This Sandy Hook home had water seeping in through the cements walls underneath the insulation and made its way into the drywall damaging it. The homeowners called the experts at CT Basement Systems and Brad diagnosed the issue and fixed it. To guide the water out of the home we installed our WaterGuard below floor drain. The WaterGuard is installed in a bed of gravel on top of the foundation footing which keeps it out of the "mud zone". The water is then collected and pumped out of the home by our premier SuperSump which is capable of pumping 2,200 gallons of water per hour. Because the previous insulation was damaged we installed our ThermalDry Basement Radiant Wall Barrier. The ThermalDry® Wall system protects the finished basement from moisture and water that passes through concrete foundation walls. This product serves as both a vapor barrier and also as a way to redirect water leaking through the basement walls into the drainage system below.

We currently have an 800sqft unfinished basement that we would like to have finished.

Project Location: Sandy Hook, CT
We live in a house that was built in 1726 and has a stacked stone foundation. It often smells musty, even with a dehumidifier. We would like to look into sealing the walls and perhaps adding a drain to the floor so that we can drain our dehumidifier water directly out of the basement. We would appreciate a consultation and estimate.
