If you have a frozen or burst pipe in Lawrence, MA, the first move is to shut off the main water valve. A frozen pipe is blocked by ice and may still be intact. A burst pipe has split and is releasing water. Either way, stopping the supply keeps a small problem from becoming a flooded floor.
This guide gives the order of steps, how to tell the two situations apart, and what the city does and does not cover.
Frozen or burst? How to tell in a minute
The two look different, and the next move depends on which one you have.
| What you notice | Most likely | First move |
|---|---|---|
| No water at one or more taps, no leak anywhere | Frozen, pipe still intact | Shut main, open the tap, start gentle warming |
| Water stains growing on a ceiling or wall | Burst or split pipe | Shut main, drain the lines, call |
| Sound of running water with every tap closed | Active leak somewhere | Shut main, check the meter |
| Frost on an exposed pipe, weak flow | Partly frozen | Keep a trickle, warm the area |
| Water spraying or pooling at a fitting | Joint failure or split | Shut main, kill power nearby |
A pipe can freeze solid and burst later as it thaws. Treat any frozen pipe as a possible leak.
The order that limits damage
Do these in sequence. Each move protects the next one.
Close the main water valve
Find it where the line enters the house, often in the basement near the meter. Turn it fully closed. If it will not turn, that is a reason to call right away.
Drain the pipes
Open the faucets, starting at the highest floor, and flush a toilet or two. This takes pressure off the damaged section and pulls remaining water out of the lines.
Cut power near the water
If water is near outlets, the panel or an appliance, switch off the breaker for that area from a dry spot. If you must stand in water to reach it, do not. Call the utility or an electrician.
Move belongings and call
Lift rugs, boxes and electronics off the floor. Then call a licensed plumber for the repair. Take photos of the damage before you clean up.
While you wait for the plumber
These small jobs reduce the damage and help the plumber work faster.
Catch and divert
Place buckets under drips. Cut a small hole in a bulging ceiling, over a bucket, so trapped water drains instead of pulling the plaster down.
Warm a frozen section gently
Open the tap, then aim a hair dryer on low at the pipe, working from the tap back toward the frozen spot. Never use a torch or open flame.
Take photos and notes
Photograph the pipe, the wet area and damaged items. Write down the time you found it. Your insurer will ask.
Do not use the water heater
Turn the heater to its lowest setting or off if the tank may have lost water. Running a heater dry can damage the element or the tank.

What Lawrence does and does not cover on a frozen line
The city's rules say it repairs the service line from the main to the curb stop, and the owner handles everything from the curb stop onward. The city web page words this differently, saying up to and including your meter, so confirm with Lawrence Water & Sewer at 978-620-3110 before you assume anything.
The rules also say the city assumes no responsibility for frozen service lines, and the Water Department is not responsible for the customer's service line or meter. City freeze guidance is to keep the thermostat at 55 F or higher, insulate exposed pipes and call a plumber. So a frozen line to your house is a private repair.

Thaw it yourself or call for a repair
Some cases are reasonable to handle yourself while you wait. Others carry too much risk.
Reasonable to try yourself
- A visible, accessible pipe along a basement wall with no leak
- Opening taps and warming the room with a space heater placed safely away from water
- Wrapping exposed pipe in insulation once it flows again
- Shutting off the main and draining the lines
Call a licensed plumber
- Any pipe that has split, bulged or sprays water
- A frozen line inside a wall or under a slab where you cannot see it
- A frozen main between the curb stop and the meter
- Any repair that cuts, replaces or solders pipe, since that work needs a permit
Massachusetts rules treat only minor leak repairs and clearing a clog as permit-free. Replacing or repairing a burst section is licensed work, which is why a licensed plumber should do it. For splits that reach long runs, our burst pipe repair crews can replace the damaged section, and a failed outdoor or main line may be a water line repair job.
Winter weather in the Merrimack Valley
NOAA climate normals for the Lawrence station put the January average low at 19.6 F. That means some nights are well below the average, and a pipe in an unheated garage, crawl space or exterior wall can freeze on those nights. Pipes along north-facing walls and near rim joists tend to freeze first.
A few habits help. Keep cabinet doors open on exterior sink walls, let a faucet drip on the coldest nights, and seal drafts at the rim joist. If you are leaving for several days, keep the heat on instead of shutting it off. According to Massachusetts insurance guidance, sudden and accidental pipe bursts are typically covered when the home was heated and occupied, so document the damage before cleanup.
Insurance after a burst pipe
The Massachusetts Division of Insurance says burst-pipe damage is typically covered when it is sudden and accidental and the home was heated and occupied. A pipe that leaked slowly over weeks may be treated differently, so ask your agent about gradual leaks.
Document the damage, keep receipts for emergency repairs, and do not throw away a damaged section of pipe until your adjuster has seen it. Landlords and tenants should both notify each other quickly.
Frozen and burst pipe questions from Lawrence homes
Lawrence's rules put the owner's responsibility at the curb stop and beyond, and say the city is not responsible for frozen service lines. Confirm the exact line with Lawrence Water & Sewer at 978-620-3110 before you hire anyone.
A frozen pipe is blocked by ice and often still sealed. It can split as the ice expands or as it thaws. Treat any frozen pipe as a pipe that may leak and keep the main valve close at hand.
Yes. Closing the main before the pipe thaws means a hidden split will not start spraying when pressure returns. Reopen it slowly after the thaw and check for drips.
Yes. Tell your landlord at once, shut off the unit's water if you can reach a shutoff, and photograph the damage. Massachusetts rules say a lack of sufficient water for 24 hours or more endangers health and safety.
Our 24/7 line takes calls around the clock for burst and frozen pipes, and same-day appointments are offered when available. Shut off the main valve and call right away so we can dispatch.
