Another long time lurker who's found good information here, and now having recently had a Buck 91 insert installed, needing to go from lurking to asking. There were a couple of hiccups with the install, and the installers will be coming a week from now to remove the liner and fully insulate and properly reconnect to the stove. After the stove was installed, I was preparing to install a block off plate and realized the chimney was leaking. Today while putting a tarp over the chimney, I decided to take the top off the chimney cap to check some measurements, and looked inside the pipe and looks like it may have been damaged during the install. Based on the picture, is it still usable? Was planning on sending pictures to the install manager tomorrow anyway, but figured I'd check here to see what others thought since I wanted to ask about the crown as well.
Have gotten a couple of estimates on repairing the chimney, and had similar conclusions; repoint some joints, seal the crown with crown seal, waterproofing the brick, and reseal the flashing. One to to reseal with silicone, the other Flash Seal.
Also have a patio that needs to be lifted and sealed, and while getting an estimate for that from a different company, the estimator, who started his career in concrete/masonry, suggested having a stainless chase cover put over the crown instead of rebuild (I know from reading some posts that there are differing opinions on this, but for my budget probably the best longevity option). Really need to have both projects done, but not enough money to pay for both as estimated. Being an avid DIYer, I always like to do what I can where I think I can do a proper job, and having some construction background from earlier in life, I really enjoy doing things like this as well. At first I was looking at doing the crown seal myself, but after the recommendation on the chase cover think I will go that route and contract out the repointing but do the waterproofing myself. So the questions on the crown are: should I still put crown seal/crown coat or similar on the crown before or just fill the cracks and put the SS cover over it, and does the gauge of the stainless make a big difference? Other than the cracks, the crown is solid. Looking at ordering the cover from Rockford, and possibly having it powder coated if they'll do that to chase covers like they do for caps.
Appreciate any help/thoughts. Thanks.

Nope that liner is junk. Is that pic from the top or the bottom?

From the top. Thanks for the quick reply.
Never mind at first I thought the liner was upside down. But I looked closer and it isn't. But honestly I would seriously think about whether you want guys who thought that was acceptable doing the work.

This is also why I don't like the 2 ply smooth wall liners

So the liner is ok, just shoddy work?
Yes, unfortunately they were the only ones local that said they install Buck stoves. Company has decent reviews, but I think the crew was new.

No the liner is destroyed.
