 Good morning Joe, I want to thank you for your prompt service on my new pool pump installation. As we have a big weekend coming up with the fourth of July and needed the pool clear blue and not green for the BBQ. Your crew was very professional and on time, and left the area better than when they arrived. Again can't thank you enough for saving this weekend and you will have all my business when electrical, plumbing and HVAC needs arise. Happy 4th of July! Rogers Serpas, Jr.
