Crawl Space Encapsulation Santa Rosa

Crawl Space Encapsulation Santa Rosa Each of your home’s systems plays a key role in the overall health of your house. Since your home’s systems rely on each other, a problem in your crawl space will eventually spread to other areas – causing major damage. At Thrasher, we solve those problems with options for crawl space repair, crawl space encapsulation, vapor barrier, and crawl space insulation. Crawl space repair is the perfect solution to help you save money on utility bills, avoid unnecessary repairs, and create a healthy living space in your home. With crawl space encapsulation, you will gain valuable space for storage and protect your home once we have sealed your crawl space with a durable vapor barrier. The crawl space encapsulation treatment totally separates and protects the crawl space interior from outdoor conditions, keeping the space clean and dry. Whether your crawl space is wet and moist, needs winterization, or has foundation repair issues, our team will conduct a complete in-home inspection, professional consultation, and free crawl space repair quote that details the perfect solution.




  • Upfront Investment
  • According to Home Advisor, the average homeowner can expect to pay $5,500 to install this system.
  • Cost of Foundation Wall Insulation
  • If you get an estimate for encapsulation your contractor might suggest installing foundation wall insulation to help you benefit more. The product is usually composed of spray foam and costs between 50 cents to $2 per board foot. Batting prices are either $3 per roll or $300 for a larger area. The insulation is R-value foam board based on local building codes.
  • Additional Maintenance
  • After your crawl space encapsulation system has been installed you will need additional maintenance and inspections throughout the year. The cost of maintenance will be dependent on the amount of features you went with during the installation process. If you live in a geographic region that doesn’t see a lot of rain or moisture, unlike Charlotte, NC, then the sealing advantages of this product might not give you the return on your investment that you need.
  • Might Need To Upgrade Your HVAC System

Crawl space encapsulation will limit the amount of air movement throughout the home. This increases the efficiency of your home but at the same time might not allow enough oxygen for an older combustion-based furnace or heater to run normally. Of course, this means you may need to upgrade your HVAC system to ensure the temperature levels in your home stay comfortable and consistent.

Crawl Space Encapsulation Vs Vapor Barrier

The difference between a vapor barrier and encapsulation in a crawl space comes down to thickness and a sealed interior.


The purpose of a vapor barrier is to reduce ground water from evaporating in your crawl space. To counteract that a thin sheet usually 4 to 6 millimeters thick covers the floor. The vapor barrier is not a sealed system and typically stops just short of the interior walls.


Because of this some water can still bypass the vapor barrier and enter the crawl space. A more comprehensive and expensive approach would be to get your crawl space encapsulated to better guarantee no more moisture.


Once the crawl space has been prepped and all the water removed, a thicker plastic lining is installed and all vents, holes and cracks where air can enter is completely sealed. This thicker plastic is usually 12 to 20 millimeters thick. It also has a polyester-cored reinforcement which is more durable than the vapor barrier. Most importantly though all the seams are sealed and the liner is fasted to the floor and all the way up the walls and columns. This completes the encapsulation.
