Mold Removal & Remediation in Tukwila, WA

I rent in Tukwila. Who deals with the mold?

Census figures put Tukwila's owner-occupied rate at about 40 percent, so most homes here are rentals. Under Washington's landlord-tenant law, landlords must keep units reasonably weathertight and give tenants Department of Health-approved information on mold. If moisture is the problem, a leak, a broken bath fan or water coming through a window, tell the landlord in writing; the law then gives the landlord set time frames to start repairs. Tukwila requires an annual rental license, with each unit inspected before first occupancy and every four years, and tenants with concerns about living conditions can ask the Rental Housing Licensing Program for a courtesy City inspection. The program's page also links tenants and owners to mold cleanup resources. This is general information, not legal advice.

Did the Green River levee breach mean mold for nearby buildings?

On December 15, 2025, during repeated atmospheric river storms, the Desimone Levee on the Green River in Tukwila breached. A GO NOW evacuation covered the part of the city south of S 180th Street and west of West Valley Highway, a mostly industrial and business area. Any building that took water and could not be dried within 24 to 48 hours should be treated as having mold, according to EPA guidance. For warehouses and offices, EPA's commercial remediation document describes containment and cleanup for larger areas, and the work usually needs a company that handles commercial jobs.

What will it cost?

Angi's Seattle cost guide reports an average of $1,988, with most jobs between $1,008 and $2,967. Bathrooms, a frequent trouble spot in apartments, run $425 to $825 in that guide, and wall cavities range from $825 to $16,550 depending on how far the growth spreads. Labor is listed at $75 to $120 an hour. Add drywall, paint and flooring if they are part of the scope. Washington has no state mold license, so confirm the company is registered with L&I as a construction contractor on L&I's Verify a Contractor tool before you sign.

After the removal

When rebuild involves new walls, framing or other construction, the City of Tukwila Permit Center on Southcenter Boulevard issues construction permits, including building permits. Ask the remediation company whether its quote stops at removal or carries through to rebuild.
