I've got the original georgian, wooden window panes in the house which is nearly 100 years old. The biggest window has 50 panes.
The problem is trhat the old putty is coming away leaving troughs between wood and glass and I don't know how to fill them. I tried putty but the troughs aren't deep enough and ther putty comes away. I did a window last spring but the window gets a lot of condensation and by the end of last year it became clear that I would have to redo it; I suppose water/condensation is getting under the paint and is cracking it
I wonder what is best to get a watertight seal? I have put some epoxy 2 part putty ( milliput) in the deepest troughs , but I'm not sure this will work longer term as it is not flexible. I have also tried some decorators caulk over some of the shallower troughs. I am going to repaint in the spring but don't want to do all the work only to find that I haven't used suitable filler.
