When water seeped into this Madison, CT basement, it had no place to go. To drain it away and get it out of the house, we installed the SuperSump sump pump and WaterGuard perimeter drain. WaterGuard, which is underneath the freshly poured cement, will catch water coming from the outside before it enters the basement. It then flows to the SuperSump pump. With its Zoeller ⅓ horsepower cast-iron sump pump, it will keep the basement dry for years to come!

The homeowners of this Madison, CT home had a continuing moisture issue in their basement that simply would not go away. They contacted the experts at Connecticut Basement Systems to fix this once and for all. We tackled the entry way first because it was clear that humid air was seeping into the basement. The homeowners were covering up the entry way gaps with towels but that was clearly not working! We installed a fiberglass door and then air sealed around the door to prevent any humidity from getting into the basement. 

The homeowners not have a drier basement and a new door that will last a long time!

Job Stories From Madison, CT
FlexiSpan Crack Repair in Madison, CT

This Madison home had a crack in their basement wall that was seeping out water and air. This was concerning for the homeowner and he wanted to find a solution to ensure that he would have a dry basement. He did his research and decided to contact the experts at Connecticut Basement Systems to help find him a solution.  

The solution for this home was to install FlexiSpan which is our wall crack repair system. This process will permanently stop water leakage through basement wall crack. The installation of this solution begins with the application of a flexible sealant along the full length of the crack. Then, a strip of flexible and porous foam is installed over the crack. Finally, an impermeable membrane is attached to the wall on both sides of the foam strips. And unlike sealant or mortar-based crack repair, the FlexiSpan system is not adversely affected by hydrostatic pressure or slight movement in the basement wall. This is exactly what the homeowner needed and was happy that he had a dry basement again! 

Foundation Repair in Madison, CT

This Madison, CT homeowner had noticed cracks in his walls, expansion of concrete, and the chimney separating from his house. With a concern of his home's safety, he gave Connecticut Basement Systems a call to help with Foundation Repair.

Our System Design Specialist, Matt Kraus, arrived at the Madison home to evaluate the foundation problem. He concluded that Push Piers and PolyLEVEL would need to be implemented to correctly repair the foundation problem. With a plan set, Sergio Alves and his production team got to work. They installed Push Piers to connect the house to stable, load-bearing bedrock. With the piers set, a steel bracket and hydraulic jack are connected to each pier where the foundation is hydraulically lifted back to its original position. PolyLEVEL was used to lift settled slabs around the home.

Once the job was finished, this Madison, CT homeowner enjoyed his home without the worry of foundation problems and our crew was happy to help!
