Crawl Space Encapsulation – Understanding the Basics
Crawl space encapsulation….sounds super complex and scary right? No worries! That’s why we are here.
When it comes to crawl space encapsulation, there are a lot of specifics…but we won’t dive into that right now. The sole purpose of this blog is to provide you with the basics.
So, what is crawl space encapsulation? Well….crawl space encapsulation is the SOLUTION for all of your crawl space problems. If you have open crawl space vents, high electric bills, mold in your crawl space or wet crawl space insulation then 10 times out of 10 you need crawl space encapsulation.
All of the problems listed above are due to too much moisture accumulating in your dirt crawl space. Crawl space encapsulation eliminates the negative effects of dirt crawl spaces using 4 steps. *Note – not all crawl spaces need these solutions, so it’s best to have a professional come out to your home to take a look.
Step 1 – Sump Pump
Step 1 of crawl space encapsulation involves addressing the presence of standing ground water and leakage within your crawl space through the installation of a sump pump. If you don’t know if your crawl space has a leakage problem then you should be do a careful inspection to look for signs of water pooling. Using a good light source look for waterlines (rings of soil and slit) on the wall or patterns of erosion in the soil where the water made its way from its entry point. If you notice the presence of water then you need to have your crawl space encapsulated starting first with a Sump pump.
Step 2 – Vapor Barrier Liner
Step 2 of crawl space encapsulation involves isolating the house from the earth by installing a CrawlSeal vapor barrier liner. Vapor barrier liners are available in varied sizes of thickness 6 mil, 10 mil, 12 mil, 15 mil and 20 mil. However, a 20 mil vapor barrier liner is preferred by industry professionals due to its durability and other added benefits resulting in 15% energy cost savings.
Step 3 – Vent Covers
Step 3 of crawl space encapsulation involves sealing your crawl space vents and other outside air leaks. Because steps 1 and 2 eliminated the standing water within your crawl space you want to make sure you seal your vents using CrawlSeal vent covers to keep out uncontrolled outside air.
Step 4 – Dehumidifier
Step 4 of crawl space encapsulation involves “conditioning” or dehumidifying your crawl space. In steps 1-3 we have already sealed off the earth and sealed air leaks to the outside, but in order to rid your crawl space of any other circulating air moisture a crawl space dehumidifier needs to be installed. Plus, the JES Dehumidifier dehumidifier system is 5 Star Energy rated.
Crawl Space Encapsulation – Extras
In addition to sump pumps, vapor barrier liners, vent covers and dehumidifiers your crawl space may need additional components to be COMPLETELY encapsulated.
The Turtl is your crawl space encapsulation solution addition if the entrance to your current crawl space is below the ground outside. A large majority of crawl space entrances located below ground leak air and collect water and debris. They are also very rusty and a danger to your safety and the safety of others if someone accidentally falls into it. The Turtl is made out of strong plastic, so it will never rust or corrode and it is secure and lockable.
JES sealed our crawl space. It was necessary due to my son’s allergies. They performed the work in an efficient and timely manner. The product is good as I have had no problems so far. I would use JES again.
