Glass windows may also develop stress cracks. They're usually caused by significant changes in temperature, and can quickly spread across the entire glass window if they aren't treated. To avoid stress fractures, use a glass cutter to cut a small arc close to the crack. This will stop the crack from spreading and can slow it down by a day or so.

If you're replacing a broken window make sure you measure the frame to fit the new pane.

It is more common during winter, when the temperature is lower. This makes it easier for condensation. The main cause of this is a fault in the spacer that is used between the frame and the window. The spacer is made up of desiccant which is highly absorbent and will soak up any moisture that is present.

This can lead to moisture seeping through the gap when the desiccant is saturated. This could lead to condensation and water leaking into the gap, which is difficult to eliminate.

With the window sash out of the way, gently pry it away from the wood molding with a flat pry bar. You may need to scrape old glazing putty off using a utility blade or chisel. Use the heat gun to warm any putty that isn't able to be removed easily. This will make it easier to peel off.
