This high-tech glue is made to bond to glass, and then dries crystal clear for an ideal finish. Apply it to the crack, and let it completely dry before applying a new layer.
Glass windows can also develop stress cracks. Stress cracks are usually caused by drastic temperature changes and can spread rapidly across the entire window if not fixed. To avoid stress fractures, use a glass cutter to score a small arc close to the crack. This will prevent the crack from expanding and reducing the severity for several days.
If you're replacing a broken window make sure you measure the frame to fit the new pane.

Condensation on the inside of double-glazed windows is typically an indication that a seal along the window unit has failed. This is a serious problem because it could mean that heat is being lost from your home through the window.
New double glazing is designed to stop heat transfer between two glass panes by sandwiching a layer air or vacuum between them. This creates a seal that prevents warm air from venting. If the glass is colder or colder than the surrounding frame, then condensation can build up on it and damage the window. If you notice condensation on your double-glazed window and you cannot resolve it by opening the windows, using extractor fans, using dehumidifiers or by trickle venting, then you may need to call in a professional.
It's rare to see condensation appear on the outside of double glazed windows but it can happen when the seal between the glass and frame is beginning to break down. This is more frequent in winter, when the temperatures are lower and it's more easy for condensation to develop. This is due to an issue with the spacer used between the frame and the window. The spacer is made up of desiccant which is extremely absorbent and absorbs any moisture that is present.
The issue is that when the desiccant gets saturated, it begins to break down, and eventually water can begin to enter the gap between the glass units. This could cause condensation and water to build in the gap which is difficult to remove.
The good news is that most reliable window companies will provide a warranty on their products. They will replace the glass and window unit if it has been damaged by condensation. It is essential to report any issues to your window installer as soon as you notice them so that condensation can be fixed promptly in order to prevent further damage to the window unit as well as the surrounding frame.

Measure the height and width of the opening both ways, then order an item of double-strength glass that is 1/8 inch shorter in both directions. Also, you'll need to purchase glass points, which are metal triangles that keep the glass in place.
With the window sash removed and the pry-bar flat, use it to gently pull the sash away from the wood moulding. You may need to scrape old glazing putty off using a utility knife or chisel. Then you can use the heat gun to warm up any putty that won't easily fall off. This will make it easier to peel off.
