How to Remove and Install Glass Replacement

The cost of glass replacement can add up quickly, especially for larger windows. Whether you have broken windows or want to give your home an upgrade, it is important to know when it makes sense to hire a window glass professional for a full replacement or to simply replace the glass. The process of removing and installing new windows is similar for both options, however, the level of difficulty varies depending on the type of window frame you have. For vinyl windows, the process is much easier than working with wood frames. Before you start the installation, it is important to take the time to ensure safety and accuracy. Make sure you wear leather work gloves and eye protection. Apply a crisscross pattern of masking tape over the entire surface of the existing window to avoid shattering into smaller pieces. It is also a good idea to cover the broken glass with sheets of newspaper, as it will bind any small pieces that do break.

To remove the old window, you will need to first remove the sash, which is the moveable part of the window. To do this, lift the sash and pull it from the bottom until it is completely removed from the window opening. After this is done, you should be able to remove the broken pane with the help of a pry bar or screwdriver. Make sure you clean the window frame of any remaining glass, adhesive, or glazing compound before taking any measurements for the replacement. Ensure that you are accurate when taking these measurements, and subtract 1/8 inch from each side to allow for expansion and contraction. Once you have these dimensions recorded, you can take them to a local hardware store and get the new glass cut.

If you are using a wood frame, you will need to prepare the rabbets for re-glazing. Scrape any paint or glazing compound from the inside of the sash with a utility knife, and use a wire brush to loosen any bits of debris that are stuck in the smaller crevices of the frame. Once the frame is cleaned, lightly sand the l-shaped grooves down to bare wood, and coat it with a wood sealer.

Once the frame is dry, it is time to install the new pane. Using the same method of measurement and sizing, you will apply the putty around the edges of the new glass, making sure that it is pressed firmly into the rabbets. You will need to wait about a week for the putty to fully harden.

Glass-only replacement is a great option for older single-pane windows or homes that are in need of an upgrade. However, it is important to remember that this is not a long term solution and is only an option for those who are not experiencing other problems with their windows like drafts or rot. It is also important to check the window manufacturer’s warranty, as they may offer a lifetime warranty that includes glass-only replacement.
