Replacing French Door Glass
Replacing a broken pane of glass on a French door is a relatively simple DIY project. It involves cleaning the pane of glass trimming or molding and installing an entirely new window pane.
French doors feature multiple glass panes that are separated by muntin bars for functional purposes, also known as mullions. They are available in a variety of configurations and may include triple-pane glass to improve energy efficiency, cut down on sound and control the glare.
How to Replace a Broken Pane of Glass
Before you start the replacement process, wear rubber gloves and safety glasses to protect yourself from any shards of broken glass that might fall off during the replacement process. Work in an open space, such as a garage, and keep kids away. It's best to remove the window frame from the sill for better access and maneuverability, but you can also replace a window without taking the entire window out of the frame.
Start by scraping off any old glazing compound or caulking around the edge of the sash with a putty knife. Be careful not to scratch the wood molding that holds the window in place, since you'll need it in the future to hold the new pane.
If you're working with a casement window made of steel, it may be secured by metal glazing points. It is necessary to remove these, as well as the old putty before you can get the glass out of the frame. Paint scraper or chisel will work. If the putty is too hard to remove, you can employ a heat gun in order to soften it. Hold the heat gun about 1 inch away from the glass and move it around to spread the heat. Double-up the aluminum foil and then place it on the adjacent panes. This will prevent them from breaking due to the heat.
After removing the old glass, take a damp cloth to wipe the inside of the window sash to remove any dirt or dust. Then you can install the new glass.
To cut a piece of glass to size first, determine the width and the height of the opening. Record 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 will cut a piece glass for you, if you give them the measurement.
Warm up a handful of putty and then roll it into a 3/4-inch wide rope. Position the putty on the edge of the rabbet. Place the blade of your putty knife at a 45 degree angle against the frame rabbet. Pull the knife across the edge of the glass in a smooth, straight line to cut a section of the pane. Repeat the procedure with the other edges of the pane. Then, scrape off the excess putty.
Remove the Broken Pane
A glass pane that has been broken in a French door isn't just a source of irritation for the eye it's a risk to your safety. Replacing a pane of glass in a French door is done in a few easy steps and is typically less costly than replacing the entire door panel. The majority of homeowners are able to complete the task on their own, but professional assistance is available for those who require special tools or skills.
Start by taking out any cracked or broken fragments of the frame. It is important to wear gloves and goggles to avoid getting shards glass in your face or eyes. Then, clean out the glass opening to remove any caulking or putty that was used to hold the previous pane in place.
The next step is to eliminate any trim or molding holding the glass in place. This can be a challenge because it may require some effort to pry the molding off. Wearing protective equipment and having a person help you in prying is an excellent idea. It's also a good idea to label the pieces you're pulling off, so you know when to put them back when you're ready.
Once the molding is removed, you can begin installing the new glass pane. Measure the dimensions of the opening for the glass pane, and then go to a glass shop to purchase a piece glass that is new for your French door. You should get security glass for your French door, since it will not break easily if they break again.
Once you're ready to set up the glass piece make sure that it's aligned properly in the opening. Then, you can apply a thin bead of clear silicone caulk over the edge of the glass.
You can replace the molding once the caulk has dried. If the original nails did not penetrate the molding, you can hammer new wire nails into the holes left by the old nails. By drilling the holes prior to drilling, you can stop the nails from splitting through the molding. You can drill the holes using tiny bits from a hardware store that is well-stocked.

Double-check the spacing around the frame of the window as well as the edges before you order a replacement pane. It is possible to adjust spring clips or triangulars to hold it in place if there are gaps. Also, you should ensure that the new pane is the right size for the opening. If it's too large it could cause leakage and other problems.
The first step is to create an area for work. Scrape the old compound off the frame's sides with a putty blade to reveal the bare wood. If the rabbets on the frame are too rough to smooth using a putty knife, lightly sand the edges and apply an exterior primer. This will stop the new glaze from absorbing moisture from wood, which will reduce its life span.
Once the frame has been cleaned and prepared, you can knead a handfull of putty until it is soft and malleable. Apply a thin layer with the putty blade on the inside of the corner rabbets in order to create a bed against which the glass can rest. Repeat the process for the other edges that are exposed on the rabbets.
Remove any remaining metal points that remain in the grooves of the sash when the putty has dried. Before attempting to remove them, wear a pair of safety goggles to shield yourself from glass shards. A heat gun set to an low setting will help you warm and loosen the metal, to allow you to bend it out of the frame with pliers.
Slide the glass into place to check the fit. Make any adjustments needed before securing it in place with spring clips or metal triangles. Make sure that the gap between the frame and the glass is uniform across all sides. Examine the movement of the window sash to make sure that the new glass does not hinder the opening or closing. If you have any issues regarding the installation, consult an expert who specializes in restoration, who can help you restore and maintain your home's historic features.
Install the Pane of Glass
Before you install the new pane of glass You should fit it by testing to ensure that it fits properly. Measure the width and height of the window opening, in relation to the edges of the L-channels. Subtract 1/8 inch from each measurement to find the size of glass you should order. A little undersizing of the pane will make it easier to install and provide room for seasonal expansion and contraction of the wood frame. Take your measurements to an hardware store or home center, and let them cut a piece glass for you. You can cut the glass yourself if you have a large piece available.
After the old pane glass has been removed, you must clean out the window sash grooves, and take off any glazing points made of metal that held the old pane in place. A paint scraper that is a pull type or a chisel can be used to accomplish this task. If the grooves are filled of hardened putty, gradually soften it using a heat gun. Cover the moldings and windows with aluminum foil to keep them safe from heat.
It is also possible to use an exterior primer to prevent the putty from absorbing the natural oils. You should also wipe down the sash in order to remove dust and dirt from the grooves.
Knead a tiny amount of putty until it is soft and warm, then press it into the rabbets where the glass will go. Neatness isn't important at this point. Press the new pane in the rabbets and then wiggle it by using your fingers.
If there are holes in the frame of wood around the glass, fill the holes with silicone caulk prior to installing the new glass. If the frame has other mechanisms for fastening like L-channels, you can use a hammer to pry them out from the sash grooves. Check the frame for glass fragments that might have broken during removal, and remove them before proceeding. Then, apply a layer of clear silicone caulk on the bottom of the frame where it connects to the floor to keep water and pests out of your home.
