Frozen Pipe Repair in Mount Laurel, NJ Homes
If a faucet runs dry in a hard freeze, the pipe has probably frozen but not yet split. Here is how to thaw it slowly, how to check for damage, and when to hand it to a plumber.
Thaw it slowly and keep the faucet open
When water stops at one tap during freezing weather, ice has formed somewhere in the line between the shutoff and that faucet. Frozen pipe repair that does not involve a split is mostly patience and gentle heat. Open the tap first so melting ice and steam have a way out.
Start on the faucet side of the frozen stretch and work back toward the shutoff. A hair dryer on low, a heating pad wrapped around the pipe, or towels soaked in hot tap water all work. Expect it to take an hour or more before full flow returns.
Stay close while you do it. A pipe that cracked when it froze will not leak until the ice melts, and you want to be standing next to the main shutoff when that happens.
Five moves from a dry faucet to running water
- Find the main shutoff and turn it once. Confirm the valve actually moves before you need it in a hurry. A stuck valve is something you want to learn about now.
- Open the affected faucet, hot and cold. An open tap relieves pressure behind the ice and shows you the moment water starts to move.
- Look along every exposed pipe. Check the basement, garage walls, crawlspace and the cabinet under the sink for bulges, cracks or white frost. Splits often show before any water does.
- Warm the pipe a little at a time. Work from the tap toward the cold section. Never rush it with a flame, because a pipe heated unevenly can fail at the hot spot.
- Run water and watch for ten minutes. When flow returns, let it run, then check the pipe, the ceiling below it and the wall behind it for drips or darkening paint.
Three habits that turn a freeze into a flood
Do not use a torch, propane heater or any open flame on a pipe. Wood framing behind a wall catches fire, and a heater in a closed space can produce carbon monoxide. If the pipe is near the electric panel, an outlet or the water heater, keep standing water away from anything electrical and switch off that breaker only if you can reach it dry.
Do not keep heating a pipe that has started to leak. Close the main shutoff, open a low faucet to drain the line, and call the 24/7 line.

Call (609) 547-1417What you see and what it usually means
| What you see | Likely cause | Next move |
|---|---|---|
| One tap dry, others fine. | Ice in a branch line. | Thaw slowly with the tap open. |
| Every tap dry, street normal. | Ice near the main entry or meter area. | Check the entry pipe, then call if you cannot reach it. |
| Bulge or crack on the pipe. | Ice has split the wall. | Shut off water and call a plumber before thawing. |
| Wet drywall or stain below a pipe run. | A split that already thawed. | Shut off water and call right away. |
| Slow or backed up drain in the cold. | Frozen trap or vent line. | Call, because heat on drain lines is easy to misjudge. |
Copper tends to split along its length when ice expands. Plastic lines are more forgiving, but fittings and joints can still fail.
Why some Mount Laurel pipes freeze and others never do
Freezing is almost always about where a pipe runs, not how new the house is. Lines in an exterior wall, an unheated garage, a crawlspace or the rim of a basement lose heat first. A kitchen sink on an outside wall is a classic spot, because the cabinet door keeps warm room air away from the pipes.
The same steps apply from Mount Laurel to Moorestown and Cherry Hill. If a freeze has already cracked a line, a plumber will treat it as a burst pipe repair job, which means cutting out the damaged section and replacing it, not just patching.
Some splits stay hidden inside a wall. In that case a pressure check or a listening tool can find the leak before you open any drywall, and that is the point of leak detection after a hard freeze.
When the whole street is dry, it is not your pipe
Local note
Public water in Mount Laurel comes from the Mount Laurel Township Municipal Utilities Authority and, in part of the township, from New Jersey American Water. In January 2014 the authority asked residents to limit water use for about 12 hours while crews repaired a major sewer line break. That was a sewer problem, not a supply failure, but it shows that a January water problem is not always inside your walls.
Before you start thawing, ask a neighbor if their water is normal and check one more faucet in a different room. If only your house is affected, work the steps above. If a sewage backup shows up in a low drain, report it to the authority and then call us.
Cheap fixes that keep the next freeze away
- Disconnect garden hoses and shut off the indoor valve to outdoor spigots before the first hard freeze.
- Open cabinet doors under sinks on exterior walls when the forecast drops.
- Let a faucet drip on the coldest night, using the tap farthest from the main shutoff.
- Wrap exposed pipes in a garage or crawlspace with foam sleeves.
- Seal air leaks around pipes where they pass through the rim joist.
- Keep the thermostat steady, even when you travel.
None of this is a guarantee against freezing, but together they remove the most common causes.
Where a homeowner should stop and call
Call if you can see a split, if water is coming through a ceiling or wall, if the frozen section is behind a wall you cannot open, or if the main shutoff will not turn. Call too if you thawed the pipe and the pressure or flow stays weak. That can mean a second freeze point or a partial crack.
A plumber cannot always tell by phone whether a pipe has split, so expect a visual check and a pressure test before anyone says the line is sound. Frozen pipes do not wait for business hours, and the 24/7 line takes calls on cold nights, weekends and holidays. Call (609) 547-1417 and say where the pipe froze and whether water is flowing.
Frozen pipe questions from Mount Laurel homeowners
It is better to use hot tap water on towels or a hair dryer on low. Boiling water can crack a pipe that is already stressed. Always keep the faucet open while you thaw.
Look for a bulge, a hairline crack, wet insulation or a stain below the pipe once ice melts. If water flows weakly after thawing, a split may be hiding in a wall. A pressure check from a plumber can confirm it.
Insurance coverage for a freeze burst depends on your policy, so ask your agent before assuming. Take photos and keep the receipts.
Yes, on the coldest nights. Moving water is harder to freeze, and a drip also relieves pressure if ice does form. Choose the faucet farthest from where the main enters the house.
Ask neighbors first. If the whole street is affected, contact your water supplier, which is the Mount Laurel MUA or New Jersey American Water depending on your address. If only your home is dry, call us and we will look at your lines, including Evesham or Medford addresses nearby. Replacing the split section, rather than patching it, is the lasting fix.
