Glazing Repair - How to Repair a Cracked Window

Glazing can make a significant difference to the energy efficiency of your home. This is particularly true for older double-glazed windows.

Broken Glass

Cracked windows are not only unattractive, but also allow valuable heat and sunshine to escape your home. It is possible to repair the glass that is cracked without having to replace the entire window.

Wear safety glasses and gloves. You can also use duct tape or painter's tape to make an "X" on the glass that you intend to remove. This will stop any broken glass from falling onto your work surface as you work.

Cover a small crack on your window glass with tape to keep bugs, water and wind from getting. One strip of tape should be enough to cover any cracks that are superficial but if you're worried about the weather getting worse before you can replace your window, use an extra-strong plastic cover like a tarp or trash bag, to hold the glass in place until you can get a permanent fix.

For cracks that aren't as deep Try using a strong adhesive specifically designed for windows, like Loctite Super Glue Glass.

Stress cracks are another frequent problem that can happen to your glass window. They're typically caused by dramatic changes in temperature, and can spread quickly across the entire glass window if they aren't fixed. To prevent stress cracks create a small arc with glass cutters near the crack. This will stop the crack from spreading, and can slow it down by a few days.

It is more prevalent in winter, when the temperature is lower. This makes it easier for condensation to form. This is caused by a defect in the spacer that is used between the frame and the window. The spacer is often filled with desiccant that is extremely absorbent and will soak up excess moisture.

The issue with this is that once the desiccant gets saturated, it will start to break down, and eventually water can begin to leak through the gap between the glass units. This can cause condensation and water to build in the gap which is difficult to remove.

This will allow the new putty to stick to the frame securely.

Once the frame is cleaned and the rabbet is in place, it's time to plan the replacement of the broken pane. Order a piece of double strength glass that is one inch smaller in both directions. You'll also need glass points, which are steel triangles which keep the glass in place.

With the window sash removed and the pry-bar flat, use it to gently pry the sash away from the moulding of wood. You may have scrape off old glazing putty with a knife or chisel. Then you can use the heat gun to warm any putty that isn't able to come off. This will make it easier to peel off.
