Lynnwood has more renter households than owner households, so much of the mold here turns up in apartments and rented homes, usually from condensation, plumbing leaks or roof and window problems. Owners of older houses near Scriber Creek, Swamp Creek and Hall Lake see damp crawl spaces too. Call the number on this page to be connected with a local mold remediation company in Lynnwood.

A renter city at the I-5 and I-405 junction
Lynnwood sits where I-5 meets I-405, about 15 miles north of Seattle in southwest Snohomish County. It is often described as a bedroom community, with a dense retail core around Alderwood Mall and the Lynnwood City Center transit station. A community profile based on Esri estimates counts about 9,186 renter households against 8,164 owner households.
In apartment buildings, mold usually starts small: a shower with no working fan, a dryer vent that leaks into a closet, a supply line dripping inside a vanity, or a bedroom where windows run with condensation every winter morning. Upstairs leaks travel down through ceilings into units below, and tenants often see the stain before the building owner knows there is a problem.
What renters can do
- Report the leak or moisture to the landlord or manager in writing, and keep a copy with photos.
- Keep heat on, run fans and wipe condensation daily; Washington DOH says tenants should limit condensation while landlords fix building problems that cause moisture.
- If repairs don't start, Lynnwood Code Enforcement in Development & Business Services takes reports of problems such as homes in severe disrepair. Properties outside city limits go to Snohomish County Code Enforcement.
Washington law requires landlords to keep units weathertight and to give tenants Department of Health information about mold, and it sets time frames for starting repairs after written notice. This is general information, not legal advice.
Creeks and lakes in town
Most of Lynnwood drains to Swamp Creek or to Puget Sound through Lund's Gulch. Scriber Creek, Scriber Lake and Hall Lake are inside the city. Houses on low ground near those waters, or below a slope in Meadowdale, can see seepage into crawl spaces and basements during long wet spells. Snohomish County's Flood Information Center has a real-time flood map if you want to check conditions near you.
Permits, health and hiring
City of Lynnwood Development & Business Services reviews building plans and issues permits; check with it before rebuilding walls or floors after removal. The cleanup itself is not described as permitted work. The Snohomish County Health Department does not investigate mold in private residences or test mold, and it refers landlord disputes to the Volunteers of America Dispute Resolution Center of Snohomish and Island Counties.
The company you are connected with is independent. Washington has no state mold license; confirm construction contractor registration on L&I's Verify a Contractor tool before work begins.
