Shut the water off in five steps
Speed matters more than anything else in the first few minutes. Work through these in order.
- Find the main valve. It usually sits where the water line enters the house, often in the basement near the meter or the front wall. A round handle turns clockwise to close. A lever closes with a quarter turn.
- Close it fully. Turn until it stops. If the valve is seized, do not force it with a wrench, since a snapped stem makes things worse. Call us and say so.
- Drain the lines. Open the lowest faucet in the house, then the highest, so the pipes empty and stop dripping into the damage.
- Shut off the water heater. Turn the electric breaker off or set a gas unit to pilot. A tank that runs dry while heating can fail.
- Cut power near the water. If water is near outlets or the panel, leave the electrical shut-off alone unless the panel and your footing are dry.
Water is pouring from a pipe right now
This is the one plumbing problem where minutes show up on the repair bill. A burst line in a wall or ceiling can bring down drywall and soak insulation before you reach the main valve. We answer at night, on weekends and on holidays, because pipes do not split on a schedule.
Once the water is off, the situation is far calmer. The plumber arrives, finds the split, and cuts out the damaged pipe so you have running water again.
While you wait, protect what you can:
- Lift furniture, rugs and electronics out of the wet area.
- Place buckets under ceiling drips and poke a small hole in a bulging ceiling stain to let the water out under control.
- Photograph everything before you move it, for an insurance claim.
- Keep everyone away from a ceiling that sags or a floor that feels soft.
- Stay out of a flooded basement if the water is near the electrical panel.
Why pipes burst in a New England winter
Water expands about nine percent when it freezes. The ice itself does not usually split the pipe at the frozen spot. It traps water between the ice plug and a closed faucet, and the pressure climbs until the weakest point gives way.
In Massachusetts the risk is highest in unheated spaces: exterior walls, crawlspaces, garages, attics and the pipe run near a basement window. A cold snap after a warm week catches people off guard, and so does a vacant house with the heat turned down.
The burst often goes unnoticed until the thaw. The ice melts, the split opens, and water flows into a space you were not using. A sudden drop in pressure or a faucet that gives only a trickle on a freezing morning means a frozen section is already there.
Frozen but not burst yet
If a pipe is frozen and still intact, you may have time. Open the faucet it feeds so steam and meltwater can escape, then warm the pipe slowly with a hair dryer on low, starting near the faucet and working back toward the frozen area.
What to avoid:
- An open flame or a propane torch near a pipe or wall framing.
- Heat on a pipe that is already leaking, because it may be electrically live nearby.
- Waiting if the frozen run is inside a wall you cannot reach.
If you cannot reach the frozen spot, call. Thawing a line that has already cracked releases the water the moment the ice goes, and the plumber can have the shut-off ready when it does.
Copper, PEX or galvanized: what the split tells us
The material decides how the pipe fails and what the repair involves.
| Pipe | How it fails | Typical repair |
|---|---|---|
| Copper | A long split along the side of the tube, or a pinhole where the wall is thin | Cut out the section and sweat in new copper or a push-fit coupling |
| PEX | Stretches with freezing and may survive, but fittings can crack | Replace the damaged length or fitting. PEX tolerates a freeze better than rigid pipe |
| Galvanized steel | Corrodes from the inside, bursts at a threaded joint or a weak spot | Short repairs are possible, but a failed section usually signals more. See repiping |
| CPVC and other plastic | Becomes brittle with age or heat and cracks at fittings | Replace the section with new pipe and fittings |
What a repair looks like
We start by confirming the water is off and checking pressure in the lines that are still intact. Then we trace the damage back to its limits, since a pipe that froze in one place often froze in several.
A repair means cutting out the split section with a tubing cutter, usually leaving clean pipe on both sides, and joining in a new length. Copper is soldered or joined with a push fitting. PEX is crimped or expanded onto fittings. If the pipe is inside a wall, we cut a neat access opening, which is far easier to patch than a stained ceiling.
Before leaving, we turn the water back on slowly, bleed air from the lines and watch every new joint under full pressure. If one failure points to others, such as a corroded run, we show you why and what the next step would be.
Dial the 24/7 line. A plumber can usually be at the house the same day to cut out the damage and bring the water back.
After the water stops: drying out and what to document
Wet drywall and insulation start growing mold within a couple of days, and standing water behind baseboards is easy to miss. Open the affected cavity, run fans, and remove soaked insulation and carpet padding as soon as it is safe. A restoration company with drying equipment handles the structural side. We handle the plumbing.
Ask the plumber to save the failed section. It shows an adjuster how the pipe let go, and a clean split with no corrosion points to a sudden event.
Milford, MA: where the water comes from and who to tell
Milford Water Company supplies the town, which doses zinc orthophosphate and a pH adjuster to ease corrosion. That treatment slows wear on the inside of metal plumbing, but it does not stop a freeze, so insulation and heat in basements and exterior walls still matter.
A permanent repair that replaces supply piping needs a permit through the town, pulled by a licensed plumber. Milford posts a scam alert about fraudulent permit-fee emails and texts, so if a message asks you to pay a permit fee by link, do not click it. Questions about a real permit go to the plumbing inspector at Milford Town Hall.
A repair that replaces a section of supply piping is not a minor repair under the state's consumer guidelines, so expect the plumber to pull a permit and the inspector to check the work.
What shapes the cost of burst pipe repair
We state a clear price before cutting any pipe. The final number depends on:
Homeowner policies often cover water damage from a sudden burst but not damage from slow or long-term leaks, and some exclude vacant homes. Call your insurer promptly and give them the plumber's written findings.
For an honest read on your situation, call (508) 389-4045 and describe where the pipe failed.
Burst pipe questions, answered
Burst pipe calls are taken at every hour of the day and night. Tell dispatch whether the main is closed and where the water is coming from, and a plumber can usually be dispatched the same day to cut out the damaged section.
A frozen pipe gives no water or a trickle and may feel icy or show frost. A burst one adds sounds of running water, damp patches, or a spike in the meter reading. When the thaw starts, a hidden split announces itself with water.
Often it covers the resulting water damage from a sudden burst, though not the pipe itself. Policies differ on frozen pipes in vacant homes and on slow leaks. Photograph the damage, keep receipts, and ask your insurer before major cleanup.
Usually yes. A single split in sound pipe is a short repair. If the pipe is corroded or has failed in several places, we explain whether phased repiping makes more sense.
For an accessible split, usually a few hours. A pipe in a wall, or several damaged sections, takes longer. The plumber tells you the expected time once the damage is traced.
No. Milford Water Company supplies the water, but plumbing inside the house is the owner's to maintain. Ask the company where its side ends. If the break is outside, between the meter and the house, see our water service line page for who owns what.
If water is still running, stop reading and shut the main. Then ring (508) 389-4045, and dispatch will send a plumber to repair the damage.
Other jobs a burst pipe can lead to
When a split reveals old corroded pipe, the conversation often turns to repiping the house in phases. If the break is hidden and you are still chasing a wet spot, leak detection finds the source without guesswork. A burst line outside the house between the meter and the foundation is a water service line job. The same crews cover Bellingham and the surrounding towns.
