This Middlefield, CT basement used to be cold and unwelcoming, with cement walls and floor. Our team installed our ThermalDry flooring and ZenWall panels. The ThermalDry flooring makes your floor's surface 8-10°F warmer than the concrete surface below, and ZenWall provides some insulation and a beautiful, clean look. Together, they transform this basement into a comfortable space that's a great asset to the home!

Whenever it rained, water would flow into the basement from under the door. We installed a French Drain in this home, which is grated on the top to catch any water that would enter the house. Once the cement around it dries, it will keep water from flowing into the basement for years!
