I just got my chimney inspected with a video inspection. The house was built in 1940 and the inspection showed that the flue has clay liners that are in perfect shape (no cracks, no creosote, still orange in most places).
The only issue that the inspection showed was that the mortar joint between the clay liners had gaps, possibly from water eroding the cement (the chimney is not capped, so we will definitely be doing that).
I plan on having no more than 10 very tame aesthetic fires a year (2-logs) with very good seasoned wood (which I believe produces less creosote).
From a safety perspective, is it necessary to pay the $1500-3000 to have those cracks sealed?
Thanks for any input!
