for basements and crawlspaces. We dig the pit to the right depth and width for your soil, size the pump to real inflow so it cycles calmly instead of burning out, and route discharge well away from the house. Every system gets a dedicated electrical connection, an airtight basin lid, a full wet test, and battery backup options for storm-season peace of mind.

  • Pit excavation sized to your soil and water inflow
  • Pump capacity matched to real inflow, not a guess
  • Quality check valve on the discharge line stops backflow
Sump Pump Repair & Maintenance service — Plumbing Pros

Sump Pump Repair & Maintenance Near Me

Starting at: Call for pricing

Plumbing Pros repairs failing sump pumps and keeps healthy ones that way with thorough maintenance visits, working through the usual suspects — float switches, check valves, intake screens, impellers, and electrical issues — and testing the whole system under load. Each visit covers cleaning, float testing through full cycles, valve and discharge checks, and alarm testing, with plain notes on what we found. If your pump runs constantly, short-cycles, or makes grinding sounds, those early warnings are worth acting on before the next big rain.

  • Float switch diagnosis and replacement, tethered or vertical
  • Check valve testing and replacement when it sticks or leaks
  • Water alarm installation and testing for rising pit levels
Tank Water Heater Installation service — Plumbing Pros

Tank Water Heater Installation Near Me

Starting at: Call for pricing

A new tank water heater should match your household's demand, fuel supply, and venting — not just fit the space. Plumbing Pros installs gas and electric tanks to code, with proper venting, expansion control, and haul-away of the old unit. Call (877) 401-2673 to talk through sizing and options.

  • Sizing matched to your household's peak demand
  • Gas and electric options compared honestly
  • Code-compliant venting with proper draft and clearances
Tankless Water Heater Installation service — Plumbing Pros

Tankless Water Heater Installation Near Me

Starting at: Call for pricing

  • Load calculation matched to your household's simultaneous hot-water demand.
  • Gas line sizing and upsizing for the burner's higher fuel flow.
  • Sealed venting routed through wall or roof to code.
Toilet Installation & Replacement service — Plumbing Pros

Toilet Installation & Replacement Near Me

Starting at: Call for pricing

A cracked tank, a hopelessly rocking base, or a remodel can all call for a new toilet — and the difference between decades of solid service and a leak within a year comes down to the flange and the setting. Plumbing Pros measures your rough-in, repairs the flange, sets the new unit on a fresh seal, and tests every connection.

  • Rough-in measurement before you buy the new unit.
  • Selection guidance on bowl shape, height, and trapway design.
  • Closet flange inspection, repair rings, and height correction.
Toilet Repair service — Plumbing Pros

Toilet Repair Near Me

Starting at: Call for pricing

The toilet that flushes itself at night has a leaking flapper; the one that runs forever may need a fill valve or a water-level adjustment. Plumbing Pros diagnoses the actual cause — running, rocking, weak flush, or clogs — and repairs it with quality parts, usually in a single visit.

  • Symptom-based diagnosis before any parts come off.
  • Fill valve replacement with correct water-level setting.
  • Flappers matched to your tank's flush volume.
Trenchless Sewer Repair service — Plumbing Pros

Trenchless Sewer Repair Near Me

Starting at: Call for pricing

Trenchless sewer repair rebuilds a failing line from the inside through small access points, leaving driveways, patios, and landscaping untouched. A camera inspection first confirms the line qualifies, then we install either a cured-in-place resin liner or new HDPE pulled through by pipe bursting. The result is a smooth, jointless new pipe, and most households have full service back within a day or two.

  • Camera inspection with measured footage confirms the line qualifies for trenchless methods.
  • Cured-in-place liners form a seamless new pipe inside the old one.
  • Pipe bursting replaces lines too damaged for lining with new HDPE.
Water Heater Maintenance & Flushing service — Plumbing Pros

Water Heater Maintenance & Flushing Near Me

Starting at: Call for pricing

That popping and rumbling from the utility closet is sediment insulating your burner from the water. Plumbing Pros drains and flushes the tank, inspects the anode rod, and tests the relief valve and burner — scheduled care that keeps heaters quiet, efficient, and long-lived.

  • Full tank draining with sediment agitation and clean refill.
  • Anode rod inspection and replacement before the tank corrodes.
  • Temperature-and-pressure relief valve testing for reliable safety.
Water Heater Repair service — Plumbing Pros

Lukewarm showers, rumbling tanks, and pilots that will not stay lit are usually repairable. Plumbing Pros diagnoses the actual fault — elements, thermostats, gas valves, anode rods — and repairs what is worth saving. Call (877) 401-2673 when the hot water misbehaves.

  • Electrical testing of elements and thermostats
  • Gas valve, thermocouple, and pilot assembly inspection
  • Anode rod inspection gauging remaining tank life
Water Pressure Regulator Services service — Plumbing Pros

Water Pressure Regulator Services Near Me

Starting at: Call for pricing

High water pressure shows up as banging pipes, running toilets, and weeping relief valves — and a pressure regulator on the main line is the fix. We test your pressure with a gauge, then adjust or replace the valve so every fixture gets steady, fixture-friendly pressure.

  • Static and flowing pressure tests with calibrated gauges.
  • Regulator adjustment when the existing valve is still healthy.
  • Full PRV replacement with brass-body valves and strainer screens.
Water Softener Installation & Service service — Plumbing Pros

Water Softener Installation & Service Near Me

Plumbing Pros tests your water, sizes a softener to your actual hardness and household use, and installs the complete system — resin tank, brine tank, bypass valve, and a tidy drain for regeneration.

What Gainesville's homes keep breaking

Sump systems losing the fight with Piedmont clay

Clay holds water tight against your foundation instead of letting it drain away, so after a hard rain the water table around your house can rise fast. In neighborhoods like Wellington and Heritage Hunt, where finished basements are the norm, a tired pump or a missing battery backup turns a storm into a flooded rec room. We test pumps under load, size replacements for the house and the soil, add battery backup where outages are common, and make sure the discharge line runs clear — and won't freeze shut in January.

Hard water quietly killing water heaters

The blended water serving western Prince William County runs moderately hard in many spots, and hardness settles as sediment at the bottom of every tank. That sediment layer makes the burner or elements work harder, shortens the tank's life, and eventually shows up as rumbling noises, lukewarm showers, or a leak from the base. We flush and inspect heaters, replace anode rods before the tank pays the price, and when it's time for a new unit we size it for the household and the water — including tankless options where they make sense.

January freezes splitting hose bibbs and crawl-space pipes

With January lows averaging in the mid-20s, an uninsulated hose bibb or a water line run through a cold crawl space is living on borrowed time. The pipe rarely bursts while it's frozen — it splits, then floods the wall or crawl space when it thaws. Townhouse rows and ranches on slabs are the most exposed. We replace burst bibbs with freeze-resistant models, insulate and reroute vulnerable lines, and winterize outdoor kitchens and irrigation tie-ins before the first hard freeze.

Sewer laterals cracking where the soil moves

Your sewer lateral runs from the house to the county main, and in Gainesville it runs through clay that swells and shrinks with the seasons. That movement shifts pipe joints, and roots hunt down every offset and hairline crack — especially on lots with mature trees. The first signs are slow drains, gurgling toilets, or a backup after heavy rain. We camera the line so you can see the break yourself, then recommend the smallest fix that lasts: a spot repair, or a trenchless liner when the line qualifies.

Polybutylene supply lines in 1980s and early-90s homes

Some homes built in the 80s and early 90s — including parts of Wellington and older pockets along the Lee Highway corridor — still carry their original gray polybutylene supply piping. The pipe itself is less of a problem than the fittings, which can fail without warning and flood a wall cavity or attic. If your home is from that era, a repipe to modern PEX or copper removes the risk in one job. We confirm what you have first, then map the repipe so it happens in days, not weeks.

Basement ejector pumps backing up after storms

A lot of finished basements here — Heritage Hunt homes especially — sit below the sewer main, so bathrooms and laundry depend on an ejector or grinder pump to lift waste uphill. When a float switch sticks or the pump dies during a storm outage, the basement fixtures are the first to back up. We service and replace ejector pumps, test floats and alarms, and add battery backup so the system keeps working when the power doesn't.

How your Gainesville service call goes

1

Tell us what's happening

Call (877) 401-2673 and describe the symptom in your own words — the gurgle, the puddle, the cold shower. We'll ask a few pointed questions to figure out whether it's urgent, what to shut off, and what to expect. If it's a true emergency, we say so plainly and move fast.

2

We look before we quote

The tech inspects in person — camera down the drain, meter on the line, eyes on the actual failure. You see what we see: footage, readings, and a straight explanation of what's wrong and what caused it. No guessing from the driveway, no quote built on a phone description.

3

The plan, in writing

You get your options written down in plain language: what each one fixes, what it doesn't, and which one we'd pick for this house. You choose the path and approve it before a single tool comes out. Nothing gets added mid-job without your say-so.

4

Tidy work, tested as we go

Drop cloths down, work area contained, and every joint pressure-tested or camera-verified before we move on. We flush new lines, check every fixture the repair touches, and confirm the system holds under real conditions — not just at a glance.

5

You sign off, we clean up

We walk the finished work with you, show you what changed, and leave the space cleaner than we found it. You'll get simple maintenance pointers for the season ahead — and if anything feels off afterward, you call the same number and talk to the same crew.

Client Experience

What to Expect Working With Us

"Our basement bathroom started backing up during a storm, and the tech found the ejector pump's float switch had given out. He replaced the pump, added a backup, and showed me how to test the alarm myself. The basement has stayed dry through every storm since."

- Homeowner in Heritage Hunt

"A hose bibb split during the January freeze and soaked the garage wall before we noticed. They had it swapped for a freeze-resistant model the same day, insulated the line in the crawl space, and walked me through shutting the outside water off for winter. No drama, just done right."

- Townhouse owner in Wellington

"Our water heater was rumbling and the showers kept going lukewarm. The tech showed me the sediment coming out on the flush and explained why the tank was done. The new unit went in cleanly, the area was spotless, and the hot water has been steady ever since."

Frequently Asked Questions

Most homes are served by Prince William Water — renamed from the Prince William County Service Authority in 2024. In the western part of the county, including Gainesville, it delivers a blend of two treated sources: Potomac River water from Fairfax Water's Corbalis treatment plant, and Lake Manassas water treated by the City of Manassas. Homes near the Bull Run Mountain edge, in Evergreen, may instead be on community wells, and some rural pockets use private wells.
It can be. Water in the western county runs moderately hard in many areas, and over the years that hardness settles as sediment in water heaters and leaves scale on fixtures. The practical move is a yearly heater flush and an anode rod check — and if you're burning through heaters or fighting constant scale, a softener sized to your actual water and household is worth discussing.
Possibly, yes. Some Evergreen-area homes are served by community wells rather than the county system, and that well water is treated to prevent pipe corrosion — a different profile from the blended surface water most of Gainesville gets. Well households should pay extra attention to pressure tanks, sediment filters, and periodic water testing, since changes show up in your fixtures before anywhere else.
For most significant work, yes — water heater replacements, repipes, sewer line repairs, and gas line work all typically require a county permit and inspection. Smaller repairs like swapping a faucet or clearing a drain don't. When a job needs a permit, we handle the application and coordinate the inspection so you don't have to learn the county's process.
The honest answer is that it comes down to scope and access: how much pipe is involved, what it's made of, how hard it is to reach, whether walls or concrete have to be opened, whether permits and inspections are required, and whether it's scheduled work or a middle-of-the-night emergency. That's why we inspect in person and put options in writing — call (877) 401-2673 and we'll give you a real quote for your specific situation.
January lows here average in the mid-20s, so this matters every winter. Disconnect hoses before the first freeze, make sure hose bibbs are the freeze-resistant type, insulate exposed lines in crawl spaces and garages, and know where your main shutoff is before you need it. If you travel in winter, a proper winterization is cheap insurance — and if a pipe does split, shut the main off first, then call.
The lateral from your house to the county sewer main is yours — the county maintains the main itself, and wastewater from the western county is treated by the Upper Occoquan Service Authority. A camera inspection tells us exactly where the problem sits: if the break or root intrusion is in your lateral, we repair it; if it's in the main, that's the utility's call.
It's worth a look. Some 80s and early-90s builds in this area still have polybutylene supply piping, whose fittings can fail without warning — and older galvanized or cast-iron sections may be corroding from the inside by now. A camera and a supply-line inspection tell you what's actually in your walls, and a repipe is straightforward to plan before something fails on its own schedule.
We cover Gainesville across 20155 and 20156, including Heritage Hunt, Wellington, Dominion Valley, Piedmont, Bridlewood, Virginia Oaks, and the surrounding corridors — plus nearby Haymarket, Bristow, and Manassas.
