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!

We had water with the last two big storms due to a malfunctioning sump pump. The musty/moldy smell lingers. We did the best we could to clean and remove anything that got wet. Not sure if we missed anything.

Hello, Although we have a giant sump pump with a 4" pipe that drains out to our seawall, plus 5 other drains to the sea wall, and have trenched outside the basement and installed pitched perforated piping to one of the drains, we still experience groundwater flooding periodically. Hoping you can take a look and make a suggestion.

Basement has flooded multiple times this summer / fall. Need waterproofing and sump pump installation.
Project Location: Darien, CT
Our basement has finished, unfinished and crawlspace areas. We would occasionally get water in the crawl space but installed a surface pump and that would be enough to handle any water that came in. Recently we have had so much water coming in it overwhelms the crawl space pump and goes into the other areas. Water has also started coming in from other area in the unfinished side.
