First, let me say my marble floors are shiny and better. Now the bad. The main guy is a salesman and will say anything you want to hear. His workers were great, however.
He spent 20 min looking, measuring and quoting my marble floors & granite counter tops. When his workers arrived, they knew immediately (like in 30 secs) the floors had a coating on them that needed to be removed. They also told me the counter tops (which were new) could not be shiner because factory polishers are heavier.
When complete, my carpet was stained, grout dirty (see pics) and counter tops looked the same. In fairness, he probably would have fixed the carpet, but i just don't want him back in my house.
Tip: its seems to me that most floor companies in Vegas charge about $1.50-$1.75 per square foot to clean and polish, fyi.
