The benefits of encapsulating your crawl space include moisture control keeps allergens out eliminates dust mites and provides you with clean air coming into your home. Did you know that half of the air on the first floor of your home comes from underneath your house? Encapsulate and breathe cleaner air.

When it comes to insulating crawl spaces, John's has you covered with our advanced, closed-cell Spray Foam Insulation, which is the only type of insulation that qualifies as an air, thermal, moisture, and vapor barrier, and far surpasses traditional fiberglass insulation in both longevity and effectiveness. For many decades, traditional fiberglass insulation has been installed beneath the subfloor of homes to lessen heat loss through the interior flooring. The concept of fiberglass insulation makes sense, and it does help homes retain heat, but this type of insulation is incredibly vulnerable to damage from countless entities: moisture, rodents, bacteria, air - just to name a few. When fiberglass insulation comes in contact with moisture, it falls apart and rapidly loses all insulating capabilities. The material is made to exisit in a six sided box, making it ineffective in the crawl space. As fiberglass insulation falls apart, it lands on top of the vapor barrier beneath the subfloor, and makes excellent material for rodents to use to make their nests. Again, traditional insulation makes sense, but it will inevitably be damaged, fall apart, and create a welcoming area for rodents to breed and infest - creating toxins in the air, along with a nasty, heavy odor within the crawl space. The main concern with a rodent infestation, is the terribly negative effects that those toxins have on the air quality within the overhead home. As 40% of interior air comes from below, it is absolutely imperative that crawl spaces are free of toxicity. With traditional fiberglass insulation, a healthy crawl space is impossible to sustain, this is where our Spray Foam insulation comes in. Thanks to the experts in the crawl space repair industry, Spray Foam insulation was invented and perfected, and has been proven time and time again - over more than a decade - to offer excellent insulation that does not fall apart, and provides a perfect barrier against vapors, thermals, moisture, and air. When Spray Foam insulation is installed by the Spray Foam Specialists here at John's, it will last the life of the home, and when paired with a crawl space Encapsulation, it has the potential to save homeowners up to 40% per year on heating and cooling costs. Spray Foam is sprayed directly onto foundation walls with meticulous precision, until every crevice and void is filled, creating a perfect, air-tight seal. Because Spray Foam is highly effective at creating a tight seal, it is the best choice of insulation to use inside of an Encapsulated crawl space which is sealed entirely to protect the home. John's makes it easy to upgrade traditional fiberglass subfloor insulation.

Customers were curious about the benefits of crawl space encapsulation 

The homeowner was having an inspection done. The inspector suggested they get their crawlspace sealed due to the fiberglass insulation falling to bits. 

This homes crawlspace had humidity issues and a very muddy floor, which made keeping a 6 Mil vapor barrier in place, very difficult. To address the homes needs we did a full encapsulation.
