Some time ago we saw a This Old House segment on replacing jam liners in old wood double hung windows. We don't know the brand of windows as our house is very old. We would like to retrofit the second story windows to tilt in. Does anyone know of a supplier for these or the program it was on?
We can't afford to replace the windows themselves and are too old to be climbing a ladder twice a year! We and a friend have tools and carpentry skills.
