Common Problem – Crawl Space Vents and Doors
Crawlspace vents are part of the building code in most parts of the country. Unfortunately, crawl space vents are almost an anachronism in the construction business today.Crawlspace humidity control has been the focus of countless government, corporate, nonprofit, and academic research studies over the years.They all conclude that vents and poorly sealed crawl space doors allow hot, humid, moisture dense air to enter a crawl space where it condenses on the naturally cooler crawl space surfaces causing mold, wood rot, falling insulation, cupping hardwood floors, and many other expensive, annoying, and potentially dangerous issues.
Due to a phenomenon called the stack effect, that nasty crawl space air with its moisture, bacteria, mold and mildew spores, and musty, moldy odors is drawn up through the living space and exhausted through the attic. This is the nasty air that homeowners breathe in a house with an unimproved crawl space.
The Solution – Vent Covers, Flood Vents and the Everlast Door
The best methods are to seal the crawlspace vents from the inside, install vent covers, or both. Carolina Energy Conservation uses the method bust suited for the home’s esthetics, the customer’s Crawl space and the customer’s budget.Vent covers seal off the crawl space from the outside. This stops the humid airflow from outside into a home crawlspace. They are installed on the exterior of homes or if appearance is an issue, vents can be sealed from the inside of the crawl space.
Working in the “Low Country” along the South and North Carolina coast, Carolina Energy Conservation uses flood vents whenever the building code requires them. Flood Vents protect houses and buildings in floodplains by preventing hydrostatic pressure buildup that can destroy walls and foundations. This mitigation technique is referred to as Wet Floodproofing.
