Cold floors in a Rochester Hills two story house usually trace back to one place: the rim joist, that ring of wood at the top of the basement wall that builders left bare for decades. Air pours through it all winter. Sealing it with closed cell foam is one of the fastest payback projects in insulation, and it is often where we start. From there we handle full attics, crawl spaces, walls, and additions with open and closed cell systems matched to the assembly. The goal is an air sealed house, not just a fluffier one. We walk the home first, show you where it leaks, and put the fix in writing. If your feet are cold every January, call us in the fall.
