The crawl space tends to be a neglected part of many homes. It is seldom seen and rarely used. However, maintenance of the crawl space is crucial to the overall energy efficiency of your home. Having a properly maintained crawl space can save energy in the home – during colder months, drafts of cold air will lower the temperature of your home and in the warmer months, heat will collect and cause the home to lose any cold air that was generated from within.
Insulate the access door.
It’s very important to keep the access door to the crawl space insulated and airtight at all access points. Doing so will regulate the air temperature in the crawl space and maintain a better climate throughout the home. If you are using a plywood door cover the inside with a firm insulation board to help control drafts.
Inspect and clean the interior.
Once all external sources of moisture are eliminated, proceed to inspecting the crawl space itself. Crawl spaces with dirt floors can lead to problems from humidity, so consider sealing them with a moisture retardant such as polyethylene. Regular cleaning will help keep the space dry and moisture-free, though it may seem like a tedious task.
Ventilate and block out rodents.
Another important step in maintaining a functioning crawl space is keeping it clean. While inspecting, make sure that any potential entry points for rodents or pests are blocked off. Though a small crack or seam may appear tiny, it is probably big enough for mice or roaches to enter.
Control climate with a dehumidifier.
Add a dehumidifier unit to your crawl space to help with energy efficiency. There are several different types on the market, so do thorough research on the best option for your home. Think about the average temperatures where you are and the location of the crawl space. The dehumidifier will ensure that the air within the crawl space does not reach extremes, but stays at a constant and comfortable temperature. Doing this will also help prevent mold or mildew from growing on any surfaces.
