Lynnwood has more renter households than owner households, so mold questions here often involve a landlord as well as a remediation company. Either way, the work means stopping the moisture and removing growth inside a contained area. Call the number on this page to be connected with a local mold remediation company in Lynnwood.

The Lynnwood picture
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 transit center. A community profile estimates about 9,186 renter households to 8,164 owner households. The city drains mostly to Swamp Creek or through Lund's Gulch to Puget Sound, with Scriber Creek, Scriber Lake and Hall Lake inside city limits. In apartments and condos, the common sources are shared: a neighbor's leak through the ceiling, bathroom fans that do not pull enough air, and condensation on windows in units kept closed all winter.
What to do now
- Find the source. Look up, behind and below the growth. In multi-unit buildings, the water may come from another unit.
- Tell the right person. Renters should notify the landlord or manager in writing; condo owners should alert the association if a common pipe or roof is involved.
- Check the size. Under about 10 square feet on a hard surface, EPA says it is usually manageable without a professional. Larger patches or hidden growth call for one.
- Hold off on bleach and paint. Neither fixes growth rooted in drywall or carpet, and paint over mold just hides it.
- Keep sensitive people away. EPA says people with asthma or weakened immune systems should avoid moldy areas.

What the signs usually mean
| What you see | Likely cause |
|---|---|
| Brown ring on the ceiling of a lower-floor unit | Leak from the unit or roof above |
| Black spotting on window sills and blinds | Winter condensation with little ventilation |
| Mold on the bathroom ceiling and grout | An undersized or unused exhaust fan |
| Musty carpet near a sliding door | Water getting past the door track or flashing |
| Growth inside a closet on an outside wall | Cold wall surface and trapped humid air |
Cost factors
Angi's Seattle cost guide reports most jobs at $1,008 to $2,967 and bathrooms at $425 to $825. Multi-unit jobs can cost more when walls shared with neighbors must be opened or when several units need containment. Drywall replacement adds $825 to $2,400 in that guide. Any rebuild that needs permits goes through Lynnwood's Development & Business Services department. Before signing, confirm the company's registration with L&I as a construction contractor.
