Glass windows may also develop stress cracks. Stress cracks are usually caused by extreme temperature fluctuations and can spread rapidly across the entire window if they are not repaired. To prevent stress cracks make an arc of a tiny size with a glass cutter near the crack. This will stop the crack from spreading and may slow it down by a day or so.
Examine the frame of the damaged window to determine the size of the new pane. It should be slightly larger than the opening to allow for expansion and contracting, as well as to make up for any imperfections in the frame or on the glass. Once you've cut your glass to size apply glaziers' compound around the edges of both the frame and the glass. Once the compound dries, paint over it to match the rest of the window frame.

If you are unable resolve condensation on double-glazed windows by opening windows by using extractors, dehumidifiers, or trickle venting, then you might require professional help.
It's rare for condensation to appear on the outside of double glazed windows but it can happen in the event that the seal between the glass and the window frame has started to deteriorate. This is more frequent in winter when the temperature is lower, making it more likely for condensation to develop. This is due to a defect in the spacer between the frame and the window. The spacer is often filled with desiccant that is highly absorptive and can absorb excess moisture.
The problem with this is that once the desiccant is saturated, it will start to break down and then water can begin to enter the gap between the glass units. This can cause condensation and water to build up in the gap, which is difficult to clean out.
The majority of reputable window manufacturers offer a warranty and will replace the unit and glass of a window in the event that it's damaged by condensation.

Find the height and width of the opening in both directions Then, you can order a piece of double-strength glass that's 1/8 inch shorter in both directions. You'll need to purchase glass points, which is a metal triangle that holds the glass in the right place.
With the window sash out of the way, carefully pull it away from the wood molding using a flat pry bar. You may have scrape off old glazing with a knife or chisel. Then you can use the heating gun to warm any putty that isn't able to come off. This will make it easier to remove.
Once the frame has been removed from the mold and the frame is pressed gently into the glass back into its place. Fill in the gaps with a glazier's tip or putty knife. Once the putty has dried paint it in a manner that matches the rest of the frame. Paint the glass and the compound by overlapping it slightly.
