Had sewage backing up into house. They ran a Roto-Router through house sewage pipes for $250, then referred us to city sewage services when additional blockage found on city property as sewage began flowing onto street in front of house. I asked for help and so they coached me until successfully contacted city sewage services after hours. The city man was true professional. He cut a tree root blocking a joint under sidewalk, cleaned up street sewage, and asked whether the plumber charged us. I said, "No," but began to wonder whether blockage had been street all along. 3 stars because high charge

PLEASE DO NOT CALL THIS COMPANY!! If I could give zero stars, I would. The answering service was overly friendly and a technician came out. We needed a hose bib (tap) replaced in the backyard. All the plumber needed to do was to remove the old one and screw on the new hose bib. The technician made a big show about taking pictures of the existing hose bib and sending it to the manager. The manager's diagnosis was to cut off the metal portion of the pipe and solder on a new one. He claimed that someone had tried to replace the bib earlier. Charges were going to be a whopping $475!!! It was

I would rate this zero stars if I could. I've made 2 appointments with them on consecutive days and they didn't show up either time. Don't waste your time booking a visit from these clowns.

My advice, get a second quote from another company. I wish I had taken my own advice but my tenant had been without hot water for a couple of days and I felt that this was an emergency (more on that later). The work took place on a weekday, during normal working hours, and it was a fairly straight forward job to replace the water heater. In fact, the job was finished four hours after the technician arrived. So far, so good. The quote for the materials was high, but within reason. Here is where the fun starts. I thought that the quote for labor was an estimate, based on the job taking a full day
