A dry basement after repeated rain is what several customers describe hiring Connecticut Basement Waterproofing to achieve. The West Hartford business says it has 25 years in business and offers basement waterproofing, foundation repair, sump pumps and perimeter drainage, along with free estimates and 24/7 emergency service. In an October 2026 Google review, a homeowner said Bob and his team completed the work in two days and that the basement had remained dry for more than a year afterward. A May 2026 reviewer described Bob assessing the cause of basement leakage, then sending a crew including Bobby and Dante; the customer praised their efficiency and cleanup. In March 2026, another homeowner described calling on Monday about a leaking foundation crack, having Robert assess it Tuesday and a crew repair it Wednesday. The customer said the basement stayed dry after rain and snowmelt tested the repair. The work can include digging and installing drainage equipment. An April 2025 customer in North Stonington described Bob, Bobbie, Dante and Josh digging a trench around a basement chimney and installing a sump pump, then leaving the area clean. A February 2024 reviewer described a four-day dig and basement-system installation, protection of belongings from dust, and a return visit to fix a minor drip in a pipe installed for the sump pump. That customer said the crew took care of the issue and remained pleased with the job. There are also older warranty-service complaints. Two Google reviewers writing on August 25, 2022, described leaks after work they said carried a lifetime warranty. Both reported difficulty reaching the business and missed repair appointments; one specifically described Bob scheduling a visit and then not showing up. Those accounts sit alongside later customers describing dry basements, including February 2025 reviewers who said they remained dry months after the work. Google displays 4.7 stars from 32 ratings. BBB gives the business a C grade and reports one complaint. Its Connecticut home improvement contractor registration HIC.0603533 was expired when checked against the state registry on October 30, 2026.
Hands down the best money I've ever spent on a home improvement project.Bob and his team @CT Basement were in and out of my house in 2 days and the job they did was perfect. I haven't had a drop of water since they finished over a year ago.I was given a clear and concise estimate on the work they performed and they did everything they said they would and more. 5 stars
Prompt, courteous and complete service. Bob and his crew are the absolute best!!!
Can’t say enough positive things about Bob and his crew. Bob came out to assess the water leaking in my basement and described exactly what he was seeing, the root cause and what needed to be done to fix the issue. He sent out his amazing crew including Bobby and Dante. These guys were respectful, efficient and cleaned up after themselves. The entire crew is professional and knowledgeable and I highly recommend them. If I could give 10 stars I would!
I called CT Basement Waterproofing on Monday, set up an appointment to look at the leaking foundation Crack for Tuesday morning. Robert came out (on time) to check out the issue. He had his guys out Wednesday morning to do the repair. Very nice, professional from start to finish. Last night we had an inch of rain to add to the snow melt and test out the repair!! Today it's dry as can be!! Very pleased and would recommend them for sure 👍
Bob, Bobbie, Dante and Josh did a professional and amazing job today digging a trench around the chimney in the basement and installing a sump pump. They were artists of the trade and very clean leaving no mess behind. I am so glad I chose CT basement & waterproofing over any of the others. Such good and respectful people. I can’t say enough good things about this crew. It is also truly heartwarming to see a father and son team working together in the field. Thank you very much guys! I wish you could work on other non-basement things because I would hire you. No hesitation, 5-stars! Sincerely, A Happy Customer in North Stonington
