Saginaw has some of the oldest housing in our service area, from lumber-era homes near the Saginaw River to postwar ranches and newer homes in Saginaw and Thomas townships. Older homes often have little wall insulation and leaky attics; many ranches sit over crawlspaces. Energy Plus Home Improvements has served Mid-Michigan since 1971 from Riverdale, about 44 miles west of Saginaw. We spray foam crawlspaces and rim joists, air seal and insulate attics, and add wall insulation. Every installation is backed by the EP Protection Plan™.

Quality You Can Trust
In a crawlspace, closed-cell spray foam does three jobs: it insulates the walls, seals air leaks at the sill and rim joist, and resists moisture. That makes it the right choice for a space like the one on South Thomas Road, where the goal is warmer floors and a drier space under the house.
Lumber-era and early 1900s homes often have empty wall cavities. EP RetroCore™ wall insulation fills those cavities with dense-pack cellulose or injection foam through small access holes, which are then plugged and finished.
We also install EP FoamCore™ spray foam and EP CrawlGuard™ crawlspace encapsulation. Final pricing is confirmed after we inspect the home.
Many Saginaw addresses are in Saginaw, Thomas, Kochville or other townships, each with its own building department; homes in the city follow the City of Saginaw’s process. We confirm the requirement for your address and pull the permit when one is needed.
Local Expertise
Saginaw began with Fort Saginaw, built by the U.S. Army on the west bank of the Saginaw River in 1822. The west-side settlement became a city in 1857, and the state merged it with East Saginaw in 1889. Logs floated down the river to Saginaw’s sawmills, and lumber production peaked in the early 1870s.
Housing ranges from lumber-era homes near the river to postwar ranches and newer subdivisions in the townships. Each estimate states what we found, what we recommend, and anything we cannot confirm until we are in the crawlspace, walls or attic.

Answers to the questions we hear most often about insulation projects.
Yes. It insulates, seals air leaks and resists moisture in one layer, which makes it a strong choice for crawlspace and basement walls.
Usually. EP RetroCore™ fills wall cavities through small holes that are plugged and finished afterward.
Start with the area that loses the most heat or causes the most comfort problems. In many Saginaw homes, that is the attic or the crawlspace.
The Department of Energy recommends R-49 to R-60 for Michigan attics. EP ComfortCore™ 16 reaches about R-49 and EP ComfortCore™ 20 about R-60 or more.
It depends on the scope and whether the home is in the city or a township. We confirm the requirement for your address and pull the permit when one is needed.
