John's company, constructed a bathroom in a downstairs room, building a fake floor to accommodate the pipes. They were able to begin work sooner than expected. The framing went very quickly. They had to drill through a concrete wall for the outgoing pipe and for the incoming water. They did a veryimpressive job. They built a flower box to help disguise the pipe. They hand dug the trench to the septic tank, going under a sidewalk without damage. They installed a toilet, vanity, and tub. They tiled the floor and the wall of the tub/shower unit. They finished the job when they had expected to do so.Their work is very professional. I was very satisfied with the result. I would hire them again. I highly recommend JLB Construction.
