Mold Testing in Kingston, WA

What happens when you call

Calling the number on this page puts you in touch with an independent local company that offers mold inspection and testing. Be ready to describe the smell or staining, the rooms involved, and any leak or high-water event. Most good testers want to walk the house with a moisture meter before taking samples, because a lab result without a moisture finding leaves you without a next step. Ask how many samples they propose, where, and what each is supposed to answer. Ask also about the lab, the turnaround time, and whether the report explains results in plain language.

Cost factors

Angi's 2026 national data puts testing with both air and surface samples at $250 to $500, a basic air test at $250 to $350 and extensive testing at up to about $700. HomeGuide's 2026 national range for a surface sample is $50 to $200. What moves a Kingston bill:

• Number of rooms sampled, plus the outdoor control.
• Crawl space or attic access.
• Bulk samples cut from drywall or insulation.
• Rush lab turnaround.

Kingston conditions

Kingston is a North Kitsap ferry town on Appletree Cove, with a Washington State Ferries run to Edmonds and passenger service to Seattle. The waterfront is low-lying, about 7 feet in elevation, and Kitsap County's sea level rise assessment, a planning document rather than a rule, found modeled total water levels slightly above the shoreline's crest elevation. Homes near the cove can take moisture from high water and wind-driven rain, while houses on the hills behind town deal with crawl spaces, winter condensation and attic moisture. Kingston is unincorporated, so building permits come from the Kitsap County Department of Community Development. Renters should give the landlord written notice of leaks; Kitsap Public Health says landlords must fix building problems that let water in, though state law doesn't require them to do the mold remediation itself.

Before the tester arrives

• Don't clean or paint over suspect areas.
• Open access to the crawl space, attic and any storage under stairs.
• List when you first noticed the problem and any recent water events.
• Keep the house closed up beforehand if the tester asks.
