Step 3: Vent Covers

Does your crawl space have vents? If you currently have crawl space vents in your home, you’re going to need to install a crawl space vent cover on each of those vents. In the past, many people believed that “airing a crawl space out” was the best way to avoid crawl space moisture. However, nowadays, experts believe this venting process actually allows more moisture to collect in the crawl space because of the math that goes along with relative humidity.

Installing airtight vent covers can fix this additional moisture problem. A vent cover is very easy to install, overall; all you have to do is fasten the vent cover on the vent and you’ll be protected from extra moisture that may come in from the vent. Vent covers can also protect you against pests that might enter through a vent and water that might come in during rain or floods. Overall, covering your crawl space vents is absolutely a better choice than leaving them open.
