Michigan Home Heat-Loss Scorecard
Where most homes in SW Michigan lose heat (and money)
Homeowners often ask: “Where does my house lose heat?” In Michigan, the biggest culprits are usually the attic, walls, rim joist, and crawl space/basement areas — plus leaky ductwork. Use this scorecard to spot the most common problem zones, then we can confirm the best fix during your free estimate.
Attic / Ceiling
Warm air rises. If your attic is under-insulated or not air sealed, heat escapes fast. This is often the #1 upgrade for comfort and savings.
Exterior Walls
Empty or underfilled wall cavities create cold rooms and uneven temperatures — especially in older homes. Sidewall cellulose can make a major difference.
Rim Joist / Band Board
Rim joists are a major air-leak zone. Even “good insulation” won’t fix drafts if air is moving through gaps. Closed cell spray foam is a common solution here.
Crawl Space / Basement
Heat loss and moisture issues often come from below. Sealing + insulating crawl space or basement walls helps reduce cold floors and humidity.
Ductwork (if applicable)
Leaky ducts in attics, basements, or crawl spaces can dump conditioned air into unconditioned areas. Sealing and insulating ducts can improve room-to-room comfort.
Fast Next Step
The biggest savings typically come from fixing the top of the home (attic) and the leakiest air zones (rim joists & penetrations). Greenshield Insulation will assess your home and recommend the best plan — with a free estimate.
