Built Fast After the War
Spray foam insulation in Livonia fits a city that grew quickly from a township. Livonia Township was organized in 1835, but the city was incorporated in 1950, and most of its housing went up in the decades after. By 2020 it had 95,535 residents and 40,380 housing units with only 2.7% vacant and a homeowner vacancy rate of 0.7%. Homes here are full and lived in, and owners tend to stay.
What post-war homes need
Houses built in the 1950s and 1960s generally had some insulation from the start, but far less than today's targets. A few inches in the attic is common, often compressed and disturbed by decades of wiring and fixture work. Rim joists are usually bare. Rooms over attached garages run cold. Many of these homes also have a crawl space or a low basement under part of the house.
The usual plan
For a typical Livonia house we seal the attic floor and blow it to depth, spray closed-cell foam on the rim joist, and look at any room over the garage. If you are finishing the basement, foam on the walls and rim before framing is the efficient way to do it.
Code and climate
Livonia is in Wayne County, which Michigan's energy code lists in Climate Zone 5A. Michigan's residential code sets exterior footings 42 inches below grade, a reminder of how deep winter cold reaches around a basement.
Attic hatches and bath fans
In post-war ranches the attic access is often a simple panel in a hallway or closet ceiling, with no insulation or weatherstripping. Bath fans frequently vent into the attic instead of outside, which puts warm, wet air right where it causes frost and mold on the roof deck in January. We insulate and weatherstrip the hatch, and point out any fan that needs to be ducted outside before we bury the area in new insulation.

Livonia Questions
My Livonia ranch has a room over the garage that is always cold. Can you fix it?
Usually. Closed-cell foam in the floor framing over the garage seals out cold air and garage fumes and insulates in one step. We also check the walls and ceiling of that room.
Is my 1950s attic insulation enough?
Probably not by today's targets. The Department of Energy suggests adding R-49 over 3 to 4 inches of existing insulation in Zone 5. We measure and tell you.
Do you do crawl spaces?
Yes. We insulate crawl space walls and rim joists with closed-cell foam, or the floor above when the crawl stays vented.
Should a Livonia ranch get spray foam in the attic?
Usually not across the whole attic floor. Sealing leaks with foam and then blowing cellulose or fiberglass to depth costs less for a typical ranch attic. Foam makes more sense on rim joists and garage ceilings.
