Stop the water, then remove what's moldy. Call the number on this page to be connected with a local mold remediation company in Kirkland.

Kirkland's neighborhoods
Kirkland lies on the east side of Lake Washington, about 8 miles from Seattle. Downtown sits along Moss Bay, with Juanita Bay and Juanita Beach Park to the north. Inland, Totem Lake, Houghton, Rose Hill, Finn Hill and Kingsgate spread out along I-405. The median house in the city was built in 1980, so plenty of homes are well into their fifth decade.
Rain more than the lake
The City of Kirkland says flooding here is most likely from heavy rainfall or other situations that overwhelm the drainage system, not from the lake itself. Flood damage is rarely covered by homeowners or renters policies, the city notes, and it points residents to the National Flood Insurance Program and to King County's floodplain maps to check whether a property is in a 100-year floodplain.
For a house built around 1980, the weak points are predictable. Here is what to check, and when:
| Where | What to look for | Best time to check |
|---|---|---|
| Attic | Dark sheathing near bath fan ducts, frost on nails | Cold mornings in winter |
| Crawl space | Standing water, sagging insulation, musty smell | After a few days of heavy rain |
| Windows | Spotting on sills and frames, peeling paint below | Early morning, October to April |
| Lower level | Damp carpet edges, staining at the base of walls | During and after storms |
EPA's two rules apply everywhere: fix the water problem or mold will return, and don't paint or caulk over growth.
City offices
Kirkland's Development Services Center is the shared front desk for development permits across Planning and Building, Public Works and Fire. Ask there before rebuilding drywall, framing or a finished basement after removal.
The Planning and Building Department runs the Code Enforcement Program, which takes complaints online or by phone and covers dangerous buildings or structures. Its page doesn't mention rentals or mold, so renters should start with written notice to the landlord about the leak or moisture; Washington law then gives the landlord set times to start repairs.
Public Health - Seattle & King County's environmental health specialists consult on indoor air quality and mold questions.
When you call
You'll be connected with an independent local mold remediation company. Washington has no state mold license or certification. Check L&I contractor registration on the Verify a Contractor tool, and ask for an itemized written scope. L&I also suggests paying as phases are finished rather than all up front, and getting any change to the plan in writing. If the same company offers to test and remove, consider an independent check at the end.
