Crawl spaces and slow drying
Many homes sit over crawl spaces, where a slow leak can run for weeks unseen. Cool, damp air means wet materials do not dry on their own.
Bellevue sits between Lake Washington and Lake Sammamish, with a growing share of high-rise condos downtown alongside older single-family neighborhoods. This page covers what usually causes water damage here, what to do in the first hour, and how to reach an independent restoration company that serves your ZIP code.

Bellevue's housing spans several generations: about half homes predate 1980, while about a quarter were built in 2000 or later. In practice that means two different leak patterns: slow corrosion in older houses and sudden connection failures in newer ones.
With so many homes over crawl spaces, the first sign of a leak is often a smell or a soft floor rather than visible water.
About 41% of homes in Bellevue are in buildings with five or more units. In apartments and condos, water from one unit often reaches the unit below, so tell management or the HOA right away. The building's master policy and your own unit or renters policy may each cover a different part of the damage.
In condo towers, one leak can travel down several floors.

In the Puget Sound area the main shutoff is often in the crawl space, garage or basement where the line enters, with the city meter in a box near the street.
If the water came from a toilet, a sewer line or outside, treat it as contaminated: see sewage backup cleanup or flood water cleanup.

Washington homeowners policies typically cover sudden water damage, such as a burst pipe, but not flooding or slow seepage.

Independent restoration companies we connect callers with cover these Bellevue ZIP codes:
Start within 24 to 48 hours; the EPA says materials dried in that window are much less likely to grow mold. Humid air around Bellevue shortens that window, so don't wait for a dry day.
It depends on the age of the home. In Bellevue's older houses, corroded pipe and cracked drains are common. In newer homes, appliance hoses, water heaters and fittings cause most sudden leaks. Storms and roof leaks add to both.
