I had a wonderful experience dealing with Quality Granite and Marble in Denville. Joanna, who runs the showroom, was very helpful, and gave me a quote in less than 15 minutes for a Silestone quartz countertop I had already chosen. The price was the most competitive vs two other countertop vendors I had also visited. I also had to wait much longer (several days) for quotes from the competitors.
When it was time for templating the kitchen island, Joanna's husband, Ziggy, showed up at the exact time we scheduled, and he did a digital template in about 20 minutes.
One week later, Ziggy came back with an assistant, and installed the 800 lb. quartz countertop, as well as drill out the hole for our faucet. Afterwards, he cleaned up the entire area before leaving.
They were professional, courteous, and on time with everything they committed to in advance. I would highly recommend Quality Stone and Granite for your projects.
