Crawl space cleaning built around Redmond houses
Homes on and near the Sammamish River valley sit on soil that holds water through the wet season. After a long stretch of rain, many of these crawl spaces have puddles, mud tracked across the plastic, and floor insulation that has wicked up moisture and fallen. Builders' scraps left behind in the 1970s and 1980s, like lumber offcuts, cardboard and old forms, rot in place and attract insects and rodents. Norway rats from the riverbank and nearby fields find this space ideal: dark, quiet, and full of soft nesting material. It's also the space directly under your floors, so its air rises into the house.
Cleaning a wet crawl space is a different job from cleaning a dry one. We start by documenting water, mud and damage with photos, and we tell you if drainage needs attention before cleanup will last. Then we pull out soaked batts, debris, and torn or buried plastic, remove droppings and nests, and sanitize affected areas. Once the ground is clear and the soil has had a chance to dry, we lay a new vapor barrier, reinstall floor insulation where needed, and seal foundation vents and gaps against rodents. The finished space gets photographed so you can compare it with where it started.

Local conditions
What Redmond throws at attics and crawl spaces
The houses
Redmond's housing climbs from the Sammamish River valley up onto the hills around it. Education Hill and Grass Lawn have 1960s and 1970s split-levels and ramblers, mostly on vented crawl spaces. Idylwood, near the north end of Lake Sammamish, mixes older lake homes with remodels. North Redmond and Bear Creek filled in through the 1980s, 1990s and 2000s with two-story homes on larger lots, many with crawl spaces, ducts running through the attic and roofs with several sections. Overlake and Downtown Redmond add townhomes and apartments. The older homes often still have their original ductwork and first-generation insulation.
The weather
The Sammamish River valley floor is flat, low and wet. Cold air settles there on clear winter nights, bringing fog and frost while the hillsides stay a little milder. Bear Creek and Evans Creek feed the valley, and the ground near them stays saturated through the October-to-May rain. Up on Education Hill and in North Redmond, tall second-growth firs shade roofs and drop needles that fill gutters.
The wildlife
Marymoor Park, the Sammamish River Trail, Bear Creek and the remaining farm fields in the Sammamish Valley give rodents plenty of habitat next to homes. Norway rats follow the river and creek banks and burrow under sheds and decks. Roof rats use wooded hillsides and fence lines to reach rooflines. Mice move indoors as fields are cut and nights get cold.

FAQ
Crawl space cleaning in Redmond: FAQ
Still unsure? Call (800) 674-4933 and talk it through with us.
Should I clean my crawl space in winter or wait for summer?
We clean year-round, but in valley homes with standing water it can help to deal with drainage first and lay the new barrier when the ground isn't flooded. After the inspection we'll tell you whether to proceed right away or stage the work. Rodent debris and soaked insulation should come out without waiting.
What happens to the old insulation and debris?
It's bagged in the crawl space, sealed, carried out and hauled away. Nothing contaminated is dragged loose through your house. Where droppings are present, our crew wets them down first instead of sweeping, because dry droppings can release hantavirus particles into the air.
