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.
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.
