Ravensdale's setting
Ravensdale is a small rural community in unincorporated King County, east of Maple Valley and about 24 miles southeast of Seattle, along Kent Kangley Road and near Landsburg. It began as a coal-mining town and is still small and rural. Where trees shade a house, the region's gray months from October to April leave walls, roofs and windows little chance to dry fully. Rooms that are heated unevenly, or closed off in winter, are where mildew usually takes hold.
What to do first
- Track the moisture. Look for condensation on windows, a bath fan that isn't venting outdoors, a roof or plumbing leak, or water pooling near the foundation.
- Size it up. If it's under about 10 square feet on hard surfaces, EPA says most homeowners can handle it.
- Scrub with detergent and water, then dry the surface well. Gloves and eye protection help.
- Toss moldy porous items you can't clean, such as old cardboard boxes or ceiling tiles.
- Keep heat on in every room and move furniture a few inches off outside walls.
- Use a dehumidifier in rooms that stay damp, aiming for humidity under 60 percent.
Reading the signs
| You notice | Often caused by |
|---|---|
| Morning water and black spots on window glass | Warm, moist indoor air on cold panes |
| Mildew on the ceiling near an exterior corner | A cold spot from missing insulation or a roof leak |
| Bloom on items in a spare room | A closed, unheated room |
| Mustiness in a lower room after storms | Runoff collecting at the foundation |
| Spots around the bathroom fan grille | A fan that is too weak or vents into the attic |
Cost factors
Angi's Seattle cost guide lists bathroom mold remediation at $425 to $825 and says most pros charge $10 to $25 a square foot. Travel to a rural property, the size of the affected area, how much drywall or insulation must be replaced and any repairs to the moisture source all shape the price. Because Ravensdale is unincorporated, building permits for repair work come from King County Permits, and King County Code Enforcement takes complaints about substandard housing.
