What is Crawl Space Encapsulation?
Crawl space encapsulation involves sealing your crawl space with a durable vapor barrier, insulating the walls, and can include installing a dehumidifier. This process creates a dry, conditioned space that prevents moisture intrusion and enhances your home’s overall health and efficiency. We tailor our services to meet the unique needs of each crawl space. Sealing your home’s crawl space provides:


Our Crawl Space Sealing Process
Install Vapor Barrier
Moisture enters a crawl space from the ground and walls. A high quality vapor barrier is installed over the ground.
Seal Seams & Vents
All vapor barrier seams and overlaps are sealed with specialized tape to prevent moisture from entering. Vents are sealed to keep unconditioned air out of the crawl space.
Insulate Walls & Band Joist
Closed cell spray foam is the best solution. Spray foam provides the
best insulating and air sealing properties
Condition the Air
There are three methods of
conditioning: dehumidifier, a small amount of air supply from the HVAC system, or a small exhaust fan.
Crawl Space Waterproofing
Our crawl space waterproofing drainage system effectively protects your home by diverting water away from the foundation, preventing costly damage and moisture-related issues. Using advanced French drain technology, we ensure a dry, stable crawl space that enhances air quality and energy efficiency. Trust our expert installation to safeguard your property’s value and structural integrity for years to come.
