Crawl space cleaning built around Olympia houses
Under an older South Capitol or Bigelow Highlands bungalow, the crawl space is often a patchwork. Part of the house may sit on a low concrete foundation, part on old posts and piers added during a remodel, and the ground in between is bare dirt that stays damp much of the year. After a long Olympia winter, we find puddles in low corners, fallen batts that have turned black, old heating ducts coming apart and rodent nests tucked against the warmest part of the floor. Damp soil and debris give off that musty smell homeowners notice through the floor registers.
Cleaning comes first, and it is thorough. We document the space with photos, then remove debris, old plastic and fallen insulation by hand, bagging it before it leaves the crawl space. Rodent droppings are misted and picked up, never swept dry, because they can carry hantavirus. The soil and framing are treated with an antimicrobial. Because standing water is common in Olympia crawl spaces, we note where it collects and whether gutters, downspouts or grading are sending water toward the house. With the space clean and the water sorted, a sealed vapor barrier and new insulation can go in to keep it that way.

Local conditions
What Olympia throws at attics and crawl spaces
The houses
Olympia's oldest homes sit close to the Capitol. The South Capitol neighborhood, Bigelow Highlands and parts of the Eastside and Westside are full of Craftsman bungalows, cottages and a few Victorians from the 1890s through the 1930s, many on post-and-pier or early concrete foundations with low crawl spaces and partial basements. Post-war ramblers and 1960s and 1970s split-levels fill much of the Eastside and Northeast. The Westside and Cooper Point areas add newer subdivisions from the 1980s through the 2000s, with truss attics, vaulted ceilings and blown-in insulation.
The weather
Olympia gets noticeably more rain than Seattle, and the wet season runs long. The city wraps around the south end of Budd Inlet, where the Deschutes River meets salt water, and fog settles in the low areas on fall and winter mornings. Clear winter nights often turn colder here than in Seattle, so frost forms on roofs and inside poorly ventilated attics. Heavy fir and maple canopy keeps many lots shaded and damp.
The wildlife
Norway rats are common along the Budd Inlet waterfront, the port area and downtown, and they move into crawl spaces from there. Roof rats and squirrels use the dense tree cover in older neighborhoods to reach rooflines. Wooded areas such as Priest Point Park and Watershed Park bring raccoons and other wildlife close to homes, and ravines give rodents shelter right behind backyards.

FAQ
Crawl space cleaning in Olympia: FAQ
Still unsure? Call (800) 674-4933 and talk it through with us.
Is it normal to have water in my Olympia crawl space?
It is common, but it is not something to leave alone. Long rainy stretches, downspouts that empty near the foundation and lots that slope toward the house all send water under the floor. A little damp soil is expected. Standing water means something outside needs correcting. We photograph it and point you to the likely cause.
Will cleaning the crawl space help the smell in my house?
Often, yes. Musty odors usually come from wet insulation, debris and rodent waste under the floor. In homes with ducts in the crawl space, leaks pull that air into the heating system. Removing the source and sealing the ducts usually takes care of it.
