Internal repointing

I live in an old Victorian mill conversion which was originally built with an ugly black ash mortar. I’ve decided to have the two of the walls repointed internally, using lime mortar. However I’ve read that entire elevations shouldn’t be repointed unless absolutely necessary, especially in old buildings and am now worried that I might have compromised the structural integrity of the building. Have I made a mistake? Any advice would be much appreciated.

Shouldn’t be any issue with repointing wall as long as you’ve used actual lime mortar. Lime mortar will let the brick work breath and move as it should.

Yes there’s no problem in doing the repointing, has long has you have used the correct lime mix and a 3.5 nhl lime.
Hope this helps.
