Glazing Repair - How to Repair a Cracked Window
Glazing can make a significant difference in the energy efficiency of your home. This is particularly true for older double-glazed windows.
It is possible to replace the glazing points by putting the window still in place, but it is much easier and quicker if you remove the glass and frame. This is also a great chance to replace the rubber gaskets.
Broken Glass
Windows that are cracked aren't just unsightly but can also let valuable heat and sunlight to escape your home. Fortunately, it's possible to repair a broken window without having to go through a full replacement.
Start by putting on protective gloves and safety goggles. Also, you should put a piece of tape in an "X" shape on the glass you intend to remove (duct or painter's tap works well). This prevents any shattered pieces from falling as you work, which could keep you from serious injuries.
Cover a small crack in your window glass with tape to keep insects, water and wind out. One strip of tape should be sufficient for cracks with a superficial appearance but if you're worried about the weather getting worse before you can replace your window, consider using a heavier-duty plastic cover, like a tarp or trash bag, to hold the glass in place until you obtain a permanent fix.
For cracks that aren't as shallow, try using a strong adhesive that is specifically designed for windows, such as Loctite Super Glue Glass. This high-tech glue was designed to bond to glass and dries clear for a flawless finish. Apply it to the cracks in the glass, and let it dry completely before applying another layer.
Glass windows may also develop stress cracks. Stress cracks are usually caused by large temperature changes and can quickly spread across the entire window if they are not repaired. To stop stress fractures from occurring using a glass cutter, you need to cut a small circle near the crack. This can prevent the crack from spreading and can slow it down for a few days.
Examine the frame of the damaged window to determine the size of the new pane. It should be slightly smaller than the opening to allow expansion and contraction and to cover any imperfections in the frame or glass. Once you've cut your glass to the proper size apply glaziers' compound around the edges of both the frame and the glass. After the compound has dried then paint it over it to match the frame of the window.
Condensation inside of Double Glazed Windows
The appearance of condensation on the inside of double-glazed windows typically indicates that the seal has failed at some point along the window unit. This is a serious issue because it indicates that heat from your home is lost through the window and can be costly for you and your energy bills.
Double glazing is designed to block heat transfer between two panes by sandwiching an air or vacuum layer between them. This creates a tight seal that stops warm air from venting. But, if the glass is cold or colder than the surrounding frame, then condensation can form on it and cause damage to the window. If you notice condensation on your double glazed window that you are unable to eliminate it by opening the windows, by using extractor fans, dehumidifiers or by trickle venting, then you may need to call in a professional.
It's rare to see condensation appear on the exterior of double-glazed windows, but it could occur in the event that the seal between the glass and window frame is beginning to break down. This is more common in winter as the temperature is lower, making it easier for condensation to form. This is due to an issue with the spacer between the frame and the window. The spacer is made up of desiccant which is highly absorbent and absorbs any moisture that is present.
The problem with this is that when the desiccant is saturated, it will begin to break down and then moisture can start to leak through the gap between the glass units. This could cause condensation and water to build within the gap, which is difficult to remove.
The good news is that the majority of reputable window companies will offer warranties on their products. They should replace the glass and window unit in the event of damage caused by condensation. Make sure to report any issues as soon as possible to your window installer so that the condensation is repaired as soon as it can to avoid further damage.

Clean it off and then apply the linseed oil to the rabbet. This will allow the new putty to stick in place.
Once the frame is cleaned and the rabbet ready, it's time to prepare for the replacement of the damaged pane. Measure the height and width of the opening both ways and then purchase the double-strength piece of glass that is 1/8 inch smaller in both directions. You'll need to buy glass points, which is a metal triangle that keeps the glass in place.
With the window sash out of the way, carefully pry it away from the wood molding with an angled pry bar. You may need scrape off old glazing putty with a utility knife or chisel. Make use of the heat gun to warm any putty that cannot be easily removed. This will make it easier to remove it.
When the frame is out of the molding and the frame is firmly pressed, gently press the new glass into its new location. Then, using a glazier's or putty knife's point, fill in the gaps around it and smooth the edges. When the putty is dry, paint it to match the rest of the frame.

It's easier than you think to set up windows that are new. But, it's crucial to follow the directions that are provided by the manufacturer in order to ensure a good fitting and long-lasting replacement. Use a wirebrush to remove any old paint or wood gunk from the frame's opening. Then sand the wood to the wood's surface to improve the seal.
When putting the new pane in place, use the point of your putty knife to gently lay the new window against the frame made of wood. Then, press glazier's facets into the frame every six inches to hold the window securely in the frame.
