Moisture Control Systems

The indoor air quality levels in the basement or first floor of a slab home are saturated with contaminants from combustion appliances, chemicals, gases, radon and vapor toxins that permeate in from underneath. Mold spores breed in damp carpets that touch concrete floors and never dry out.

Our Home Moisture Control systems are not like a dehumidifiers, that do not exchange the air or ventilate the basement. They are not costly to run, either. Once installed into your basement, they will provide a healthier, drier, and more comfortable home without the hassles and expense of a dehumidifier. All homes benefit from this effective home moisture control system. If you have a finished basement with a family room, playroom, or office, this system is a must for you!

How It Works. 

The system draws in moist, contaminated indoor pollutants like mold, mildew and soil gases that leak through basement foundations and expels them safely from the home. This unhealthy air is then replaced with a flow of fresh air drawn downward from the upper levels that is considerably drier than the air in the lower levels or basement. Replenishment air also comes from outside, entering the home naturally through openings like windows and doors. The down-draft effect provides a constant flow of fresh air.



Step One- Expel

Moisture and condensation seeping in through the foundation and generated from normal activities, like a clothes dryer in the basement, contribute to a heavy moisture-laden air mass at the floor level of the basement. And, because cold air sinks, the bottom six inches of the basement floor is where the highest humidity is in the house. In poorly ventilated areas, the damp air stagnates and creates a perfect environment for mold colonization, structural damage and discomfort.

Once installed, your Moisture Control System will draw in stagnant, damp, contaminated air to the bottom vents of the unit by a powerful, yet quiet, ventilation fan. When the surface moisture is drawn off, the moisture within the walls migrates to the exterior surface and is also expelled, resulting in a process that is drying out the wood, sheetrock, and furnishings that are in a damp basement.

Step Two- Replenish


Once the moist air is drawn into the powerful, quiet system, it is then expelled to outside of the house through a 6" dedicated duct, similar to a dryer vent. This flushed-out, contaminated air is then replaced with a flow of relatively drier, warmer and fresher air drawn downward from the upper levels. Because this air is warmer it will also work to lower the relative humidity and dry out the condensation on the basement surfaces.
The interior upstairs air is then replaced with cleaner, fresher outdoor air entering the home naturally via windows, doors, and cracks.

Step Three- Ventilate



Your new Home Moisture Control system is controlled by an adjustable humidistat that automatically regulates the flow of air. When the desired level of humidity is achieved, the fan will reduce speed and in the same way resume a higher speed if the humidity level increases. At it’s peak operation speed, it will be using only the power equivalent to two bathroom fans. In maintenance mode it's a fraction of that, just enough to meet the minimum air exchange required for healthy, dry air.
