Could you please recommend a trustworthy person or company in Las Vegas NV to face polish some hazy spots on my tiles. They are located on a fireplace hearth and I tried to fix some scratches and nicks with sandpaper. I only went up to 1500 and I'm getting tired. I need a pro to come in and finish the job. I know it won't polish like new but I'll accept what a pro can accomplish. The fireplace is in a darker area and a small variation will never be noticed. By the way the tile was installed last week.
