with you that trying to find area's of air infiltration is a good place to start. Also if
this years winter is much colder than last year that could be a factor.

This is true. If he has a drywall return he’ll have to cut into the drywall to access the roughy opening, but I’m assuming the era of his house and where he is he’ll have wood trim instead. If so, there will be some gap between the drywall and rough opening. Even if not, he can cut the drywall back a bit and it will be covered by trim when he puts it back on, so drywallrepairs wouldn’t be much of an issue. The idea is that he can stick the nozzle of a closed cell foam dispenser into the openings in that joint and fill the void with foam. His builder probably used fiberglass all those years ago and it’s probably not doing much anymore. If he does have a drywall return, it’s not a big job to punch a hole in it and stick a borescope into the rough opening and see what’s there. Then he’d just use a couple of holes like that around each window to apply the foam. Drywall repair to access the wall cavity really isn’t a big deal when reworking a window installation. It’s a lot less disruptive than replacing them.
