Commercial Mold Remediation in Ravensdale, WA

Ravensdale background

Ravensdale is a former coal-mining community of about 555 people along Kent Kangley Road, Landsburg Road and SR 169, roughly 24 miles from Seattle. It was incorporated in 1913 and gave up its city status in the 1920s, so King County now handles permits and code enforcement. Rural foothill properties here deal with heavy winter rain, tall trees that drop needles into gutters, wells and outbuildings, and buildings that may sit closed for long stretches.

What to do first

1. Track down the source: roof, gutter, plumbing, a wet crawl space or water running toward the building.
2. Close off the room and keep tenants, workers or volunteers out of it.
3. Turn off any forced-air system that pulls from the affected area.
4. Don't sand, power-wash or bleach the growth; that spreads spores and hides the extent.
5. Notify tenants in writing if it is a rental.
6. Take photos for the insurance carrier.
7. If the building serves the public, such as a church or shop, post a notice that the area is closed until the work is finished.

What affects cost

Small rural commercial jobs are priced like the larger residential ones they resemble. Angi's Seattle cost guide lists crawl spaces at $425 to $1,650 and attics at $825 to $3,300, as residential reference points. Travel distance, crawl space height, how much insulation or drywall comes out and whether rebuild is included all change the bid. Rebuilding that needs a permit goes through King County Permits, which covers unincorporated areas including Ravensdale. The King County Code Enforcement Section takes substandard housing complaints but does not handle tenant-landlord disputes. Washington has no mold license, so check the remediation company's Washington L&I contractor registration on the Verify a Contractor tool before work begins, and get the scope and price in writing.
