My tile man was in the process of installing a herringbone backsplash in a customer’s kitchen. I checked on his progress and discovered that he had made an error, and the complicated pattern wouldn’t be even on both sides. We could have continued and it is likely that the customer would have been OK with the result. However, I was not. The only solution was to remove the existing tiles and redo the job. It took longer, but it was necessary to get what I considered to be an acceptable job. The advantage of having a contractor on the job is that they take over the responsibility of supervising workers and subcontractors.

I had my tile man remove all of the tiles that he had installed as the two edges were not even.
The job redone. You can see that tiles are now centered on the wall between the two cabinets.
