Black Mold Removal in Marysville, WA

How the call works

Tell us what the growth looks like, which room it's in, and whether there's been a leak or high water. You'll be put through to an independent local company that covers Marysville. The company arranges its own visit and should:

1. Find the moisture source and confirm it's stopped or can be fixed.
2. Measure how much material is affected, including behind walls and under floors.
3. Recommend containment, removal and cleaning steps in writing.
4. Explain how the area will be dried and how you'll know the job is done.

Washington has no state mold license, according to DOH, so ask whether the company is registered with Washington L&I as a construction contractor and check it on L&I's Verify tool.

Cost drivers

Angi's Seattle cost guide, the closest published local benchmark, puts a typical job at $1,008 to $2,967 and a basement at $425 to $2,475. Most pros charge $10 to $25 per square foot. Expect more when floodwater soaked lower walls, when insulation and carpet must go, or when repairs follow. Related repairs in the same guide run $825 to $2,400 for drywall and $650 to $2,150 for carpet.

Local conditions

Marysville sits about 32 miles north of Seattle on the north side of the Snohomish River delta, with Ebey Slough forming its southern boundary and Quilceda Creek and Allen Creek draining the city. Snohomish County's Flood Information Center runs a real-time flood map, river gauge alerts and a Flood Recovery Guide for residents near the slough and the delta. Away from the water, in Sunnyside, Cedarcrest and Smokey Point, black growth usually follows the wet season indoors: cold window frames, unvented bathrooms, and crawl spaces that never dry out.

Permits for rebuilding after removal go through Marysville Building Services in the Community Development Department. The city's Code Enforcement Unit, part of the police department, handles public nuisance, dangerous buildings and non-maintained structures.

Checklist before the visit

• Shut off or fix the leak if you safely can.
• Photograph the growth and any water damage.
• Turn off a furnace you suspect is contaminated.
• Keep children and anyone with asthma away from the area.
