What is the Purpose of Crawl Space Encapsulation
Updated: Mar 3
Are you thinking about having your crawl space encapsulated? This process creates a dry buffer between the floor of the crawl space, its walls and the floors above to prevent moisture retention and create a more stable foundation. As a result, you improve energy efficiency and save money.
Like other home improvements, crawl space encapsulation is optional - it is not a requirement. But if you want to get rid of moisture, pests, mold and foul odors, encapsulation is a necessity. Let’s learn more about the purpose of encapsulating your crawl space, the benefits to expect and the steps to take.
Why Do Homeowners Encapsulate Their Crawl Spaces?
By nature, crawl spaces are dark and somewhat musty. But your crawl space should still be dry. If this space feels damp, or there are noticeable signs of water, you have a problem. Dampness sets the stage for mold and mildew growth, musty smells, pests, water damage and structural damage. All of these issues can be expensive to fix, and they can affect your health.
There are a number of crawl space waterproofing options, and encapsulation is one of them. It’s the most effective waterproofing solution, and it involves a contractor covering your walls and floors with a thick plastic vapor barrier. This barrier is what locks out moisture from the ground and air from the outdoors. Once the 20 millimeter thick heavy duty polypropylene vapor barrier is in place, dehumidifiers are installed that help to control the humidity in the crawl space.
When a crawl space is encapsulated, you will see the following benefits:
Controlled humidity. To stop humidity from entering the crawl space, you need the proper insulation, which you will get from the vapor barrier.
Mold growth prevention. Mold and mildew thrive in dark, damp places. Eliminating moisture and keeping the air in constant circulation will prevent mold from growing.
Fewer pests. Many pests (roaches, beetles, rats) benefit from a damp and humid living environment, as this allows them to catch food and reproduce. Encapsulation keeps the pests out and stops infestations.
Protected structural integrity. Chronic moisture buildup can weaken load-bearing piers and foundations, comprising your home’s structural integrity. Encapsulation prevents this from happening.
Improved indoor comfort. Crawl space encapsulation will make your home feel more comfortable by controlling humidity and maintaining good indoor air quality. The air feels better because allergens, dust and other pathogens are blocked by the barrier.
Decreased energy costs. With improved insulation and better efficiency, your HVAC system doesn’t have to work as hard to keep your home comfortable. This reduces your energy bills.
