The Coastal Dry Home Solution to Eliminating Your Moisture Woes and Maintaining a Healthy Indoor Air Environment
Our unique Moisture Control & Ventilation System (MCV) will:
> EXPEL moisture, gases, toxins, and pollutants > REPLENISH the polluted, damp air with healthy, dry air > VENTILATE the entire house, drying out the structure Unlike a conventional dehumidifier which does not exchange the air, ventilate the crawl space or basement and is costly to operate, Coastal Dry Home's Solution will provide a healthier, drier and more comfortable home at a fraction of the cost. Our quiet yet powerful system draws in moist, contaminated indoor pollutants, and expels them safely from the home. This unhealthy air is then replaced with a flow of drier, fresher air drawn downward from the upper levels. Replenishment air comes from the outdoors and enters the home naturally via windows, doors, and other openings. In essence, the MCV not only provides the home with much needed healthier outdoor air; it creates crucial ventilation within the home which inhibits the growth of molds and reduces moisture related problems. |

Step 1 - Expel

The moisture seeping in through the foundation and generated from normal activities contribute to a heavy moisture-laden air mass at the floor level of the crawl space or basement. It is also the coldest part of the house, thereby resulting in the highest relative humidity. This damp air in these poorly ventilated areas stagnates and creates an environment conducive to mold growth and structural damage. The air in the lower levels is also saturated with contaminants from combustion appliances, chemicals, gases, radon and vapor toxins that permeate in from underneath. Due to the Stack Effect this moist, pollutant-rich air infiltrates the living space above with dramatic adverse effects on Indoor Air Quality, our comfort and our health.
Effective expulsion and mitigation of moisture and toxins from the lowest level is essential to creating a healthy living environment and structure.
When the MCV system from Coastal Dry Home is installed and operating, this stagnant, damp, contaminated air is drawn to the bottom vents of the unit by a powerful, yet quiet, ventilation fan. This is the distinct uniqueness and effectiveness of our Solution, in that it is directing the effort to the source of the problem and where it persists. When the surface moisture is drawn off, the moisture within the walls tends to come to the exterior surface and is also expelled, resulting in structural drying.

Step 2 - Replenish

Once the moist air is drawn into the powerful, quiet patented MCV system, it is then expelled to outside of the house through a 6" dedicated duct. This flushed-out, contaminated air is then replaced with a flow of relatively drier, warmer and fresher air drawn downward from the upper levels. The warmer air will lower the relative humidity and reduce the condensation on the crawl space or basement surface.
The interior upstairs air is then replaced with cleaner, fresher outdoor air entering the home naturally via windows, doors, and cracks.

Step 3 - Ventilate

Coastal Dry Home's MCV system is automatically controlled by an adjustable humidistat that regulates the flow of air. When the desired level of humidity is achieved, the fan will reduce speed and resume a higher speed if humidity level increases. At a high rate, which is only at peak times, it will be equivalent to two bathroom fans. In maintenance mode it's a fraction of that, yet still sufficient enough to meet the minimum air exchange required.
The direct effect of the air being expelled and the flow of air downward creates an air exchange throughout. As the moisture is drawn off the surface, the moisture absorbed in the walls and floor comes to the surface and is then expelled, reducing structural damage.
