Over time, window and door glass may need to be replaced due to damage, cracks, fogging between panes, or simply to upgrade to a more energy-efficient option. Replacing glass is a careful process, but with the right tools and method, it can be done smoothly. At KDSBuilding, our windows and doors are designed with durable frames that make glass replacement practical while maintaining the strength and beauty of the original product.

The first step is preparing the area. Before removing the old glass, it is important to wear safety gloves and protective eyewear, as broken glass can be dangerous. Clear the space around the window or door to make sure you have enough working room. If the glass is cracked but still in place, tape across the surface can help prevent loose pieces from falling during removal.

Next, the sash or panel is removed from the frame, if possible. For windows such as casement, sliding, or tilt-and-turn types, the sash can usually be lifted or unscrewed and taken out for easier handling. For doors, the panel often remains in place, but the glass area can still be worked on directly. Once accessible, the glazing beads, stops, or trim that hold the glass in place are carefully pried off using a putty knife or small pry tool. These parts should be removed slowly to avoid breaking them, since they will be reused later.

With the stops removed, the old glass can be taken out. If the glass is a single pane, it will lift out once loosened. If it is a double-glazed insulated unit (IGU), it may be lightly sealed to the frame with glazing tape or silicone, which needs to be cut through carefully. At this stage, all old sealant, tape, and debris should be cleaned from the frame to prepare for the new glass. A smooth, clean surface ensures a secure and airtight installation.

The new glass panel is then placed into the frame. For KDSBuilding products, customers can choose energy-efficient, NFRC-certified double or triple glazing, laminated safety glass, or tempered glass for added strength. The new glass should match the original size and thickness exactly to fit correctly. Once set into position, glazing tape or sealant is applied around the edge to hold it firmly in place and create a weatherproof seal.

After the glass is secure, the glazing beads or stops are reinstalled. These are pressed or snapped back into position around the glass edge, locking it tightly against the frame. Care is taken to ensure all sides fit snugly without gaps. For windows where the sash was removed, the sash is reinstalled into the main frame, making sure it operates smoothly.

Finally, the glass is cleaned and inspected. Any remaining sealant or fingerprints are wiped away, leaving a clear and polished finish. The window or door is tested to confirm that it opens, closes, and locks properly.

By following these steps, homeowners can replace broken or outdated glass while keeping their existing frames intact. With KDSBuilding’s high-quality glazing options, replacement not only restores safety and appearance but also improves insulation, reduces noise, and enhances overall comfort.
