This family in North Stonington, CT was tired of having a dirty basement that often leaked and flooded with water. They wanted a space that was comfortable and inviting, so they gave us at Connecituct Basement Systems a call, and we were happy to come out!

Taz Petersen, our System Design Specialist, quickly came up with a solution that would best suit this family's basement. Kryz Wilk and his team came out, and got ready to take on the task at hand. They first installed WaterGuard around the perimeter of the basement, which paired wonderfully with our SuperSump. These two products work together to create a first class drainage system for any basements. We also encapsulated the entire space with our bright and durable Cleanspace Wall System. This not only makes your space look brighter and cleaner, it also works to keep vapor and moisture out of the basement! 

This family felt much better about using their basement for all of their storage needs! Give us a call TODAY for your no cost estimate!

I have a garage that has a very high humidity reading at all times. I would like to discuss options as well as some other thoughts/concerns with the rest of my basement. I am hoping to have someone (with heavy experience (please don't send me someone new ;-) ) to discuss a number of things.
