Glazing Repair - How to Repair a Cracked Window Glazing can make a huge difference in the energy efficiency of your home. This is especially true in older double-glazed windows. While it is possible to replace glazing points while the window is still in position, it is faster and simpler when the frame and glass are removed.

Fortunately, it's often possible to repair a broken window without the need for full replacement. Begin by putting on your protective gloves and safety goggles. You should also put an X-shaped piece of tape an X shape on the glass you intend to remove (duct or painter's tape works well). This will stop any broken glass from falling on you as you work. If you have a small scratch in your window glass you can cover it with tape to block the elements like wind, water and insects. One strip of tape is sufficient for cracks with a superficial appearance but if you're worried about the weather getting worse before you can replace your window, consider using a heavier-duty plastic cover, like a tarp, or a garbage bag, to hold the glass in place until you get a permanent fix. For cracks that aren't as shallow try using a tough adhesive that is specifically designed for windows, like Loctite Super Glue Glass.

Stress cracks are another common issue that can occur to your glass window. They are usually caused by large changes in temperature, and can quickly spread across the entire glass window if not treated. To stop stress cracks from occurring create an arc of a tiny size with glass cutters near the crack. This will prevent the crack from expanding and reducing the severity for some days. If you're replacing an old window make sure you measure the frame to fit the new pane.

This is more frequent in winter, when the temperature is lower and it's more easy for condensation to develop. The primary reason for this is a defect in the spacer placed between the window and the frame. The spacer is often filled with desiccant which is highly absorbent and can absorb excess moisture. This can lead to moisture seeping through the gap once the desiccant has been saturated. This can cause condensation and water to build within the gap, which is difficult to remove. The good news is that the majority of reputable window companies will offer a warranty on their products and should replace the window unit and glass if it has been damaged by condensation.
