Mold & Mildew Cleanup in Burien, WA

What to look for

• Dark specks lining aluminum or wood window frames on the side of the house facing the water
• Mildew on bathroom ceilings and the top of shower walls
• A musty closet where coats or shoes pick up a smell
• Gray fuzz on furniture backs in a cold front room
• Stains spreading low on walls after storm surge or heavy rain reached the yard

Burien's moisture picture

Burien sits in the Highline area about 11 miles south of Seattle, with 5.5 miles of Puget Sound shoreline on its western edge. Most mildew here comes from the region's long, gray wet season: houses closed up from October to April, warm moist air inside and cool walls and glass that collect condensation. Homes close to the water often feel it most, because outdoor air stays humid and wind-driven rain finds gaps around older windows and doors.

Waterfront properties also face the Sound itself. FEMA flood maps set base flood elevations and flood depths for properties next to Puget Sound, and on Dec. 18, 2024 a +12.66-foot high tide combined with strong winds sent waves over waterfront properties and roads at Three Tree Point, leaving water and debris on SW 172nd Street. Where saltwater or storm runoff got inside, wet drywall, carpet and lower cabinets can grow mildew within days if they aren't dried.

Renters have a local resource. Burien's Rental Housing Inspection Program inspects apartments, duplexes, triplexes and four-plexes for health and safety every three years. Tenants first give the landlord written notice, and if the landlord doesn't respond they can contact City of Burien officials.

Cost

Angi's Seattle cost guide lists bathroom mold remediation at $425 to $825, with most pros charging $10 to $25 a square foot. Simple surface cleaning of tile and trim stays toward the bottom. Removing water-damaged drywall or carpet, cleaning several rooms, or repairs to electrical, plumbing or mechanical systems, which may need a Burien permit, push the total up.

What happens when you call

You'll reach an independent local mold remediation company; this site does no work itself. Tell them where the mildew is, how big it looks and whether water came in from outside. They should measure moisture, explain the cause and put the scope in writing. Check the company's L&I contractor registration on the Verify a Contractor tool before you sign.
