This basement was getting water leeking in. To fix this problem with installed Waterguard, Trenchguard and a SuperSump system to remove the water. On the outside of the house an Iceguard was installed to prevent water back up during the winter months.

This Old Greenwich basement had reoccurring water issues. Clearly, part of that problem was caused by an insufficient sump pump. The homeowner wanted a solution to keep his basement dry all year around. After doing some research, he decided that Connecticut Basement Systems was the best company to help with his basement needs.  

Krzystof and his production crew installed a SuperSump pump and a CleanSpace Vapor Barrier as seen in the after photo. What a transformation from the before photo! The SuperSump has a powerful Zoeller 1/3 horsepower sump pump which has the ability to pump 2,220 gallons of water away from the basement! The CleanSpace Vapor Barrier prevents water seepage entering the basement through the walls.  

With the combination of these two products, this Old Greenwich homeowner can enjoy a dry basement all year around!

Ferris Dr in Old Greenwich
A recent inspection report revealed elevated levels of certain types of mold in the air (highest in basement, and next in the 2nd level). We would like a quote on treatment/mitigation of the mold issue. The basement floor does not get wet - the prior owners had a system installed we believe by your company some years ago.

We have a water seepage problem in the basement. We installed a sump pump last year, but the water seeping in from the walls and door does not reach the pump area. We need to do a trough along the walls and paint the walls with sealant.

Havemeyer Lane in Old Greenwich
The floor in one room has sank on the borders by about 2 inches. The floor is right above the crawl space. It seems it happened some time ago. A bathroom adjacent to that room also went down a bit (less than an inch). The condition seems to require an immediate attention. Thanks.
