Crawl Space Encapsulation Before & After Photos

This homeowner in Rumson, NJ decided it was time to get rid of all the moisture in his crawl space and utilize it for storage, but he had no idea what to do. So he called Cowleys and we were sent out to insect and encapsulate.

After a thorough inspection, we noticed that the crawl space was in disarray and the insulation was dirty and soaked with moisture. Using our hygrometer, we noticed the humidity levels were extremely high. Fortunately, no mold had developed. Crawl spaces can spell trouble. As a subterranean space, they are often the primary point of entry for water and moisture, and they are the root cause of many home problems – including problems that affect your family’s health.

After speaking with the homeowner and discussing options, we went to work. First, we removed all the debris and contaminated insulation and then leveled the ground for proper draining. Afterward, we installed a drainage matting, which is a dimpled plastic mat that allows excess moisture to work its way over to the new sump pump we installed. We then filled the outside of the hole of the sump pump area with stones which will allow water to filter downward.

Next, we installed a vapor barrier which is a 20-mil 7-ply sandwich of high and low-density polyethylene with a polyester-cord reinforcement. It cannot tear, is extremely durable, and is treated with an antimicrobial finish that protects against mold and mildew growth. Once the vapor barrier was down, we installed SilverGlo™ along the walls of the crawl space. SilverGlo™ is a durable and waterproof rigid foam insulation that seals the walls from outside moisture and humidity.

Lastly, we installed a Sani-Dry Sedona dehumidifier. This heavy-duty, commercial-grade dehumidifier directs the extracted water pulled out of the air directly into the sump pump. Now the crawl space will no longer have any issues with high humidity levels, mold or mildew growth, and will create a healthy environment for the family.

This homeowner in Rumson, NJ was tired of having an excessive amount of moisture in his crawl space, so he called our office to encapsulate it. Excessive moisture in your crawl space can have a major impact on your family’s health. In fact, 50% of the air in your home comes up through the crawl space — which means that moisture and mold can seep into your home, where you're breathing it in. After surveying the crawl space, we noticed that the homeowner had a dirt floor crawl space. Dirt floor crawl spaces attract and absorb moisture. When the dirt dries, the moisture from the dirt ground evaporates up into the crawl space, which causes humidity levels to rise in your home. After a thorough inspection, we determined that this was the cause of the moisture build-up in the crawl space.  

First, we leveled the ground for proper draining and installed drainage matting. This material is a dimpled plastic mat that allows all excess moisture to work its way over to the sump pump. Once we finished, we installed a vapor barrier which is a heavy-duty, 20-mil 7-ply sandwich of high and low-density polyethylene with a polyester-cord reinforcement. It cannot tear and is extremely durable. The vapor barrier is also treated with an antimicrobial to prevent mold and is installed over the foundation walls and floor to create a continuous air and moisture barrier.

Next, we installed SilverGlo™ on the walls of the crawl space. SilverGlo™ is a waterproof foam insulation that seals the walls from outside moisture and humidity. Lastly, we installed a Sani-Dry Sedona commercial-grade dehumidifier to control the humidity levels. The Sedona directs the extracted water pulled out of the air directly into the sump pump.
