Holmes on Homes (2003)

Season 5: Episode 10

Janet and her elderly mother, Audrey, upgraded their vinyl kitchen floor to ceramic tile. Shortly after the work was completed, they noticed hairline cracks through the centre of the tiles. The flooring contractor explained it wasn't his fault, and that the weak structure of their home was shifting and causing the floor to crack. But the cracks were forming through the ceramic tile, and not along the grout lines- the weakest part of a tile floor. Mike and the team put on their investigative hard hats and get to the bottom of this tile flooring issue.
