Most mildew in Allyn homes is surface mold on windows, bathrooms and closets, fed by winter condensation and rooms that stay closed. Small patches on hard surfaces can usually be cleaned by the homeowner, and larger or recurring growth should go to a professional who also finds the moisture source.

Allyn at a glance
Allyn is a small unincorporated community on the western shore of North Bay, at the head of Case Inlet in Mason County. Most residents live in Lakeland Village, a planned development of more than 800 homes built around a golf course and the private Lake Anderson. Houses near the bay or the lake pick up moist air, and every house deals with the region's long, gray winter. Mildew follows the moisture to the coldest, least-ventilated spots: window corners, bathroom ceilings, the back walls of closets and rooms that are shut off to save on heating. A house left closed for weeks gives it even more time.
What to do first
- Note where the growth is and estimate the area. Under about 10 square feet on a hard surface is the range EPA considers a homeowner job.
- Clean with detergent and water, wearing gloves and eye protection, then dry completely.
- Skip the paintbrush. EPA advises against painting or caulking over mold.
- Set a dehumidifier or run fans in rooms that stay damp, aiming for indoor humidity under 60 percent.
- Inspect windows, the roof line and plumbing near the growth for leaks.
- Call a company if the area is large, returns, or the drywall underneath is soft.
Signs and what's usually behind them
| What you see | Likely cause |
|---|---|
| Black corners on window frames | Condensation from warm indoor air on cold glass |
| Spots on a bedroom ceiling near an outside wall | Cold corner with thin insulation |
| Gray film over the shower | Exhaust fan too small or not used |
| Musty smell in a spare room | Room kept closed without heat |
| Spreading stain under a sink | Slow plumbing leak |
Cost factors
Angi's Seattle cost guide says most pros charge $10 to $25 per square foot, with bathroom jobs at $425 to $825; prices for a Mason County address can differ, including for travel. The size of the area, material that has to be removed, containment and fixing the leak or fan all affect the total. Rebuilding permits come from Mason County Community Development, which also runs the Permit Assistance Center. Washington has no state mold license, so confirm L&I registration before hiring.
