When we first visited this home, water was leaking in dramatically. To fix this problem we 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!

Job Stories From Old Greenwich, CT
Basement Waterproofing - Old Greenwich, CT

A homeowner in Old Greenwich, CT expressed concerns regarding her basement. Frustrated with pools of water scattered across the floor despite her pre-existing sump pump, she decided to make a change. Reaching out to the experts at Connecticut Basement Systems, the homeowner made contact with Sales Representative Mick Foster.

During Foster's phone call with the homeowner, he offered a free in-home inspection to help determine the best solution to address her concerns. Shortly after, Foster arrived at the home, taking measurements and putting together a map of the space. Ultimately, Foster suggested installing a TripleSafe sump pump, CleanSpace vapor barrier, and WaterGuard perimeter drain. By implementing these systems, the homeowner's basement would be much more protected against unwanted moisture.

With Foster's proposal approved by the homeowner, Foreman Joe Schech and his team arrived on-site to begin the installation process. Removing the old sump pump, a brand new TripleSafe featuring three levels of protection against basement moisture was installed. 

Following the install, the homeowner was thrilled with the results! Now, moisture is funneled into the TripleSafe pump where it is expelled at a safe distance from the house.

We recently bought and moved in to the house (4 months ago) we have three young children and want to consider optimizing the extra space in the basement but only if it would be safe to do so, ie. Needs to be waterproofed, make sure there is no asbestos, mold and it would be worth the investment to convert it to a finished basement.
