Why crawl spaces get wet here

Crawl space water signs in Sammamish, WA

Rain that cannot soak in

Dense glacial till under much of the plateau drains slowly, so water from a long rain perches on it and runs sideways toward the foundation.

Leaks no one sees

A dripping supply joint or a cracked drain line under the floor can soak the vapor barrier and insulation for weeks before a stain shows upstairs.

Damp air rises

Water under the house raises humidity in the rooms above, which brings a musty smell and cupped wood floors. Damp materials can start growing mold within 24 to 48 hours.

How do I check my crawl space safely?

Look in from the access hatch with a flashlight first. If there is standing water, a strong odor or any sign of sewage, stay out and call.

Is a little water under the house normal after rain?

Some dampness on bare soil is common, but standing water or a soaked vapor barrier is not, and it keeps the joists and subfloor wet.

Why is wet insulation a problem?

Wet batts get heavy, sag and stop insulating, and they hold water against the subfloor. They are usually removed, not dried.

Who fixes the drainage?

A drainage or foundation contractor handles grading, downspouts and drains. The restoration team extracts the water and dries the crawl space with daily readings.

Will insurance cover water in a crawl space?

Many policies treat a sudden pipe leak differently from groundwater or runoff. Coverage depends on your policy, so check with your own insurer.

Water under the house? Get it dried before it spreads.
