Ravensdale is a small rural community east of Maple Valley in unincorporated King County, and mold remediation here usually follows the same wet-climate problems as the rest of the region: roof leaks, damp crawl spaces and condensation in closed-up rooms. A remediation company contains the area, removes growth and damaged materials, and dries the structure. Call the number on this page to be connected with a local mold remediation company in Ravensdale.

About Ravensdale
Ravensdale is a former coal-mining community about 24 miles from Seattle, reached by Kent Kangley Road, Landsburg Road and SR 169. It incorporated in 1913 and disincorporated in the 1920s, so King County handles building permits and code enforcement. On rural properties, mold problems often start in the places that get checked least: crawl spaces, attics, detached garages and shops. The region's long wet season means anything that gets wet dries slowly without help.
What to do now
- Find the source. Look for roof leaks, clogged gutters, plumbing drips and water pooling against the foundation.
- Dry it fast. DOH and EPA both say to dry wet materials within 24 to 48 hours.
- Size it up. About 10 square feet is the dividing line between a homeowner cleanup and a professional job.
- Don't cover it. EPA says never to paint or caulk over mold.
- Know who handles permits. King County Permits covers building permits for unincorporated areas including Ravensdale, so contact the county before replacing walls or framing.

Signs and their usual causes
| What you see | Likely cause |
|---|---|
| Musty smell when the furnace runs | Damp crawl space or contaminated ductwork |
| White fuzz on crawl space joists | High humidity under the house, or a missing or torn vapor barrier |
| Stained ceiling drywall | Roof or flashing leak |
| Black spots on bedroom walls behind furniture | Condensation on cold walls with little air movement |
| Mold on stored items in a shop or garage | Damp air and no heat |
Cost factors
Angi's Seattle cost guide gives the closest regional reference: an average of $1,988, labor at $75 to $120 an hour, and crawl spaces at $425 to $1,650. Rural jobs may add travel and access time. Price also depends on how much material comes out and whether rebuild is included. Check any company's registration on L&I's Verify a Contractor tool, since Washington has no mold license. Renters should know King County Code Enforcement takes substandard-housing complaints in unincorporated areas but won't settle tenant-landlord disputes, so start with written notice to the landlord. For health questions, Public Health - Seattle & King County offers indoor air quality and mold consultations.
