Our six-unit coop apartment building (brick and mortar) is 82 years old.
Recently some of the inside walls have begun to show water damage, which
indicates moisture coming in from the outside.

Someone told me this indicates we might need to have the building
"repointed." I've never been clear on what this means and what it
involves,
but I would guess that it's expensive.

I have also been told that silicone paint might be a less expensive
alternative to repointing.

Any guidance or experience appreciated.r

Go to the BIA (Brick Industry Association) web site.
The Tech Notes section is very helpful.

I would suggest you look for a forensic architect or engineer.
They could go over the building and give a clear statement of existing
conditions and possible fixes.
If needed, they could rank work in order of importance and time frame.
These services are not cheap, but if done by a competent firm can be
very well worth the cost.
