I had changed pool companies every few months until I found Pool Daddy. When I called and explained my complaints with the precious companies Kimberly called those companies "Salas and Dash" and promised that wouldn't happen with Pool Daddy. That has been almost a year ago and we have been very happy with the service. We live where there is a lot of calcium so I still get build up on my spillway but not on the surround of my pool.I highly recommend this company! Billing is simple - can be online which I use or send in a check. Customer service is superb with friendly, gregarious Kimberly. I am satisfied with paying $90 a month for service.
