Before After
ThermalDry Flooring in Windham, CT ThermalDry Flooring in Windham, CT

Before, this Windham home had cold, concrete floors that were uncomfortable. It was difficult for the homeowner to spend any time in his own basement. He wanted flooring that would be both warm and attractive in the area. He decided to trust the experts at Connecticut Basement Systems to get the best floor options for his basement.

The homeowner decided to have ThermalDry floor carpet installed. This product includes a thermal break from the cold slab that makes the floor surface up to 10 degrees warmer. There is a grid design which prevents water vapor from getting trapped under the floor. This will prevent odors and mold. This is exactly what the homeowner wanted and was pleased with the transformation, just look at the before and after!

Job Stories From Windham, CT
Waterproofing and Window Installation in Windham, CT

Lee H. in Windham, CT had water damage after a storm in her Windham home, and needed a solution. They found Connecticut Basement Systems, gave us a call, and we were happy to come out and get the job done!

The first thing we did was we installed a WaterGuard drainage system around the perimeter of the basement. This underground drainage system is a non-clogging alternative to other drainage systems, and it's wall-flange design hides so you won't see it on your basement floors. We also installed our Everlast windows, which are vinyl framed, energy efficient, and best of all? Waterproofed! These dry basement products will not decay when exposed to the elements, and they maximize the beauty of the basement space. 

Lee left with a fresh, clean basement, and we were happy to help! Give us a call TODAY for your free estimate!

I have a 150+ year old home with a primitive basement. We poured a floor 35 years ago but occasionally get water that seeps through the stone walls. A little trenching around some of the perimeter and a sump pump would eliminate that problem. I think
