This theme is all to familiar, (any one can tile) yes anyone can tile but it takes years of hard work to perfect the art. The public should be warned about the cowboy element in this industry. Tiling when done right is a thing of beauty, I shudder when I see this kind of work.
Having spent my whole life as a professional tiler in every conceivable aspect of the trade, I find these would be wannabe tilers an insult. Tiling is a very highly skilled job imo, so looking at these poor efforts, makes my blood boil.
If people do their research and source a good tiler. They will be very happy with the result, unfortunately there will always be the cowboy who comes along and talks a good job. If I price a job that is not a recommendation I try to instill some confidence in the potential client by saying" I don't want you to be happy with my work" "I want you to be ecstatic" if you are not don't pay me. To date I have never had anyone not pay me. I do my job, nothing more, nothing less. I am a tiler.
