Glazing Repair - How to Repair a Cracked Window
Glazing can make a huge impact on the energy efficiency of your home. This is particularly true for older double-glazed windows.
While it is possible to replace the glazing points while the window is still in place, it is much simpler and quicker if the glass and frame are removed. It is a good idea to replace the seals made of rubber.
Broken Glass
Glass that is cracked isn't just ugly but it also allows valuable heat and sunlight escape from your home. It is possible to repair a broken pane of glass without having to replace the entire window.
Begin by putting on protective gloves and safety goggles. You can also employ duct tape or a painter's tap to create an "X" on the glass that you intend to remove. This will stop any broken glass from falling on you as you work.
Cover a small crack on your window with tape to keep insects, water and wind from getting. One strip of tape is sufficient for cracks with a superficial appearance however if you're concerned about the weather getting worse before you can replace your window, consider using an extra-strong plastic cover such as a tarp or a trash bag, to keep the glass in place until you get a permanent fix.

This high-tech adhesive is formulated to adhere to glass and dries crystal clear for the perfect finish. Apply it to the crack and let it dry completely before applying a new layer.
Stress cracks are another common issue that can occur to your glass window. Stress cracks are usually caused by large temperature changes and can spread rapidly across the entire window if not fixed. To prevent stress cracks create a small arc with glass cutters close to the crack. This stops the crack from spreading, and may slow it down by a day or so.
If you're replacing a damaged window make sure you measure the frame to fit the new pane. It should be slightly smaller than the opening to allow for expansion and contraction and to cover any imperfections in the glass or frame. After you've cut your glass to the proper size, apply glaziers' compound around the edges of both the frame and the glass. Once the compound is dry paint it over to match the rest of the frame.

It is more common in winter, when the temperature is lower. This makes it easier for condensation to form. The most likely cause is a defect in the spacer that is placed between the window and the frame. The spacer is made up of desiccant which is very absorbent and absorbs any moisture that is present.
This can lead to water leaking through the gap once the desiccant has been saturated. This can cause water and condensation to build in the gap which is difficult to get rid of.
The good news is that the majority of reputable window companies will offer warranties on their products. They will replace the window unit and glass when it's damaged by condensation. Report any problems as soon as you can to your window installer to ensure that the condensation is repaired as soon as possible to prevent further damage.

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