As a general guideline, you should keep the humidity level in your crawl area below 55%. Depending on where you reside and what season you are in, this intensity may vary slightly. However, it’s a good idea to keep track of the humidity level all year.

Crawl space vents should be kept closed and protected from the outdoors at all times. … Open vents, first and foremost, allow moisture to enter your crawl space. This offers the ideal habitat for fungi and mildew to thrive.

Unvented. The main advantage of a vented crawl space over one that isn’t is that venting can help to reduce radon and moisture-related decay dangers by diluting the crawl space air. Providing a ventilated crawl space may also make sense in flood-prone places, such as hurricane-prone coastal zones.

In the summer, these vents allow outside air to circulate beneath the floor, preventing moisture buildup that promotes mildew and decay. The vents are closed in the winter, when the air is dryer, to prevent the pipes in the crawl space from freezing.

Installing a crawlspace dehumidifier is the best way to keep moisture levels under control. Your below-grade space will be drier, cleaner, healthier, and more energy efficient with this system.

Yes. In your crawl area, you’ll need a vapor barrier. Furthermore, a moisture barrier is the bare minimum of protection that your crawl space should have. A vapor barrier can help you prevent costly repairs.

A plastic cover or vapor barrier is essential, especially in a crawl space with a dirt floor. Moisture will travel to the surface of the earth without a vapor barrier, causing major issues in the crawl space, including fungi and perhaps structural rot. The plastic should completely cover the floor.

A drying mechanism is required in every encapsulated crawlspace. A dehumidifier is our choice (we’ll explain why in a minute), but contractors frequently use the “supply air” method to dry your crawlspace. Supply air may do a decent job of drying out the crawlspace in some homes.

A dehumidifier can help prevent fungi and mildew from growing in your crawl space, but it won’t get rid of it once it’s there. A dehumidifier, in fact, can spread fungi spores across the room and even into your home.

When properly maintained, your crawl space dehumidifier can last anywhere from 3 to 5 years.

High Humidity Fungi can only thrive in environments with a humidity level of 55 percent or above. Fungi may be controlled in your house by utilizing a dehumidifier and sufficient ventilation, which can lower the risk of fungi growth.

If not previously utilized, residents who install air conditioners, sealed crawl space systems, radiant barriers in attics, or more insulation may be eligible for a 10% federal tax credit up to $ 803-310-6330.

When you lower the temperature to 70 degrees (the average crawlspace temperature), the humidity level in the air rises to 100 percent. About 40% of the crawlspace air enters the house, according to estimates. This has a big impact on the quality of your indoor air.
