 No, no, no, this is good. The very top of the chimney where the flues come out of the masonry, they'll pack mortar around that at the top and they'll pitch it and they'll make it like a little roof. So when water hits on that, it'll run off and it runs down the chimney. Well, what happens is it's mortar most of the time and that it tends to crack and split open. You don't see it. I mean, how many people actually see it unless you have a drone?
