Basement Waterproofing in Ardsley on Hudson, NY

A customer in Ardsley on Hudson, NY was getting water in their basement and had existing water damage. They called us at Connecticut Basement Systems to find a solution to their problem. Once an appointment was set, it would be time for one of our Sales Consultants, Vin Orsini, to go to the home to estimate the issues and provide a solution.  Once a job was proposed it would then be time for one of our Foremen, Cisco Berrios, and his team to get started on the installation. They installed a WaterGuard perimeter drain system below ground to capture any water that might seep in. Then they installed a TripleSafe sump pump that will collect and pump out the water from the home at a safe distance. The crew also installed CleanSpace on the walls to act as a vapor barrier and protect it from any moisture. Now this basement is dry and the homeowner no longer has to worry about water issues!

Basement Waterproofing - Norwalk, CT

A homeowner in Norwalk, CT, was getting water seepage in their basement. They called us at Connecticut Basement Systems in search of a permanent solution. One of our Service Technicians went out to view an old system they had, and he proposed our full perimeter waterproofing solution.  Shortly after, one of our Foremen, Marcio, and his crew would install the job. They installed our dual drainage system, which consists of our DryTrak baseboard drain and a feed line, to ensure water seepage from the walls will be directed into our sump pump system. Then, they installed our CleanSpace vapor barrier on the wall to protect it from moisture and help direct water from the walls into the drain system below. Two of our TripleSafe sump pumps were installed., While only one is pictured, they will ensure the collected water will be safely pumped out of the home. Lastly, the crew installed our Sedona dehumidifier to eliminate excess moisture and prevent mold growth throughout the entire space. Now, this entire basement will stay dry all the time, ensuring the homeowner has peace of mind!
