Mold in Walls & Drywall in Bonney Lake, WA

Where is the water coming from?

Bonney Lake sits along State Route 410, with Lake Tapps and Fennel Creek below Victor Falls as its regulated shorelines. Unless your home is right on the water, though, wall mold almost always starts with something inside the house or in its outer skin. Look at plumbing walls first: shower valves, toilet supply lines, washer boxes and the sink base. Then check windows and exterior doors, where months of rain can work past caulk and flashing. Finally, consider condensation. A bedroom or closet on an outside wall that stays cool all winter can collect moisture behind a dresser, and the drywall paper feeds mold from behind. A company's moisture meter and thermal camera usually narrow this down in one visit.

I rent. Will the city inspect my unit?

Possibly, but there is a required first step. Bonney Lake Code Enforcement handles structures unfit for occupancy and unsafe structures, and investigations start only with a Request for Action form, not a phone call or email. For a rental's interior, the city will inspect only after the tenant has followed the RCW 59.18.115 landlord-notice process; landlord-tenant disputes themselves are civil matters. Start by giving your landlord written notice of the leak. State law requires landlords to keep units weathertight and walls and plumbing in reasonable repair. This is general information, not legal advice.

Do I need a permit to put the wall back together?

Bonney Lake says all new construction, demolition and alteration requires a building permit unless specifically exempt. Simple drywall replacement may or may not count, and framing, plumbing or electrical repairs found during removal are more likely to. The Permit Center in the Public Services Department issues permits, and Development Services runs inspections, so ask there before the wall is closed. Whoever does the rebuild should be registered with Washington L&I as a construction contractor.

A local note

The Tacoma-Pierce County Health Department's Healthy Homes program has mold resources for tenants and homeowners. For the wall itself, Angi's Seattle cost guide puts wall mold at roughly $825 to $16,550 depending on how much is opened and rebuilt.
