I am installing porcelain tile throughout my entire house which is a large job. unlike installing carpet through the house, 20" tiles require a flat and level surface. The concrete slabs were uneven and required leveling. Most companies would walk away from a job like that. Shane with JW Floor Covering has done an outstanding job in correcting this issue and is proceeding with the installation. Shane has done an amazing job and is a perfectionist, I have no doubt that I have made the right selection in choosing JW and am very lucky to have Shane doing my installation.
