Two Kinds of Wilsonville Clients
Our work as insulation contractors in Wilsonville splits between two kinds of clients: people who live in the house, and people who rent it out. In the 2020 census, 49.4% of occupied homes in the city were owner-occupied and 50.6% were rented. That near-even split changes how we talk about a job. An owner-occupant wants comfort and lower bills. A landlord wants fewer tenant complaints, fewer service calls and a property that holds up between tenants.
For homeowners
If you live in your Wilsonville home, start with the rooms that bother you. Cold upstairs bedrooms, a hot second floor in summer and drafty corners usually trace back to the attic or to walls that were never filled. We measure, look for air leaks and give you a written plan. Summer matters here as much as winter: Wilsonville's record high was 116°F on June 28, 2021, and an attic that is well insulated and sealed keeps the upper floor from soaking up that heat.
For rental owners
Rental properties take a beating. Insulation gets disturbed when cable or internet lines are run, bath fans may be left venting into the attic, and pests can move in between turnovers. A vacancy is a good time to deal with it. We can:
- Inspect and photograph attic and crawl space conditions for your records
- Remove soiled or damaged insulation and replace it
- Add blown-in insulation and air sealing so units are easier to heat
- Coordinate access with a property manager
You receive a written scope and photos so you can keep documentation with the property file.
Neighborhoods with their own story
Wilsonville's neighborhoods were built at different times and for different purposes, so insulation needs vary across town.
Villebois, on the western edge, is a primarily residential planned community built on the former grounds of Dammasch State Hospital, which opened in 1961 and closed in 1995. Its school opened in 2012 and the community center in 2013, so many homes there are relatively recent; the usual work is topping up attics and fixing specific cold rooms.
Charbonneau is a planned community on the south bank of the Willamette, separated from the rest of the city by the river and home to its only golf course. It is reached across the Boone Bridge on Interstate 5. Homes there are an established part of the city, and attic and crawl space condition varies house to house, so we inspect before recommending anything.
Rain season and crawl spaces
Wilsonville averages 42.62 inches of precipitation a year, most of it from November through March, with December the wettest month at about 6.6 inches. Homes with crawl spaces benefit from a sound ground vapor barrier and insulation that stays tight to the subfloor through that wet stretch. If we find fallen or wet insulation underneath, we will tell you why and what to fix first.
Which county are you in?
Most of Wilsonville is in Clackamas County, but the northern part of the city is in Washington County. For most insulation work that does not matter, but if a project grows into a remodel, permitting questions go to the city and the right county. We will help sort that out before work starts.

Wilsonville Background
- Owners and renters near even. The 2020 census counted 11,128 housing units in Wilsonville, with 49.4% of occupied homes owner-occupied and 50.6% renter-occupied. Recent Census estimates put ownership at 49.0%.
- Heat and cold records. Wilsonville's record high is 116°F on June 28, 2021 and its record low is −15°F on December 23, 1998. Annual precipitation averages 42.62 inches, with December the wettest month.
- Villebois on a hospital site. Dammasch State Hospital opened on the city's west side in 1961 and closed in 1995. Its grounds were redeveloped as Villebois, a mostly residential planned community whose community center was completed in 2013.
- Boones Ferry roots. Alphonso Boone started the Boones Ferry across the Willamette in 1847. The community took the Wilsonville name in 1880 and incorporated in the late 1960s with about 1,000 residents.

Wilsonville Questions
I own a rental in Wilsonville. Is insulation worth it?
Often, yes. Better attic insulation and air sealing make a unit easier to heat and more comfortable for tenants. The best time is during a vacancy, when we can get into the attic and crawl space without disturbing a tenant. We provide photos for your records.
My Villebois home is fairly new. Why is one room cold?
Newer homes can still have gaps: a missed section of attic, a room over a garage or knee walls without an air barrier. We find the specific cause rather than recommending a whole-house job you may not need.
Does insulation help during summer heat waves?
Yes. Attic insulation and air sealing slow the heat moving from a hot attic into the rooms below. Wilsonville reached 116°F in June 2021, and homes with well-insulated attics hold cooler upstairs temperatures during spells like that.
Do you work in Charbonneau, south of the river?
Yes. Charbonneau is part of Wilsonville, and we serve homes on both sides of the Willamette.
