Crawl Space Encapsulation


Crawl spaces in general are relatively unhealthy as they are breeding grounds for mice, snakes, and other pests with high humidity levels and outgassing dirt. Roughly 60% of the air you breathe inside your home on a crawl space is circulating through the crawl space. Once a crawl space has been encapsulated it will help protect you control musty smells, high humidity levels that lead to mold and mildew, and will greatly improve the breathing health inside the home.

If the crawl space is flooding a drainage system with a sump pump will first be installed to ensure all ground water is properly addressed below the liner. Once our drainage system is in place, any debris will be removed from the area and the vents will be sealed off. At this point we are now ready to start the installation of the crawl space encapsulation liner which varies in thickness from 10-mil to 20-mil typically.

Frequently Asked Questions

Crawl space encapsulation is the process of sealing and waterproofing a crawl space. The process begins with perimeter drainage and a sump system to ensure that outside water cannot flood the crawl space. Once the drainage is installed a vapor barrier is installed and sealed to the foundation walls, columns, and then the floor. Vents in the crawl space are sealed airtight to prevent outside air from entering the crawl space. Lastly a dehumidifier is typically installed to control humidity levels and ensure a clean, healthy environment.

Costs can greatly vary based on the size, height, and accessibility of the crawl space, however typical pricing starts around $5,000 and can go up to $15,000.

A healthy home starts with a good foundation. Roughly 60% of the air you breathe in your home comes up from below, this is known as the stack effect. If your home sits on a crawl space this means air is filtering through the crawl into the home. Most homes on a crawl space have HVAC systems down below. To ensure a clean and safe home for your family you must keep the crawl space clean and dry.
