The right crawl space insulation helps keep floors warmer in winter and supports lower energy bills, but only if it is the right type for your crawl space and stays dry. Home Run installs crawl space insulation for homes in Covington, Conyers, McDonough and nearby Georgia communities.
Signs Your Crawl Space Insulation Isn’t Working
- Cold floors in winter, especially over the crawl space
- Fiberglass batts sagging, hanging or lying on the ground
- Insulation that is damp, stained or smells musty
- Higher heating and cooling bills than similar homes
- No insulation at all under the floor or on the walls
Choosing the Right Approach
- Vented crawl spaces are typically insulated between the floor joists. Fiberglass in these spaces often absorbs humidity, sags and falls over time
- Sealed or encapsulated crawl spaces are usually insulated on the foundation walls with rigid foam board, keeping the whole crawl space closer to indoor temperatures
- Rim joists are a common source of air leaks and heat loss and are often insulated with rigid foam or closed-cell spray foam
Insulation That Lasts
Insulation only works if it stays dry. We check for moisture problems first and recommend fixing them before new insulation goes in. If old insulation is wet or damaged, we remove it first with crawl space insulation removal.
Crawl Space Insulation FAQs
Should I insulate the floor or the walls?
It depends on whether the crawl space is vented or sealed. Vented crawl spaces are usually insulated at the floor; sealed crawl spaces are usually insulated at the walls. We will explain which is right for your home.
Why does my fiberglass insulation keep falling down?
Fiberglass absorbs moisture in a humid crawl space, gets heavy and sags out of place. Addressing the moisture is key.
