Our basement project is finally complete, and while the process took longer than we initially expected, we're very happy with the final outcome. The finished space turned out great, and the quality of the work really shows. While the project took a bit longer than expected, the final result was worth the wait. One thing that especially stood out to us was how kind everyone was to our dog, Ocean. Even while busy working, they always took a moment to say hello, tell him how cute he was, and make him feel comfortable. Those small gestures meant a lot to us and made the entire experience more enjoyable. Thank you to the entire team for your hard work, professionalism, and attention to detail. We’re grateful for our beautiful new space and are enjoying it every day. Special thanks to Ray, Alex, and Arthur. Their craftsmanship, professionalism, and skill were exceptional, and they were an absolute pleasure to work with. We truly appreciate everything they did to bring this project to life. 👏😊🐾
Superior Basement waterproofed my garage where water was seeping in from the back wall. The crew arrived on time, explained what was to be done, worked efficiently, cleaned up when done, and showed me their completed job. The back wall was waterproofed, the 3 foot cinder block wall was sealed, and that night we had heavy rain. My garage was completely dry the next morning. I highly recommend this company for its fair pricing, efficiency and professionalism. Thank you, Angelo and your team. W. Corris Stratford, CT
Had some water in the basement for the 1st time since I moved. Had the damage assessed, quoted and completed in less than 10 days. Not only did they seal the inside of garage, they also did the outside wall. They did a fantastic job. Very professional and knowledgeable. Definitely recommend their services.
I had a fantastic experience with Superior Basements for waterproofing my basement. Their team was really professional from the get-go, responsive to my inquiries, and patient with all my questions. They did an excellent job fixing up my basement and installation of drainage system. I highly recommend this company for their service and quality workmanship.
Super professional from start to finish. I can’t believe the difference we have soooo much more space now. Highly recommend.
