Homes in Seattle and how they leak

Craftsman homes and bungalows from the early 1900s fill the older neighborhoods, on crawl spaces or daylight basements built into slopes. Newer townhomes and condos are packed onto infill lots. Many older homes have original clay or concrete side sewers.

Local issues that cause water damage

Crawl space and basement water

Months of saturated ground push water under and into homes. See crawl space drying.

Tidal and river flooding

In December 2022 a king tide and storm flooded homes in South Park along the Duwamish River.

Freeze bursts

Occasional hard freezes burst pipes in a city where plumbing is not well protected.

Questions from Seattle homeowners

Why does my side sewer back up?

Old clay and concrete pipes crack and fill with tree roots. A camera inspection shows whether it needs cleaning, lining or replacement.

Is a damp crawl space normal in Seattle?

Common, but worth fixing. Standing water and wet soil raise humidity under the floor and lead to mold and rot.
