I was away and my brother-in-law called and let me know there was issues with the toilet backing up - he mistakenly called Roto Rooter - I asked him to call a similarly named company.
Anyways - they snaked the drain and informed him that the clay pipe had collapsed and it needed to be repaired immediately ('We can start tomorrow! - for $3000) ... I told him to pay the guy and tell him we'd get back to him.
Basically called another company and they came in with the camera and said the drain was cleared of roots - and it was not collapsed. Would it have to be replaced? Eventually - but it was nowhere near a collapse.
And when I called Roto Rooter to complain - they did nothing. They never even returned my call. Nice. I would NEVER recommend them.
