As its name implies, encapsulation contains your crawl space within your home’s thermal envelope, conditioning the air inside it and keeping unwanted outside air from entering. Many crawl spaces house ductwork and plumbing which should be protected from varying outdoor temperatures. Encapsulation provides a consistent atmosphere for ductwork while making your crawl space a safe and energy efficient portion of your home.
The Crawl Space Encapsulation Process
Every crawl space is treated on a case-by-case basis, but generally, encapsulation can be seen as a four-step process:
First, the experts at Total Home Performance will begin with a critical look at your current space. We’ll remove any old insulation and address any mold, pest, or standing water issues before proceeding.
Air Sealing and Crawl Space Insulation
Next, we use spray foam to seal vents, holes, and gaps around ducts and plumbing that let in outside air. Spray foam insulation is also applied to the walls for an airtight seal that both insulates and prevents moisture from entering.
A heavy duty polyethylene vapor barrier is then applied to completely cover the crawl space’s floor and walls. Sealing tape securely holds sections together, so there are no gaps to let air in or out. Our professional installers will ensure the barrier is safely and securely attached, sealing and taping around obstacles such as piers and pillars.
Crawl Space Dehumidifier Installation
Last, a dehumidifier completes the encapsulation process, ensuring the moisture in your crawl space stays at an acceptable, consistent level all year to prevent condensation buildup and inhibit mold growth.
Why Encapsulate Your Crawl Space?
The condition of your crawl space plays a critical part in your home’s comfort and indoor air quality. Left unimproved, a crawl space along Maryland’s Eastern Shore can leak humidity and odors into your living space—air that’s not only unpleasant, but also unhealthy. It will also allow heated and cooled air to escape, wasting energy and hiking up utility bills.
The team at Total Home Performance will inspect your crawl space for possible bulk water problems, combustion appliance issues, and pests before we begin making any improvements. If any of these exist, we will help you address them before encapsulation for the safest and most effective solution. Once encapsulated, your crawl space will maintain a more even temperature relative to the ground and your home, controlling humidity and improving indoor air quality while decreasing your energy consumption.
