It is possible to repair the glass that is cracked without replacing the entire window. Wear safety glasses and gloves. You can also employ duct tape or a painter's tape to make an X on the glass you want to remove. This will prevent any shattered glass from falling onto your work surface as you work. If you've noticed a small scratch in your window glass you can cover it with tape to keep out water, wind and insects. 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, you should use an extra-strong plastic cover such as a tarp or a trash bag, to keep the glass in place until you can get a permanent fix.

This high-tech glue is designed to attach to glass and then dry transparent to give a perfect finish. Apply it to the crack in the glass, and let it dry completely before applying a second layer. Glass windows can also develop stress cracks. Stress cracks are typically caused by drastic temperature changes and can rapidly spread across the entire window if not fixed. To prevent stress fractures using a glass cutter, you need to score a small arc close to the crack. This stops the crack from spreading, and can slow it down by a day or so. If you're replacing an old window take measurements of the frame to determine the size of the new pane. It should be slightly larger than the opening in order to allow for expansion and contracting and to account for any imperfections that may occur on the frame or the glass. Once you've cut the glass to the proper 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 glazing window repairs Glazed Windows Condensation Inside Condensation on the interior of double-glazed windows is usually an indication that a seal around the window unit has failed. This is a serious issue as it means that the heat that is coming from your home is lost through the window, and could be costly for you and your energy bills. Double glazing is designed to prevent heat transfer between two panes, by sandwiching an air or vacuum layer between them. This creates a tight seal that blocks warm air from escaping. If the glass is cooler than the frame, condensation could form on the glass and cause damage to the window. If you're unable to solve condensation issues on a double-glazed window by opening windows by using extractors, dehumidifiers or trickle venting, you may require an expert. Condensation on the exterior of double-glazed windows is not common, but it can occur if the seal has begun to deteriorate between the glass and the frame. This is more common in winter as the temperature is lower and it's more easy for condensation to form. The primary reason for this is a flaw in the spacer that is used between the window and the frame. The spacer is filled with desiccant which is very absorbent and absorbs any excess moisture. This can lead to moisture leaking into the gap once the desiccant has been saturated. This could lead to condensation and water leaking into the gap and is very difficult to eliminate. Most reputable window companies offer a warranty and will replace the unit and glass of a window if it's damaged by condensation. Inform any issues as quickly as possible to the window manufacturer so that the condensation can be repaired as soon as possible to avoid further damage.
