Glazing Repair - How to Repair a Cracked Window
Glazing can have a significant effect on the energy efficiency of your home. This is especially true in older double-glazed windows.
It is possible to replace the glazing points by putting the window still in place, however it is much simpler and faster if you take off the frame and glass. It is a good idea to replace the rubber seals.
Broken Glass
Glass that is cracked isn't just ugly, it can also let valuable heat and sunlight escape your home. It's possible to fix the glass that is cracked without having to replace the entire window.
Begin by putting on your protective gloves and safety glasses. You can also apply duct tape or painter's tape to make an "X" on the glass you want to remove. This prevents any shattered pieces from falling as you work, which could protect you from serious injury.
Cover a small crack in your window glass using tape to keep bugs, water, and wind out. If the crack is superficial just a single strip of tape will suffice. However, if the weather is likely to get worse before you can replace the window, you may prefer a sturdy plastic cover, such as the trash bag or tarp.
Use a strong adhesive that is specifically designed for windows to fix cracks. Loctite Super Glue Glass is a good choice. This high-tech adhesive is designed to adhere to glass and then dries crystal clear for the perfect finish. Apply it to the crack and allow it dry completely before applying another layer.
Stress cracks are a different problem that can happen to your glass window. They're typically caused by dramatic changes in temperature, and they can quickly spread across the entire glass window if they aren't repaired. To prevent stress cracks create an arc using glass cutters close to the crack. This will stop the crack from spreading and may slow it down by a day or two.
If you're replacing a damaged window take measurements of the frame to determine the size of 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 cutting your new glass, apply glaziers compound around the edges of the frame and glass. Once the compound dries then paint it over it to match the frame of the window.

Condensation on the inside of double-glazed windows is typically an indication that a seal on the window unit has failed. This is a serious issue since it means that heat from your home is lost through the window, and can be costly for you and your energy bills.

But, if the glass is colder or colder than the frame then condensation will build up on it, which can damage the window. If you notice condensation on your double-glazed window and you cannot resolve it by opening the windows, by using extractor fans, dehumidifiers, or by trickle venting, you might need to contact an expert.
Condensation on the exterior of double-glazed windows is rare, but it can occur if the seal has begun to weaken between the glass and the frame. It's more frequent during winter, when the temperature is lower. This makes it easier for condensation to form. The most likely cause is a flaw in the spacer placed between the window and the frame. This spacer often contains desiccant that is extremely absorbent and absorbs excess moisture.
This could lead to moisture seeping through the gap once the desiccant is saturated. This could cause condensation and water to build in the gap which is difficult to clean out.
Most reputable window companies provide a guarantee and will replace the glass and unit of a window if it's damaged by condensation. Make sure to report any issues as soon as possible to your window installer to ensure that the condensation is repaired as fast as possible to avoid further damage.

It's also recommended to wash the rabbet prior to starting, which is the part of the frame around the window frame that is where glass is likely to go. Apply a coat linseed to the rabbet and then wipe it clean. This will aid in helping the putty to stick.
After the frame has been cleaned and the rabbet in place, it's time to plan the replacement of the damaged pane. Get a piece made of double strength glass that is 1/8 inch smaller in both directions. You'll also need to purchase glass points, which are steel triangles which hold the glass in the right place.
With the window sash taken off using a flat pry-bar to gently pull the sash free of the moulding of wood. It is possible to scrape old glazing off using a utility blade or chisel. Utilize the heat gun to warm any putty which cannot be easily removed. This will make it easier to peel off.
Once the frame is free from the molding and the frame is firmly pressed, gently press the glass in its new location. Then, with a glazier's or putty knife's point, fill in the gaps around it and smooth the edges. Once the putty is dry, paint the frame to match. Paint the glass and the compound by overlapping the paint slightly.
