Black Mold Removal in Federal Way, WA

Calling about black mold in Federal Way

This page's number connects you with an independent local mold remediation company. The site itself is a referral service; it doesn't inspect or remove anything. On the first call, expect questions about where the growth is, whether it's on a hard surface or in drywall and carpet, whether you own or rent, and whether a leak has already been repaired. The company then arranges a visit, measures moisture around the growth, looks for hidden spread and writes a scope covering containment, removal, cleaning and drying.

Washington has no state mold license or certification, per DOH. Confirm the business is registered with Washington L&I as a construction contractor on L&I's Verify a Contractor tool, and compare written bids.

What moves the price

Angi's Seattle cost guide reports an average remediation job of about $1,988, typically $1,008 to $2,967. Specific spots differ a lot:

• Bathroom: $425 to $825
• Basement: $425 to $2,475
• Attic: $825 to $3,300
• Inside a wall: $825 to $16,550

Square footage, access, how much drywall or insulation comes out, and repairs afterward explain most of the range. The mold being black doesn't add to it.

Federal Way conditions

Federal Way sits between Seattle and Tacoma along I-5 and Pacific Highway, about 21 miles south of Seattle. The city's special flood hazard area lies mostly along its Puget Sound coastline, including coastal V and VE zones, and flood maps are kept on file at City Hall. Most homes are well away from the water, though, and the dark mold that turns up in them usually has everyday causes: a bathroom fan that's too weak, windows that sweat from fall to spring, or a slow leak in a wall shared with a kitchen or laundry. Homes near Steel Lake and Lake Killarney, or on lots where water drains toward the foundation, may also deal with damp lower floors.

Before the company comes

• Note when you first saw the growth and whether it's spreading
• Find out whether any leak nearby has been repaired
• Keep people with asthma away from the area
• Ask the Permit Center about permits if walls or plumbing will be rebuilt
