Comments: Great job and quality work for installation of the radon system. The guys adjusted the location of the fan and the exhaust pipe for me with no issues. Got the work done quickly and kept the area neat and clean. Great customer service.

Comments: Knowledgeable, professional, and and quite good at their jobs. Everyone was polite, mindful of what needs to happen with social distancing, but also more then willing to explain everything they were doing. I would highly recommend CT Basement!

Comments: They were wonderful to deal with, quick to return phone calls. The crew was courteous, and efficient. The Radon system worked and we went from a rating of 7 to a rating of 2. So I am very happy with the product.

Comments: I was so impressed with the level of communication between the company and its customer. I had to contact them many times due to problems with my water and the requests of my buyers inspector. My calls were returned promptly by all involved. They have a professional and qualified staff

Comments: Connecticut Basement installed our Radon System 5 years ago and did a fantastic job so we hired them to install our new water softner. During the install it was discovered and verified by me that the well pump was defective (19 years old) and they managed to do all the work plus the well pump in the same day. Without the well pump we could have gone days without water. They were here at our house for 9 hours. Super service!!
