My parents recently purchased a house, built in 1950, that features full-dimension granite veneer.

The basement is concrete block up to the height of the rough sawn joists, where it appears to transition to brick on the interior. I'm not sure what the wall structure looks like above the first floor.

A piece of granite six inches thick was removed in the above-grade portion of the basement wall to permit the installation of a lineset. I'm concerned the original mortar might have been lime mortar. What is the appropriate masonry product to seal around the sleeve for the lineset? I'll send the mortar in for analysis before it needs to be repointed.

what is a 'lineset' ???

I suppose the preffered spelling is "line set," but I've seen it written both ways. A line set is a pair of copper refrigerant lines (suction and liquid) running between an AC condenser and its evaporator.

What's the nearest big city the house is in?

You'd probably need to talk to the old timers in the area to find out what they were using back in 1950. Or send it in for testing.

The house is in northern New Jersey. Unfortunately, a mason who was 25 in 1950 is now 95 years old! We don't have too many of those treasures left.

If you want to be safe, use a lime mortar. The repair sounds pretty small.

I'm hardly a mortar expert though. But a 6" thick piece of granite veneer sounds pretty bullet proof. I can't imagine that getting messed up.
