Frozen pipe damage in Bothell: occasional, but real
.Frozen pipe damage in Bothell happens in cold snaps, not every winter. NOAA's 1991 to 2020 normals for the Seattle-Tacoma area, the nearest station we could read, show most freezing nights falling in November through March. Those normals list 5.8 days at or below 32 degrees in February, 3.0 in November and 1.9 in March, and no days at or below 0 degrees in any month.
A hard, multi-day freeze is unusual here, and many Bothell homes never see a pipe freeze. The ones that do usually have pipes in unheated places or a house left cold. For the more common causes of indoor flooding, see emergency water removal.
Where pipes freeze in homes here
.Exterior walls
A kitchen or bathroom sink on an outside wall has a supply line with little insulation between it and the cold. Seattle Public Utilities lists pipes near outer walls as vulnerable.
Crawl spaces and attics
These unheated spaces hold supply lines that sit in cold air for hours. The same utility names crawl spaces and attics among the common freeze points.
Garages
Lines to a garage laundry sink or water heater get no help from the house heat, and an open garage door makes it worse.
Hose bibs
Outdoor faucets are the first to fail. A hose left attached traps water in the faucet and the line behind it.
The thaw is when the leak shows up
.Ice in a pipe expands and can split the metal or a fitting, but the ice itself plugs the opening. Water often does not escape until the ice melts. That is why a quiet house can suddenly have the sound of running water behind a wall on the day the weather turns.
A trickle or no water at a tap is the usual sign of a frozen pipe. Keep the faucet open and warm the pipe slowly with a hair dryer, heating pad or warm towels. The National Weather Service says never to use an open flame. If the pipe has already split, see burst pipe water damage.
| What you see | What it points to |
|---|---|
| No water or a trickle at one tap in freezing weather. | Ice inside the line, not yet split. |
| Wet wall below a sink after the weather warms. | A split on an exterior-wall supply line. |
| Water pooling in a garage or beside the foundation. | A hose bib or garage line that cracked. |
| Wet ceiling after a cold week away. | An attic line in a house that went cold. |
Frozen pipe safety: what to do right now
.Find the main shut-off
Seattle Public Utilities says the valve is usually in a basement, crawl space or garage. Close it if water is flowing.
Do not use electrical devices in standing water
Seattle Public Utilities warns against electrical devices where there is standing water. Cut power at a dry panel or call your electric utility.
Thaw only a pipe that is not leaking
Use a hair dryer, heating pad or warm towels, never a flame.
Call a plumber for the pipe
The utility says to call a licensed plumber if you cannot find, reach or thaw the frozen section.
Call us for the water
Once the water is off, call the dispatch line for extraction and drying.
Pipe split after the thaw?
Call the 24/7 line. We start with the shut-off and the electrical check.
Vacation homes and cold garages
.A second home or a house left empty for a week is where a freeze costs the most, because the leak can run unseen for days. The Washington Office of the Insurance Commissioner says burst-pipe coverage generally applies as long as you heat your home properly. Seattle Public Utilities recommends a thermostat setting no lower than 55 degrees during freezing weather.
Before you leave, disconnect hoses, cover outdoor faucets and open under-sink cabinet doors. Ask a neighbor to look in if a freeze is forecast.
Our process after a freeze split
.Check the source
Water must be off and a plumber on the repair before drying begins.
Extract and pull wet materials
Pumps and extractors remove water. Wet pad and insulation come out.
Find hidden water
Moisture meters and a thermal camera trace water through wall cavities that look dry.
Dry the structure
Air movers and LGR dehumidifiers dry framing and subfloor, with readings logged.
Dry targets follow the published ANSI/IICRC S500 water damage standard, cited as a reference and not as a certification. Rebuilding is described on water damage repair.
What affects the cost of frozen pipe water damage
We explain scope and price before work starts.
Where the pipe split
A split in an open crawl space is simpler than one in a finished wall.
How long it ran
A split found at the thaw wets less than one found after a week away.
The materials involved
Drywall, flooring and insulation each need different treatment.
Access and drying time
Closed cavities and cold weather lengthen drying.
Pipe repair is a plumber's cost.
Mistakes to avoid in a cold snap
.- Using a torch or other open flame on a frozen pipe.
- Turning the heat off in a house you are leaving for days.
- Leaving hoses attached to outdoor faucets.
- Assuming a pipe that thawed on its own is undamaged.
We dispatch to Woodinville and Kirkland from the same line, so a cold snap that hits several cities is handled in order of urgency.
Common questions about frozen pipe water damage
Yes. The dispatch line is answered 24 hours a day, including nights, weekends and holidays. We offer same-day response when available and do not promise an arrival time. Close the main shut-off if water is flowing.
We could not find a Bothell weather station. NOAA's 1991 to 2020 normals for the Seattle-Tacoma area list days at or below 32 degrees from October through April, mainly November through March. Local conditions can differ.
The Washington insurance commissioner says policies usually cover burst pipes, including frozen pipes, as long as you heat your home properly. Report promptly and ask your insurer. We do not promise coverage.
It is worth looking. Check the pipe, its fittings and the wall or floor around it for dampness over the next day. A moisture meter reading can find a slow leak.
Only a pipe you can reach, and only with a hair dryer, heating pad or warm towels. The National Weather Service says never to use an open flame. If you cannot find or reach it, call a plumber.
