Trusted Radon Testing & Mitigation Company in Niantic, CT

This homeowner in Niantic, CT reached out because the insulation was falling out of the ceiling in his basement. In a basement, the “rim joist” is the perimeter of the floor framing system along the exterior of the house. The joints and gaps between all the framing members allow for a lot of air leakage into the house. The rim joist is seldom insulated and never air sealed. Basement ceiling insulation, especially fiberglass batts, doesn’t stop the flow of cold air into the home. Results - cold floors, drafty, uncomfortable rooms, cold basement/lower level, higher heating and cooling bills and more condensation in the basement or crawl space in the summer.

We had the perfect solution for this homeowner. In this solution, we spray foam the rim joist in the basement in order to seal and insulate it. Two part expanding spray foam is installed on the rim joist and over the sill plate to seal all air leaks from the outside and insulate this important area of the home. Our spray foam has a high insulation value per inch of R7, and because it expands, it seals all cracks and gaps and joints where air from the outside enters the home. Results - warmer floors, less drafts, more comfortable rooms, the house is easier to heat and costs less to heat, less summertime condensation on cold basement surfaces.
