I am 84 years old. Without hot water for a week until I called Leak Detection. These three young men were extremely professional in every way. My problem turned out to be bigger then I even anticipated. These three seemed to know just how to solve it. I am so grateful to them for bringing my life back to normal. I shall spread the word about this company and these three fellas. Please, see that they know how much I appreciate them and what they did for me.

Thank you to all for your help, expertise and professionalism. This problem is slightly unusual because a leak wasn't found in any of the lines yet the pool lost 5 inches of water when the pool motor was running. Tomorrow will be the first day in over a week that the pool will cycle through. Will continue to monitor water level. Greg was super, very knowledgeable, thorough in his testing and professional in his attitude. Alayna, Rebecca and Sean also were most helpful, friendly and professional when I called the office. I would highly recommend American Leak Detection.
