Crawl Space Insulation Contractors in Santa Monica, CA

If you’re trying to lower your energy bills, one of the best ways to do this is by re-insulating your home. And when it comes to insulating your home, the crawl space holds a lot of potential!

The lower levels of homes—the basement and crawl spaces—are very high-moisture areas that are prone to leaking, mold development and more. This can really compromise the energy efficiency of your home, so it’s important that these areas are properly insulated. In fact, if your crawl spaces aren’t insulated, you could be losing a lot of money due to lost energy (crawl spaces are big sources of air leakage!).

Crawl Space Insulation Installation

If your Santa Monica home has any crawl spaces, they need to be insulated—no doubt about it. Insulation, however, isn’t the only thing to consider. Your crawl space should also be properly weatherized and sealed. Air leaks decrease the effectiveness of insulation, no matter where it’s installed (crawl space, attic, basement, etc.). So if your crawl space is insulated but not sealed, you could end up dealing with problems like moisture infiltration, soil vapor intrusion (which can reduce indoor air quality), and more.

Ventilated vs. Unventilated Crawl Spaces

Is your crawl space ventilated or unventilated? If you aren’t sure, that’s okay—our experienced Santa Monica home insulators will be able to tell you! Both types of crawl spaces need to be insulated, but depending on whether it’s ventilated or not, you’ll need to go about it a little differently. Ventilated crawl spaces should be insulated between the floor joists and under the subflooring. If your crawl space is unventilated, the walls should be insulated, and sealing isn’t as urgent because air and moisture infiltration isn’t as big a problem.

Although you don’t think about the lower levels of your home in Santa Monica, particularly if you have a crawl space or unfinished basement, they can truly maximize the energy efficiency of your home. This means lower energy bills for you! Whether insulated with fiberglass, cellulose or foam, crawl space insulation can also make your home more comfortable year round.
