Before After
TripleSafe Sump Pump and BrightWall in Prospect, CT TripleSafe Sump Pump and BrightWall in Prospect, CT

Before, this Prospect home had a wet basement due to an insufficient sump pump. The walls of the basement were also dreary and it made it even more unpleasant to walk downstairs in addition to the water. The homeowners knew they wanted a solution so they contacted the experts at Connecticut Basement Systems. 

The solution for this basement was to install our TripleSafe sump pump. This is our best sump pump option because it has 3 pumps to handle any amount of water that would otherwise enter the basement. This is paired with our full perimeter WaterGuard system that will collect and channel water to the Triple Safe for proper discharge. This system will waterproof the basement. To solve the basement wall problem, BrightWall panels were installed. This paneling is durable and is also waterproof and mold resistant. With these panels installed, the entire basement is more welcoming, which is exactly what the homeowners wanted. They were very pleased with all the products and how well they worked together for a waterproof basement.
