Best Maintenance Programs in Minneapolis MN

We had a pipe leak over the weekend. approx $200 just to come out and diagnose problem (fair). It was a pinhole leak that was present for over a day so the leak looked worse than it was. Standard copper pipe, 10 feet of replacement with standard fittings, 100% visible/ accessible. service was fine but he charged 1600 dollars! Didn't tell me how much more the service would be until after he performed the repair and tried to tell me he was giving me a discount. I felt compelled to pay because we were in a bind but I think this situation should be visible to other potential customers so they can make up their own minds about ethics and pricing.
