How To Replace a Broken Window Pane

You hear a crash and run to the living room to find a baseball rolling around your floor! Accidents can happen, but you don’t always need to call in a professional for repairs!

Replacing single paned windows is a pretty simple job that almost anyone can do in a few hours! If you have double or even triple paned windows, then you may not have a choice but to call someone that’s got a little more experience.

Installing a new glass pane is a lot easier if you can remove the window and lay it on a table or even the floor. Depending on the type of windows you have, there will either be some moulding strips or just glazing compound that goes around the glass and frame.

If your windows have strips be careful when removing them, you’ll need to re-use them for the new glass. After you’ve got them removed, scrape off all of the old window putty or glazing from the window bed.

If the material has became really hard, you can use a heat gun to lightly warm it and loosen it up. If you don’t have a heat gun, you can use a torch or some other type of heat, but be very careful not to scorch your window frame.

Once you’ve gotten all of the old glazing off of the frame, you will be able to see the glazing points. These are tiny metal chips, usually triangular shaped that are pushed into the wood up against the glass to hold it in place.

Remove all of the glazing points and carefully remove all of the broken pieces of glass. After you’ve taken the glass out throughly clean the channel where the glass sits and remove any remaining compound.

To make sure the area is completely clean, use a small piece of sand paper to sand the area all the way down to the bare wood. Measure the exact opening size and then subtract 1/8 of an inch from each side to get the right size glass that’s required.

You will need to apply a primer or coat of sealer to the sanded area and let it dry. When it’s dry, apply a thin coat of glazing compound all around the area where the window sets with a putty knife. About 1/16 of an inch is all that’s needed.

Insert the glass and gently press it into place, all of the edges  should come in contact with the compound. The glazing compound will seal the glass to prevent any water from leaking down  between the glass and frame when it rains.

The glazing points can easily be pushed back into the frame with the putty knife to hold the glass in place. Get them as close to the glass as you can to hold it securely against the window frame.

You should put at least two glazing points on each of the four sides of the glass. For large panes, it’s recommended to use one glazing point for every ten inches on each of the four sides of the glass.

If you’re window had strips that went around the glass, you can  replace them now. But, if there wasn’t any strips, use a small putty knife or your finger to apply more glazing compound or window putty around the entire glass.

The compound should be applied in a V-shape around the glass to make a nice smooth slope from the glass to the frame. You don’t have to wait for the compound to dry completely to paint it. As soon the surface of the compound has dried you can go ahead and paint over it.
