Here we have a before and after of a basement located in Wilton, CT. Before it was a gray, bland, lifeless basement where the owners could not take advantage of their own space. Now, after installing our ThermalDry parquet tile to the floor, it brightens and opens up the room making it more inviting for whatever potential the owners have in mind. These homeowners took advantage of the space and created an in home gym!

TripleSafe Sump Pump in Wilton, CT

This old, open sump pump wasn't doing its job. It kept clogging, and water would evaporate out of it and cause the basement to be humid. We replaced it with our TripleSafe sump pump. Its airtight cover reduces sump pump noise and keeps dirt and debris from falling in. Additionally, TripleSafe's oversize plastic sump liner contains 3 sump pumps that can work together or separately depending on pumping demands. With the TripleSafesystem, you don't have to worry about high pumping demands that can overwhelm or burn out single-pump systems. And if there's a power outage, your TripleSafe system will keep operating, thanks to a battery-powered backup pump.

Job Stories From Wilton, CT
WaterGuard System in Wilton, CT

This Wilton home had a water problem in the basement that concerned the homeowner. She wanted to have a dry basement all year around. After doing her research, she decided to trust the experts at Connecticut Basement Systems to help find her a solution. 

On the day of the appointment, Sales Representative Mick Foster arrived at the home to inspect the basement. He noticed that the bottom of the basement walls were damaged caused by this water problem Mick explained that we had a product to address each concern of her wet basement. Wall restoration will replace the water damaged walls and a WaterGuard system will prevent water from entering the basement. While Mick was there, he also noticed that there was a lot of humidity in the area of the basement. This could be solved with a SaniDry Dehumidifier, which will control the humidity in a basement to be under 55% which is the ideal percentage to have cleaner, healthier air. This sounded like the perfect solution to ensure that this basement will stay dry and healthy all year long. The homeowner decided to go through with the project. 

On the day of production, Foreman Krzys Wilk and his team installed every product professionally and efficiently. The project took a total of two days and the homeowner was impressed with the installation. Now, she can enjoy a healthy and dry basement every day!

My dad's house has a crawl space under the house that has a lot of moisture. I wanted to pursue a solution to keep it dry -- or as dry as possible -- under there.

Moisture in basement is making engineered hardwood flooring begin to buckle. The basement/lower level is finished living space (bedrooms). House built on slope so one side is below grade and one side opens for walk-out to grade.
