Maplewood Heights sits on the plateau above the Cedar River east of downtown Renton, with the Maple Valley Highway and the river running along its southern edge and the Maplewood golf course below the bluff. The houses on top are 1960s through 1980s ramblers and two-stories on crawl spaces, with 1990s plats toward the East Plateau and older homes down along the river flats near Jones Road.
The plateau houses have the standard Renton problems of wet crawl spaces and cold north walls. The river flats have the river. On December 11, 2025, an atmospheric-river storm pushed the Cedar past its 1990 record in Renton, covered Southeast Jones Road, and put water into homes in the Maplewood area; a crawl space that took river water that week will be a mold problem for years if it is not opened and dried.
Maplewood Heights homeowners who call this line reach one independent local mold provider who works the plateau and the flats. We connect the call and step aside.
A crawl space that flooded in December and a house that smells of it everywhere is whole-home mold remediation. A gray band on a north bedroom wall in a 1970s rambler is mold removal. Ducts that sat in a wet crawl space and a furnace that smells of it is HVAC mold cleaning.
The Cedar River below the bluff is the main source of drinking water for Seattle and much of King County, drawn off upstream at Landsburg; Seattle Public Utilities manages the protected watershed above it. Rebuild permits for Maplewood Heights addresses go through the City of Renton.
Call (425) 584-6572 and describe what the water did. We put you through to a local mold provider serving Maplewood Heights.
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.
