Frozen pipe burst cleanup for homes in central and northeast Maryland
Most winters in this corridor bring at least a few nights well below freezing, and that's when pipes in exterior walls, crawl spaces and garages split. The water usually arrives when the ice melts. We connect you with local crews who handle the thaw-day call.

What to do right now
If water is running, close the main
Shut the main valve where the supply enters the house. A split pipe that's thawing will keep releasing water until the main is closed.
If a tap won't run, suspect ice
No water, or a trickle, from one fixture on a very cold morning usually means a frozen section. Leave that tap open so pressure can escape as it thaws.
Leave thawing to a plumber
Open flames and improvised heat sources near pipes and framing cause their own problems. A plumber has the right tools, and can check for a split before water goes back on.
Keep clear of electrics near the break
Frozen lines often run through basements and garages near panels. If water is near outlets or panels, do not enter and call your utility and emergency services.
Check the rest of the house
If one line froze, others in similar spots may have too. Look at every exterior wall with plumbing, the crawl space and the garage.
Photograph the split
Before the plumber cuts it out, take a picture of the damaged section and where it runs.
We'll help you tell a frozen line from a broken one.
Call and We'll Walk You Through ItWhy frozen pipes burst
Water expands as it freezes. When a section of pipe freezes solid, the ice itself isn't usually what splits the pipe. It's the pressure building in the water trapped between the ice plug and the closed faucet at the end of the line. That pressure has nowhere to go, and the pipe gives at its weakest point, often some distance from the ice.
While the line stays frozen, the split is sealed by ice and nothing leaks. The water comes when temperatures rise: the ice melts, pressure returns, and the split starts running. That's why frozen-pipe calls cluster on the first mild day after a cold spell, sometimes days after the actual freeze.
The timing, plainly
A pipe can break at 3 a.m. on the coldest night and not leak until the afternoon it warms up. If you've had a hard freeze, check vulnerable lines before the thaw, not after.
Signs of a frozen or burst pipe
- A faucet that gives no water or only a trickle on a very cold morning
- Frost visible on an exposed pipe
- A toilet that doesn't refill
- A bulge or visible split in a pipe
- Water appearing in a garage, crawl space or exterior wall as temperatures rise
- Water spraying from an outdoor faucet when it's turned on for the first time in spring
That last one surprises many people. A hose left attached to an outdoor faucet over winter can trap water inside the valve body, which freezes and splits inside the wall. It doesn't leak until someone turns the tap on in April.
Where pipes freeze in houses here
Exterior walls
Kitchen sinks on outside walls, bathrooms over garages and laundry rooms in bump-outs are the classic spots. Older houses often have little or no insulation in those walls.
Crawl spaces
Additions and some older houses sit over vented crawl spaces that get close to outdoor temperature on a windy night.
Garages and unheated spaces
Supply lines to a garage sink, a laundry in the garage, or a bathroom above an unheated garage are exposed to cold from below.
Outdoor faucets
Hose bibs and their supply lines, especially older ones without frost-free valves, or frost-free ones with a hose left on.
Attics
Occasionally supply lines run through attics in townhouses or remodeled homes, where they're exposed to near-outdoor temperatures.
Vacant and lightly heated homes
Homes between tenants, second homes and houses where the heat has been turned right down for a trip are among the most common frozen-pipe losses, and often the most extensive, because nobody sees the water for days.
The first hour
Once the main is shut, go through the house and find every place water went. Winter breaks in exterior walls often leak into the cavity before they show, so look for stains, wet baseboards and damp carpet along outside walls, and check the rooms below. Call a plumber for the repair, and a restoration crew for the water.
In townhouses, condos and apartments
A burst line in an end unit's exterior wall or in a shared utility space can affect neighbors. Tell the management office and the units next to and below you. If a neighbor's unit is empty and you see water, the office can arrange access.
For landlords and property managers
Vacant units are the highest-risk spaces in a cold snap. If a unit sat empty through a hard freeze, it's worth walking it on the first mild day before water has time to spread.

Managing a Building? Call UsHow frozen pipe cleanup is done
Confirm the water is off and the break found
If the plumber hasn't been yet, the crew makes sure the affected line is isolated.
Extract
Standing water is removed from floors, carpet and, where needed, crawl spaces.
Open the exterior wall
Breaks inside exterior walls usually mean opening drywall along the pipe run, removing wet insulation and exposing the cavity to dry.
Check below and beside
Readings in rooms under the break and in neighboring units find water that traveled.
Dry in winter conditions
Cold air holds less water, so drying setups in winter often add heat or use desiccant dehumidifiers that keep working in cool spaces.
Monitor and document
Daily readings, a record of what was opened and removed, and final numbers before repairs.
What affects time and cost
- How long water ran after the thaw before it was found
- Whether the break was in an open basement or inside a finished wall
- How many floors or units it reached
- Crawl space access and conditions
- Winter drying conditions, which can add time
- More than one break in the same house
Pricing for cleanup and drying comes before work starts. The pipe repair is the plumber's, and wall and ceiling repairs follow once the space is dry.
Winter cleanup priced before anything is opened.
Call for Upfront PricingKeeping it from happening again
A house that froze once will freeze again in the same spot unless something changes. Ask the plumber whether the pipe can be rerouted to an interior wall, or insulated and protected. While the wall is open for drying, it's the easiest time to add insulation on the cold side of the pipe.
- Disconnect hoses from outdoor faucets before the first freeze, and shut off and drain any older hose bibs from inside
- Keep cabinet doors under sinks on exterior walls open on very cold nights
- Let a vulnerable tap drip during a deep cold snap
- Keep the heat on in vacant units and when you travel, and have someone check the house
- Seal gaps where cold air reaches pipes in crawl spaces and rim joists

Questions
Frozen pipe questions
There's no single number. It depends on how exposed the pipe is, how long the cold lasts and whether wind is reaching it. Pipes in uninsulated exterior walls, crawl spaces and garages are at risk in a hard freeze that lasts overnight or longer, which happens most winters here.
Not necessarily. It may just be frozen. Leave the tap open, keep the space as warm as you normally would, and call a plumber if it doesn't return. Watch for water as it thaws, because a frozen section can split without any sign until the ice melts.
Pressure builds in the water trapped between the ice and the closed faucet. The pipe gives at its weakest point in that stretch, which may be a fitting or a thin spot some distance from the ice itself.
Water left in the valve body, often because a hose was still connected, froze and split the pipe inside the wall. It stays sealed until someone opens the tap, and then water runs into the wall or basement. Checking inside after first use in spring catches it early.
Sometimes, if the leak was brief and readings show only the drywall surface is damp. More often, insulation in exterior walls holds water against the framing and sheathing, and the wall has to be opened to dry. The crew decides from readings rather than guessing.
It can. Cold air holds less moisture, and refrigerant dehumidifiers slow down in cool spaces. Crews compensate with heat, desiccant dehumidifiers and containment. A warm interior room usually dries on a normal schedule; a cold crawl space or garage may take longer.
Keep the heat on at a moderate setting, open cabinet doors under sinks on exterior walls, and disconnect outdoor hoses. Many people also close the main shutoff while away. Having someone check the house during a cold snap catches problems early.
Less often than in houses, but yes: end units, top floors near the roof, units over unheated garages or breezeways, and vacant units with the heat off. When they do, water often reaches units below. The management office should hear about it right away.
The cleanup is similar: extraction, opening wet areas, drying and documentation. The differences are timing, since it's usually found at the thaw, and location, since breaks tend to be inside exterior walls and crawl spaces. Winter conditions also change how drying is set up.
