Insulating Older Mount Morris Homes
Spray Foam Insulation in Mount Morris is mostly about older houses. Point2Homes' census summary shows 18.3% of homes were built in 1939 or earlier, 22.7% in the 1940s and 26.6% in the 1950s, so about two-thirds of the city's housing predates 1960. About 72.4% of units are detached houses.
A railroad village
Mount Morris was named after Mount Morris, New York, where many early settlers came from. A post office opened in 1837, the Pere Marquette Railway line came through in 1857, the settlement was platted as Dover in 1862, incorporated as the village of Mount Morris in 1867 and became a city in 1929. Wikipedia lists 1,460 housing units in 2020.
1940s and 1950s houses
Wartime and postwar houses here tend to be small, simple and under-insulated: thin attic insulation, empty or nearly empty walls and bare rim joists. On a small house, sealing the attic and blowing it to depth, dense-packing the walls and foaming the rim can be done in a couple of days and make a big difference in comfort.
Storm history nearby
The 1953 Flint-Beecher tornado, an F5 and the deadliest in Michigan history, struck the area just southeast of here. Many homes in the area were built or rebuilt in the years after.
Attic access
Many small houses here have only a tiny scuttle hole into the attic. We work through it where we can, and add or enlarge an insulated hatch if needed.
Small houses, big gains
A 1940s house of 900 to 1,100 square feet has a small attic and a short rim joist, so a full air seal and insulation package costs far less than in a large house, while the comfort gain is just as noticeable. HomeGuide notes many foam installers have a job minimum of $1,000 to $2,000 or more, so bundling the rim joist with attic sealing usually makes the most sense.

Mount Morris Questions
Is it worth insulating a small 1940s house?
Yes. Small houses are quick to do, and sealing the attic, filling the walls and foaming the rim often makes the biggest difference per dollar.
Can you insulate walls in a house with old wiring?
We check first. Knob-and-tube wiring should be inspected or replaced before walls are filled.
My attic hatch is tiny. Can you still insulate?
Usually yes. If not, we can install a larger insulated hatch.
Is there a minimum job size?
Many foam jobs have a minimum, often $1,000 to $2,000 or more per HomeGuide, so combining areas usually makes sense.
