Broken Glass
Cracked glass isn't just unsightly but it also allows valuable sunlight and heat escape your home. It is possible to repair the glass that is cracked without having to replace the entire window.

They're typically caused by dramatic temperature fluctuations, and they can quickly spread across the entire glass window if they aren't treated. To avoid stress fractures using a glass cutter, you need 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.
Examine the frame of the broken window to determine the size of the new pane. It should be slightly smaller than the opening to allow for expansion and contraction and to make up for any imperfections in the glass or frame. After cutting your glass, apply glaziers compound around the edges of the frame and glass. Once the compound has dried, paint it to match the frame.
Condensation on the inside of Double Glazed Windows
Condensation on the interior of double-glazed windows is typically an indication that a seal around the window unit has failed. This is a significant issue since it means that the heat that is coming from your home is lost through the window and can be costly to both you and your energy bills.
Double glazing is designed to block heat transfer between two panes by putting an air or vacuum layer between them. This creates an airtight seal that prevents warm air from leaving the house. However, if the glass is colder or colder than the frame, then condensation can build up on it, which can damage the window. If you've got condensation on your double-glazed window and you cannot resolve it by opening the windows, using extractor fans, using dehumidifiers, or by trickle venting, you might need to contact an expert.
Condensation of the outside of double-glazed windows is not common however it can happen when the seal has begun to break down between the glass and the window frame. This is more common in winter, when the temperature is lower, making it more easy for condensation to form. This is caused by an issue in the spacer that is used between the frame and the window. This spacer contains desiccant, which is highly absorbent and absorbs any moisture that is present.
The issue is that when the desiccant gets saturated, it will start to break down, and eventually water can begin to leak through the gap between the glass units. This could lead to condensation and water in the gap, and can be very difficult to eliminate.
Most reputable window companies provide a guarantee and will replace the glass and unit of the window if it is damaged by condensation. Inform any issues as quickly as you can to the window manufacturer so that the condensation is repaired as fast as possible to avoid further damage.

Clean it off and then apply an oil coat of linseed to the rabbet. This will allow the new putty to stick to the frame securely.
After the frame has been cleaned and the rabbet has been prepared It's now time to prepare the replacement pane. Find the height and width of the opening both ways and then purchase a piece of double-strength glass that is 1/8 inch shorter in both directions. You'll also need glass points, which are made of metal triangles which hold the glass in the right place.
With the window sash removed from the way, gently pry it off of the wood molding with an angled pry bar. You may have to scrape old glazing putty off with a utility blade or chisel. Then you can use the heat gun to warm up any putty that doesn't fall off. This will make it easier to remove it.
Once the frame has been removed from the mold, gently press the new glass in its place. Then, with the help of a putty knife or glazier's point, fill the gaps around it and smooth the edges.
