Installing Single Pane Windows: The Process

1. Removing the Window

Tape a large "X" across both faces of the single pane window. Cover the glass with a towel and hit it with a hammer to break it. With the help of work gloves, carefully remove the glass shards and dispose. Use a chisel on the windowpane to remove the glazing compound. Then apply a fast drying primer on the exposed wood. While the primer is drying, take the measurement of your single pane window and a secure a piece of replacement glass that is 1/8 inch smaller than the original window dimensions.

2. Installing the Replacement Glass

Apply a liberal bead of caulk around the outer part of the frame to prep it for the single pane window replacement. Linseed oil will accomplish the same job. Place the replacement glass into the frame and press it down firmly into the caulk.

3. Finishing the Glazing and Sealing

Now is the time to place new glazier points to hold the replacement glass into place. Run a knife over the rough edges to smooth down the surface. Clean the glass with turpentine or mineral spirits and a soft rag. Wait a week before painting the seam between the single pane window frame and the glass. This will give the setting the time it needs to remain secure. To ensure an even better positioning of the window, use a metal frame.
