What is the average price per square foot for stripping wax from a wood floor?

That depends on where you are, Here in California, S.F., It cost $4.25 per sq. ft. to refinish a wood floor. And being that it has a wax finish, it can cost more because the floor contractor might have to use extra steps to get that wax finish off. That is my profession, and wax is one floor I hate to refinish. Like I said before, it depends on where you are.
