Mold & Mildew Cleanup in Kenmore, WA

What the call involves

This page connects you with an independent mold remediation company that covers Kenmore and the Northshore; the site itself doesn't clean or inspect. When you call, mention the rooms with mildew, how far it has spread and anything you have already tried. If it keeps returning after cleaning, say so, because that usually points to a ventilation gap or a hidden leak. The company should come out, look past the surface stain with a moisture meter, and leave you a written plan that lists what will be cleaned, what will be removed and what repairs you'll handle afterward.

Price drivers

Angi's Seattle cost guide puts bathroom mold remediation at $425 to $825, and HomeGuide's 2026 national bathroom range is $500 to $2,000. For a Kenmore home, the final number depends on:

• how much wall, ceiling or window area is affected
• whether paint and drywall clean up or have to be replaced
• work inside closets, cabinets or other tight spaces
• whether a better exhaust fan or duct is part of the fix
• patching and painting afterward

Kenmore conditions

Kenmore is a Northshore suburb about 10 miles northeast of Seattle at the top of Lake Washington, where the Sammamish River empties into the lake and Kenmore Air runs its seaplane service. King County says the Sammamish River from Woodinville downstream to the lake generally stays within its banks, so river flooding isn't the usual source here. Instead, homes in Arrowhead, Inglewood, Linwood Heights and Kenlake Vista deal with the region's long, gray wet season, wooded lots near Saint Edward State Park that stay shaded, and lake air that keeps humidity up. Windows stay cold for months and showers, cooking and laundry add moisture that settles on them. Ask Kenmore Development Services, which has permit coordinators and building inspectors on staff, whether drywall or fan work needs a permit.

Before anyone shows up

• Photograph the mildew in good light.
• Note whether it appears after showers, cold nights or rain.
• Empty the affected closet or cabinet.
• Check whether the bath fan vents outside or just into the attic.
• Write down any past roof, window or plumbing leaks.
