"We are in the process of having both our dirty & clean water lines completely changed, which is a huge project. Several of the great Service Champion technicians have had to dig huge holes & long trenches, with the additional obstacle of having to cut through huge roots, from an enormous tree in front of our house, that have literally taking over our front yard & destroyed the pipes. They also cut through cement & even â  jackhammeredâ  through an enormous patch of concrete that was about a foot deep, which took a lot of time & muscle to remove! This was definitely an amazing example of â  good deeds for freeâ  . We had so many different, excellent technicians coming & going, who did a tremendous job for us, but I unfortunately cannot remember everybodyâ  s names. There are two guys who actually have been working at our house the most, so Iâ  d like to recognize them (big Chris & Ryan). They are both terrific examples of the Service Champions model, and are excellent in their trade! They have worked very hard & have been a great help in so many different ways, helping to make this difficult process much easier for our family! Kudos & our deepest thanks to Chris & Ryan & all the great Service Champions professionals! We sincerely appreciate you all!"
