Plumbing in New London has a personality: old colonials, river fog, and winters that test every pipe in the house. When something starts leaking, backing up, or running cold, Plumbing Pros shows up ready to figure it out. Call (877) 401-2673 and tell us what you're seeing.

Plumbing for a river-and-harbor town

New London sits where the Thames River opens into Long Island Sound, and the plumbing here carries the marks of both. The housing stock runs old: turn-of-the-century colonials and three-story Victorians line the streets from downtown to Riverside Park, and many of them have been split into two- and three-family homes over the decades. That means stacked bathrooms, shared supply risers, and drain lines that were never designed for the number of people using them now. When we open a wall in one of these houses, we are usually looking at a century of additions layered on top of each other.

The city's water system is going through a visible transition. With federal infrastructure funding, New London has been working through roughly 500 lead service lines across its distribution system, replacing the old lead pipe that runs from the water main to older homes. If your house dates to the early 1900s and the service line has never been touched, it is worth finding out what material it is. A lead or galvanized service line does not just affect water quality; it corrodes from the inside, chokes flow, and eventually splits. We can tell you what you are looking at and what your options are.

Then there is winter. New London gets the damp, penetrating cold that comes off the Sound, and it finds every uninsulated run of pipe in the house: hose bibbs, lines along exterior walls, crawlspace plumbing, anything in an unheated garage or basement. A pipe does not need arctic air to freeze here. It needs one long cold night and a draft. We spend every winter thawing frozen lines and repairing the burst fittings that follow, and we would rather help you get ahead of it in the fall.

Salt air is the slower problem. Outdoor faucets, exposed copper, and any metal hardware near the waterfront corrode faster here than inland, and basement humidity runs high in homes close to the river. Sump pumps, dehumidifiers, and proper grading are not luxuries in the lower-lying streets; they are how you keep a basement dry through nor'easters and spring thaws. We set these systems up and keep them running.

So what does Plumbing Pros actually do for a New London homeowner? We diagnose first and explain in plain language. You get the cause, your options, and an honest recommendation before any work starts, and the work area is left clean when we finish. No jargon, no pressure, no mystery charges. If something is not urgent, we will tell you that too. Call (877) 401-2673 and describe what you are seeing; we will take it from there.

Plumbers who know old riverfront houses

Diagnosis first, straight talk, tidy work

Most plumbing calls in this town start with something the house hid for eighty years: a lead service line, a capped gas lamp pipe, a drain tied into another drain that nobody documented. Figuring out old houses without tearing them apart is a skill, and it is the one Plumbing Pros is built around. We use cameras, acoustic listening, and pressure testing to see inside walls and underground lines before we cut anything. Our people work on this city's exact mix of plumbing every week: colonials and capes, converted multi-families, waterfront condos, and the rental stock near downtown. We keep our trucks stocked for the calls that come up again and again here, which means most repairs finish in one visit. And we write down what we found, so the next person who works on your house is not starting from zero.

• Diagnosis before demolition: instruments and cameras first, saws only when necessary
• Plain-language explanations: what failed, why it failed, and what it will take to fix it
• Respect for old construction: we match repair methods to century-old houses, not new-build shortcuts
• One-visit readiness: trucks stocked for the failures this town's housing stock produces most
• Clean work areas: drop cloths, boot covers, and a broom at the end of every job
• Honest triage: if it can wait, we say so; if it cannot, we say that too

The plumbing troubles New London brings us most

Lead and galvanized service lines reaching their limit

Many of the city's oldest streets still have service lines installed when lead or galvanized steel was standard. These lines corrode from the inside out, which means your pressure drops gradually over years and the water can pick up discoloration or sediment. With the city replacing roughly 500 lead lines in its system, homeowners are discovering what sits on their side of the curb stop. If your home predates the 1950s and the line has never been replaced, a camera inspection and a material check are worth doing before it fails on its own schedule.

Frozen hose bibbs and burst lines after cold snaps

The Sound keeps autumns mild and winters damp, which lulls people into skipping winterization. Then a January cold snap drops into the teens overnight and the hose bibb you forgot to shut off splits inside the wall. We see this every winter, along with frozen supply lines in crawlspaces and unheated basements. The fix is preventive: shut off and drain exterior lines before the first freeze, insulate exposed runs, and know where your main shutoff is. If a line does freeze, we thaw it and check the fittings before pressure comes back.

Drain backups in converted multi-family houses

When a single-family colonial becomes a three-unit rental, the drain system absorbs two more kitchens and two more bathrooms than it was built for. Grease, wipes, and years of buildup narrow old cast-iron or clay lines until a downstairs unit starts backing up every few months. Snaking clears the immediate clog, but a camera inspection shows whether the line itself is the problem: bellies, offsets, root intrusion, or pipe that has simply aged out. We clear what is clearable and tell you honestly when the line needs work.

Sump pumps and damp basements near the river

Low-lying streets and a high water table mean many New London basements take on water during nor'easters and spring thaws. A sump pump that has not run in months can seize exactly when you need it, and a discharge line that freezes in winter can back the whole system up. We install, repair, and test sump pumps, and we check the full chain: the pit, the float switch, the discharge route, and a backup power option. A dry basement is a system, not a single appliance.

Salt-air corrosion on outdoor plumbing

Homes within a few blocks of the water see outdoor faucets, hose connections, and exposed metal fittings corrode far faster than the same parts inland. Brass and copper hold up better than cheap zinc hardware, and frost-proof sillcocks stand up to both the salt and the freeze. When we replace outdoor plumbing near the shore, we spec materials that are built for it. It costs a little more attention up front and saves a mid-winter surprise later.

Water heaters failing in cramped old basements

A water heater tucked into a hundred-year-old basement has a hard life: damp air, tight access, sediment from older supply lines, and a flue that may have been modified three owners ago. Sediment shortens tank life and raises energy use, and a failing anode rod lets the tank rust from the inside. We flush and service tanks, replace anodes, and when replacement is the right call, we size the new unit to the household and the space. Tankless is an option in some homes, but the gas line and venting have to be right, and we will tell you if they are not.

How a service visit with us unfolds

1. Tell us what you are seeing: Call (877) 401-2673 and describe the problem in your own words: where the water is, what it sounds like, when it started. The more specific you are, the faster we can zero in. We will ask a few questions and give you a realistic sense of what to expect.
2. We look with instruments, not guesses: On site, we trace the problem with cameras, acoustic listening, moisture meters, and pressure tests. In old houses this matters more than anywhere: we want to find the actual failure, not the nearest convenient pipe to replace. You see what we see.
3. You get options in plain language: We explain what failed and why, then lay out your options with straight talk about what each one solves and what drives the cost. You choose the path. We do not start work until you understand it and agree to it.
4. We do the work neatly: Drop cloths go down, the work area gets contained, and old materials are hauled out. In finished spaces and century-old plaster, we cut only what we must and keep the opening as small as the job allows. Most common repairs are completed in a single visit.
5. We confirm it is fixed and write it down: Before we leave, we test everything under real conditions: run the fixtures, check the pressure, look for drips. Then you get a written summary of what was found and what was done, so you have a record for the next owner, the next contractor, or your own files.

Testimonials

Our hose bibb burst inside the wall during that cold snap in January and water was coming through the basement ceiling. They found the split fast, opened up the smallest section of wall possible, and had it repaired and patched back the same visit. They even showed me how to shut the line off properly for next winter.

The first-floor unit kept backing up every couple of months and two other companies just kept snaking it. These folks ran a camera and found a bellied section of the old drain line. They explained exactly what was happening and gave me real options instead of another temporary fix.

When I bought the house I had no idea what kind of service line I had. They checked it, told me straight that it was galvanized and aging out, and laid out the plan. No scare tactics, just facts. The work was clean and they left the basement tidier than they found it.

Frequently Asked Questions

How do I know if my home has a lead water service line?

Homes built before the 1950s in the older neighborhoods are the most likely candidates. A plumber can often identify the material where the line enters the house: lead is dull gray, soft enough to scratch with a key, and usually has a bulb-shaped connection at the wall. The city has been replacing roughly 500 lead service lines in its distribution system with federal funding, but the portion on your property is your responsibility. If you are unsure, call (877) 401-2673 and we will check it for you.

Who is responsible for the service line, me or the city?

In general, the city owns the water main in the street and the line up to the curb stop; from the curb stop into your house is yours, including the service line itself. The same split applies to sewer laterals: the city maintains the main, you maintain the lateral from your house to the main. That is why a camera inspection of your lateral before it fails is money well spent.

What should I do before the first hard freeze?

Shut off the water to your exterior hose bibbs from the inside valve and drain them. Disconnect hoses. Insulate any supply lines in unheated spaces like crawlspaces, garages, and unfinished basements. Know where your main water shutoff is and make sure it actually turns. If a pipe does freeze, shut the water off and call (877) 401-2673 rather than trying to thaw it with anything that makes an open flame.

Why does my water pressure keep dropping in my old house?

In New London's older housing stock, the most common cause is internal corrosion of galvanized steel supply lines. They narrow over decades until fixtures barely trickle. A pressure test tells us whether the restriction is in your service line, the interior piping, or a single fixture. Sometimes the fix is as simple as a clogged aerator or a failing pressure regulator; sometimes the line is telling you it is done.

Do I need a sump pump if my basement has never flooded?

If your house sits in a low-lying area or near the river, past dryness is not a promise. Water tables shift, grading settles, and one bad nor'easter can find a path it never had before. A sump pump with a working check valve and a clear discharge route is inexpensive insurance. We test existing pumps too, because a pump that has not run in two years may not start when the water arrives.

What makes drains back up repeatedly in multi-family houses?

Usually a combination of more users than the original system was designed for and an aging line. Grease and wipes build up, cast iron scales, and old joints offset. Repeated snaking treats the symptom. A camera inspection finds the cause: a belly holding water, root intrusion, or a section of pipe that has collapsed. Then we can talk about a real fix instead of another temporary clearing.

How much does a typical plumbing repair cost here?

It depends on the job: the scope of the work, the materials involved, how easy the area is to access, the condition of the existing pipes, and whether it is scheduled work or something that cannot wait. A faucet cartridge replacement and a service-line replacement live in different worlds. What we do is diagnose first, then give you a clear picture of what drives the cost of your specific job before any work starts. Call (877) 401-2673 and describe the problem for a straight answer.

My water heater is in a damp basement. How long will it last?

Damp air, sediment from older supply lines, and tight clearances all shorten a tank's life. Flushing the tank yearly and replacing the anode rod when it is spent buys real years. If the tank is rusting at the base, rumbling from sediment, or producing rusty water, it is telling you the end is near. We service what is serviceable and replace what is not, sized to your household.
