The wife also makes some points for replacement over renovation: modern windows are hinged for easy cleaning, have modern latching hardware (she wants two latches, not just one), and come with two lifting handles (ours has just one little handle). I'm pretty sure I can swap out latch and handle hardware, but I don't think I can make 80 year old windows swing for easy cleaning.

That said, I'd feel like I was giving up if I just went out and bought new windows. I'd feel a lot better at least attempting one or two before going down that route.


Routing out bigger rabbets is a great idea. I'm 90% sure that my existing rabbets aren't big enough to take much thicker glass. I've got a box of glaziers points (which are really just tiny steel nails), and tubes of white silicon sealant are easy to come by. I'll have to pry the trim off to get to the counterweight slots, but (fingers crossed) it's quite likely that the counterweights are still there.

Any recommendations on sash sealing? How do you keep the air from getting in around the sash, or from between the sashes?

Thanks,
Dan
