This company waterproofed our house when it was owned by a previous family. The cinderblock foundation showed signs of caulking concealing horizontal cracks, and the French drain was not properly installed. We have had plenty of other companies and a structural engineer look at our basement, and all believe that a waterproofing company possibly painted and caulked the cracks. The walls were not supposed to be painted with the material used. Paperwork was left behind tying this company to the work, since we still had one more year of the warranty when we moved in a couple of years ago. I tried to contact our local contractor multiple times to discuss the project, with no response. Bad work done by bad people. Would not recommend.

The room had a lot of problems. We are cut into a hill and water seeped in causing mildew and mold so in this instance, I had already had the mold remediated and they came in and waterproofed it Start and built a room up from the studs with flooring, drywall and cabinets, an air purification system, which is really wonderful plus a sump pump… Quite a project, but totally necessary Kevon and Chris of Connecticut Basement Systems did a great job with this room, they were easy to work with, cheerful and put in many long days of focused effort which involved really extensive waterproofing renovation and a complete overhaul and refurbishing in general… Now the room has a very hip black beam ceiling and LED lighting on a dimmer as well as very nice flooring. Chris and Kevon also did the paint and they were very responsive in fixing minor details on a punchlist which really enhanced the look and the finish of the project. Julie Marra was a very good manager who shepherded the project over months time. This was a complicated project which has its genesis late in 2025 and was just completed recently because of different scheduling aspects and permit approval… the final result was wonderful. I would not hesitate recommend C.B.S. for this type of project.

Awesome service and communication

I continue to be impressed by this small business. We contacted them over a decade ago for a disaster and after getting through the crisis, we installed a dehumidifier that I joke is the most valuable thing in our house. Something went awry and I called for service and it was straightforward and affordable. And while it isn’t a requirement for the work, Devon was a delightful service provider explaining the issue, running diagnostics, and recommending a plan to keep it running well. Incredibly pleased once again by this company.

I called to address a concern about some small leaks of water in my basement that was covered under warranty by the past owners. Not only did the company honor the free service check, but they hunted down the problem which arguably has nothing to do with the basement. Despite that, Nizier C was thorough, tenacious, and intelligent about locating the issue and addressing ways to fix it easily and inexpensively. He listened to my concerns, looked at pictures, and used his expertise to share with me. His main goal was fixing the problem regardless of whether its source was the ground or not.

Always helpful and professional, they take good care of our system.

Chuck Stofko gave us a very honest appraisal of the cracks in the cellar wall and said that they didn't need any repair. CT Basement set up an appointment in two days. Great service.

We had a wonderful experience with Vin. He walked us through the whole process and made us very confident our basement water issues would no longer be a concern.
