Black Mold Removal in Tukwila, WA

I rent in Tukwila. Who do I contact about black mold?

Start with the landlord, in writing. Census figures put Tukwila's owner-occupied rate at 40.4 percent, so most households rent. Washington DOH tells tenants to report leaks and moisture buildup promptly in writing, and landlords are responsible for fixing building problems such as leaks or broken ventilation. Under the Residential Landlord-Tenant Act, landlords must also give tenants DOH-approved mold information. Tukwila rentals need an annual license and a unit inspection before first occupancy and every four years, and tenants with concerns about living conditions can ask the Rental Housing Licensing Program, run through the Permit Center, for a courtesy City inspection. The program's page also links mold resources for tenants and owners. This is general information, not legal advice.

Did the Green River levee breach affect homes?

On December 15, 2025, during repeated atmospheric river storms, the Desimone Levee on the Green River in Tukwila breached. The GO NOW evacuation covered the part of the city south of S 180th Street and west of West Valley Highway, which is mostly industrial and business property. Any building that took on water and couldn't be dried within 24 to 48 hours should be treated as moldy, per EPA. King County flood services runs flood warnings for the Green-Duwamish and publishes floodplain maps.

How do I choose a company for the removal?

Washington has no state mold license, so the basic check is registration with Washington L&I as a construction contractor, which you can confirm on L&I's Verify tool. Get written bids that list containment, what material comes out, drying and repairs. Angi's Seattle cost guide reports a typical job at $1,008 to $2,967 and a bathroom at $425 to $825. Ask how the company will show the area is clean when it's done; an independent check is good practice.

One more Tukwila note

If repairs after removal need a building permit, the Tukwila Permit Center at 6300 Southcenter Blvd. handles construction permits. Before walls go back up, ask for moisture readings showing the framing is dry. Renters shouldn't tear out moldy drywall themselves; it's the landlord's repair, and disturbing a large patch can spread spores through the unit.
