All tile work is not created equal, and I have certainly seen poor quality work in customer’s homes. My tile man, Joe, has 20 years of experience and a lot of natural skill.
It is not uncommon to create a mess when tiling. Messy glue application and hurried work can lead to imprecise results. Joe keeps his workplace clean and organized. He can clearly see his progress and make adjustments to keep the tile pattern interesting and randomized.
Natural tiles are not made in a factory and so there will be imperfections in any tile job. However, these imperfections are minimized when a tile man is really a tile artist.
