Crawl Space Insulation in Rockford, IL

If your home has any crawl spaces that aren’t insulated, you’re missing out on a huge opportunity to maximize energy efficiency and savings. In fact, crawl spaces are a big source of air leakage—for an area so small, a crawl space offers huge energy savings if properly insulated.

Do you need to insulate your home’s crawl space? If you live in Rockford, Illinois, you’ve come to the right place! ThermaSeal / Lakeside Insulation serves the entire area, every neighborhood. Contact us today if you need crawl space insulation for your home.

Insulating Crawl Spaces

If you have a ventilated crawl space, our insulation contractors can insulate the subflooring and between the floor joists. If your crawl space is unventilated, it’s recommended to insulate the walls. Whether your crawl space is ventilated or unventilated, sealing is also extremely important. Air sealing and insulation are services that often go hand in hand because air leaks can greatly compromise the performance of insulation.

Benefits of Crawl Space Insulation for Your Rockford Home

Is crawl space insulation worth it? In a word, yes! Crawl space insulation offers a number of different benefits beyond just improving your home’s energy efficiency. In addition to lowering your monthly bills, crawl space insulation:

  • Makes your home more comfortable year round
