Frozen Pipe Burst in Marysville, WA

Speed matters with a frozen pipe burst in Marysville because the worst of it often comes in waves. Several pipes can freeze in the same cold snap, and each one starts leaking as it thaws, sometimes days later when the weather turns to rain and melt, as it did around Christmas after the December 2022 snow and cold. A split line in a vented crawlspace soaks the insulation and vapor barrier, then the subfloor and floor joists above. A hose bib or supply line in a garage wall sends water across the slab and into drywall and stored boxes. Cold, damp winter air also slows natural drying to a crawl.

In the first hour after a thaw, water runs freely from the split, soaking insulation, pooling on the vapor barrier or spreading across the garage floor. By 24 hours the subfloor and the bottom of the garage drywall have wicked water, and wet insulation sags off the joists. At 48 hours mold can begin on wet wood, drywall paper and cardboard boxes. After a week, a crawlspace that was never dried smells musty through the floor registers, subfloor panels start to swell, and stored items in the garage are often a loss.

Water from a frozen line is clean when it first comes out, so much of the structure can be dried in place. Floor joists, rim boards and sill plates in the crawlspace usually dry well once wet insulation is pulled and dehumidifiers run in a closed-up crawlspace. Plywood and OSB subfloor dries from below while air movers work the room above. In a garage, the concrete floor dries quickly once standing water is removed, and drywall that wicked only a few inches can sometimes be dried by removing the baseboard and venting the cavity behind it.

Wet fiberglass insulation under the floor is almost always replaced, because once it sags and mats down it holds water against the wood and stops insulating. A torn or puddled vapor barrier is usually replaced too. Garage and exterior wall drywall that sat wet gets a flood cut, and wet insulation in that wall comes out with it. Cardboard boxes, particleboard shelving and anything stored on the garage floor often cannot be saved. If the water sat for days before anyone found it, the crew treats the crawlspace as category 2 and removes more.

Frozen pipe calls follow the cold snaps across Marysville. Older homes near Downtown and Jennings Park may have crawlspace lines and hose bibs with little insulation around them, and those are often the first to freeze. In 1990s homes in Smokey Point and Lakewood, a typical example is a hose bib or supply line inside an exterior garage wall that splits and floods the garage floor. In the 1970s and 1980s suburbs north and east of downtown, lines that run past crawlspace vents are a common weak spot when the wind pushes cold air under the house.

The same cold snaps hit nearby towns hard. Arlington dropped to 6 degrees below zero in December 2008 and to about 7 degrees in January 2024, and that same January cold burst pipes in Stanwood and Camano Island schools, including Utsalady and Elger Bay elementaries. Homes in Arlington, Stanwood and on Camano Island see the same crawlspace and garage breaks. Call the number on this page and you are connected with a local restoration pro who serves your area.
