 just to repair a crack. But the other things that you're talking about are all entirely expected. You know, having to repoint some mortar, having to repair a cracked chimney cap, a concrete cap around the chimney. Those are all normal. I don't necessarily think that putting a sealer on is going to have that much of a major effect of slowing down any further deterioration. I think it's just sort of wear and tear. Okay. And so if it's not vapor permeable, it could even harm it.
