Months of steady rain
The rainy season is long rather than violent. Gutters, downspouts and grading that send water toward the house slowly soak crawl spaces and basements, and atmospheric river storms like November 2021's add flooding on top.
Tacoma has some of the oldest housing in the Puget Sound region, with a third of homes built before 1960. 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.
We are a referral service, not a contractor. Your call is connected to an independent company that covers Tacoma. How it works
Tacoma's housing spans several generations: more than half homes predate 1980, while about one in six were built in 2000 or later. That means the likely cause of a leak depends a lot on the house. Older homes tend to have corroded supply pipe and cracked drains, while newer homes see more failures at hoses, fittings and water heaters.
Crawl spaces are common here. Water from a leak or from poor drainage collects under the house, soaks the insulation and raises humidity in the rooms above.
Old supply pipe, aging sewer laterals and damp basements are common sources of damage.

See the full list of regional water risks, and every city we cover nearby, on our Washington page.
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.
The oldest housing in the area we cover is in 98403, where the median home was built in 1938. The newest is in 98421, with a median of 2017. Older ZIP codes tend to see more corroded pipe and drain failures; newer ones more appliance and fitting leaks.

Washington homeowners policies typically cover sudden water damage, such as a burst pipe, but not flooding or slow seepage.
The Washington page covers state insurance rules in more detail, and our claims guide explains how to document a loss.
Each guide below explains one kind of water damage and how it is handled.
Independent restoration companies we connect callers with cover these Tacoma 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 Tacoma shortens that window, so don't wait for a dry day.
It depends on the age of the home. In Tacoma'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.
Calls from 98402, 98403, 98404, 98405, 98406, 98407, 98408, 98409, 98416, 98418, 98421, 98422, 98433, 98443, 98444, 98445, 98446, 98447, 98465, 98466 are routed to independent restoration companies that serve those ZIP codes. We are a referral service and don't do the work ourselves.
Say where the water came from and how long it has been wet. That's usually enough to plan the next step.
