Replacing French Door Glass
Replacing a broken pane of glass on a French door is a relatively simple DIY project. Cleaning the glass, removing trim and molding and then putting in a new pane of glass is all that's needed.
French doors are made of multiple glass panes, separated by muntin bars for functional purposes, also known as mullions. They are available in a variety configurations and can also include triple-pane glass in order to boost energy efficiency, cut down on sound and reduce the glare.
How do you replace a damaged pane of glass
Wear rubber gloves and safety glasses before you begin to replace the glass. This will protect you from any broken glass shards that may fall during the process. Work in an open area such as garages and keep children away. It is best to remove the window frame from the sill for better accessibility and maneuverability however, you can replace a pane without taking the entire window out of the frame.
Begin by scraping away any old glazing compound or caulking around the edges of the sash using a putty knife. Be careful not to damage the wood molding that holds the window in place since you'll need it in the future to support the new pane.
If you are working with a steel casement window it could be anchored by the metal glazing points. These points, as well as the old putty will have to be removed prior to you can remove the pane from the frame. A paint scraper or chisel should work however, if you find that the putty's too hard to remove, gradually soften it with a heating gun. The heat gun should be held about an inch from the glass and move it back and forth to spread the heat. Double-up the aluminum foil and then place it on the glass adjacent to it. This will prevent them from breaking due to the heat.
Once the old glass has been removed, wipe down the inside of the window sash with a damp cloth to clean off any dust or dirt. Then, you can put in the new glass.
Take measurements of the width and height to determine the dimensions of the glass. Note these measurements and subtract 1/8 inch from all sides to get a new glass that will fit easily into the door frame. Many hardware stores can cut a piece for you if they have the measurements.
Warm up a few tablespoons of putty and then roll it into a 3/4-inch wide rope. Place the putty on one edge of the rabbet, and rest the blade of your putty knife at a 45-degree angle with the frame's rabbet. To cut a piece of the pane, move the knife in a smooth and straight line along the glass's edge. Repeat the process for the other edges of the pane.

Take the broken Pane
A broken pane in a French-style door not only an eyesore however, it could also be a safety risk. Replacing glass in a French door is done in a few easy steps, and is generally less expensive than replacing the entire door panel. Most homeowners can do this task themselves, though professional assistance is available in the event that the project requires specialized skills or tools.
Begin by removing the broken pane of glass and clean any broken or cracked pieces from the frame. It is important to wear gloves and goggles to avoid getting shards of glass in your eyes or face. Then, clean the glass opening to eliminate any caulking or putty you used to hold the previous pane in place.
Next, you need to remove any trim or molding that held the glass in place. It can be difficult to pull the molding off. Wearing protective equipment and having someone help you in the process of prying is a good idea. Label the pieces that you're removing so that they can be returned to their original positions.
The installation of the new glass is easy once the molding has been removed. Go to a glass store and take measurements of the opening of the glass. You should purchase the safety glass for your French door, as it will not shatter easily if it breaks again.
When you're ready to install the new piece of glass make sure that it's aligned properly in the opening. Then, you can apply a thin dot of clear silicone caulk over the glass's edge.
You can change the molding after the caulk dries. If the original nails didn't penetrate the molding, you can put in new wire nails to fill the holes left by the old nails. The holes should be predrilled to stop the nails from splitting through the molding. A well-stocked hardware store carries tiny bits that can be used to drill holes.
Cut a New Pane of Glass
Before purchasing a new piece of glass, ensure that the frame's spacing and the edges of the window are equal. If you find any gaps, you might require adjusting the spring clips or the metal triangles that hold the glass in place. You also need to make sure that the new pane is adequate size for your opening; if it's too large, you may experience leakage or other issues when it is installed.
The first step is to make an area for work. Scrape the old compound off the frame's sides using a putty knife to reveal the bare wood. If the rabbets are too rough to smooth with a putty knife, lightly sand them and brush on an exterior primer. This will stop the new glazing from absorbing moisture from the wood, shortening its lifespan.
Once the frame is clean and prepped, warm a handful of putty by kneading it until soft and malleable. Apply a thin layer with the putty blade on the inside corner rabbets to create a narrow bed that the glass can rest. Repeat the process for the other exposed edges.
After the putty is dry and the putty is removed, you can remove any remaining glazing points that are stuck in the grooves of the sash. Wear safety glasses prior to attempting to remove the points to protect yourself from shards of glass. Heating guns with low settings can be used to gently heat the metal and loosen it up so that it is possible to remove it with pliers.
Place the glass on the table to test the fit. Adjust the glass as necessary before securing it using spring clips or metal triangulars. Make sure that the gap between the frame and glass is uniform on all sides. Check the movement of the window sash and make sure that the new glass does not hinder the closing or opening. Consult a restoration specialist in case you have any issues during the installation. They can assist you to repair and maintain your home's historic features.
Install the Pane of Glass
Test-fit the new glass pane to ensure that it fits snugly before putting it up. Measure the width and height of the window opening, in relation to the edges outside of the L-channels. Subtract 1/8 of an inch from each measurement in order to determine the glass size you need. A little undersizing of the pane will allow it to be installed more easily and provide room for seasonal expansion and contraction of the wood frame. You can take your measurements to the hardware store or home centre and they will cut a piece of glass for you. You can also cut the glass yourself, when you have a huge sheet available.
Once the old pane of glass is removed, remove the window sash grooves and remove any metal glazing points which held the previous pane in place. A paint scraper that is a pull type or a chisel is ideal for this task. If the grooves contain a lot of hardened putty in them, you can gradually soften it by using a heating gun. Cover surrounding windows and moldings with aluminum foil to protect them from heat.
It is also possible to use an exterior primer to keep the putty from absorbing its natural oils. It is also recommended to clean the sash to remove any dirt and dust from the grooves.
Knead a tiny amount of putty until it's soft and warm Then press it into the rabbets in which the glass will go. At this stage, neatness is not important. Place the new pane in the rabbets, then move it around and apply even pressure with your fingers to ensure it's seated properly.
If there are any holes in the frame of wood around the glass, fill them with silicone caulk before installing the new glass pane. If the frame is equipped with other fastening mechanisms, like L-channels, you can use a hammer to pry them out of the sash grooves. Get rid of any shards that might have become loose when removing the frame. Then, apply a layer of clear silicone caulk on the bottom of the frame where it meets the floor to keep pests and water out of the home.
