If your home has a crawl space, it plays a much bigger role in comfort and energy efficiency than most homeowners realize. An uninsulated or poorly insulated crawl space can allow cold air, heat, and moisture to move freely into your home, driving up energy bills and creating uncomfortable indoor conditions.
At OJ Insulation, we help California homeowners protect their homes from the ground up. With more than 25 years of experience insulating homes across Southern California, our team understands how to properly insulate crawl spaces for our region’s climate, soil conditions, and construction styles.
Crawl spaces are one of the largest sources of energy loss in a home. Without proper insulation and air sealing, outside air and ground moisture can enter your living space year-round.
Proper crawl space insulation can help lower heating and cooling costs, improve indoor comfort throughout the home, reduce drafts and cold floors, support better indoor air quality, improve HVAC efficiency, and help protect your home from moisture-related issues. Many homeowners notice improved comfort almost immediately after insulating their crawl space.

Insulating a crawl space is not just about adding insulation. It requires the right approach based on the type of crawl space, ventilation, and moisture conditions. Our experienced insulation professionals evaluate your home and recommend the best solution for long-term performance.
In ventilated crawl spaces, insulation is typically installed under the subfloor and between the floor joists. Proper air sealing is also important to help reduce drafts and energy loss while maintaining ventilation.
For unventilated crawl spaces, insulation is commonly installed along the crawl space walls along with appropriate sealing and moisture control measures. This helps bring the crawl space into the home’s thermal envelope, improving comfort and energy efficiency.
If you are not sure what type of crawl space your home has, our team will inspect it and explain your options clearly and honestly.
