5 STARS! Pool Knights watched our pool while on vacation and I cannot give them enough praise! The Knights provided emailed photos of each visit along with a written report of the chemical status. Why doesn’t everyone do this?? The pool was in fabulous shape when we got back. All this was done at a competitive price. There were no hidden charges! Chemicals needed were included. We will use Pool Knights when we need a great pool company to take care of anything with our pool!
