Before and After Pictures from O Fallon
Clean Space in O'Fallon,IL

Clean Space in O'Fallon,IL

Clean Space in O'Fallon,IL Clean Space in O'Fallon,IL

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!

Job Stories From O Fallon, IL
Crawlspace Repair in O'Fallon, IL

Paul of O'Fallon, IL really didn't like the way his crawlspace looked and wanted to feel less intimidated any time he needed to go into his crawlspace so he contacted Woods Basement Systems, Inc. for a free quote. Woods sent one of their System Design Specialists, Aaron, to inspect Paul's crawlspace and give him an estimate. Aaron felt strongly that Paul needed a CleanSpace Liner to give his crawlspace a more inviting look. He also believed Paul needed a few waterproofing materials to keep his crawlspace dry. 

Feeling that Aaron's suggestions were exactly what he needed, Paul scheduled a day for one of the foremen at Woods, Joshua, to install the liner and the other materials he needed for his crawlspace. Joshua and his team spent an entire day installing everything Paul's crawlspace needed, and after the project was completed, Paul was very satisfied and rated the work as a ten.

O'Fallon, IL Radon Mitigation Installed

William bought a radon test kit and found out he had high levels of radon in his basement. Concerned, he contacted Woods Basement Systems, Inc., and they sent one of their system design specialists, Ken, to give William a free quote.

Ken did a secondary test to confirm the presence of radon and determined William needed a radon mitigation system installed. After William agreed with Ken's diagnosis, he set up an appointment with Woods Basement Systems, Inc. and scheduled for Chris, one of the company's foremen, to install the system. 

A few weeks later, Chris and his team installed the mitigation system and recommended William schedule another appointment within 30 days to ensure the system is keeping the radon levels in check. Satisfied with Chris's work, William felt better that the radon levels in his basement weren't a problem anymore.

O'Fallon, IL Wall Anchor Foundation Repair

Ken owns an older home in downtown O'Fallon, IL and noticed two of his basement walls bowing and cracking. Concerned, he called Woods Basement Systems of Collinsville, IL, and the company sent their Sales Rep, Daniel, to inspect his property and determine diagnosis. After assessing Ken's basement, Dan concluded that Ken needed 13 units of Geo-Lock Wall Anchors to stabilize his basement walls. 

Once diagnosis was distinguished and products were sold, Woods Basement Systems appointed one of their foremen, Todd, to supervise the production of the project. Todd and his crew drilled several deep holes throughout Ken's yard and installed the Geo-Lock Anchor System within the ground as well as against the walls of the basement. After all anchors were locked and installed, Todd and his crew filled the holes they created and repaired Ken's yard with new patches of sod. The entire process took a day and a half to complete, and after Todd and his team finished everything and left, Ken was greatly satisfied with the results.

Woods Keeps Basement Dry Lebanon, IL

A resident of Lebanon, IL had been living in her century-old house for 13 years.  She had been having the issue of water in her basement ever since she moved in.  It was always on her mind to get the problem fixed, but she never got around to doing it.  She finally called Woods Basement Systems and was relieved to discover that they could solve the issue once and for all.

Woods installed the total waterproofing package for the resident—IceGuard, TrenchDrain, WaterGuard, and a TripleSafe sump pump.  Now, when it rains heavily, the TripleSafe is able to keep up with the amount of water and pump it away from the home—resulting in a dry basement and a happy customer.

The resident was thrilled with the ending result and enjoyed not having to worry about a wet basement anymore.
