Does the chimney need fixing

[Stina Hagman]

I'm looking for some advice. When I bought the house about 17 years ago, the inspector advised me that it was probably time to regrout the chimney. I had planned to do it this year (... better late than never). But when I feel the grout, it's stable and shows no signs of crumbling. It has been standing since the house was built in 1953 as far as I know. Should anything be done or is it better to leave it alone?

Did you look inside or outside? Post some pictures of it.

I thought I posted pictures in the thread starter, but I'm a bit unfamiliar with the forum.

It wasn't a disaster but it's time to start reviewing the joints.

Milling out and repairing with KC-c mortar? How deep should I mill? The joints currently in place feel quite hard, so I'm thinking it's more cement than usual (?).
