Woodinville Attic and Crawl Space Services
Woodinville homes sit on larger lots than most of our service area. Many are on wooded or semi-rural parcels on Hollywood Hill, around Cottage Lake, and in the hills east of the valley. More land means more trees, more outbuildings and more wildlife close to the house — and attics and crawl spaces that show it.
Living close to the woods
Rodent pressure on wooded and rural lots is constant, not seasonal. Wood piles, outbuildings, chicken coops, compost and bird feeders all support rodent populations near the house. Exclusion on these properties has to be thorough: every vent, every penetration and every roof-to-wall joint. We also note the site conditions that attract rodents, because sealing a house that sits next to a feed source is a constant contest.
Larger houses, larger crawl spaces
Custom and semi-custom homes here often have crawl spaces over 2,000 square feet, sometimes with ductwork and a furnace below the floor. Large crawl spaces with mechanical equipment are good candidates for encapsulation: the equipment works in drier air and the ducts lose less heat.
Valley and hill differences
On the valley floor near the Sammamish River, groundwater is closer to the surface. On the hills, slopes and springs can drive water toward one side of a foundation. We look at where the house sits before deciding on drainage.

Woodinville questions
We are on a well and septic. Does that change crawl space drainage?
It changes where water can go. Sump discharge must stay clear of the septic drain field and the well. We plan the discharge route around both.
Do you do outbuildings?
Our focus is the main house. We can include an attached garage attic or a crawl space under an attached structure; detached outbuildings are outside our scope.
