Crawl Space Repair Companies in California

Do you want a mold and rot free crawl space and energy bills as low as possible in your California home? If the answer is YES, then you've come to the right place. Whether you live in San Francisco, Sacramento, Oakland, Los Angeles or San Diego, our certified crawl space contractors in your local areas are ready to help you find the right solutions to your crawl space problems. They offer FREE basement or crawl space Estimates and Inspections!

Crawl space moisture in California is one of the major crawl space problems in many homes. Water underneath your house - in the form of condensation, water vapor, or liquid - is a recipe for rot as well as unhealthy mold that can be sucked up into your home. And a dirt, vented or unconditioned concrete crawl space under a home is a very bad idea. The earth has very high humidity in the soil. The natural airflow in a house is from bottom to top. This sucks the moist air and everything in it up into the living areas of the home. Mold spores, odors, humidity and critters create a very unhealthy environment. Many people in California experience a host of symptoms and don't realize that their dirt crawl space is affecting their health.

Now there is a solution to dirt crawl spaces - The CleanSpace System - developed by Basement Systems, the world leader in dry basement and crawl space technology.

CleanSpace Crawl Space Encapsulation System

The CleanSpace Encapsulation system is a crawl space vapor barrier system that completely isolates your home from the earth, dramatically reducing the humidity level in the air. Lower humidity levels reduce or, in some cases, eliminate mold growth, rot, and critters from your crawl space, making the entire house healthier. An independent study revealed that homeowners who properly fix their vented firt crawl space can save 15% - 20% on their heating and air conditioning costs!

Whatever your issue, we have the products and experience that you need to find the best solution. Click here to contact us or call 800-638-7048 to schedule a free quote for your crawl space repair project. We service all of the state of California, including San Francisco, Los Angeles, San Diego, San Jose, Sacramento and Oakland.

Crawl spaces have a bad reputation —as cramped, damp, dirty spaces that harbor bad-smelling mold, insects and other pests. The CleanSpace system of crawl space repair is designed to turn this ugly area into an asset —a part of your house you can actually be proud of. Our trained technicians make this transformation possible by combining waterproofing techniques with high-performance insulation, durable moisture barriers and effective air-sealing strategies.
