Yeah amish and mennonite generally do work cheap. But like all contractors there are good ones and there are bad ones. And the good ones usually cost more. We have a mennonite chimney guy near us. He is really cheap. But he drops unlisted un insulated liners and doesnt clean the chimney first. So yes he is cheaper but he is using cheaper materials and doing half the work.
We do have people who do great work for very reasonable prices here in Pa ,the amish. I dont think i could find anyone to do that Job for $500. Perhaps tear down the chimney but not he rest of it. Most of the contracters wont even come out and look at a $500 job.
Since we’re still in the rabbit hole and the op is mia, let’s keep talking about contractor pricing, value, and making sure you know what you’re buying!
When I had my single story masonry chimney torn down and removed by a licensed, bonded, insured professional for 500$ it was a good deal I thought. Couple guys all day doing menial demolition labor. The roof hole for this single flue was pretty small and required patching. That guy was also a licensed, bonded, professional. I had the shingles and previously had him roof my house so he only charged me like 30$.
Perhaps the most important part of this story is that it happened about 10-11 years ago during the Great Recession or whatever they called it. The labor market was soft and that certainly helped.
This was just my experience and the valuable part of the story isn’t the 500$ but that the op would be wise to consider demolition as one of the options. Especially if the next issue will be whether this masonry chimney is even safe to use due to so many other possible deficiencies.
