The pool is about 24 years old and I was looking to have its interior resurfaced. I've called six different places. Anthony & Sylvan came out and they were the most knowledgeable. They knew exactly what I was talking about when I was telling things and they were able to do the job without any issues. They completely replaced all the tiles and re-plastered the inside and it came out beautifully. They did everything they told me and it was done quickly. I just stayed out of the way and they took care of it. The newly renovated pool is so easy to maintain. I just drop this robot that does the inside of the pool and keeps it beautifully cleaned. Then two hours later, I take it out and the pool is ready to swim in.
