Yes, get someone else to look at it. We moved in June and our woodstove failed the WETT certification from one company, and passed it with another. It was all really, really minor details that failed it from the first guy, and he didn't know what he was looking at either. I tried to tell him what was going on, but he knew everything there is to know about this stuff, so I just told him to take his quote and burn it.
We're up an running now, its great.
