I am patching up the chimney on my house. It wasn't born with a damper, so the heat goes straight up the flue and bye bye.
Fireplace inserts are expensive, and because the fireplace is a unique Mjollnir shape, an insert would not fit.
But they do have chimney cap/spark arrestors with built-in dampers, and I have one on order.
It seems that the current chimney cap/spark arrestor was not mounted on a flue liner. The chimney does not have a flue liner at the top. I am (more than) guessing it was destroyed in the Loma Prieta earthquake and the former owner patched it together best as he could.
So I got a flue liner, muscled it up onto the roof, chiseled the bricks so it fit in place. Nice.
It needs some mortar. Will any cement/mortar work or do I need heat-resistant stuff? Do they have this at The Home Despot?
