Basement Finishing & Remodeling in New Rochelle, NY

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly finished basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include :
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors
Unlike the average New Rochelle contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive finished basement that lasts a lifetime.

Job Stories From New Rochelle, NY
WaterGuard , TripleSafe and ThermalDry Flooring in New Rochelle, NY

This New Rochelle home had a wet basement that was due to an insufficient sump pump. The homeowners wanted a sense of security when it rained that they would not have a wet basement. Wanting a dry basement, they sought out the best company to provide a solution to their problem. After hearing some great testimonials from previous customers, they decided to trust the experts at Connecticut Basement Systems and scheduled a free, no-obligation estimate.

On the day of the appointment, Salesman Anthony Martingano arrived at the home to assess the situation and provide the free estimate. Upon his investigating, he concluded that the best solution would be to install our waterproofing system, the WaterGuard paired with a TripleSafe sump pump. Anthony explained that the WaterGuard system would be installed below the floor along the perimeter of the basement. It will internally collect water seepage before it enters the basement and channel it to the TripleSafe sump pump. This sump pump can handle up to 2,200 gallons of water which will add security to any amount of water that would want to come through. The homeowners also expressed that they were thinking of adding new flooring. Anthony suggested our ThermalDry flooring which comes in a variety of colors and will not allow any seepage to come through the floors. Plus, it is 8 degrees warmer compared to traditional concrete. After much consideration, the homeowners wanted to move forward with the project as they knew that this would be the best solution for their home.

On the day of installation, Foreman Krzys Wilk and his team installed all the products professionally and efficiently. They first had to waterproof the home by installing the WaterGuard system. The perimeter of the basement was excavated, and the system was placed. It is connected to the TripleSafe sump pump (which is also installed) and is backfilled with gravel then sealed with cement. Once that was completed, they were able to install the flooring. The basement was transformed into a nice, dry area where the homeowners were comfortable to be in!

WaterGuard and ThermalDry Flooring in New Rochelle, NY

This New Rochelle homeowner had a water problem in her basement. She wanted to keep her basement dry at all times. Wanting a solution, she decided to reach out to the experts at Connecticut Basement Systems to help find her a solution.

On the day of the free, no-obligation appointment, Sales Representative Anthony Martingano arrived at the home to assess the basement. After inspection, he concluded that a WaterGuard System would be the best solution. This system will collect water internally and channel it to the TripleSafe sump pump. In order to keep the basement’s air quality healthier and drier, a SaniDry Sedona was suggested. This dehumidifier will keep humidity below 55% which will also deter any mold from growing. The homeowner had expressed that she was interested in new flooring for the basement. Anthony had recommended ThermalDry Elite flooring. This superior flooring option is durable, waterproof and is 8 to 10 degrees warmer than concrete floors. The homeowner was excited for all the products that would make her basement dry and comfortable. 

Foreman Krzys Wilk and his crew installed all the products professionally and efficiently. Upon completion, the homeowner was impressed with the products and how well they all worked together. Now, this New Rochelle homeowner can enjoy a dry basement all year long.
