We hired a contractor to install new tiles and also resurface our pool.
Today is the first day of re-tile job and i guess that comes before the pool resurfacing job. I noticed that he's sanding on top of our existing tiles, rather than removing them, and planning on putting new tiles over them.
Is this the norm? This company has done jobs for our other neighbors and have gotten good reviews, this decision to tile over tile surprised us a bit..
