"Super quick and responsive when scheduling the service. Although he didnâ t know about it before hand, he was actually able to move the whole spigot to the other side of the house and barely charged me more. Will definitely have him back in the future when more projects arise."

"James Slaven was very courteous, clean, and professional. After evaluating the spigots that we thought needed replacement, he actually talked us out of replacing and at no charge tightened it up & told us to watch for any future leaks. He did replace one spigot and installed a toilet. We will definitely call on him again."

"They were very professional and understood the water problems for East Tennessee. We had a 3rd party water test and had talked to a few other professionals before we selected Advanced Water. So we had some knowledge. AWS was good to work with and we have ready recommended them to others."

"Thomas arrived on time and worked efficiently. He was very nice and polite. He installed the new water heater and noticed something seemed wrong once the pilot light was not working correctly. He called the company and discovered that it had a defective part. Thomas removed it, returned it, and came right back with a new water heater which worked well. It must have been frustrating for him, although he was very professional. I can’t express strongly enough that I would definitely have him do future repairs if needed!!"
