ThermalDry in Stratford, CT ThermalDry in Stratford, CT

This Stratford basement originally had unappealing, cold floors. Of all of the surfaces in your home, floors are the ones you come in most contact with. Not only were these floors an eye-sore, but this made the basement cold and unwelcoming. This homeowner wanted a flooring system in his basement that was waterproof, appealing and warm. After some research, he decided to give Connecticut Basement Systems a call. 

Our Sales Representative, Brad Glazer proposed that the homeowner should install ThermalDry Carpet. This product is stain resistant, does not support mold or mildew, and will keep a floor dry and warm all year long. With approval from the homeowner, Sid Avis and his production team installed the ThermalDry Carpet efficiently and professionally. They even mix and matched two different carpet styles to create this checkered look for added appeal. 

Now the homeowner enjoys a lovely and warm basement floor!

Job Stories From Stratford, CT
SaniDry Sedona in Stratford, CT

This Stratford crawl space was filled with moisture and debris. She knew the problems in her crawl space were reflecting through her home. Wanting a solution for her crawl space, she decided to give Connecticut Basement Systems a call! 

On the day of the appointment, Josh Kroop arrived at the home to evaluate the crawl space. He concluded that in order to keep the crawl space clean and dry, he recommended that she install a CleanSpace Liner and Sanidry Sedona. The CleanSpace will act as a vapor barrier which will help keep any air or moisture from entering the crawl space. The CleanSpace is also made with a white material which gives the crawlspace a fresh, clean look. The Sanidry Sedona is a dehumidifier that will keep the area dry which will prevent any mold growth. The homeowner wanted all of these products and quickly scheduled a production date.

On the day of production, Garfield Sanderson and his team installed the products efficiently and professionally. First, they removed any debris from the crawl space to have a fresh start. Then, they added drainage matting to the floor to ensure any water that comes in contact to the floor has a proper escape. Next, the CleanSpace Liner was installed and the Sanidry Sedona followed. The homeowner was happy with how all the products worked together to keep her crawl space clean and dry all year around!

I have two small crawl spaces in the basement of my home (purchased in August) that I was looking on getting a quote on addressing (I believe what I am looking for is called encapsulation). I am experiencing various pest issues including mice and termites, and I was told addressing the crawl spaces may help. I was also looking for any recommendations on the general basement area as it relates to moisture and whatnot. Thank you!
