A Small City of Newer Homes
Spray Foam Insulation in DeWitt is mostly about getting newer homes the rest of the way to comfortable. More than 80% of DeWitt's occupied homes are owner-occupied, and the median home was built in 1985. About 16% of the housing went up from 2010 onward, and the 2020 census found a vacancy rate of just 3.0%.
Typical DeWitt jobs
Finishing the basement and wanting foam on the rim joist and concrete walls first. Cold floors in a bonus room over a three-car garage. Attics where the blown insulation has settled or was never evenly spread. A sunroom or addition that runs colder than the rest of the house. Most of these are a day of work or less.
Older homes in town
The older homes near the center of town, from a village incorporated in 1929 that became a city in 1965, need the full treatment more often: attic sealing, rim joist foam and wall insulation where cavities are empty. About 9% of DeWitt's housing dates from 1939 or earlier.
Near the river
DeWitt sits on the Looking Glass River, a Grand River tributary. Homes on low ground near the river can have damp basements, so we check for water before insulating.
Township properties
Outside the city limits, DeWitt Township and the surrounding rural area add larger lots with detached garages and pole buildings. A heated shop needs foam on the walls and roof; a cold-storage building may only need a coat on the roof steel to stop drip.
Finished basements done right
Most basement finishing in newer homes goes wrong in the same place: fiberglass batts against cold concrete with plastic sheeting over them, which traps moisture. Closed-cell foam on the concrete avoids that, and the framing can go right in front of it.
Garages and mudrooms
DeWitt homes with attached garages often have a mudroom or laundry between the garage and the kitchen. That wall and the door to the garage are common leaks. We seal and insulate the shared wall and check the door's weatherstripping.

DeWitt Questions
I'm finishing my DeWitt basement. What should I insulate first?
The rim joist and the concrete walls, before framing. Closed-cell foam handles both and keeps moisture off the walls behind the new drywall.
Why is the room over my garage so cold?
Cold air under the floor, gaps where the floor meets the kneewalls, and thin insulation in the floor bays are the usual causes. Foam in the floor framing solves most of it.
How do I know if my attic needs more insulation?
If you can see the tops of the ceiling joists, or the insulation is less than about 13 to 14 inches deep, you are below the R-49 ENERGY STAR suggests when adding insulation in this zone.
How thick should basement wall foam be?
Around 2 inches of closed cell gives roughly R-12 to R-14 and acts as a vapor retarder, which meets or beats the R-10 continuous option in Michigan's 2015-based code for Zone 5 basement walls.
Do you insulate detached garages?
Yes. We size the foam to whether you heat the garage or just want to stop condensation.
