This basement was taking on water. To fix this issue we installed our Waterguard system around the perimeter of the basement. The WaterGuard system allows water a channel to the sump pump without flooding the basement.

This Shelton home had a tremendous amount of moisture underneath the home. This caused the bottom beams holding up the house to sag. This was very dangerous to the homeowners and the home. These unhappy homeowners called CT Basement Systems to fix this issue. We came out and the homeowner now has our CleanSpace Crawl Space Vapor Barrier System. The white crawl space liner is installed on the walls and floor of the crawl space to prevent mold and moisture from happening and damaging the home. This great system comes with a 25 year warranty, for rips and tears. We make it easy to repair your wet crawl space, by providing a free inspection and estimate.

This Shelton, CT homeowner was tired of looking at the cold, damp concrete floors in his basement. They had comfy, plush couches, but no floor under them to make the basement look like home. The home being close to a body of water certainly didn't help matters! They decided to give us a call at Connecticut Basement Systems, and we were happy to come out, and offer them a solution to their problems!

Our System Design Specialist came out and took a good look at this family's basement. He quickly knew just what they needed. They sent out Tony Dilonardo to the house, where his team went ahead and installed our ThermalDry Flooring Tiles in Canyon Beige. These flooring tiles completely transform your basement, and come in all colors and designs in the same 12 inch, square-shaped, snap together design. These tiles are strong, durable, and immune to moisture damage. For a home closer to the water like this one, they're a perfect option. The underside of each ThermalDry tile features construction that creates a drainage plane, as well as a thermal break to shield your feet from the cold concrete floor.

This family now feels comfortable bringing guests into their basement, and have a cozy evening at home! Give us a call TODAY for your FREE ESTIMATE!

There is a section in my basement (front right corner) about 10 feet long and 2 feet wide (from the front wall of the foundation) where the floor is cracked in almost a complete rectangle. It seems to have pulled from the front foundation wall a little bit, and seems to have sunk or is on a slant.
