Roto-Rooter Plumbing & Water Cleanup

This review is for the administration of this company. We were having backup issues at our home, technicians came out, snaked the line and still had a blockage. The camera guy came out and told us that we would have to dig up and replace the main line running out into the yard because it had either collapsed or been taken over by tree roots. The quote was for $10k. I find out from my neighbor that there had already been main line work done prior to us buying the home 5 years ago. I called up RR and asked if I could get the information of the work that had previously been done. They told me they couldn't give that information because it was a violation of privacy! This is MY house I need information on, not the previous owner or the amount they paid for anything. I own a construction company and if a homeowner inquired about any work we did I would ABSOLUTELY tell them!! This just makes me think they want me to pay more money for something that's already been done. I asked the manager if they would ever tell me if the work had been done or if they would just have me pay twice and she said oh no we would be honest. Yea right!! That's what I was asking for!!!! I am astounded that this company's policy states that information of any work they previously did on a home cannot be shared with the new home owners! Outrageous!
