Mildew in Lynnwood apartments and houses usually grows where winter condensation collects: window frames, bathroom ceilings and closets on outside walls. Renters and owners can usually clean small patches on hard surfaces, but growth over about 10 square feet, soft drywall or mildew tied to a leak needs a professional. Call the number on this page to be connected with a local mold remediation company in Lynnwood.

Lynnwood at a glance
Lynnwood sits at the junction of I-5 and I-405, about 15 miles north of Seattle, with a dense core around Alderwood Mall and the City Center station. A community profile estimates more renter-occupied households than owner-occupied ones. Most of the city drains to Swamp Creek or through Lund's Gulch to Puget Sound, with Scriber Creek, Scriber Lake and Hall Lake inside city limits.
What to do now
- Photograph it. Date-stamped pictures help with a landlord, an insurer or a company quote.
- Check the size. Under about 10 square feet on hard surfaces is a reasonable cleanup job, per EPA and Washington DOH.
- Clean and dry. Detergent and water, gloves and eye protection, then dry the surface fully.
- Report building problems in writing. Renters should tell the landlord about leaks, broken fans or windows that let water in. Landlords must keep units reasonably weathertight and give tenants DOH-approved mold information.
- Cut indoor moisture. Run fans, keep some heat on, and avoid drying laundry in closed rooms.

Signs and likely causes
| What you see | Likely cause |
|---|---|
| Water pooling on sills each morning, black specks on the frame | Indoor humidity too high for cold or aging windows |
| Ceiling mildew over the shower | No fan, a broken one, or one switched off too soon |
| Growth low on a wall shared with a neighbor's bathroom | A plumbing leak inside the wall |
| Mildew on the inside of closet doors and stored bags | Cold exterior wall and no air movement |
Cost factors
Angi's Seattle cost guide puts bathroom mold remediation at $425 to $825 and most work at $10 to $25 per square foot. Cost rises with the size of the area, how much drywall or trim comes out and whether occupied rooms need containment. A quick wipe-down of a window frame costs far less than opening a wall behind a leaking shower, so an honest description on the phone helps a company give a realistic range. Repairs that need permits go through Lynnwood Development & Business Services. For homes in severe disrepair, Lynnwood Code Enforcement takes reports; properties outside city limits go to Snohomish County Code Enforcement.
