Mold & Mildew Cleanup in Stanwood, WA

Signs to watch for

• Black or gray specks along window frames and sills.
• A musty smell in lower rooms after a high-water event, even if water never seemed to come in.
• Peeling paint or spotting above a shower.
• Mildew on stored boxes, furniture backs or clothing.
• Swollen baseboards or a faint line on lower walls.

Why it grows here

Stanwood sits on the floodplain near the mouth of the Stillaguamish River, about 41 miles from Seattle, where the river meets the tidal estuaries of Skagit Bay. Century-old dikes protect about 2,200 acres of farmland, and Highway 532 acts as a levee for downtown. Flooding has been part of the town's history: in 1910 floodwater covered the floors of nearly every house, in 1951 dikes failed at Stanwood and East Stanwood, and in 1990 Leque Road residents evacuated. In January 2009 people were rescued from four to five feet of water on Marine Drive and Thomle Road just south of the city, and in December 2023 the river set a record crest upstream at Arlington while Stanwood's dikes held. When the river rises above Irvine Slough, stormwater backs up and downtown can flood, and the city keeps a deployable floodwall on Marine Drive. Beyond floods, the long wet season brings the usual condensation mildew to windows and bathrooms.

What cleanup costs

Angi's Seattle cost guide lists bathroom mold remediation at $425 to $825 and a typical job at about $1,008 to $2,967. Surface cleaning costs least; removing wet drywall, insulation and flooring after high water costs much more, and repairs come on top. If a floodplain structure is damaged or improved by more than 50 percent of its market value, Stanwood requires it to be elevated to the designated floodplain elevation, which can change the whole rebuild plan.
