Five years after Stefano and his team sealed a family's marble kitchen counters, that recent customer reported no red sauce stains, red wine stains or etching, and had Stefano and Tony come back to reseal the kitchen counters. Final Seal Pros protects and refinishes stone countertops, and holds 5 stars from 58 Google ratings and 5.0 stars from 4 ratings on Houzz. A recent customer said their marble countertops were protected and the finished stone looks natural. A 2026 customer said Stefano, the owner, applied a protective film to one type of stone and a nano ceramic coating to another on new countertops, and that liquids no longer soak in. A 2026 customer with Dolomite counters said Stephano refinished them. In a 2024 review, a customer said Stefano installed Stoneguard on a Dolomite Quartz table with Tim. A 2024 customer said Stefano and Tim sealed the marble top of a kitchen island. A 2024 customer said the coating evened out the finish on honed quartzite. A 2022 customer said Stefano and his team sealed granite and marble countertops. In a 2018 Houzz review, a customer said Stefano came out to explain a few solutions and estimates for grimy new granite countertops, applied a nano-coating, and later came back to do the stainless appliances and bathrooms. A 2024 Reddit comment in r/CounterTops said Final Seal Pros is out of Boston and uses pro grade nano products. The company describes its work on Houzz as countertop protection, restoration and refinishing for natural stone, glass and metal.

We used Stefano and his team to seal our marble countertops 5 years ago when we did our kitchen and bath remodel. We were told by others to avoid marble because of the risk of staining and etching. However, then we found Stefano and Final Seals Pro and they were able to provide a product that provided full protection without taking away from the natural beauty of the marble. The protective seal did exactly what Stefano promised it would. After five years of countless meals with small kids and a puppy, we have no red sauce stains, red wine stains, etching, etc. Our kitchen counters only had the normal wear and tear of countless dishes on them, so we just had Stefano and Tony come back after five years and reseal our kitchen counters and now they look brand new again (and we didn’t need to touch the bathroom vanity which has minimal wear and tear after five years). Stefano and Tony are very professional, prompt, clean and courteous. They spent the time explaining exactly what they were doing and what to except, etc. I highly recommend Final Seals Pros.
We had an excellent experience with Final Seal Pros! Stefano was fantastic to work with—friendly, professional, easy to talk to, and happy to answer all of our questions throughout the process. We recently had our marble countertops protected, and it has given us so much peace of mind. Knowing we don't have to constantly worry about etching or staining has made such a difference, especially in a busy family kitchen. The finished product looks completely natural, and you would never know there is a protective treatment on the stone. From start to finish, the process was seamless, and Stefano made everything easy. We couldn't be happier with the results and would highly recommend Final Seal Pros to anyone looking to protect their natural stone.
Stephano was very knowledgeable and professional . Our counter tops are Dolomite which are a combo stone of granite, quartz, and marble . They are a bit tricky to refinish but Stephano ‘s knowledge allowed him to refinance them with ease and perfection . We are very pleased and satisfied . TY very much . Jeff and Janet
It's hard to add much beyond what has already been written about Final Seal Pros, Stefano the owner, and his team. We had issues with the new stone countertops we had installed in our new home, and Stefano came to the rescue with what certainly appears to be a truly definitive solution for those seeking a robust countertop finish. Our countertops now appear resistant to staining, as anything that gets on the countertops remains suspended and doesn't permeate the surface of the stone. In other words, water and other liquids like oils or grease no longer soak into the stone leaving a stain. Rather, the contaminants remain suspended in one case by the protective film he applied to the stone, and in the other by the Nano technology ceramic coating he applied. Two different processes he offered us for two different types of stones we have. Both provide what appears to be an exceptional barrier to the stone to keep contaminants from soaking into the surface and leaving stains. Stefano is a great communicator and he kept us in the loop from beginning to end. My only regret is that I didn't have him do this the moment the stone countertops were installed. (In a perfect world, all stone countertops would be installed with the solutions Stefano offers.) It makes keeping the countertops looking like brand new, no matter how much you use them for cooking, cleaning, etc. The protective film is seemingly perfectly translucent making it invisible to see when applied and it retains the beauty of the stone when he's done. An added benefit to the nano ceramic coating is that it helped enhance the color of the stone, evening out and enriching how the countertops appear. It was an added bonus we hadn't anticipated, but certainly adds icing to the cake. Bottom line: Would I do it again? Absolutely.
My wife and I agreed Stefano is one of the best contractors/people we have ever worked with. Stefano takes the time to explain and educate what he is doing and why. He is professional, knowledgeable and very easy to speak with. We highly recommend him on your project. A sidenote he was a auto service manager in his previous endeavors and took the time to recommend service on our car as he walked through the garage.
