Looking into basement finishing.
Project Location: Andover, CT
Looking for direction regarding CMU wall; de-humidification; patching flooring (for radon mitigation); and looking for estimate to "lower" the floor approx. 18 inches?
Project Location: Andover, CT
We are having our basement finished currently. Walls, trim are completed, he's working on the ceiling. After Fridays storm, we have water in the basement. It appears to be coming in on one wall right where the tie rods are along the foundation, esp right around the pipes coming in to the well pump. This seems to be out of the realm of knowledge base for our contractor and you guys helped us with radon fix when we bought this house. We need some assistance ensuring basement is waterproofed before we will let contractor complete work.
