We've been dealing with colder air coming through a couple windows during winter and i already tried resealing around the frames a few months ago which helped a little but certain rooms still feel noticeably colder especially at night.

The house is older and i honestly can't tell if the issue is the seals glass or the installation itself at this point. There's also occasional condensation showing up on one of the windows when temperatures drop a lot outside.

I'm trying to figure out whether this sounds repairable or if replacement usually becomes the better option once it gets to this stage
