I had two issues that I had Zurn look at. One was a leak in our garage. The repair person did a good job of identifying and fixing the problem. However, I felt the amount charged for the work done was out of line. But the work was done fast and seems to be fine.
At the same time, one of the Zurns (a son I think) came out to give me an estimate for some work I was interested in doing. Granted I didn't have all the specifics but I would assume they had done similar work and could have given me a high-level estimate, knowing it would have to be revised. He also said he would email me some plumbing supply centers where we could look at products. I never head from him again.
When I received a follow up post card asking about the service, I returned it with my concerns and never heard from them again.
