Homeowners dealing with a damp crawl space in older homes can easily remedy the problem with one simple project: encapsulation. Most older homes feature venting, a practice that was once thought to be ideal for countering humidity problems. Today, however, we know vented spaces do little to combat humidity. Rather, they actually cause moisture problems.
Moisture and Mold
Difficulty Heating Rooms Over Crawl Space
These problems eventually extend to the home's living areas, allowing entry to small animals, mold and musty odors.
New home building projects in humid areas (and this includes snow - the north country is quite humid) generally encapsulate any crawl space. Existing homes can also benefit from encapsulation.
Here's what R Factor will do to bring your crawl space up to code and save you heating costs.
Install a vapor barrier covering the ground and leaving no exposed areas
Install a drainage system as needed to route and remove standing water
Tightly seal the vapor barrier
Seal all vents shut
Select the most appropriate method for conditioning the space using ductwork, dehumidifier or exhaust fan.
Advanced Energy has conducted research that shows encapsulation is the best method for moisture control in humid climates. With a closed vent, the space stayed dry and humidity levels stayed low, most often below 60 percent relative humidity. When the space featured a closed vent and a vapor barrier, relative humidity was even lower, or 50 percent. On the other hand, a vented space maintained a relative humidity level consistently above 80 percent.
