A dirt crawl space under a home can lead to unending problems. The earth has very high humidity in the soil. This water vapor moves easily into the crawl space and upwards into the house environment. Mold thrives and reproduces by producing airborne spores by the millions and some molds are toxic. Insects and critters of all kinds love the damp environment as well. The Clean Space encapsulation system completely isolates your home from the earth. This dramatically reduces the humidity level in the air which, when combined with sealing outside air and dehumidification, will eliminate mold growth and rot from your crawl space and make the whole house a healthier environment.

This O'Fallon,IL home has many issues with thier leaks.  The rooms are too hot/cold, dusty, and allergens are getting into the home.  The knee wall was insulated and air sealed with SilverGlow foam board.  This blocks off the air penetrations coming in between the walls.  Baffles were put in to keep ventilation throughout the attic.  Then fiberglass insulation was blown into the attic to have the house at the proper insulation level.

A knee wall space is created when a finished room is built within a sloped roof. Often, these walls are “insulated” using fiberglass batting. Since fiberglass does not stop air flow, the insulation does next to nothing to air seal and insulate----causing rooms sharing walls with knee walls to be very uncomfortable. Dr. Energy Saver St. Louis air sealed and insulated this O'Fallon, IL homeowner’s knee wall with SilverGlow insulation. Now, inside air can’t get out of the house through the knee wall spaces and outside air can’t get in. This bedroom is comfortable again!

Nottinghill Drive in O Fallon
I have house built in 2008 with central heat and air located in a finished basement. I'm looking to have the whole house duct work cleaned and sealed. Looking to gain efficiency by reducing loss in the duct work. Understand there is a sealant that will adhere to the walls of the duct and seal the gaps in the connections. Looking for a contractor that can do this work, can you do this work?

We have damage to our roof. USAA has called if an ice dam. The attic insulation was wet and ceiling drywall was damaged. USAA sent a restoration company but they said the insulation in the attic was dry. We would like another assessment because we are concerned at the quality of the insulation now.

Would like to have someone loook at our insulation to make sure we have the correct amount. Also, the bedrooms opposite of the master bedroom are always warmer than the master.
