How To Replacement Glass On Single Pane Wooden Windows

Replacing your window panes can be a very complicated project. The cost and difficulty largely depends on the material of your sashes. For instance, vinyl sashes have glass panes that are fused with the vinyl, so replacing them is very difficult. It is usually easier to just change the entire fixture since vinyl is so affordable. But, if you have wooden windows, it is definitely possible to replace just the panes. This article explains the process of changing single glass panes on wooden windows.

How The Panes Are Changed

Wooden sashes can get warped, especially if they get water damage. This warping is a major concern if you want to change your panes. Most window manufacturers sell replacement parts for old windows. Often, when you remove a warped section of the sash, it will be hard to reattach, so it is easier to use a replacement piece. The one advantage is that warped and otherwise rotted sections are easier to remove. Otherwise, separating the sash so the pane can be removed can be a little tricky.

First, you need to cut away any caulk or rubber weatherstripping that holds the pane in place. Then, using a hammer and chisels, you need to pry away one stile (on the side) and one jamb (on the bottom). Once 2 of the 4 sections are removed, you can probably remove the glass. In the worst cases scenario you will need to remove the other stile to get the pane loose. 

Installing the New Panes

Replacing the panes is obviously simpler if you order glass that is the exact same size, including thickness. You might want to consider installing tempered glass because it is more efficient and shatterproof. To reattach the removed (or new) sash sections, you need a nail gun and air compressor kit. It is helpful if you have a helper who can hold the glass pane in place while you attach the jamb. Once the jamb is installed, your glass will be secure and you can easily attach the stile. You also need to use silicone caulk on both sides of the pane to secure it and make it air tight. You will also probably need to paint your entire window sash in the end.

This work can be delicate and time consuming, but it is well worth it if your window panes are currently loose and leaking air. Contact a window company, like Distinctive Siding & Window, if you need more help.
