I contacted Pipe-Con Contracting Inc. and they promptly came out and provided a very reasonable quote and did a full explanation of the sewer backup valve and rebate program provided by the city. He did not pressure us in any way but was pleasant and very informative. I contacted him back and he agreed to come back that evening and finalize the contract. They started the work the next day and were quite neat, kept any and all overall disruption to us to a minimum. I would recommend is services to anyone.
