Spray Foam Insulation in Comstock Township, MI

Spray Foam Insulation in Comstock Township deals with homes along a river valley. The Kalamazoo River flows east to west through the middle of the township, and Morrow Lake, a reservoir formed by a dam near East Comstock, sits on its eastern side. The township was set off in 1834 and became a charter township in 1964; its population was 15,231 in 2020.

Low ground and damp foundations

Houses on lower ground near the river and lake can have damp basements and crawl spaces. Before we insulate anything below grade, we look for signs of water: efflorescence on block walls, stains, a sump that runs often. Closed-cell foam on the rim and walls works well in damp conditions because it does not absorb water, but it should not go on a wall that is actively leaking.

Crawl spaces and additions

Older homes in Comstock and its smaller communities (Comstock Northwest, East Comstock and Lawndale) often have additions over crawl spaces. Sealing the vents, laying a vapor barrier and foaming the crawl walls warms the floor above and keeps the crawl drier.

Rural lots

Farther from the city, larger lots often include pole barns and detached garages. Closed-cell foam stops the condensation drip off steel roofs and lets the building be heated.

Targets and rebates

Comstock is in Kalamazoo County's Climate Zone 5A. If your gas or electric comes from Consumers Energy, its rebate chart covers attic, wall, basement, crawl space and rim joist insulation.

Typical Comstock homes

Comstock's housing ranges from older homes near the river and the M-96 corridor to newer subdivisions and rural houses farther out. The township had 5,601 housing units at the 2000 census and has grown since. In older homes, the attic and rim joist are usually the first priorities; in newer ones, it is often bonus rooms, cantilevers and the attic hatch.

Closed cell vs open cell near the water

Below grade and near the river, closed-cell is the safer choice because it resists vapor and does not absorb water. Above grade, in walls being remodeled or rooflines with a good vapor plan, open-cell can do the job for less. We explain the choice for each area on your estimate.

What it costs

HomeGuide's national figures put rim joist foam at about $2,000 to $2,500 and crawl space foam at $2,000 to $4,000. Your price depends on the house, and the written estimate after our visit is what you pay.
