Spray Foam Insulation in St. Clair Shores, MI

Spray foam insulation in St. Clair Shores goes into homes on land that was farmed for two centuries. Wikipedia notes French settlers lived along Lake St. Clair as early as 1710, and the area stayed mostly rural into the early 20th century. Subdivisions such as Eagle Pointe, platted along the shore in 1916, were followed by dozens more across the farmland over the next decades.

Lake wind

Homes near the water face more wind than inland suburbs, and wind drives air through every gap in a house. Air sealing at the attic floor, rim joist, windows and doors matters more here.

Mixed housing ages

With subdivisions platted over several decades, St. Clair Shores has a mix of older cottages, mid-century homes and later houses. Some older lakeside homes sit on crawl spaces or partial basements. We seal and insulate crawl space walls with closed-cell foam, or insulate the floor above if the crawl stays vented.

Numbers

The 2020 census counted 58,874 residents and 28,507 housing units, 4.4% vacant. Macomb County is in Climate Zone 5A in Michigan's energy code.

Seasonal humidity

Lakeside air is humid in summer. Open-cell foam in a cold location can let moisture reach surfaces where it condenses in winter, so near the lake we lean toward closed-cell for rim joists, crawl spaces and roof decks. Attic floors still get sealed and blown with loose fill where there is good ventilation.

Additions and enclosed porches

Many homes here have added rooms, enclosed porches or second floors. The seams between old and new framing often leak, and enclosed porches may have little or no insulation. We look at each and list what each would take.
