Mold Inspection in Stanwood, WA

Signs it's time for an inspection

• A musty smell in the crawl space or ground floor after the Stillaguamish runs high.
• Water stains or swollen baseboards near the floor.
• Insulation under the house that's wet or hanging down.
• Mildew that keeps returning on walls or ceilings.
• Any home that took floodwater and wasn't fully dried within 24 to 48 hours.

Local conditions in Stanwood

Stanwood sits on the floodplain near the mouth of the Stillaguamish River, where it meets the tidal estuaries of Skagit Bay, about 41 miles north of Seattle. Century-old dikes protect roughly 2,200 acres of farmland, and Highway 532 acts as a levee for downtown. Flooding has shaped the town for generations: in 1910 water covered the floors of nearly every house, dikes failed at Stanwood and East Stanwood in 1951, and Leque Road residents evacuated in 1990. In January 2009, boats and hovercraft rescued people on Marine Drive and Thomle Road just south of town, and in December 2023 the river set a record crest upstream at Arlington while the dikes west of town held. When the river rises above Irvine Slough, stormwater backs up and downtown can flood, which is why the city keeps a deployable floodwall on Marine Drive.

What affects the cost

National 2026 data from Angi puts inspections at $303 to $1,044, and HomeGuide lists $300 to $650. In Stanwood the price follows the size of the house, crawl space height, how many walls took water and whether lab samples are needed. After a flood, an inspector may need readings in every affected room, which takes longer.

What happens when you call

Your call goes to an independent local inspection company serving Stanwood. Share whether the house flooded, how high the water reached and what has been removed already. The inspector checks the crawl space, lower walls, flooring and attic, then writes up the findings with photos. If the report points to major repairs, talk with the City of Stanwood Community Development Department first: a floodplain structure damaged or improved by more than 50 percent of its market value must be elevated to the designated floodplain elevation, and filling, grading or new construction in the Municipal Floodplain needs a Floodplain Development Permit.
