Water Intrusion in New Homes Before They're Even Finished

New homes are vulnerable to water intrusion long before the final coat of paint. Open roof sheathing, unsealed windows, and exposed framing can let rain and wind-driven moisture inside. Even a mild marine climate with wet winters and dry summers can cause problems if construction pauses during a rainy stretch.

Plumbing rough-ins and HVAC ducts may sit open for weeks. A sudden storm or a burst pipe during installation can saturate insulation, drywall, and wood. The key is that water damage is not always visible right away, so you need to look carefully at every stage.

Schedule a water damage inspection before the drywall goes up and again before final finishes. A pro can use moisture meters to detect hidden dampness in framing and insulation. You can also ask the builder to show you the drainage plan and test the roof with a hose if weather permits.

Keep a written log of any water events during construction, such as a heavy rain or a pipe leak. Photos help document what you saw. If you live in Kirkland, keep your shutoff valve location written down in case of a burst pipe.

Once the home is finished, keep gutters clean and downspouts extended away from the foundation. Check the roof annually for loose shingles or cracked flashing. In crawlspaces, make sure the vapor barrier stays intact and that vents are not blocked.

If you notice musty odors or stains on ceilings or walls, investigate right away. The pros can perform a crawlspace water cleanup or attic repair if needed. Catching a small leak early can save you from major restoration work later.
