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.

As you see from the before picture we opened up the floor around the walls to install TrenchDrain, 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!

Dampness in middle of basement finished floor, it is my kids play room - we want to put down new floor but need solution. Also there is water around the sump pump outside the house which doesn't seem right.
Project Location: Darien, CT
Our basement flooded. The sump pump worked the whole storm, but it wasn't powerful enough to handle the volume of water received. Also, it seems the water around us started seeping through the walls of the finished portion of our basement. We are looking for waterproofing solutions and possibly a more powerful sump pump.
Project Location: Darien, CT
Water in basement found during last storm / flash flooding. Happened another time a few years ago.
Project Location: Darien, CT
Looking to avoid future water damages in the future, possibly a pump installed.
Project Location: Darien, CT
After the storm, we have seen some water coming in to our basement. We are new to the house so aren't sure if there are structural issues or if this is a one time thing. We've dried the leaks but they do continue to build up.

We live by a stream . We have a seepage drain in the corner of the basement and like 30 years before the water rose above the pipe that leads away from our property and we had 4 inches of water in the basement . Enough is enough. I think we need a sump pump and or full evaluation of our basement to make it mostly water resistant . We need your help!

We just moved into the house. After overnight rain we found water in our basement. Some of the seep I suspect to be from our gutters, but I'm also concerned that there may be leakage through the foundation. House built in 1930.

I need to schedule an annual maintenance check up on my sump pump that you installed a while ago.
Project Location: Darien, CT
Part of our house is on crawlspace - and there is an area that we I suspect we need a footer added (the floor sags above it). I wanted to get a professional opinion on it. The homeowners before us had placed a car jack (yes, you read that correctly) to help prevent the floor from sagging.
Project Location: Darien, CT
