Fixing a Window on a French Door

Before you try fixing a window on a French door, you need to first remove the broken or shattered window. Using your safety glasses, cover the broken pane with cloth or a towel and tap out the loose shards. Remove any extra pieces that remain in the putty of the window pane. When you’ve removed the broken or cracked glass, take a measurement of the pane. Once you’ve removed the glass, you need to cut the paints seams along the outside of the trim and at joints using a utility knife. In some French doors, there are nails holding the trim in place, pry the trim up as much as you can until you get enough room to use a hacksaw to cut the nails holding in the trim. Pop the trim out of the frame and label each piece.

How to Fix a Window on a French Door

Once you’ve taken the trim out, take your window measurements and transfer the dimensions onto the glass and place it on the particleboard. Wearing your gloves and safety glasses, dab a small amount of oil on the glass cutter. Score the first line with the glass cutter using a ruler or straightedge. Put the glass on the edge of the particleboard and gently snap the glass. Repeat this process for all the cuts. When you’ve cut the correct piece of glass for your pane, put a small amount of latex caulk into the setting to keep the glass inside the window pane. Replace your trim and be careful not to hit the glass with the hammer. When the trim is completely replaced, run a bead of caulk along the outside of the trim. Putty any visible nail holes and paint.
