Job Stories From Ledyard, CT
Waterproofing Job in Ledyard, CT

This family in Ledyard, CT was looking for a full proof solution when it came to waterproofing their basement, and when they called Connecticut Basements for help, we were happy to do the job! 

After our System Design Specialist came in, and figured out what was best for the family's space, we called on our expert foreman to take on the job at hand. We first went ahead and installed our TripleSafe Sump Pump. This three pump system works together, and separately, to ensure that any water getting into the space will have no effect on their home.  If there is too much water for the first pump to handle then the second pump works at the same time from another discharge line. We also installed a WaterGuard around the perimeter of the basement.
