New Hampshire plumbing is not generic plumbing — deep bedrock wells with mineral-heavy water, most housing predating 1978, and winter that treats exposed pipe as a stress test. Plumbing Pros works in Manchester, Nashua, Concord, Dover, Rochester, Portsmouth, and Keene with methods shaped by those three facts. Call (877) 401-2673 when your home needs a plumber who already knows what is behind the walls.

Plumbing Built for New Hampshire, Not Anywhere

New Hampshire draws roughly half its household water from private wells — the state counts about 250,000 of them, per the Department of Environmental Services. That divides the state’s plumbing into two worlds: city homes on published, regularly tested municipal supplies, and well homes where the owner is responsible for everything from pump pressure to water treatment. A plumber here has to be fluent in both — municipal codes and city mains on one call, bedrock well pressure tanks and sediment on the next. Plumbing Pros plans every job around which side of that line your home sits on.

The U.S. Geological Survey describes the state’s fractured-bedrock water as soft to moderately hard, with higher iron and manganese than shallow supplies, and hardness that climbs in bedrock aquifers. In a house, that chemistry shows up as rust-colored stains on fixtures, gray laundry that never looks clean, grit collecting in aerators, and mineral buildup shortening the life of water heaters and dishwashers. It is not a health crisis at the tap — it is a maintenance tax on every appliance the water touches. The fix is equipment matched to your actual water: a test first, then a softener, iron filter, or sediment filter sized to what came back.

The housing stock is the other half of the equation. More than half of New Hampshire homes were built before 1978, and nearly one in five went up in 1939 or earlier, according to a statewide healthy-housing fact sheet. That means galvanized steel supply lines narrowing with rust from the inside, cast-iron drains with seventy years of scale, and shutoff valves that have not been touched since the house was wired for electricity. We see originals still in service in farmhouses, Colonials, and mill-era rentals from Manchester to the Seacoast. Replacing them takes planning — not a wrench and a hope.

Then there is winter. American Red Cross guidance puts pipe vulnerability at around 20°F held for six hours or more, and New Hampshire holds those conditions for weeks at a stretch. Fieldstone foundations with gaps you could put a hand through, crawl spaces that were never insulated, hose bibs left connected through October — those are the places pipes ice over and split. The damage usually shows up after the thaw, when a split line opens and water runs for hours. We winterize plumbing the way the state demands: insulation where it counts, real shutoffs on exterior lines, and honest advice about which fixtures need draining before the first hard cold snap.

A Plumber Shaped by the Granite State

Local water, older homes, real winters

Somewhere in your home there is a pipe older than everyone living there. In New Hampshire that is not unusual — it is the job. Plumbing Pros handles the plumbing that comes with Granite State homes: fixture layouts from the 1920s that were never meant for modern use, supply lines routed through places nobody would put a pipe today, and winters that punish every exposed run in the building. Our technicians can read a pressure tank gauge, spot a galvanized supply line by feel, and tell you in plain language what actually needs doing. Before any wrench turns, you will know the scope of the work and why it matters — no inflated stories, no mystery talk. That straightforward way of working is what a long-standing local team looks like, and it is why customers across our seven cities keep our number close.

• Two-system fluency: municipal mains and private wells handled with equal confidence, from city sewer to pressure tank.
• Water-first diagnosis: fixtures, heaters, and pipes evaluated against your actual supply chemistry before we recommend anything.
• Older-home craft: galvanized and cast-iron work done with planning, so repairs do not turn into demolition.
• Pressure-and-flow thinking: pumps, tanks, and lines sized to how your household actually uses water.
• Upfront written options: what needs doing now, what can wait, and what each choice involves — in plain words.
• Clean exits: drop cloths, wiped fixtures, and the work area left better than we found it.

Why New Hampshire Homeowners Call Us First

Seven cities, one way of working

• Show up ready: Our trucks carry the parts New Hampshire jobs actually need — well pump switches, no-hub couplings for cast iron, and insulation for exposed runs.
• Plain-language diagnosis: We explain what is wrong, why it happened, and what your options are, then let you decide. No jargon, no pressure.
• Respect for old houses: We work around plaster walls, tight basements, and original woodwork instead of tearing through them.
• Straightforward scheduling: Real arrival windows, a message when the technician is on the way, and no four-hour mystery window where you wait by the door.
• Honest timelines: If a part has to come in, we say so and give you a real arrival date instead of a vague promise.
• Licensed, insured, permitted: We pull permits where the town requires them and install to code — with paperwork you can keep.
• We answer after the job: If something we touched is not right, call (877) 401-2673 and we come back to make it right.

Plumbing Problems We Fix Across New Hampshire

Iron, manganese, and hard-water staining from bedrock wells

Iron treatment in a New Hampshire well home usually means an oxidation filter that converts dissolved iron into particles a filter can catch — paired with a softener when hardness rides along, and a sediment pre-filter to protect the pump and fixtures downstream. We install treatment on a bypass loop so you are never without water during service, size tanks to your household’s actual use, and set a maintenance schedule you can keep. The wrong unit wastes money; the right one ends the staining for good.

Burst and split pipes during bitter cold snaps

When a line ices over and splits, the damage usually hides until the thaw — a wet ceiling, a hissing wall, a meter spinning with no tap open. Our repair begins with finding the break, not guessing: we isolate the run, open the smallest access that works, and replace the failed section with pipe and fittings chosen for the spot. Then we walk the rest of that run — one split line in a cold-exposed stretch means its neighbors are tired too.

Galvanized supply lines and cast-iron drains aging out

Replacement begins with mapping: we test pressure at multiple fixtures, inspect accessible runs, and identify which sections are actually restricting flow — not every old pipe is a problem pipe. Then we stage the work, worst runs first, usually beginning at the main and moving outward. Modern PEX or copper goes in with minimal opening of finished walls, new shutoffs at logical points, and old galvanized hauled out the day it comes down.

Well pump and pressure-tank trouble

About half the state’s households run on private wells, and the pump and pressure tank are the heart of that system. A waterlogged tank makes the pump short-cycle — kicking on and off constantly — which burns out motors and sends pressure swinging at the tap. Sediment wears pump components; a failing pressure switch leaves you with no water at all. We diagnose the full chain: switch, tank bladder, pump draw, and well yield, then repair or replace only what has actually failed. A right-sized tank and a healthy pump keep the whole house steady.

Sump pump failure during spring thaw

New Hampshire’s spring melt sends a season of water through the ground at once, and basement sump pumps do the heavy lifting. A pump with a stuck float, a worn impeller, or a dead backup battery fails exactly when the water table peaks. We install and service primary and battery-backup pumps, test floats and check valves, and make sure discharge lines run clear of the foundation. A dry basement in April is decided by work done in October, so we check systems before the melt, not during it.

Drain and sewer trouble beyond the municipal line

Outside the cities, homes sit on septic systems or long private laterals, and the household drains still have to get there. Older clay and Orangeburg laterals crack, shift, and invite roots; grease and wipes turn a slow line into a backup. We clear blockages, camera-inspect lines to see exactly what is wrong, and repair or replace failed sections. When the trouble is on the septic-tank side rather than the house side, we say so plainly — and point you to the right specialist instead of selling you work you do not need.

Where We Work in New Hampshire

From the Merrimack Valley to the Seacoast and out to the Connecticut River, Plumbing Pros covers seven New Hampshire cities and the towns around them. Manchester anchors the south with mill-era housing and dense neighborhoods. Nashua brings a mix of Colonials and newer subdivisions near the Massachusetts line. Concord sits at the center with older downtown blocks and well-fed outskirts. Dover and Rochester carry Strafford County’s older mill housing and newer growth alike. Portsmouth adds Seacoast Colonials, tight crawl spaces, and homes where winter arrives first off the water. Keene reaches west into the Monadnock region, where private wells and septic systems are the norm, not the exception. Whether you are on a municipal main in a triple-decker or a drilled well off a dirt road, the technician who shows up knows your setup. Covered ZIPs include 03031, 03060, 03101, and 03102, with 218 covered ZIPs statewide — every visit gets a real arrival window and a technician who treats your home like a home. Don’t see your ZIP code? Call (877) 401-2673 and we’ll confirm coverage, for every corner of the Granite State we serve.

Frequently Asked Questions

How much does plumbing work cost in New Hampshire?

There is no single price — it depends on the scope of the job, the materials involved, how easy the pipes are to reach, the condition of what is already there, whether permits are required, and whether it is an emergency or a scheduled visit. A water heater swap in a wide-open basement prices out very differently from a drain replacement under a finished floor. The honest way to quote is a written scope after someone has seen the work. Call (877) 401-2673 and we will put that scope together.

Is hard water a problem across New Hampshire?

Not usually as scale — New Hampshire water is mostly soft to moderately hard. What it does to homes shows up differently: rust-colored stains, gray laundry, metallic taste, and grit in aerators, driven by iron and manganese that ride along in many bedrock supplies. That is why a treatment plan here begins with a water test, not a hardness number off a chart. Tell us your town and your symptoms and we will tell you what the test should check.

How do I keep my pipes from icing over in winter?

Keep the heat on if you leave for more than a day — a few degrees of warmth costs far less than a split pipe. On the coldest nights, open cabinet doors under sinks on exterior walls and let the most exposed faucet drip so water keeps moving. And know where your main shutoff is before January: a valve you have never touched may not turn when you need it, and testing it in the fall takes two minutes.

My home has a private well — what plumbing work is different?

The pipes and fixtures work the same — what changes is everything before them. Well homes need a pressure tank and pump in good shape, equipment matched to the water’s actual chemistry, and a plan for sediment and power outages. We service the full system: pump troubleshooting, pressure-tank replacement, filtration and softening, and the household plumbing on the other side of it.

What are the signs my old galvanized pipes need replacing?

Low pressure at one fixture that cleaning does not fix, discolored water after the tap sits unused, and visible corrosion or seepage at threaded joints. Inside, galvanized pipe narrows with rust scale — when pressure drops house-wide and the home predates the 1970s, the supply lines are the usual suspect. We can inspect and scope a replacement in stages so you are not paying for everything at once.

Why did my water pressure drop all of a sudden?

Check the easy things first: a clogged aerator, a partially closed shutoff, or a pressure-reducing valve that has drifted. If it is house-wide and nothing obvious changed, the likely causes split by system — a waterlogged pressure tank or tired pump on a well, a failing regulator or narrowing galvanized lines on a city main. We trace it fixture by fixture until we find the restriction, then fix that spot instead of repiping the house.

What should I do if I find a burst pipe?

Shut off the main valve first — know where it is before winter so you are not hunting in the dark. Open the lowest faucet to drain pressure, then call (877) 401-2673. Do not use a torch or heat gun on a pipe you cannot see fully; thawing the wrong way can split it worse or ignite nearby wood. We repair the failed section and make sure the fix will hold when the temperature drops again.
