Here we used a Trench Drain system to direct water out of the garage. BrightWall was also added to keep the walls from molding and brighten up the space. We also used an IceGuard system to prevent water from backing up during cold connecticut winters.

Job Stories From Darien, CT
ThermalDry Flooring in Darien, CT

This homeowner wanted a new floor that would make his basement more comfortable for all to enjoy. Originally, he had concrete floors that were cold and unpleasant. Wanting a solution, he decided to trust the experts at Connecticut Basement Systems.

On the day of the free, no-obligation appointment, Sales Representative Anthony Martingano arrived at the home to assess the situation. The best solution for his floor needs was to install ThermalDry flooring, a superior option. ThermalDry looks great in any basement and is 8-10 degrees warmer than traditional concrete. The homeowner agreed that this was the best solution and wanted to move forward with the project.

Foreman Kevon Barnett installed the ThermalDry flooring professionally and efficiently. Once the project was completed, the homeowner was impressed with the transformation of the basement. Not only did the floors look beautiful, but they were practical and comfortable. This is exactly what the homeowner wanted and was happy with the results!

Looking to install a french drain and sump pump
Vicinity of Gardiner Street in Darien
I have a sump pump and a battery backup sump pump (to be installed). They both failed at the same time! The water is cleaned up but the walls are weeping (old fieldstone foundation). The walls were drylok-ed at some time in the past, but the drylok is peeling off now. Also the sump outlet is buried underground and has cracked, so the water does not make it to the outside drain. I need a better solution. Also, I have a property in Cos Cob, over the years the concrete front sidewalk has sunk and heaved in places. would like a quote to lift/level the sidewalk.
