Had a burst pipe that needed to be repaired. Received an estimate from S&K with a low and a high range separated by $100. They did the job, never mentioned any issues or complications, and then gave me a final invoice for 33% OVER the high end of their estimate claiming it took longer than they estimated. Well, sorry, but that kind of increase should have been discussed with me. Since it wasn't, Servizzi and Knabe should have eaten AT LEAST half of the overage. When given the opportunity to do so, they said nothing. It's a shame because they were very nice, and it seems, did fine work. But 33% over the estimate was a slap in the face.
