Q. What is the average price for stone restoration?
 
A. There are so many variables that will factor into the equation that it would be impossible to answer with any blanket statement. Does the surface need to be ground? Honed? Polished? Is it one large open area or are there small hallways to maneuver? Is it a very small area or a very large area or somewhere in between? A larger unobstructed area will be less per square foot than a smaller area, especially if there are many corners, etc.

Your best bet is to find 2 or 3 reputable contractors and have them bid on the job.
