Beware ! Sendtko and Shaw Flooring cost me hundreds of dollars to repair a huge mistake they made during my marble installation. Several professional installers have told me everyone (who knows what they're doing) knows to not do what they did. After they messed up my floors, they agreed to pay for the repairs, then later backed out and paid nothing. Please don't risk your floor tile or marble installation with them as I did, unfortunately. Terrible !
