Kingston crawl space mold usually means the space under the house sits over wet soil or takes in water from rain, runoff or the low shoreline. A remediation company will clean or treat the framing, remove soaked insulation and plan around the water source. Call the number on this page to be connected with a local mold remediation company in Kingston.

What happens when you call
Calling the number on this page puts you in touch with an independent local company that handles crawl space mold in North Kitsap. Expect a short conversation about what you have found, when the smell or dampness started, and any history of leaks or water under the house. At the visit, the inspector or technician should go into the space, take moisture readings in joists and sill plates, look at the vents, ground cover and any ductwork, and photograph the problem areas. A good written scope names where the water comes from and lists each part of the work: framing cleanup, insulation removal, ground cover, and drainage or vent changes.
Cost factors
- Crawl space size and clearance.
- Extent of growth on joists, beams and subfloor.
- Amount of wet insulation to remove and replace.
- Ground cover, dehumidification or drainage work added to the scope.
- Rot repairs that require a county building permit.
Angi's Seattle cost guide lists crawl space jobs at $425 to $1,650. HomeGuide's 2026 national range is $1,500 to $4,000.

Kingston conditions
Kingston is the North Kitsap ferry town on Appletree Cove, with Washington State Ferries service to Edmonds and passenger service to Seattle. Its waterfront is low, around 7 feet above sea level. Kitsap County's sea level rise risk assessment, a planning study, found modeled total water levels slightly above Kingston's shoreline crest elevation. For homes near the cove, that means storm water or high tides can come close to foundations; for homes up the hill along State Route 104, rain moving through the soil is the more common source. Kingston is unincorporated, so building permits, including post-storm repair permits, come from Kitsap County DCD Permit Services.
Checklist before the visit
- Clear stored items away from the crawl space hatch.
- Note when you smell it most, and whether it follows heavy rain or high tides.
- Find past plumbing or roofing invoices.
- Check the company on L&I's Verify a Contractor tool; Washington has no state mold license.
- Ask whether the bid separates mold cleanup from ground cover and drainage.
- Decide who will let the crew in if you commute on the ferry during the day.
For renters, Kitsap Public Health says landlords must fix building problems that let water in and that leaks should be reported in writing.
