Job Stories From Newington, CT
ThermalDry Flooring Installation in Newington, CT

This Newington, CT homeowner was looking for an attractive, but safe flooring method for their home. While they wanted it to look nice, they also wanted to reduce the risk of water damaging the floor. They gave us a call at Connecticut Basement Systems, and we knew our ThermalDry Flooring was just the solution they needed. This flooring was made for basement environments, and it's 100% waterproof. Since each tile sits on raised pegs, it creates a thermal break from the cold concrete underneath. The floor will be 8-10 degrees warmer because of it! Best of all? You know your flooring is waterproofed, while feeling comfortable and confident in the finish the flooring has!

I have a French Drain System in my basement. I never had a problem with it until the house next to me caught fire 2 years ago. It's hard to explain in writing. You would have to see it. I'm getting mud and water in a section of the basement. And the Well Liner doesn't look so good either. Water is also coming up from under the liner. There's also some mud in the pipe going into the well.

Looking to get a quote for finishing my basement

Hello, I am searching around for information on mold remediation for a residential property. We have a concerning amount of mold inside of a ceiling in a sectioned off hallway. I'm not quite sure how long it's been exactly but I know it's been a problem for some time now. I know we won't really know how much the process will cost, but how much would we be looking at for about 5 sqft or so of a medium amount of mold removal? I can be best reached via email. Thank you
