Crawlspace Encapsulation

The Crawl Space Encapsulation Program is designed to close any foundation openings and encapsulate the space with a water vapor barrier and then conditioning the space using a dehumidifying system. It provides an effective more comprehensive method of controlling wood decay.

Encapsulation is recommended if your crawl space suffers from poor moisture management such as:

  • Moisture damage in the crawl space or living area;
  • Musty odors in the living area;
  • Condensation (“sweating”) on air conditioning ductwork or equipment;
  • Condensation on insulation, water pipes or truss plates in the crawl space;
  • Buckled hardwood floors;
  • High humidity in the living area;
  • Insect infestations;
  • Rot in wooden framing members.

As much as 50% of the air you breathe on the first floor of your home comes from your crawl space.  Damp, musty air constantly drawn into your home from your crawl space contributes to poor indoor air quality.

What do you need to do to prepare for an encapsulation job?

Our equipment only requires a standard GFI outlet.  If there is no outlet located in the crawl space then one will have to be installed by an electrician preferably before the encapsulation begins (This is not included in the pricing).

How long does an encapsulation job take to complete?

Most encapsulation services take 2-4 days depending on the scope of service.
