Crawl Space Dehumidification


Who Cares What Is Going On In Their Crawlspace? 
The correct answer is EVERYONE SHOULD.


A typical crawl space has a dirt or cement floor with block walls and some ventilation to the outside. The thinking was that the condition of the crawlspace should be similar to the outdoor conditions, just like in your attic. Turns out, science has a different answer. The exchange of air from your attic to your living space is minimal, thanks to roof ventilation and attic insulation, a properly roofed home will have an upward draw. If you’re on a crawl space, this means you are drawing air up from the crawl space in to the living space, at a rate of up to 50%. 

What kind of air quality do you have down there? Ventilation doesn’t equal air exchange, so even a code compliant home could have conditions in the crawl space that are ideal for mold or fungus.

Additionally, crawl spaces are magnets for rodents and pests, and can trap allergens from the outside air. In North Carolina, summertime humidity averages between 80%-90%. Mold growth starts at 70% and can be enhanced by heat – yuck! All that dirty, contaminated air could be coming into your house! Let us help with that. 

We can solve your crawlspace issues by installing a continuous vapor barrier with all seams sealed, insulating your crawlspace doors, permanently closing off and insulating all foundation vents and a installing a quality dehumidifier.
