WaterGuard and CleanSpace in Greenwich, CT

Before After
WaterGuard and CleanSpace in Greenwich, CT WaterGuard and CleanSpace in Greenwich, CT

Before, this Greenwich basement was damp and had a concerning moisture issue. This left the area to be unwelcoming and a nuisance for the homeowner. Wanting a solution, he decided to call Connecticut Basement Systems! 

The solution for this basement was to install a WaterGuard system. This product is a below the floor drainage system where water is collected and channeled from the WaterGuard to a sump pump where it will be discharged away from the home. The system is concealed with cement which you can see around the perimeter of the wall in the after photo. To control the moisture problem, CleanSpace Liner was installed on the walls. This moisture barrier is a durable, bright white liner that prevents water vapor and humidity from passing through. The dynamic of these waterproofing products will provide a dry and healthier basement. The homeowner was impressed with the transformation of his basements and how well the waterproofing products work. Now, this Greenwich homeowner can enjoy a dry and welcoming basement!

This resident from Riverside, CT mainly used their basement as a storage area, however, they wanted to finish their basement to give a simple, more comfortable look. Foreman, Sheldon Lennon and his team began by installing our EverLast Walls and Ceiling Linen to give this basement a rich and brighter look. In addition, our team installed ThermalDry Elite Plank Flooring to achieve a polished finish while ensuring that the floors remain free from warping. Now these homeowners are excited to finally utilize their newly finished basement!
