Glazing Repair - How to Repair a Cracked Window

While it is possible to replace glazing points while the window is in place, it's faster and simpler if the glass and frame are removed. It is a good time to replace the rubber seals.
Broken Glass
Cracked windows are not only unattractive, but also allow valuable sunlight and heat to escape your home. It's possible to fix a broken pane of glass without replacing the entire window.
Wear safety glasses and gloves. You can also apply duct tape or painter's tape to make an "X" on the glass that you intend to remove. This will stop any broken pieces from falling when you work, which could protect you from serious injury.
If you have a small crack in your window glass you can cover it with tape to block water, wind, and insects. One strip of tape is enough to cover any cracks that are superficial, but if you're worried about the weather getting worse before you can replace your window, you should use a more durable plastic cover such as a tarp or a trash bag, to keep the glass in place until you find a permanent solution.
Use an adhesive that is strong and designed for windows to fix cracks. Loctite Super Glue Glass is a good choice. This high-tech adhesive is formulated to adhere to glass and dries crystal clear for an ideal finish. Apply it to the cracks in the glass, and let it dry completely before applying another layer.
Glass windows may also develop stress cracks. They're typically caused by dramatic temperature fluctuations, and they can quickly spread across the entire glass window if they aren't fixed. To stop stress fractures from occurring using a glass cutter, you need to cut a small arc near the crack. This will prevent the crack from expanding and reducing the severity for several days.
Examine the frame of the damaged window to determine the size of the new pane. It should be slightly smaller than the opening to allow for expansion and contraction, and to make up for any imperfections in the frame or glass. Once you've cut your new glass to size apply glaziers' compound around the edges of the frame and the glass. Once the compound is dry paint it to match the frame.
Double Glazed Windows Condensation Inside

Double glazing is designed to stop heat transfer between two panes by sandwiching an air or vacuum layer between them. This creates an airtight seal that stops warm air from escaping the house. If the glass is colder or colder than the frame then condensation will accumulate on it and damage the window. If you have condensation on your double-glazed window and you are unable to resolve it by opening the windows, by using extractor fans, dehumidifiers, or by trickle venting then you may need to call in an expert.
Condensation on the outside of double-glazed windows is rare, but it can occur when the seal has begun to break down between the glass and the frame. It is more common in winter, when temperature is lower. This makes it easier to create condensation. This is caused by a defect in the spacer between the frame and the window. The spacer is filled with desiccant which is extremely absorbent and absorbs any moisture that is present.
This can lead to moisture leaking into the gap when the desiccant is saturated. This can result in water and condensation in the gap and is very difficult to eliminate.
The majority of reputable window manufacturers offer a warranty and will replace the unit and glass of a window if it is damaged by condensation. Inform any issues as quickly as you can to the window manufacturer so that the condensation is repaired as fast as it can to avoid further damage.
