Lupien Jean Plumbing

We had a laundry tub installed right beside the hot water tank. When the plumber left, we both agreed he had worked 3 hours at $81.50 and hour. I offered to pay right away but he said his wife does the billing. When I got the bill came up to $528.99, including $326 for 4 hours instead of $244.50. We were planning to have more work done but we will hire someone else. The laundry sink works well but some of the water does not fully drain unless I drain it manually.
