Broken Glass
Broken glass isn't just unattractive, it can also let valuable sunlight and heat escape from your home. It's possible to fix the glass that is cracked without replacing the entire window.

For cracks that aren't quite as shallow try using a tough adhesive specifically designed for windows, like Loctite Super Glue Glass. This high-tech glue is made to bond to glass and 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 typically caused by extreme temperature fluctuations and can quickly spread across the entire window if not addressed. To prevent stress cracks make a small arc with a glass cutter near the crack. This will stop the crack from spreading and slow it down for a few days.
If you're replacing a broken window, measure the frame for the new pane. It should be slightly smaller than the opening to allow expansion and contraction and to compensate for any imperfections in the frame or glass. Once you've cut your new glass to size apply glaziers' compound around the edges of both the frame and the glass. Once the compound is dry, paint it to match the frame.

Condensation on the outside of double-glazed windows is uncommon However, it could happen when the seal has begun to break down between the glass and the window frame. It is more prevalent during winter, when the temperature is lower. This makes it easier for condensation. The primary reason for this is a fault in the spacer that is used between the frame and the window. This spacer often contains desiccant that is highly absorptive and will soak up excess moisture.
The issue is that when the desiccant gets saturated, it will begin to break down and then moisture can start to seep through the gap between the glass units. This can result in condensation and water in the gap, which is difficult to get rid of.
The positive side is that many reputable window companies will offer warranties on their products. They should replace the window unit and glass if it has been damaged by condensation. It's essential to notify your window installer immediately you notice them, so that condensation can be fixed as quickly as possible in order to prevent further damage to the window unit as well as the frame around it.

Also, you'll need to purchase glass points, which are made of metal triangles that help to hold the glass in the right place.
With the window sash removed from the way, carefully pry it off of the wood molding using a straight pry bar. You may have to scrape old glazing putty off with a utility blade or chisel. Then you can use the heating gun to warm any putty that won't easily be removed. This will make it easier to remove.
When the frame is out of the molding and the frame is firmly pressed, gently press the glass in the frame. Then, with a putty knife or glazier's point, fill the gaps around it and smooth the edges.
