Wyoming's Mid-Century Streets
Spray Foam Insulation in Wyoming usually means mid-century houses. The median home in Wyoming was built in 1969, according to ACS 2019 to 2023 figures on Point2, and about 10.4% predate 1940. Galewood, Urbandale and Burlingame were platted between 1890 and 1906, and Godwin Heights, Home Acres and Wyoming Park filled in during the 1920s on small, inexpensive lots. Most of the rest of the city grew in the decades after the war.
What we find in these houses
Small 1920s houses often have empty walls and a shallow attic with an inch or two of old fill. Post-war ranches and cape cods usually have some insulation, but it has settled, the attic floor was never sealed and the rim joist is bare. Those three spots, attic, rim and walls of the coldest rooms, are where most Wyoming jobs start.
Owners who stay
About 67.1% of Wyoming homes are owner-occupied. Insulation pays back over years, so it suits people who plan to stay. Rental owners also call us to fix cold units and ice dams before tenants complain.
Permits
Wyoming's Building Inspections department handles building, electrical, mechanical and plumbing permits and says most residential permits can be obtained in one to two weeks. Insulation by itself usually does not need one, but a basement finish does, and we fit our work into that schedule.
Small lots, close houses
The 1920s neighborhoods were built on narrow, inexpensive lots with little zoning, so houses sit close together and side walls can be hard to reach from outside. Filling those walls from inside through the plaster or drywall is often simpler than working in a tight side yard.
Soil and basements
Wyoming's soils vary: dark loam in the Buck Creek valley, dense clay on the higher ground and pockets of gravel and gypsum in the north. Clay holds water against foundation walls, so basements on higher ground are more likely to show damp spots. We check the walls before foaming and point out anything that needs drainage work first.
Where to start on a budget
If you can only do one thing this year, seal the attic floor and top it up. If you can do two, add the rim joist. Walls come next in the rooms that stay coldest.

Wyoming Questions
Do 1920s Wyoming houses have insulation in the walls?
Many do not. We check by drilling a test hole or looking at an outlet, and can fill walls with dense-pack or injection foam.
What should I do first in a 1950s ranch?
Seal and top up the attic and foam the rim joist. Those two steps usually make the biggest difference.
Do I need a permit for insulation in Wyoming?
Insulation alone usually does not. Basement finishes and remodels do, and the city issues most residential permits in one to two weeks.
Is clay soil a problem for basement insulation in Wyoming?
Clay can hold water against the wall. Foam is fine on a dry wall, but a wet one needs drainage fixed first.
