A line frozen in an exterior wall
Pipes against outside walls, especially on the north side, are the first to freeze. The water goes into the wall cavity, soaks insulation and shows up as a stain on the room's drywall.
Cleanup and drying after a cold snap splits a pipe in an exterior wall, garage, crawl space or unheated corner.

Frozen pipe water damage usually shows up when the thaw arrives: ice splits a line, and water floods out once it melts. Shut off the main, then call. Bowie Water Damage Restoration answers phones 24/7 and a crew is dispatched as fast as one is available; a plumber repairs the pipe and the crew dries the structure.
Ice does not usually burst a pipe where it forms. It builds pressure between the ice plug and a closed tap, and the pipe gives way at its weakest point. Until the thaw nothing leaks, which is why many owners discover the damage when the temperature rises, or when they come home from a trip to a ceiling already wet.
Winters around Bowie are cold enough to do this on the nights that matter. January lows average roughly 21 to 24 degrees Fahrenheit, and about 15 inches of snow falls in a typical year. The utility's numbers show how sharp the swings can be: WSSC Water logged 293 main breaks and leaks between November 26 and December 15, 2025, as the Potomac fell from about 49 to 32 degrees.
Those are street mains, not household lines, but the same cold reaches the pipes in your garage wall, your crawl space and the corner of the basement that never gets heat. This page covers what to do, what the crew does next, and how it differs from the general case in burst pipe water damage. Prevention is covered too, because most freeze losses are avoidable.
Turn off the main, open the affected tap, and thaw the pipe slowly with warm air, such as a hair dryer or a space heater kept well away from anything flammable. Never use an open flame. If a pipe is already split or water is showing, leave it alone, keep the main closed and call for help.
Warm the room first. Opening cabinet doors under a sink on an exterior wall lets heated air reach the pipe, and a modest increase in thermostat setting often does the rest. Work toward the faucet from the tap end so melting water has an exit.
Do not use a torch, a propane heater or a heat gun, which are common causes of house fires and can also damage the pipe. If you cannot reach the frozen section, a plumber can thaw it safely.
Keep a record of what you did and when, including the temperature and any photographs. It helps the plumber, the crew and, later, your insurer understand the order of events.
Keep the heat on at about 55 degrees Fahrenheit when you travel, open cabinet doors on exterior walls, let a tap drip during a hard freeze, disconnect outdoor hoses and insulate exposed pipes in garages and crawl spaces. Know where the main shut-off is so you can close it in seconds if something splits.
The weak points are predictable. Hose bibs, garage supply lines, pipes in a cantilevered bump-out and lines that run through an unheated crawl space freeze first. A small amount of foam sleeve or heat tape, installed before winter, protects most of them.
If you plan to be away, ask someone to check the house, or shut off the main and drain the lines. A house empty through a cold week is the setup behind many of the worst freeze losses.
While a pipe is frozen, ice blocks the crack and holds the water in. When the temperature rises and the ice melts, the split opens and the full pressure of the supply pushes water out. That is why a leak can seem to begin hours after the coldest night, often when no one is looking.
It also explains why a morning with low water pressure should prompt a quick walk through the house before the day warms. Look in the garage, the basement corners, the cabinets on outside walls and the ceilings below an unheated space.
If you find a split, shut the main at once. Water that has been running into a wall for an hour is far cheaper to dry than water that has run for a day.
The crew treats it like any water loss, with extra attention to cold exterior walls and unheated spaces that dry slowly and sometimes refreeze. It extracts, removes wet insulation, sets equipment, and rechecks readings. A house with no heat may need the furnace working or temporary heat so that drying actually proceeds.
Dehumidifiers work poorly in very cold air, so the crew may need the heating back on before drying equipment can do its job. If a power cut or a failed furnace caused the freeze, getting heat restored is part of the plan.
Cold also hides leaks. A wall that looks dry can hold ice in the cavity, so the crew checks again once temperatures rise and the ice has melted.
Do not use a torch, a propane heater or any open flame to thaw a pipe, and do not walk into a room where a ceiling is bulging with water. Close the main and call.
If you suspect a frozen line, shut off the main so that a split pipe cannot flood the house when it warms. Leave the affected tap open so melting water and pressure have somewhere to go.
Frozen sections often sit in exterior walls, garages, crawl spaces and ceilings under attics. A thermal camera and meters show the cold, damp path, and the plumber is told where to look.
Water is pulled from floors and carpet. Wet fiberglass in a wall or ceiling holds a large share of the water, and it is usually removed so the cavity can dry.
Equipment is set in the wet rooms and, if needed, ports are used to push dry air through closed cavities. Cold exterior walls dry slowly, so the crew allows extra time and rechecks readings.
A plumber repairs the split, and the crew's notes on where the cold got in help you decide on insulation, air sealing or heat for that run.
Pipes against outside walls, especially on the north side, are the first to freeze. The water goes into the wall cavity, soaks insulation and shows up as a stain on the room's drywall.
These areas are cold but easy to forget. Water pooling in a garage may be a minor mess, while the same split under a house with a crawl space can wet the floor above and the insulation below it. See crawl space water damage.
When a heating system fails in an empty house the line can run for days. These are the worst case, with water through several floors, so the crew works room by room and plans extra drying.
The hardest case to see. A split behind cabinets, tile or finished drywall can run for hours before the stain appears, so the crew works from the meter readings and the thermal camera to decide where the wall must open.
A freeze loss is priced the same way as any other water loss: by how much structure got wet, for how long, and what has to come out. Time matters especially here, because a line that ran unnoticed for days is a much larger job than one caught at once.
| Job | Typical range | What it includes |
|---|---|---|
| Emergency assessment | Confirmed on site | Meters and thermal imaging across every level |
| Extraction and wet-insulation removal | Confirmed on site | How long the water ran and how many rooms it reached |
| Drying equipment and monitoring | Confirmed on site | Cold walls dry slowly, adding days |
| After-hours or holiday dispatch | Stated before work starts | Freezes cluster on nights and holidays |
| Pipe repair | Separate quote | A plumber's job, quoted separately |
The price is confirmed on site for Prince George's County before work starts. Repairs to drywall, paint and flooring come after the structure tests dry.

Bowie and the surrounding towns see enough hard winter nights to make this a regular call each year, and the November-to-February stretch is when roughly 63 percent of WSSC Water's yearly main breaks and leaks happen. The utility also issued a one-day essential water use advisory in January 2025. A break on the main can drop pressure in the neighborhood without anything being wrong with your own plumbing.
Levitt-era houses in Belair at Bowie are now old enough that insulation around exterior walls and garages may be thin by modern standards, a general pattern rather than a measured fact for any one house. Hyattsville's older houses, built between the 1870s and the 1930s, often have additions and porches whose supply lines run through cold spaces. Those are the places to check before a forecast freeze.
Outside the WSSC area, Anne Arundel and Howard county towns have different water utilities. Check your bill so you know who to call about a street main and who stands behind your own line.

WSSC Water reports that about 63 percent of its roughly 1,800 yearly main breaks and leaks happen from November to February, and about 42 percent of its mains are over 50 years old.
No. Many freeze and thaw without splitting, and a small crack may weep slowly rather than flood. Even so, a pipe that froze is weakened, so watch it closely after it thaws and have a plumber look if the pressure or meter behaves oddly.
In a hard freeze, a slow drip from a tap on an exterior wall keeps water moving and reduces pressure build-up. It will not protect a pipe that is badly exposed, so combine it with open cabinet doors and some insulation.
Often three to five days for a room, and longer for cold, thick or masonry walls. Cold air carries little moisture, so the crew may need temporary heat. The readings, not a timetable, decide when equipment can leave.
A plumber repairs it, and in Prince George's and Montgomery counties plumbers are expected to be registered with WSSC Water. The restoration crew handles extraction, drying and cleanup and can tell the plumber what it found.
That is your insurer's decision under your policy. Many policies treat a sudden freeze-and-burst differently from a long-term leak or from flood, but the wording varies. Photos, the moisture record and prompt notice help.
Keep the main closed and leave the affected tap open. A pipe that is split but still iced over will release water at full pressure as it thaws, so call a plumber to repair it before the main is turned back on.
