I discovered Guardian through Yelp when I was interviewing Pool Cleaning Service Companies. Lance impressed me immediately with his knowledge about chemicals and pool water analysis. He was able to determine quickly that the problem with my pool water was unbalanced chemicals causing algae growth. Within a couple of weeks of their great service I couldn't believe the difference in the quality of my pool water. These guys have always been upfront and honest with me when additional repairs were required and their prices are reasonable, as well as they have gone above and beyond the call of duty if special circumstances demanded it. Guardian is everything you look for when hiring a great service company. They have been, honest, upfront, knowledgeable& dependable. I highly recommend them
