Crawl Space Vent Covers and Doors

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.

Smart Vent Products, Inc. was born in 1997 to create a flood vent that would comply with the Federal Emergency Management Agency (FEMA), National Flood Insurance Program (NFIP), and all National and State Construction Codes. Since 1986, flood vents have been a requirement for enclosed spaces below the Base Flood Elevation (BFE) but no one had stepped up to evaluate what was available to meet the requirements. At the time, the only available solution to relieve hydrostatic pressure was a foundation air vent. These air vents had some issues, including louvers, grills, screens, and other covers that impeded the flow of floodwater and most importantly clogged the vent with debris, rendering them useless during a flood. Flood Vent came up with a solution. They produced the first ever engineered flood vents and developed the performance testing standards that are still utilized in the flood venting industry today.

 

Carolina Energy Conservation takes very seriously the responsibility of protecting what is most likely your largest investment. Our recommended flood vents have been performance tested through the ICC-ES and through more than 15 years of floods and hurricanes with remarkable results. We are proud to use a company that manufactures, operates, and is owned in the United States of America. They are committed to providing the best products in the flood control industry.

The vents and vapor barrier work together to seal a crawl space. Using one without the other is a recipe for disaster.Give us a call for a free, no obligation crawl space assessment and discover what vent option are available and required for your home.
