Crawl space vents are old technology. They are worse than benign; they can damage your home and taint the indoor air your family breathes. Builders originally assumed that venting crawl spaces would dry the air. But now we know that they do the polar opposite. Crawl space vents bring humid, damp, or freezing cold air inside, and then up into your home’s living spaces.
Crawl Space Solutions by Cowleys highly recommends, based on modern building science, that you seal off your crawl space vents. This is one of the most important parts of our comprehensive crawl space repair program. It will keep outside air away, along with all the moisture, pests, winter cold, and summer heat it brings with it.
Ground-level vent openings in your home are also an invitation for a wide variety of pests and wood-destroying insects such as termites, carpenter ants, and wood-eating beetles. Wood destroying insects are attracted to moldy, rotting wood, and open vents easily allow them into your structure. Stay warmer and drier with a sealed crawl space and keep the rain and damp air out.
When you seal your crawl space, you seal your problems.
