Moisture Control
MOISTURE PROBLEMS CAN LEAD TO BIGGER PROBLEMS.
Sources of moisture in your crawl space are primarily from evaporation of water from the soil, diffusion through foundation walls, and humid air entering the crawl space. Moisture problems also develop under a home when there is improper grading and drainage. These types of problems can lead to high moisture content in the wood framing members in the floor, resulting in rot, wood destroying fungus and a conducive environment for termite infestations. There are several methods to correct the high humidity levels and/or standing water in a crawl space. Some of those methods include:
Soil covers
A polyethylene barrier is installed across the crawl space floor to prevent soil moisture from evaporating into the crawl space.
Automatic Vents
Automatic vents are installed where the existing non-automatic vents are located in the building’s foundation. These vents open and close automatically based on the outside temperate. During winter months, the vents close to retain heat in the crawl space and during summer months, the vents open to allow air flow throughout the crawl space.
Power vents
The Power Temp-vent is similar to the Automatic Vents but also have a fan to increase airflow. These vents are installed where the existing non-automatic vents are located in the building's foundation. When on, the fan will pump air out of designated air spaces. This is an ideal solution for moist, damp, humid crawl spaces which need some type of extra ventilation. The vents are fitted with a humidistat to control the operation of the vent.
Sump Pumps
Sump Pumps are recommended when there is a constant standing water problem in the crawl space. The pump is placed in the lowest area of the crawl space and the water is then pumped out of the crawl space.
Dehumidifiers
Dehumidifiers are an electrical appliance for removing excess humidity from the air in the crawl space. Since the dehumidifier is removing the humidity within the crawl space, the vents are sealed to prevent outside humidity from entering the crawl space. A vapor barrier is also installed to prevent soil moisture from evaporating into the crawl space. A Certified Electrician will hard-wire the dehumidifier in your crawl space. It is recommended that a representative from our company inspect your dehumidifier annually. During this annual inspection, all routine maintenance of the dehumidifier is performed to ensure that the system continues to work properly.
