We had the problem of water accumulation in our window wells with water leaking through the casement windows. Experienced staff from Basement Waterproofing Solutions attended to this problem last week. They installed drain pipes through the concrete walls in the basement and pipes inside the basement in order to allow the water from the window wells to drain to the sump pump. They also installed a new sump drum and re-graveled the window wells. Further they installed a new line to transport the water pumped by the sump pump away from the structure to ensure proper drainage. They team worked very professionally and did a fine job. It so happens that we had heavy downpour the very next day, but we had no water accumulation problem any more. The system installed by Basement Waterproofing Solutions took care of the problem. I am very happy to recommend them!
