During the summer, the hot air enters the cool crawl space, and as that outside air cools, the relative humidity levels increase well above the 70% RH necessary for mold to grow; the 90% RH necessary for wood to rot and condensation forms all over ducts, framing and insulation. Insects and other pests love dark and damp places, and they move right in.
This is not an isolated problem. Nearly all homes with dirt-floored, vented crawl spaces have mold, pests and higher heating and cooling costs. Humid air is harder to cool in the summer, and during the winter the cold air entering the house through the vents make the floors cold, and the entire house feels colder. As a result, the furnace works harder to keep the home comfortable.
If fixing your crawl space can make the home cleaner, healthier and more energy efficient, why wouldn't everyone fix their crawl spaces right now?
Most of the time, the cost of the repair is a big deterrent. Yet this video shows that fixing your crawl space is not only a good idea, it is an excellent investment that, on average, will pay for itself in about 8 years, in energy savings alone!
In 8 years you will not only have all your money back, but you will have enjoyed a more comfortable and healthier home. And you will go on enjoying the comfort and savings for many years to come!
If you don't fix it now, you will be overpaying for heating and cooling every month and in 8 years you would have spent the full amount that the repair would have cost while living in discomfort.
In terms of environmental impact, over the course of 8 years, an encapsulated crawl space can help save 400,000 cubic feet of natural gas (or oil) and prevent 26 tons of carbon dioxide (CO2) from being released into the atmosphere from your home.
We all like to invest money wisely, save energy and live comfortably. When given the chance, we all like to help save natural resources and help the planet. Fixing your crawl space is a one-time investment that will help you accomplish all of these things -- and after 8 years, it is free!
