Benson Hill is the plateau south of Renton's old city limits, along Benson Road and Petrovitsky Road, and for most of its life it was unincorporated King County. Residents voted on November 6, 2007, to join the city, and the annexation brought in thousands of houses built from the 1960s through the 1990s: ramblers and split-levels near the older arterials, two-story plats from the 1980s and 1990s farther out toward Fairwood and Cascade.
The hill drains into the Soos Creek basin, and its crawl spaces are dug into glacial till that holds water through the winter. The 1960s houses have bare dirt under the floor and bath fans that were an afterthought; the 1990s houses have blown insulation covering the soffit vents and fans that end at the attic floor. A home inspection on Benson Hill finds a dark attic deck about as often as it finds a damp crawl space.
Benson Hill homeowners who call this number reach one independent local mold provider who works the whole plateau. We connect the call; the provider meters the house and writes the scope.
A crawl space that smells like wet earth under a 1960s rambler and a hallway that smells of it every fall is mold odor removal. Black plywood across the north slope of a 1992 two-story attic is attic mold remediation. A furnace in the garage pulling crawl-space air through a disconnected duct is HVAC mold cleaning.
Since the 2008 annexation, rebuild permits for most Benson Hill addresses go through the City of Renton rather than King County, while the Fairwood plats just east of the line still go through the county; the provider sorts out which desk your address uses before any wall is closed.
Call (425) 584-6572 and tell us where the house is wet. We put you through to a local mold provider serving Benson Hill.
Growth on drywall, a closet wall, or a window sill after nine wet months: room sealed, wet board cut to the meter line, framing HEPA-cleaned and dried.
A dark patch handled by how far the moisture reached, not its color: containment, porous material out, hard surfaces cleaned, source fixed before closing.
A crawl space, a roof leak, and a bathroom all feeding growth in one house, mapped room by room and cleared in zones as one project.
Furnace cabinet, coil, and the ducts that run through a damp crawl space cleaned when the heat comes on in October and the house smells wrong.
Spots on a bathroom ceiling with a weak fan, growth behind a vanity or under a shower pan, removed with the leak or the venting fixed first.
Dark sheathing under a roof that drips condensation all winter, cleaned and treated once the bath fans vent outside and the soffits breathe.
A musty smell that climbs out of the crawl space every November, traced to the wet joists or insulation under the floor, then removed and treated.
Drywall, trim, subfloor, and insulation put back after removal, once the framing reads dry and whatever let the water in is repaired.
