First of all the houses 22 years old. Ben was the first plumber that arrived to check out the problem with my kitchen sink backing up. He ran the cameras Down the sink drain and saw a clog at around 18 feet down the way. We discussed the solution, the price and the next person that would come out this afternoon to do a Jet system clean out. Within an hour, Brian arrived, and he explained what he was going to do. He was very thorough. It took him about an hour and a half, and he explained and showed me the pictures that he took with the camera. He showed me where the grease build up was and the cleaned pipe. Both of them were very courteous , respectful and great communicators. I highly recommend this company. This is my second time using this company.
