Gannon installed our pool 16 years ago. We have never had anything major go wrong, just typical wear and tear over the years on heater, liner, etc. When we do have issues, they are always addressed in a timely fashion… and it’s usually 4th of July pool party season! Kudo’s to Gannon for a great product and great customer service! We appreciate all you’ve done for us over these 16 years! We look forward to another 16!
