Hello Highland Park neighbors, I have what appears to be a clogged main sewer line on an older (60+ years) property. There is a TV ad that runs pretty often for a big local plumbing company that offers a "$99 Drain/Sewer Cleaning Service". Does anyone have any experience with this cheap/flat rate service offering good or bad? Better yet, does anyone have a GOOD experience with a local plumbing company who shows up on time, with the right people and (modern) equipment to diagnose and quickly unclog/fix a pesky main sewer line, and charges an honest price for services rendered? Thanks, Joel
