The before photo shows a typical crawl space that meets local building code. However if left as is, this would create moisture, mold, rot and indoor air quality problems. The crawl is vented and has a 6 mil plastic liner, as per local code. The problem is that warm air moves moves toward colder air. Warm summer air moves through the vents into nice cool crawl space. As the warm air cools, the relative humidity rises 2.2% for every degree it cools. The result is high levels of moisture, on all surfaces, condensation on wood framing, fiberglass insulation and actual pooling on top of the plastic liner. Water below a house is bad! You can see where all the summer time puddles evaporated on top of the liner. That moisture went directly into the living space. In winter conditions the air blows right through open vents freezing floors above.
The AFTER picture shows our patented Clean Space crawl encapsulation system and properly insulated crawl space walls. The result is a dry, clean,warm crawl space year round. Reducing energy consumption, improving indoor air quality and protecting the house...
This was a NJ code compliant insulated crawl space.
The before picture shows a typical plastic liner over the earth floor in the crawl. The entire 1200 sq ft of plastic had water pooling on top of it. This was occuring due to warm air migrating towards the cool crawl space all summer long. As the warm air cools the relative humidity increases and condensation happens on every surface. This created a mold condition within less than 2 years of the crawl space being insulated with fiberglass and the liner put down.
The after picture shows our patented CLEAN SPACE crawl encapsulation system, that prevents such moisture problems in a crawl space, will help detect any plumbing leaks, improves the comfort above (warm floors in the winter) and greatly reduces energy consumption.
This customer had fiberglass insulation installed (by others) to help cold floors above.
The before picture shows the unintended side effect of not treating a crawl space problem correctly. The contractor added fiberglass insulation in the crawlsapce ceiling and a plastic liner on the floor. They didn't address moisture in the crawl. The result was, that massive condensation and water in the space all summer. Moisture+ organic materials in a cool dark space = Mold.
The After picture shows all wet comtaminated materials removed. The space was treated with Mold X cleaner. The crawl was properly sealed and insulated. This #1 sloved the cold floor problem and #2 Keeps the crawl space dry year round, keeping the humidity below levels that mold needs to grow.
This customer in the Silver Ridge development in Toms River NJ found that the crawl spaces in her new home had major concerns. The #1 concern was that there was no insulation in a fully vented crawl space. The second concern was that the moisture level in this crawl space could buckle wood floors above, develop mold, and make the house smell musty in the summer.
The best solution was to have Dave Hoh's Home Comfort & Energy Experts install a patented CLEANSPACE crawl space encapsulation system. This method resulted in a very dry, warm, clean and safe crawl space that will last throughout the life of her home.

Before picture shows a typical attic heating, cooling and duct system. The main metal trunks and plenums are not sealed and only have a 1/2" liner inside. The results are in the summer when the system is trying to deliver approx 57 degree air through ducts, that are heating up to 130 degree surface temperatures, they lose a tremendous amount of energy. In this case the system was not keeping up with demand on hotter days. The opposite is true in winter- ducts try to deliver 110 degree air through ducts that are cooling down to 30 degrees or less. The after picture shows Duct Encapsulation, the duct system is sealed and insulated with approx 3" of closed cell spray foam. This impoved the peformance of the duct system by 40% or more and now the system keeps up even on the hottest days!! If you have a modern system it makes sense to upgrade ducts, instead of installing a larger more expensive system to solve the problem.
