No prob, learned that lesson from fixing people’s chimneys. Oh there’s only a couple of bricks loose. Just patch it up and good. No my name is on that chimney and if it burns your house down fingers will point at me. So with out even looking it’s a grand possibility less but I’m going to say a grand. Because you don’t know what’s there till you take it down, even if I went and inspected it hidden issues. But my expertise is what your paying for and it cost me a lot need to recoup some of that.
