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!

I need to schedule an annual maintenance check up on my sump pump that you installed a while ago.
Vicinity of Phillips Lane in Darien
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.

Hi! We are in the process of doing inspections for a house we are trying to purchase. During the general inspection, some issues came up with mold, sump-pump system, potential water penetration problems in the basement and wanted to also evaluate the foundation. I was hoping to get someone over to the house today/tomorrow if possible. Please let me know if we can have someone come out to evaluate and give a repair estimate! Thanks, Kristin
