What is Crawl Space Encapsulation?

Many older homes will have a crawl space which is used to promote air circulation through the home from a vent and also used as an access point to get to plumbing, duct, wiring work, and other maintenance/repair needs. Crawl spaces usually are not insulated and humidity can be a problem. Moisture from the damp soil (crawl space with no concrete floor) along with a foundation wall leak and humidity accumulation from the crawl space vents, can create a breeding ground for mold and mildew on any surface including hardwood floors and cardboard boxes.

Crawl Space Encapsulation seals the space by installing an airtight vapor barrier system that prevents air passage from the crawlspace to your home. Doing this will have imediate benefits to the health of your home which includes:

  • Effects on the cooling and heating in your home as air movement has been stopped
  • Reduce the risks of mold and mildew growth under your home
  • Reducing strain on your HVAC equipment
  • Reduce the price of your energy bills

A dehumidifier can also help significantly decrease moisture levels and reduce any risk of mold, mildew, termites, odor, allergies, dust mites, and other poor indoor air quality issues.
