Crawl Space Mold Removal in Kenmore, WA

How it works

The number here reaches an independent mold remediation company serving Kenmore and the Northshore; this site doesn't do inspections or cleanup. Tell them what led you to call: a smell in a bedroom, mold spotted during a home inspection, a dropped batt, or water under the house after a heavy rain. They'll set up a visit, and a good one includes a full trip through the crawl space, moisture readings in the wood, and a look at vents, the ground cover, plumbing and the exterior grade. Ask to see the photos before you agree to anything.

Where the money goes

Angi's Seattle cost guide puts crawl space mold removal at $425 to $1,650, with labor around $75 to $120 an hour. HomeGuide's 2026 national range for crawl spaces is $1,500 to $4,000. In practice the price reflects:

• the size of the crawl space and the share of framing affected
• how much room there is to work
• bagging out and replacing insulation
• a new vapor barrier, vent covers or downspout fixes
• a dehumidifier if the space is sealed

Kenmore specifics

Kenmore is a Northshore city about 10 miles from Seattle, best known for Kenmore Air Harbor and the spot where the Sammamish River flows into Lake Washington. King County says the river generally stays within its banks from Woodinville down to the lake, so the main moisture source here isn't river flooding. Instead it's the climate: months of rain, ground that stays wet, and hillside lots in neighborhoods such as Arrowhead, Inglewood, Linwood Heights and Kenlake Vista where water can move toward a foundation from uphill. Lakeside lots near Log Boom Park and Saint Edward State Park sit in especially damp air. If framing or plumbing has to be replaced, check with City of Kenmore Development Services, whose team includes permit coordinators and building inspectors. The city's Code Compliance officer takes non-emergency concerns through its Report a Concern portal.

What to have ready

• A clear path to the hatch
• Notes on when the smell is strongest
• Any home inspection report that mentions the crawl space
• Questions about whether the vents, ground cover and gutters need work
