St. Louis homes have a median build year of 1966, and the city has 1,710 housing units, many with shallow attic insulation, open crawlspaces or bare rim joists. Energy Plus Home Improvements is based in Riverdale, about 11 miles west, and our crews have insulation, roofing and door projects across the city, including work through the City of St. Louis Homeowner Rehab program. We match the work to the house: blown-in cellulose for open attics, closed-cell spray foam for rim joists, sill plates and vaulted ceilings, and liners for crawlspaces. Every installation is backed by the EP Protection Plan™.

Quality You Can Trust
Many St. Louis ranches and additions sit over crawlspaces, and an open crawlspace lets cold, damp air under the floors all winter. We cover the ground with a sealed liner, spray closed-cell foam on the walls and sill plates, and seal the openings, as on our Fox Drive project. Vaulted ceilings have no attic above them, so closed-cell foam is often the only way to add real R-value there.
The U.S. Department of Energy recommends R-49 to R-60 for Michigan attics. On the Chippewa project, the attic went to 16 inches of cellulose, about R-49, with baffles at every eave so the soffit vents stay open and the roof deck stays cold.
We also install EP FoamCore™ open- and closed-cell spray foam, EP RetroCore™ wall insulation and EP CrawlGuard™ crawlspace encapsulation. Final pricing is confirmed after we inspect the home.
We are a participating contractor in the City of St. Louis Homeowner Rehab program and follow its payment schedule and guidelines on qualifying projects. Contact the city about eligibility, and we will work within the program’s requirements.
Inside the city, start with the City of St. Louis at City Hall, 300 N. Mill St.; homes in Bethany and Pine River townships follow the township or county process. We confirm the requirement for your address and pull the permit when one is needed.
Local Expertise
St. Louis sits at the geographic center of Michigan’s Lower Peninsula; a stone placed by Sidney S. Hastings in 1876 still marks the spot in Clapp Park, where a sign on M-46 calls the city the Middle of the Mitten. The town grew along the Pine River near the Bethany Lutheran Mission, established in 1848.
Housing ranges from older homes near downtown and the river to postwar ranches with crawlspaces and additions. Each estimate states the conditions we found, the work we recommend, and anything we cannot confirm until we are in the attic or crawlspace.

Our St. Louis insulation projects include two crawlspaces on Fox Drive lined with White Cap 12-mil liner, about 750 square feet in all, with 56 linear feet of sill plate and a vaulted ceiling sealed with closed-cell spray foam, and about 1,040 square feet of attic on Chippewa blown to 16 inches of cellulose with 34 vent baffles. Every job starts with a moisture and air-leak inspection and ends with a final coverage check and full cleanup.

Answers to the questions we hear most often about insulation projects.
If the crawlspace has a dirt or gravel floor, damp air or cold floors above it, yes. A sealed liner and closed-cell foam on the walls keep moisture and cold air out from under the house.
The sill plate is the wood that sits on top of the foundation. Gaps there leak cold air into the house. Closed-cell spray foam seals and insulates it in one step.
Vaulted ceilings have little or no attic space, so blown insulation is not practical. Closed-cell spray foam gives the highest R-value per inch and seals air leaks at the same time.
Yes. We are a participating contractor and follow the program's guidelines and payment schedule. Contact the City of St. Louis about eligibility.
It depends on the scope and where the home is. Inside the city, check with City Hall at 300 N. Mill St.; township homes follow the township or county process. We confirm the requirement and pull the permit when one is needed.
