Lynnwood has more renter households than owner households and a dense retail core around Alderwood Mall, so much of its mold work is commercial: apartment complexes, stores and offices with people inside. Remediation there is about stopping the moisture, sealing the work area and removing growth without disrupting the rest of the building.

Lynnwood buildings and moisture
Lynnwood sits at the junction of I-5 and I-405, about 15 miles north of Seattle, with Alderwood Mall and a major transit center at its core. A community profile estimates more renter-occupied than owner-occupied households, roughly 9,186 to 8,164, which puts a large share of the city's living space in multifamily buildings. The city drains mostly to Swamp Creek or to Puget Sound through Lund's Gulch, and Scriber Creek, Scriber Lake and Hall Lake lie within city limits. In apartment complexes, the usual mold sources are leaks between units, bath fans that don't move enough air, and winter condensation on windows and exterior walls.
What to do now
- Stop the source. Shut off a leaking line, repair the roof or window, or fix the exhaust fan before anything else.
- Check neighboring units. Water travels. Look at the unit below and beside the affected one, and inside shared chases.
- Notify residents or staff in writing. Say which areas are closed and for how long.
- Shut down shared air serving the area if contamination is suspected, as EPA advises.
- Get a written scope from a company registered with Washington L&I, and check registration on the Verify a Contractor tool.
Signs and their usual causes
| What you see | Likely cause |
|---|---|
| Growth on a ceiling under an upstairs bathroom | A leaking tub, toilet seal or supply line in the unit above |
| Black spotting on window sills in several units | Winter condensation with too little ventilation |
| Musty smell in a ground-floor storeroom | Water at grade or a damp slab |
| Bubbling paint along a corridor wall | A plumbing leak inside the wall |
| Stained tiles in a retail ceiling | Roof drain or rooftop unit leak |
Cost factors
Each commercial job is priced on its own. Angi's Seattle cost guide lists $10 to $25 per square foot for home jobs, a reference point only. Bids grow with the number of units involved, relocation or phasing needs, ceiling height, duct cleaning and the amount of drywall and paint afterward. Permits for repairs go through Lynnwood Development & Business Services. Tenants with unfixed leaks can report homes in severe disrepair to Lynnwood Code Enforcement, and the Snohomish County Health Department notes that the state landlord-tenant act requires landlords to inform tenants about mold.
