This Danielson, CT home's basement was suffering from water damage all along the walls. They were made from stone and cement. Both of these materials aren't great when it comes to keeping water out of your basement. When the groundwater fills up it will eventually seep through the cement and stone. in order to address this problem we installed our CleanSpace Vapor Barrier and TripleSafe Sump Pump. The vapor barrier is water and mold-resistant so it stops rot, mold, foul odors and insects from entering into your space. Our sump pump is an award winning, industry leading sump pump. It offers more reliability, power, and performance unlike any other sump pump on the market today. (To learn more about our sump pumps click here!) This basement is now dry and usable for endless possibilities! This family couldn't be happier with their newly transformed space.
