Burst pipes in Beaverton homes

Cold air pushing west from the Columbia Gorge, with moist Pacific air above it, produces freezing rain over the Portland metro, including Washington County. February 2021 brought heavy snow and up to an inch and a half of ice in parts of the state. ^[1] Trees fall, power fails and houses cool until pipes in crawlspaces, garages and exterior walls freeze.

When the power returns and the house warms, split pipes leak. See our main burst pipe water damage page for the mechanics.

Braided supply lines to toilets and faucets, washing machine hoses, ice maker tubing and water heater connections wear out on their own schedule, regardless of how new the house is. In two-story suburban homes, those fixtures are often upstairs, so a failure sends water through the ceiling below within minutes.

Older houses in the original centres of Beaverton, Hillsboro and Forest Grove may have galvanised or older copper plumbing in less protected spots. Galvanised pipe rusts from the inside and fails at threads. Those homes also may have lead paint or asbestos, so ask before walls are opened. See the Beaverton area page.

Leak sensors under sinks, behind toilets and by the washer and water heater sound an alarm or send a phone alert when wet. An automatic shutoff valve on the main closes when it detects a leak. In a two-story home with upstairs laundry, it can turn a ceiling collapse into a puddle.

Sudden pipe bursts are commonly covered. Keep the failed part and the plumber's invoice. Check the contractor with the Construction Contractors Board.

When water appears in a downstairs ceiling, the source is usually directly above: a toilet supply line, the wax ring, a sink supply, a tub drain or a washer hose. Sometimes it is a pipe in the wall or floor between. Thermal imaging and moisture meters trace it before anything is opened, so the repair hole is in the right place.

Once the plumber fixes the line, drying covers every layer: the upstairs subfloor, the ceiling cavity and the room below. If water reached the crawlspace, the floor system is dried from below too. Readings decide when each is done.

Many suburban homes keep the water heater in the garage, where an ice storm can freeze its connections and age can corrode them. A drain pan, a leak sensor and keeping the garage door closed in freezing weather reduce the risk.

Older houses in the town centres of Beaverton, Hillsboro and Forest Grove were often built before 1978. Painted surfaces may contain lead and some materials may contain asbestos. Ask about testing before walls or ceilings are opened.

A burst in a shared or exterior wall of a townhouse can send water into the neighbouring unit. Tell neighbours and the HOA right away, and photograph damage on both sides. The master and unit policies decide who pays for what.

Find the main shutoff before you need it and make sure everyone in the house knows where it is. In many suburban homes it is in the garage or near the front hose bib.

Ask the plumber whether other exposed lines should be insulated or rerouted, and whether any aging supply lines elsewhere in the house are worth replacing while they are there. A line that froze once sits in the same cold spot next winter.

When a burst floods the crawlspace, pumping comes first, then wet insulation is removed and the floor system dried with a desiccant unit and air movers. Insulation goes back only when readings match dry wood.

An automatic shutoff valve on the main, triggered by sensors or unusual flow, closes the water within moments of a burst. Some insurers recognise these devices. A plumber can say which type suits your house.
