The crawl space in most homes acts as little more than a space to store a few boxes and other odds and ends. The problem with most crawl spaces is that they’re too small and offer little in the way of height for them to be functional living spaces.

Crawlspaces are notorious for trapping moisture and being breeding grounds for mold and pests, especially if the crawl space is little more than a dirt floor and uninsulated walls. Moist air, mold spores, and a foul smell from your crawl space can be circulated through your home, making for unhealthy living conditions and high energy bills. Insulating your crawl space is the best way to prevent moisture buildup and conserve energy. Here are some tips for insulating your crawl space.

Spray Foam

Spray foam is by far the fastest and most efficient form of crawl space insulation, but it’s also one of the most expensive. Another downside to spray foam is that it’s not environmentally friendly unless you opt for eco-friendly spray foam.

The upside of spray foam is that it has a high R-value and can be applied very quickly. Spray foam also provides an excellent seal against moisture and air and can fill the smallest of holes, which helps to reduce pest infiltration into your crawlspace. According to the experts at 58 Foundations, it’s a good option if you only have about 2-inches of depth to fill.

Insulate the Walls

If the walls in your crawlspace are uninsulated, cold, moist air will enter your home through the floor and walls. Because of this, it’s important that your crawl space be insulated against variations in temperatures. Effective insulation of your crawlspace means insulating the walls and ceilings of your crawlspace.

Install an Air and Vapor Barrier

Most crawl spaces have dirt floors, which creates a lot of humidity as moisture evaporates from the ground. If you don’t do any other insulating in your crawlspace, you should add a class A poly-woven vapor barrier over the dirt floor to reduce the moisture supply.

While you can do this job DIY, you should use a professional company to ensure proper sealing of the barrier around walls and joints. Even if you don’t seal the barrier with tape or sealant, you will reduce the amount of moisture in the air simply by covering all or most of the floor.

Seal all Vent Openings

The vents in and around your crawlspace allow moisture to enter the space. Moist air will condense on wood and framing, which promotes the growth of mold and mildew and can create a breeding ground for pests. When the weather is cold, the cold air will enter the crawl space and make the floors in your home cold to the touch.

Sealing the vents in and around your crawl space will help avoid moisture issues and make the inside of your home warmer and healthier. By keeping cold, damp air from entering your home, you can lower your thermostat, which can help lower your heating bill.

The crawlspace beneath your home doesn’t have to make your home uncomfortable and unhealthy. With proper crawl space insulation and dehumidification, you can effectively make your crawlspace a safe place for storage and a healthy environment for your home.
