We contracted Canyon Plumbing to remove the Poly B piping from our home and replace it with Pex. They gave us a fixed price quote. They showed up on time, worked longer hours when necessary so we would have water at night and did a very professional job. The most important thing was that they cut a minimum of holes to access the old piping connections. They had some unexpected difficulties but solved the problems and never once asked for extra funds. Clean up was a little slack but the job was well worth the price.
