Mold Removal in Lake Stevens, WA

Lake, creek and wetland

Lake Stevens is a commuter city in Snohomish County about 6 miles east of Everett and roughly 30 miles from Seattle, with downtown on the lake's northeastern arm. The lake drains through Catherine Creek to the Pilchuck River. The city's own environment element says areas prone to 100-year floods are limited mostly to properties fronting Catherine Creek and the lake, mapped as Zone A on FEMA flood maps. It also notes flooding when wetlands, streams and ditches overflow, which can put water against foundations in neighborhoods nowhere near the shoreline.

That pattern matters for mold. A lakefront home can get high groundwater under the crawl space every winter. A house near a wetland edge in Machias or along 20th Street SE can see water pooling against the foundation after a run of storms. Either way, framing and subfloors stay damp long enough for growth.

Signs to look for

• Musty smell that gets stronger when the furnace runs, which can mean the crawl space air is being pulled into the house.
• White or dark fuzz on floor joists, or water beading on the crawl space plastic.
• Peeling paint and stains on the lower parts of basement walls.
• Black spotting along window sills and in closets on north-facing walls.

Permits and complaints

The City of Lake Stevens Building Division, in Planning & Community Development, handles plan review and inspections, with permits through the Online Permit Center. Flood hazard areas are regulated under the city's municipal code and Critical Areas Ordinance, so rebuilding on a lakefront or creekside lot after water damage is worth discussing with the city first. Mold cleanup on its own is not described as permitted work.

Lake Stevens Code Enforcement, reached through the Code Enforcement Portal, covers nuisance, land use and stormwater code; housing conditions are not on its list. Renters with an unrepaired leak should notify the landlord in writing as Washington's landlord-tenant law describes. The Snohomish County Health Department does not investigate mold complaints in private homes or test mold, and it points landlord mold disputes to the Dispute Resolution Center of Snohomish and Island Counties.

What a call gets you

You are connected with an independent local company that can inspect, find the water source and quote the work. Washington has no state mold license or certification, according to the Department of Health; check construction contractor registration on L&I's Verify a Contractor tool. If you want air or surface sampling after the work, Angi suggests using a different company from the one that did the removal.
