Called roto rooter for a house main drain clog. Technician came and cleared the clog in 5 mins then charged me $240. He did not clean the entire line like he should have for that price. Drain backed up a second time within 2 days. Another tech came cleared the clog and said he would send a camera guy to inspect the line the following day. Camera guy cancelled first time and didn't even show up second time. Technicians were friendly but you must realize they work on commissions. Call a local plumber instead.
