1 A well-maintained residential marble floor might start to show some signs of wear in 2-4 years, and will need to be professionally honed and polished at cost of about $2.50-$3 a square foot, with a minimum charge of $400-$500 for a single grind and polish. Professional installation of marble flooring starts around $9-$20 a square foot (materials and labor), or $900-$2,000 for installing a marble tile floor in a 100-square-foot foyer.
