Job Stories From Mahopac, NY
Waterproofing Installation in Mahopac, NY

In this Mahopac, NY home, the basement was cold, uninviting, and suffering from mold and mildew damage. The family living in this home wanted a change fast, so they gave us at Connecticut Basement Systems a call to come and fix it!

Marcio Bahiense and his team came over, and they quickly got to work! First, a TrenchDrain and WaterGuard were installed. These two products are installed on the interior perimeter of the basement; the TrenchDrain on the entry way, and the WaterGuard around the perimeter of the basement. These products collect water from the stairs and walls, and lead directly to a TripleSafe sump pump. The TripleSafe sump pump is a not just a single pump, it is a sump pump system. It comes with one pump that can pump up to 2,600 gallons per hour, and the second, which allows it to pump up to 6,200 gallons. The third is a back-up battery, which is only turned on when the other two stop working. This allows the pumps to pump up to 11,000 gallons! With these three products, this basement will never have to worry about a flood EVER again.
