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.

This basement was having water problems. We added a Trenchdrain, DryTrak, and sump pump to remove water from the basement.

As you see from the before picture we opened up the floor around the walls to install TrenchDrain and Waterguard and a TripleSafe Sump pump to remove water from the basement. On the outside of the house we put in Iceguard to prevent water from backing up as a result of frozen pipes.

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
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.

We have a very old home. Our basement often gets water in it when it rains heavily. We currently have sump pumps, but in heavy storms, they don't keep up. We are interested in considering whether we can waterproof it to prevent this in the future.

Sunset Road in Darien
We moved into a new home in June and have had several instances of water in the basement. It appears to be seepage from the wall or adjacent crawl space. Our initial hope was to finish the space for kids play area but we have had to put that on hold to fix any water issues. We would also be interest in a assessment of the condition of the crawl space/foundation generally.
