Most recently, St Paul Pipeworks replaced some corroded piping in our house for the tub. They seemed to do a good job. It was messy work, and they were concerned that they might have to open up the walls in our 100-year-old house, but they were able to get at it from the basement, which pleased us. It didn't seem to take an inordinate amount of time. The plumbers from St Paul Pipeworks were in and out in one day.
