Feedback from Our Satisfied Customers

“I was expanding my kitchen and was looking for a specific Caesar Stone color to match my existing counters. I called several fabricators and was running out of hope since the people I dealt with weren’t too willing to help. The BEST call I made was to GranMarb, I was helped by Michael who took down all my information and actually returned my call promptly with great news. GranMarb worked diligently to get my slab cut and ready in time for the Thanksgiving Holiday. While visiting the massive showroom I met with Michael and Giovanni who were very welcoming and attentive. Great customer service, full of friendly advise, ideas and selections. My finish quartz is a work of perfection, I am beyond satisfied with the GrandMarb experience from start to finish. I highly recommend you use GranMarb on your next bath or kitchen project. It was such a pleasure to deal with this punctual and professional company.”

“I researched this company on the internet after visiting other granite installers, including leaving a deposit. Thoroughly impressed with the customer service of Michael, owner Giovanni, the price and modern innovation, I left a deposit. The template completed by Anthony via computer laser, therefore the granite installation is perfect with lack of seams, butts up to walls and cabinets. My contractor Mike Callahan was so impressed, he left with GranMarb business cards. Each person that enters my kitchen asks “who did this granite installation as it is incredible. Still under construction, I recommend 100% to all I meet. Use this company if you want a perfect installation and the nicest, helpful people.”

“Granmarbinc has is Long Island’s best Granite Counter-top store by far. When we went into the showroom I was amazed when I saw all the Granite & Marble on the walls & floors. Granmarbinc has a beautiful marble & Granite floor medallion in the center of their showroom where it circles into a 100% all Granite Island Table. The showroom was just the beginning, after I met with the owner Giovanni he gave me a tour of the Granite Yard and after we picked out our Granite color Giovanni showed us their granite cutting waterjet which blew us away. Granmarbinc does everything from measuring, fabricating, installing and the service is so amazing. I will recommend only Granmarbinc to all of my family, friends and associates because it actually makes the process exciting and when you go to Granmarbinc you will understand why we are saying they are the best Granite & Marble store on Long Island by far.”

“Granmarbinc worked on a mutual client of mine with their Granite Kitchen Counters, Marble Floors & Marble Bathrooms. As a locksmith I had to cut a perfect circle in the marble for the lock into the marble. Granmarbinc was their with me and even though my cut came out perfect into the marble Granmarbinc assured me that if any of the marble cracked or chipped they would replace that which was so uncommon to hear another business help another these days. Thanks Granmarbinc for being a great business for the customers & businesses on Long Island.”
