Remove Old Glazing

Soften old, hardened putty (glazing compound) with a heat gun set to medium and fitted with a nozzle shield. Scrape the putty away with a putty knife. This exposes the metal glazier’s points; pry them out of the wood. Remove the glass, and label it so you know which opening to put it back into.

Rebuild Rotted Wood

To rebuild the cleaned-out joints, first brush on the epoxy primer and let it set for about 20 minutes. Then, using a plastic scraper, mix the two parts of the epoxy filler into a goop the consistency of Vaseline. Force it into the joint, and spread the mix over the sides to restore the joint’s original shape. Wait overnight, then trim the excess with a utility knife.

Tip: Clamp pieces of Plexiglas over the wet epoxy. When it hardens, take the plastic off. You’ll have a smooth surface that doesn’t need much sanding.

Sanding/Scraping and Priming

Sand/Scrape the entire sash with 100-grit sandpaper or scraper. Clean the sash then prime with oil based primer
Leave the sides as bare wood because they need to slide
Leave the top of the top sash bare wood
Leave the bottom of the bottom sash bare wood



Place putty on the ribbets (inside part of sash the glass lays on)
Add the glass and rub it so it adheres better to the putty. Do not push on it or it can break
Add glazing points
Add last layer of putty on top of the glass

* Wait 2-3 weeks before painting the putty *

Painting and Hardware

Fill hardware holes
Use exterior paint if possible for the outside facing sides
Add hardware. Screw nails in at an angle for easy access
Extend paint over putty onto the glass about 1/16 to seal water out

Spring Bronze Weatherstripping

Old Town Home has a great write-up on how to do weatherstripping:

“When you measure for your first cut, measure from the top of the window jamb down to the point where the bottom of the upper sash sits when fully closed. Add 2.5 inches to this measurement, as you want the weather stripping to extend below your sash a bit.”

I provide resources for contractors, websites, and videos I used to do my projects that will have additional information . I hope you find them handy as well!
