Crawl Space Moisture Control

Why are crawl spaces a breeding ground for mold issues? Because of the high moisture and humidity in crawl spaces. Think about the location of the crawl space. It sits underneath your home right on top of the earth. The dirt and soil from the earth contain moisture. And this moisture forms very easily in confined areas. Homes in  Southeastern states report having this issue more often. The EPA says, “The best way to control mold growth is to control moisture.” www.epa.gov/mold So what are some ways to control moisture in the crawl space?

Crawl Space Moisture Control Tips

Crawl Space Maintenance

First off it’s essential to inspect the crawlspace for damage and quickly repair it. Check your crawl space for holes or cracks that small critters, cockroaches, and mice use to enter this space. ensure there are no entry or exit points within the crawl space. Seal holes using foam insulation, caulking, or wood. Similarly, check out any leaks that may be sending drips of water into your crawl space. Be sure to fix any issues quickly. Cleaning the crawl space regularly will help.  

Do I need a Dehumidifier? - Yes 

Moisture can go through the roof and cause problems during hot and humid months. Don’t let it build up. Get a dehumidifier to collect the excess moisture in the air and leave your space nice and dry. A dehumidifier will regulate humidity levels in your crawl space. The energy-efficient, self-draining models are the best and widely recommended.

Vapor Barriers A Must 

Sealing your crawl space is important if it has exposed dirt floors. Exposed dirt floors cause ground moisture to seep into your home, which increases humidity levels. Vapor barriers will be an effective solution and prevent moisture from entering your crawl space. When done properly, encapsulation can reduce moisture levels in your crawl space by 50% and keep it dry for many years.

Insulate your crawl space

You will need to insulate the crawl space after the vapor barrier is installed. Rigid panels made of expanded polystyrene foam are highly recommended. This type of insulation is more reliable and won’t fail or harbor mold or pests when wet. Insulation creates a tight seal that keeps air out while protecting the crawl space from moisture and mold growth. Proper insulation can affect conditions inside your home, and will nicely, lower your energy costs. Crawl space insulation helps to enhance your home’s energy efficiency.

Vents need to be Covered

Make sure any vents are concealed with airtight covers to keep nuisances out. Uncovered vents allow outside air, water, and pests to easily access your home, which leads to problems like flooding, moisture, damage to your structural supports, and more. Vents to the crawl space need to be covered.

Install a sump pump

As part of your flood prevention initiative, have a sump pump installed at the lowest section of the crawl space. You never know when it could flood. In the unlikely event that large amounts of water get in, like after a heavy downpour or a burst pipe, the sump pump will remove the water before it collects and causes damage.

Be Vigilant

By giving regular time and attention to the prevention of moisture in the crawl space you will be able to avoid Unnecessary expenses to this part of your home.
