Mold Inspection in Medina, WA

Medina in brief

Medina sits about 4 miles from Seattle across the SR 520 Evergreen Point Floating Bridge, bordered by Clyde Hill and Hunts Point, with Lake Washington on every side except the east. Its Shoreline Master Program also covers creeks, streams and wetlands within the city. Near the water, large windows, lower floors set into the slope and heavy landscaping can all keep moisture around through a wet winter.

What to do now

1. Find and stop any active water: a dripping fixture, irrigation spraying the siding or a clogged roof drain.
2. Leave visible growth alone. Cleaning it first removes the evidence an inspector needs to judge the extent.
3. Keep the heat on and the bath and kitchen fans running to slow new condensation.
4. If a housekeeper or property manager noticed the problem, ask what they saw and when.
5. Collect plans or remodel records so the inspector knows where plumbing and ducts run.

What affects cost

Angi's 2026 national data puts a mold inspection at $303 to $1,044, and HomeGuide says large homes with widespread mold can reach about $1,000. In Medina, larger floor plans, several mechanical rooms and hard-to-reach crawl spaces push quotes up, as does any lab sampling. EPA says sampling is usually unnecessary when mold is visible. Rebuilding after cleanup goes through the City of Medina Development Services Department, whose director serves as the city's Building Official.

When you call, you're connected with an independent local inspector or remediation company. Washington has no state mold certification, so ask about training and experience, ask for a sample report, and if a separate company will do any removal, check its contractor registration on L&I's Verify a Contractor tool before signing anything.
