I can't praise this outfit enough, unclogging my upstairs kitchen sink drain that has turns around a window below in the wall. Years earlier had the same clog, plumber tried snaking, couldn't do, used Sawzall on ceiling below to replace drain pipe. Was left with hiring a plaster repairer & painter.
This plumber did not give up snaking, used different heads, a lot of effort & elbow grease & went out all 25 ft. Sink drains fine now.
