A cold garage floor in winter. A chilly basement that never quite matches the rest of the house. These spaces are often the last ones insulated, if they're insulated at all, and that leaves a thermal gap right next to the living areas you're paying to heat and cool.
Meridian Spray Foam Insulation closes that gap with foam on garage ceilings, shared walls, and basement rim joists and walls, the spots most installers skip entirely.
What's included
What's Included in Garage and Basement Foam
- Garage ceiling — foamed to stop heat loss into the space above, especially under bonus rooms
- Shared walls with living space — insulated so the garage doesn't pull heat from adjacent rooms
- Basement rim joists and walls — closed-cell foam for moisture resistance below grade
- Optional — mold-resistant coating for basements with a history of dampness
- Customer prep — clear stored items from garage and basement walls ahead of the spray day

Garage And Basement Spray Foam Insulation FAQs
Can spray foam insulation help lower my heating bill in a cold garage or basement?
Sealing the thermal gap at the garage ceiling or basement walls reduces how much heat the rest of the house loses to those spaces. Results vary by home, but it addresses a real source of heat loss.
Can I spray foam my own garage, or is it a bad DIY idea?
Box-kit foam struggles with ceiling overspray control and even coverage across a full garage, which usually means thin spots and a messy finish. A calibrated rig and a trained applicator avoid both problems.
What foam is used for basement walls versus garage ceilings?
Basement walls, being below grade, usually get closed-cell foam for its moisture resistance. Garage ceilings can use open-cell or closed-cell depending on what's above them and your budget.
Does garage insulation help if the garage isn't heated?
Yes. Even an unheated garage shares walls and sometimes a ceiling with conditioned space. Insulating that boundary reduces how much heat the house loses through it.
