How to Install a Stain Glass Window

You still remember the day you found them stashed in the corner of that quaint little antique shop. Layered with dust and all but forgotten, those two stained glass windowpanes were, and still are, captivating. Two houses and many years later you are elated to find those stained glass panes fit perfectly in the window frames next to the front door. Grab your toolkit exciting with knowing in a few hours time your treasured stained glass is beautifully displayed.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Helper
• Utility knife
• Putty knife
• Caulk
• Painter’s tape
• 6 x 2-inch cardboard strips
• Toilet paper

1. Take out the old glass. Remove the beading from around the window on the outside and cut away the putty. With your helper holding the glass in place outside, go inside and free the old window glass. Work your knife between the pane and window frame around the entire circumference of the window; when the glass is completely separated from the putty it slides out easily. Scrape off any remaining putty.

2. Put a thin bead of caulk around the window frame and gently press your stained glass pane into place. Caulk around the frame; you want to ensure the pane is secure and there is no light visible between the glass and the window frame. Use too little caulk and your install will look unfinished; use too much and have a huge mess. Steadiness is key.

3. Fold a cardboard strip so it forms a spring. Stretch painter’s tape across the span of the window and place your string between it and the stained glass to stabilize the install while the caulk dries.

4. Replace the outside beading. Allow to cure for 24 hours. Remove the cardboard spring and clean up any remaining caulk marks on the pane. Enjoy your new stained glass windows.

Tips & Warnings

• Caulk is available clear or in a variety of décor matching colors.
• Use painter’s tape to hold your stained glass in place while you caulk.
• Use toilet paper squares to wipe caulk spills and smudges. Wipe once and discard; this will prevent creating new smears.
• Attempting to remove the old glass alone can lead to breakage and injury.
• Put safety first. Always wear safety glasses and gloves when working with glass and sharp tools.
