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.

I never had water in my basement until the last month. Believe it may be related to footing drainage. Have had to had water vacuumed twice so far after rain. Please call me asap. Need to get this resolved and very concerned about costs. I work f.t. please leave message and I will get back to you. I was impressed with the very positive comments on the internet from other customers in Newtown,Ct where I live in the Sandy Hook section.
