Crawslspace Encapsulation

Free Evaluation

Crawlspace encapsulation involves three things – preventing moisture from getting into the crawlspace, preventing crawlspace moisture from getting into the house, and keeping the air inside the crawlspace conditioned.

Some signs that you might have an issue with your crawlspace …

  • Open crawlspace vents
  • Rust on metal surfaces
  • Rotting wood
  • Rodents & insects in the crawlspace
  • Dirty, damp insulation in crawlspace
  • Standing water or wet areas of the floor
  • Fiberglass insulation is on the ground
  • Musky smell or visible mold
  • Floors above the crawlspace are cold in winter months

What is “Stack Effect”?

It is driven by the “stack effect” or convection. Warm air in the upper level or attic of your home rises and is expelled through windows, vents, cracks, and gaps. Cool, damp air from the lower levels of your home – including the crawlspace – replaces that air.

Encapsulation

The crawlspace encapsulation and waterproofing process starts with placing a vapor barrier over the crawlspace floor and foundation to keep the outside air and damp air out. Non-encapsulated crawlspace can leak moisture and mold spores into your house, adversely affecting the health of the family and promoting the proliferation of mold. A crawlspace vapor barrier is a physical shield placed around a crawl space to keep moisture from escaping into other parts of your home. Crawlspace vapor barrier must cover the entire floor as well as the foundation in order to be effective.

De-Humidification & Insulation

Crawlspaces are known for moisture problems. Not only do you need to keep outside moisture from getting into your crawlspace, but you also need to make sure the air inside stays dry. In order for crawlspace encapsulation to be effective, the humidity needs to be controlled. Because of this, a proper crawlspace dehumidifier needs to be installed.

Drainage & Sump Pumps

​Drainage is an efficient way to control water penetration through foundation wall and to prevent moisture and condensation problems in crawlspaces. When water enters your crawlspace, the sump pump begins to work and pumps the water out of the crawlspace through discharge line. This is a key to removing groundwater in your crawlspace. With a good sump pump, you can keep the crawlspace free of water buildup and keep groundwater below the grade. We have all the sump pump solutions you need to deal with your wet crawlspace problems.
