Well, I have officially decided it's time to do something about the portion of my chimney that extends above the roof line. Portions of my temporary crown fix have already fallen off and I know some of the bricks are spalling. I'm looking into my options, but here is what I'm really contemplating doing.
Completely remove the junky crown that is currently on and replace it with a precast piece.
Coat/cover the exterior of the bricks with cement/mortar to seal any cracks and prevent further crumbling.
Install stone veneer over the outside of the bricks that I coated.
Seal up any gaps between the veneer and flashing and crown with silicone.
What do you guys think? I think I've also convinced myself to dump some insulation down around the liner. Not sure how much I'll actually get down, as it's a tight fit, but it shouldn't cost much and whatever I fit in won't hurt anything.
