“We make our sales process pain free! When we come out to your home we perform an on-site inspection of your crawl space.”
As one of the most important components of the encapsulation system, the floor liner is the main line of defense against moisture penetration. We use 20 mil polyethylene film laminated together with a third layer of molten polyethylene. A heavy scrim reinforcement placed between these plies greatly enhances tear resistance and increases service life. The liner is bright white to enhance the crawl space and also makes it much easier to spot any problems such as moisture, dirt, or insects.
The wall liner is generally run along the length of the interior foundation walls, sealed at the top with an adhesive compound and then sealed to the floor liner with sealing tape. This material is also used to wrap the foundation piers or columns. Some of our competitors use the white liner for the wall; however, we use a clear liner so that a proper inspection can be performed by termite inspectors or the homeowners themselves. The material is a 6 mil clear polylaminate.
Supply Air Inducer
This device is attached to the supply side of the duct system and will introduce a small amount of conditioned air into the crawl space to help regulate the relative humidity. The supply air inducer also includes a backflow damper to keep any bad air from entering the HVAC system.
Our dehumidifier is a low temperature, Energy Star commercial grade unit. It can remove up to 50 pints of water per day.
Combustion Air In-Forcer
This device is used to introduce combustion air which is required for any appliance such as gas furnaces, or gas water heaters that do not have self supply make up air within the crawl space area.
We use Zoeller submersible sump pumps when there is no natural drain system for water to drain out in the event of a water loss.
This device has a base unit and a wireless remote unit that measures temperature and humidity. The remote sensor is placed in the crawl space and the base unit is used in the living space to monitor temperature and humidity. The homeowner can see what’s going on in the crawl space at any time without having to go underneath.
Listed last but not least, the most important component of the system is the installation itself. It doesn’t matter that all the materials are superior if the installation isn’t first class. All of our technicians are certified in the Science and Installation of Crawlspace Care systems. They have been drug tested, have had a criminal background check, a driving background check, and have passed a thorough interview process. Each one of our technicians is highly experienced and takes pride in every installation.
The Clean Envisions installation process is comprised of the following steps:
1) Sales Process
We strive to make our sales process pain-free. When we come out to your home we perform an on-site inspection. This inspection includes measuring the crawl space area, taking air/wood moisture and humidity readings, evaluation of the drain system, inspect for any signs of mildew or mold growth. After gathering all the data we prepare a very detailed proposal. For your convenience we will hand deliver, mail, or email the proposal to you.
2) Installation Process
Most installations can be performed in 2 days or less. Some installations have been completed in 1 day; it just depends on the complexity of the job. Before any work starts, we install commercial ventilator fans to discharge all air born contaminants from the crawl space while the work is taking place. The technician will first remove any wood, organic material, or debris from the crawl space. The next step is to rake down and smooth the ground level as much as possible. After that the foundation vents are sealed and a fogging machine applies a disinfectant solution before the floor/wall liner is installed. After the liners are in place, the dehumidifier is installed. Once the encapsulation system is complete the remote monitor is installed in the crawl space and the base unit is programmed to receive the temperature and humidity readings for easy viewing from the living space.
We are a certified radon measurement provider firm and can test your home for radon. Radon is a radioactive gas that can be present anywhere and can travel from your crawl space into your living space. If radon is detected in the living space, a closed crawl space system can reduce radon levels significantly.
