I can't recommend the folks at United Marble enough. We found ourselves in a time sensitive bind and United Marble saved the day. The quality of work was amazing and turn around was super fast. The team was so responsive and helped us trouble shoot along the way.

Terrible install service despite being assured many times they could complete this job. Paid top dollar for absolutely terrible install. The Stone was gorgeous and I trusted the wrong company to work with it. Don't make the same mistake. After seeing pictures they didn't even have the decency to offer any compensation.

Report
When I met John and the crew at United Marble I was so glad to finally have found a high-end marble company with the capability to execute my projects with precision and efficiency. They have a HUGE selection on slabs on site. The only other place we found that had on site slab selection was a large shop, where my project would just be treated as a number among other jobs. I've been in the industry a long time, and I know that with the type of projects we complete it is impossible for a large marble company like that to give my projects the attention to detail they deserve. United Marble has the staff, equipment, material and knowledge to knock it out of the park time and time again. I wouldn't go anywhere else.
