Conditions in Burien

Burien sits in the Highline area about 11 miles from Seattle, with 5.5 miles of Puget Sound shoreline along its western edge. FEMA flood maps set base flood elevations (Zone VE) and flood depths (Zone AO) for properties next to the Sound, and the city's Floodplain Administrator can help owners read them. On December 18, 2024, a 12.66-foot high tide combined with strong wind pushed waves over waterfront properties and roads at Three Tree Point, leaving water and debris on SW 172nd Street. Homeowners and renters policies don't cover flood damage, so review coverage before storm season.

Inland, Olde Burien and the neighborhoods off Ambaum Boulevard deal with the regional mix: months of rain, slow drying and condensation on cold surfaces. Poorly ventilated attics and crawl spaces are frequent trouble spots.

Renters have a defined path. Burien's Rental Housing Inspection Program inspects apartments, duplexes, triplexes and four-plexes every three years, and tenants who give the landlord written notice under RCW 59.18.070 can contact city officials if nothing happens.

Cost drivers

Angi's Seattle cost guide puts the average around $1,988, with pros charging about $10 to $25 per square foot. Shoreline homes may need more material removed if water got into wall cavities, and tight access under older houses adds labor. Ask whether the bid includes replacement drywall, which Angi lists separately at $825 to $2,400.

What to expect on the call

You'll be connected with an independent local company that asks about the location, size and cause of the problem, then schedules a look. Get the scope in writing, confirm the company's Washington L&I contractor registration on the Verify tool, and ask how they will show the area is dry before closing up walls. If electrical, plumbing or mechanical systems need repair afterward, a City of Burien permit may apply; the city takes permit questions at its main line.
