The estimate broke down materials, listing specific fittings, etc. needed. The labor on the estimate did not state $50 /hr. specifically, but the quantity listed was 40, and the total labor estimate was $2,000. Any reasonable person would infer 40 hrs. @ $50 /hr. from it.
Actually, the bill is an exact copy of the estimate. In fact, it includes fittings and copper that were never used in the job. I find it hard to understand how I can be billed legitimately for things that were not part of the job -- materials OR labor.
I have not paid the bill yet, and I have not talked to them yet. I'm looking for a leg to stand on if/when I question their bill.
