  • I was thoroughly impressed with the installation process of my bathroom vanity. The installers were efficient and courteous. I appreciated that they used tarps and floor coverings to protect my hardwood floors. Overall I am very pleased with my new granite vanity top.

  • We recently did a total kitchen refresh and used Optimum for our Cambria Quartz Counters. We went with the thick 2" version and are so happy we did. The entire team was so easy to work with and always on time. Everything was measured perfectly, and the installation was exactly as explained. I highly recommend, 5 stars.

  • Optimum Granite & Marble just installed our beautiful quartz kitchen countertops today. They just left and did an amazing job! A+ in the assortment of product they carry, A+ in communication to ensure expectations were met, A+ in installation cleanliness and courtesy and going the "Extra Mile"! They showed up on time and were very efficient - you can tell they use skilled workers. Kudos to the owner who showed up to help with the install because we had many angle corners and he wanted to make sure things turned out perfectly. I did my research and they are not the most expensive nor are they the cheapest, they were fairly priced and gave us peace of mind that we were in good hands. Today's installation was evidence of the owner being "hands on" and this filters down to all the folks I interacted with throughout the process. I highly recommend Optimum Granite & Marble.

  • The team at Optimum Granite were great to work with-from the visit to the showroom to the installation of my Master bath two sink granite. Price was very reasonable. As I had a very long slab I wanted to avoid a seam and my sales rep and her team made it work. I am delighted with the piece and that the sinks were included. They delivered the day they scheduled-no delay even though the original piece became damaged the night before and they had to re cut mine the same morning. Professional every step of the process. I will use them again and highly recommend you see what they have to offer! My husband is a realtor and will recommend them to clients as well.
