DiamondKote fixes and coats concrete: pool decks, garage floors, basement floors and front steps. Its Houzz profile says it is a division of AMT Enterprises, LLC based in Middletown, CT, working since 1999. A recent customer said the company removed cracked concrete near rusted rebar, then patched, bonded, coated and sealed heavily pitted front steps, left the site clean and emailed care instructions. A recent customer had an entire basement floor acid stained and said it came out exactly as imagined. A 2025 customer said DiamondKote resurfaced their 30-year-old pool deck for the second time in 5 years, with everything done in one day. A 2025 reviewer wrote that their stamped cement was ground down and refinished in 2015, and that 10 years later Mike and his crew returned to repair cracks and repaint the pool deck light grey. A 2024 customer said the pool deck job took longer than they expected and that all their uneven areas were leveled. A 2023 customer said Mike and his team ground a garage floor, filled holes and applied an epoxy coating and chip system in one day. A 2024 reviewer who said they own North Cove Construction in Old Saybrook wrote that Mike has installed epoxy floors for them for over ten years. A 2021 customer wrote that Mike yelled at them for asking too many questions, and quoted an email from him calling their job very small and not profitable and saying he was no longer interested.

We recently had DiamondKote sprayed around the foundation of our business building, and we couldn’t be happier with the results. The installation crew was amazing, professional, punctual, and great to work with. They kept the work area clean and did a fantastic job. Highly recommend them!
I highly recommend DiamondKote. Mike and his team did a great job. They were professional and on schedule. Mike always responded promptly to any questions. Love my new floor!
DK removed cracked concrete near rusted rebar and patched, then bonded, coated, and sealed our heavily pitted front steps. They knew exactly what needed to be done and how deep to go with the rebar removal. Did exactly what they planned to do and left the site clean and emailed detailed instructions on care and maintenance. I highly recommend them. They did a fantastic job!
We could not be happier with the pool resurfacing job Mike & his crew did for us. They are very professional, hard working and clean up when finished. We would highly recommend.
Best floor ever! We had our entire basement floor acid stained, hoping for a very particular aesthetic which is not easy due to how unpredictable acid staining is. It came out exactly how we’d imagined it! Mike and the guys crushed it!
