Insulating Homes in Grand Junction
Spray Foam Insulation in Grand Junction works in a cold semi-arid climate at about 4,646 feet. The city's 1991-2020 climate normals list a January mean of 27.4F, about 17.7 inches of snow a year, July highs averaging 94.5F and only about 9 inches of precipitation. The average first freeze arrives around October 11 and the last around April 25, so heating season is long, and the city also averages roughly 68 days a year at or above 90F.
A city of many eras
Grand Junction was incorporated on July 22, 1882, the year after the area opened to settlers, and grew as a farming, fruit-growing and ranching center. The 2020 census counted 29,431 housing units in the city, with a 1.7% homeowner vacancy rate. Older homes near downtown, mid-century ranch houses and split-levels across the middle of the valley, and newer subdivisions on the edges all need different things.
What we usually find
In older houses: little or nothing in the walls, a few inches in the attic and open rim joists over crawl spaces. In mid-century ranches and split-levels: settled blown-in, leaks where split-level rooflines meet, and crawl spaces with fallen batts. In newer homes: decent depth but missed air sealing at kneewalls, chases and duct boots. The quote addresses what we actually find.
