cracks on chimney cap
I had the top section of my chimney re-bricked and a new chimney cap built. A month or so after the work was done I went up and noticed the cap had a bunch of cracks in it. I immediately complained to the mason, he looked at it and said the cracks were normal. He said they weren't a problem because they didn't extend all the way through. I am thinking that water will get in there, freeze and expand, and very soon I'll have a ruined chimney. Are cracks considered normal and satisfactory work?
