Black mold in a Ravensdale home usually points to a roof leak, plumbing drip, condensation or a damp crawl space that has kept materials wet for a while. Removal means fixing that moisture, then cleaning hard surfaces and replacing porous materials that are stained through. Call the number on this page to be connected with a local mold remediation company in Ravensdale.
Ravensdale is a small, unincorporated former coal-mining community of about 555 people in southeast King County, east of Maple Valley near Landsburg and about 24 miles from Seattle. With no city government, King County handles building permits and code enforcement here. Rural houses here deal with the wet months from fall to spring, when roofs, gutters and crawl spaces take a beating and surfaces stay cool and damp.
What to do now
- Trace the moisture. Look above the growth for roof or flashing leaks and below it for plumbing and crawl space dampness.
- Fix or stop the source. Clear gutters and downspouts, shut a leaking valve, or tarp a roof until it can be repaired.
- Size it up. A patch under about 10 square feet is usually a homeowner job, per EPA and DOH; larger or hidden growth needs a professional.
- Clean small spots properly. Gloves, eye protection, detergent and water, then dry the surface completely.
- Don't cover it. EPA says painting or caulking over mold doesn't work.
- Watch the furnace. If ducts run through a moldy crawl space or attic, ask before running the system.
What you see and the usual cause
| What you see | Likely cause |
|---|---|
| Dark ring on a ceiling, especially near a chimney or vent pipe | Flashing leak during heavy rain |
| Black growth along the floor of a closet or back bedroom | Cold exterior wall and damp crawl space below |
| Mold on window sills every winter | Condensation from indoor moisture |
| Spots in a room over the garage or an addition | Thin insulation or poor ventilation in the newer part of the house |
| Damp, musty smell in the whole house | Crawl space moisture rising into the living space |
Cost factors
Angi's Seattle cost guide reports a typical remediation job at $1,008 to $2,967 and crawl space work at $425 to $1,650. Rural homes can cost more to reach and to set up containment in, and the amount of drywall, insulation or subfloor removed matters most. Repairs that rebuild walls or framing go through King County Permits. Confirm the company is registered with Washington L&I as a construction contractor on L&I's Verify tool, since the state has no mold license.
