Mold Inspection in Federal Way, WA

What happens when you call

You'll be put in touch with an independent local mold inspector or remediation company. A short description of the problem helps them plan the visit: where you see or smell it, how long it's been going on, and whether there was a leak. At the house, expect a room-by-room walk-through, moisture readings at exterior walls, windows, bathrooms and the kitchen, and checks of the attic and any crawl space. Good inspectors explain what they find as they go and put it in writing afterward.

Cost factors

HomeGuide's 2026 national range for a mold inspection is $300 to $650, averaging about $450, with a $200 minimum at the low end. Angi's 2026 national figures for testing, if you choose it, run $250 to $350 for a basic air test and $200 to $300 for a surface or swab test. What pushes a Federal Way quote up:

• A larger home, townhouse block or multiple units.
• Tight or wet crawl spaces and attics without easy hatches.
• Sampling several rooms instead of one.

Local conditions

Federal Way sits along I-5 and Pacific Highway between Seattle and Tacoma, about 21 miles from downtown Seattle, and was incorporated in 1990. Water nearby includes Steel Lake, Lake Killarney and the shoreline at Dash Point State Park. The city regulates special flood hazard areas under its flood damage prevention code and says most of that area lies along its Puget Sound coastline, with flood maps kept on file at City Hall. For most homes inland, though, the moisture is local: winter condensation, bath fans that vent into the attic, gutters overflowing against siding, and plumbing leaks.

If repairs follow, the Federal Way Permit Center answers building permit questions; note that it is closed to the public on Wednesdays. Renters with an unrepaired leak can contact the city's Code Compliance office, which enforces building codes and the International Property Maintenance Code, after giving the landlord written notice.

Short checklist before the company arrives

• Don't clean or paint the stained area.
• Make the attic and crawl space reachable.
• List leaks or repairs from the past few years.
• Write down your questions about the report.
