From Flour Mill to Commuter Town
Spray Foam Insulation in Yukon spans several building eras. Wikipedia notes that Oklahoma City annexed nearly all the land around Yukon in the 1960s, which set off a boom in home building, and the population jumped from 3,076 in 1960 to 8,411 in 1970 and 17,112 in 1980. Newer subdivisions have kept coming since, and by 2020 the town had 9,792 housing units, 71.1 percent of occupied homes owned by the people living in them.
1960s to 1980s homes
Houses from Yukon's first boom are mostly one-story ranches with brick fronts and simple attics. Forty to sixty years on, their insulation has usually settled to well below today's targets. Sealing the attic floor and blowing fill to depth makes them noticeably more comfortable in July.
Newer subdivisions
Yukon's newer neighborhoods have larger homes, many with bonus rooms and complex rooflines. Builders typically blew insulation to the code minimum, and Canadian County sits in Climate Zone 3A, where Oklahoma's code calls for R-30 ceilings. The Department of Energy suggests more for existing Zone 3 attics. We look for thin spots near the eaves, unsealed attic hatches and rooms over garages.
Shops and garages
West of town toward El Reno there is more acreage, and with it more shops, detached garages and steel buildings. Closed-cell spray foam on steel stops dripping and slows heat gain, which makes those buildings usable in summer.
Wheat country heritage
Yukon started as a mill town, and Wikipedia notes the Yukon Mill and Grain Company opened in 1893. The land around it is still flat and open toward the west, so homes on the edge of town take the afternoon sun and the prevailing wind with little shade. West-facing rooms and garages heat up fast. Besides the attic, we often recommend insulating the wall between an attached garage and the house, and sealing the attic hatch in the garage, which in many Yukon homes opens straight into the main attic.
Owners first
With only 0.9 percent of owner homes vacant in 2020, Yukon is a town of settled homeowners. That makes long-term upgrades like attic sealing and foam in bonus rooms easier to justify. Get a free estimate

Yukon Questions
What insulation upgrade helps a 1970s Yukon home most?
Sealing the attic floor and adding blown-in insulation to R-38 or more. It is affordable and makes a clear difference in summer.
Do you insulate shops near Yukon?
Yes. Closed-cell foam on steel shops and garages is common west of town, and we size it to whether you just want to stop dripping or plan to heat and cool the space.
My newer Yukon home has a hot bonus room. Why?
Bonus rooms often have kneewalls, sloped ceilings and a garage below that were insulated to the minimum. Foam or added insulation in those areas usually fixes it.
My attic hatch is in the garage. Does that matter?
Yes. A garage hatch is often unsealed and uninsulated, which lets garage and attic air mix. Weatherstripping it and adding an insulated cover is a quick, low-cost fix.
