Replacing French Door Glass

Replacing a damaged pane of glass on a French door is a simple DIY project. It involves cleaning the pane of glass and removing molding or trim and then putting in an entirely new window pane.

French doors have multiple glass panes that are separated by muntin bars that are functional also known as Mullions. They come in a broad variety of designs, and can be triple-paned in order to reduce noise and control glare.

How do you replace a damaged glass pane

Wear rubber gloves and safety goggles before you begin to replace the glass. This will shield you from any broken glass shards that may fall during the process. Also work in a garage or another open space, and keep children away from the area. To make it easier to access the area it is recommended to remove the window frame from its sill. However you can still replace one pane of glass without having to remove the entire frame.

With a putty blade use a putty blade to scrape off any caulking or glazing material around the edges of the window sash. Be careful not to damage the wood molding that holds the window in place as you'll need it later to hold the new window.

If you're working with a casement window made of steel it could be held in position by metal glazing points. It is necessary to remove these, as well as the old putty, before you can remove the window out of the frame. A paint scraper or a Chisel can be used, but if you find that the putty's too hard to get out, slowly soften it with a heating gun. Hold the heat gun an inch from the glass, and move it forward and backwards to spread the warmth. Double-up the aluminum foil and then place it on the adjacent panes. This will stop them from breaking due to the heat.

After 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 install the new glass.

Measure the width and height to determine the dimension of the glass. To order a new glass pane that is sized to fit inside the door frame, measure these measurements and subtract an eighth inch from each side. Many hardware stores will cut a piece glass for you if you provide the measurement.

Warm up a handful of putty and roll it into a 3/4-inch thick rope. Set the putty in a position that is against one edge of the exposed rabbet, and rest your putty knife's blade at a 45-degree angle with the frame's rabbet. To cut a piece of the pane, move the knife in a straight and straight line along the glass's edge. Repeat the process with the remaining edges of the glass, and then scrape away the excess putty.

When you're ready to install the new piece of glass make sure that it's aligned properly in the opening. Apply a thin layer of clear silicone caulk to the edges of the glass.

After the caulk has dried it is possible to replace the molding. If the nails that were used originally did not pull through the molding, you can put in new wire nails to fill in the holes left by the old ones. The holes should be predrilled to prevent the nails from splitting through the molding. You can make holes using very thin bits from the hardware store that is well stocked.

How to cut a new Pane Of Glass

Before purchasing a new piece of glass, ensure that the frame's dimensions and the edges of the window are equal. It is possible to adjust spring clips or triangulars to hold it in place if you notice gaps. It is also important to make sure that the new pane is appropriate size for the opening. If it's not large, you may experience leakage or other problems when it is installed.

The first step is preparing a work surface. Scrape the old compound off both sides of the frame using a putty knife to reveal the bare wood. If the rabbets of the frame are too rough to smooth using a putty knife and you want to smooth them out, lightly sand them and apply an exterior primer. This will stop the new glass from absorbing moisture from the wood, and will reduce its life.

Once the frame has been cleaned and prepared, rub some putty until it becomes soft and malleable. Use the putty knife to apply a thin layer of it to the inside corner of the rabbets. This creates a narrow bed for the glass to rest against. Repeat the process for the other edges that are exposed on the rabbets.

Remove any remaining metal pieces from the sash's grooves when the putty has dried. Before you attempt to remove them, put on goggles with safety features to protect yourself from glass fragments. The low setting of heat guns can be used to gently warm the metal, allowing it to loosen so that it is possible to remove it with pliers.

When the frame and glass are ready, test-fit it by sliding it into its place. Adjust the glass as necessary before securing it with spring clips or metal triangulars. Check that informative post between the frame and the glass is consistent on all sides. Test the movement of the window sash, and ensure the new pane will not hinder the closing or opening.

Subtract 1/8 of an inch from each measurement to determine the size glass you require. By slightly undersizing the glass, you will make it easier to install and allow for seasonal expansion and contraction of the wood frame. You can take your measurements to a hardware store or the home centre and they will cut a piece of glass for you. You can cut the glass yourself, in the event that you have a large sheet available.

Once the old pane of glass is removed, remove the window sash grooves, and remove any glazing points made of steel which held the previous pane in place. This can be done with a scraper that is a type of pull, or a Chisel. If the grooves are full of hardened putty, slowly soften it by using a heating gun. Be sure to cover the surrounding windows and molding with aluminum foil to protect them from heat.

You can also use an exterior primer to stop the putty from absorbing its natural oils. It is also recommended to clean the grooves in the sash.

Knead a tiny amount of putty until it's warm and flexible Then press it into the rabbets, where the glass will go. The appearance of the glass isn't crucial at this stage. Put the new pane into the rabbets, then wiggle it around and apply consistent pressure using your fingers to make sure it's properly seated.

If there are any holes in the frame of wood around the glass, fill the holes with silicone caulk prior to installing the new pane of glass. If the frame has other fastening mechanisms, like L channels, use an hammer and pull them from the sash grooves. Remove any shards that may have come loose during the removal of the frame. To prevent pests and water from entering the house Apply a clear silicone caulk on the bottom edge of frame where it meets the floor.
