Why pipes fail in Lynnwood houses
Most Lynnwood winters are mild and wet, which is exactly why a hard freeze catches people out. When an arctic air mass settles over Puget Sound for a few days, pipes in exterior walls, garages, crawl spaces and unheated bonus rooms are the first to freeze. The leak usually shows up when the pipe thaws, sometimes days later.
Age causes more failures than cold. Houses built in the 1960s and 70s may still have galvanized steel lines that rust from the inside, plus plastic supply lines under sinks and toilets that get brittle with time. Washer hoses, fridge lines and water heaters round out the list.
What a crew does after a pipe break
- Confirms the water is off and tells you whether you need a plumber to make the repair.
- Extracts standing water and pulls wet carpet pad.
- Opens up drywall or ceiling panels where water is trapped behind them, so the cavity can dry.
- Sets drying equipment and checks readings until the framing is back to normal moisture.
- Photographs and logs everything for your insurance claim.
Where the pipe ran matters. A break inside a wall or ceiling spreads water out of sight, so crews cut small inspection holes and use meters before deciding how much to open up.
Pipe breaks we hear about in the Lynnwood area
The calls follow the housing. In the older neighborhoods around Lynndale, Meadowdale and Cedar Valley, it is often a galvanized line that rusted through, or a water heater in a hall closet that leaked into the carpet. In newer townhomes and apartments near Alderwood and City Center, it is more often a supply line under a sink, a washer hose or a sprinkler line in a unit that sits above other units.
Cold snaps add a burst of calls in December and January. Pipes in crawl spaces with torn insulation and in garages with an exterior wall freeze first. If you lose heat or leave town during a freeze, leave the heat on low and open the cabinet doors under sinks on outside walls.
