we are very satisfied with the 90 plus feet of sewer line you lined with your fiberglass epoxy re-lineing system. all of your employees were experts at their jobs. they explained the different procedures and answered all our questions. the workplace was kept clean and neat. no trenching inside the house like the first 16 ft repair with piles of dirt.i wish we had known about your system sooner. we wILL recommend Nu Flow to anyone with old cast iron sewer line problems. THANK YOU.
