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 with the window in place, however it is much simpler and quicker if you remove the frame and glass. This is also a great occasion to change the gaskets made of rubber.
Broken Glass
Glass that is cracked isn't just ugly, it can also let valuable sunlight and heat escape from your home. Fortunately, it's possible to fix a broken window without the need for a complete replacement.
Put on safety goggles and gloves. You can also use duct tape or painter's taps to create an "X" on the glass you plan to remove. This will prevent any broken glass from falling onto you as you work.
If you have a small crack in the glass of your window Cover it with tape to keep out rain, wind and insects. If the crack is only superficial, a single strip of tape will be enough. However in the event that the weather is expected to worsen before you can replace the window, you may need a more durable plastic cover such as an tarp or trash bag.
For cracks that aren't as deep try using a tough adhesive specifically designed for windows, such as Loctite Super Glue Glass. This high-tech glue is made to attach to glass and then dry transparent to give a perfect finish. Apply it to the crack in the glass, and let it dry completely before applying a new layer.
Stress cracks are a different issue that can occur to your glass window. Stress cracks are typically caused by drastic temperature changes and can spread rapidly across the entire window if not fixed. To stop stress fractures from occurring using a glass cutter, you need to cut a small circle near the crack. This will stop the crack from spreading, and may slow it down by a few days.
If you're replacing a damaged window make sure you measure the frame to fit the new pane. It should be slightly smaller than the opening to allow expansion and contraction and to cover any imperfections in the glass or frame. Once you've cut the glass to size apply glaziers' compound around the edges of both the frame and the glass. Once the compound dries paint it over to match the frame of the window.
Condensation on the inside of Double Glazed Windows
The appearance of condensation on the inside of double glazed windows usually indicates that the seal has been damaged at some point along the window unit. This is a serious issue as it means that heat from your home is being lost through the window and can be costly to both you and your energy bills.
New double glazing is designed to stop heat transfer between two panes of glass by sandwiching a layer air or a vacuum between them. This creates an airtight seal that keeps warm air from exiting the home. If the glass is warmer than the frame, condensation can develop on the glass and cause damage to the window. If you're unable to resolve condensation on windows with double glazing by opening windows by using extractors, dehumidifiers, or trickle venting, then you might require a professional.
Condensation on the exterior of double-glazed windows is not common However, it could happen when the seal has begun to break down between the glass and the frame. This is more frequent in winter when the temperature is lower and it's more easy for condensation to develop. This is caused by an issue with the spacer used between the frame and the window. The spacer is filled with desiccant which is highly absorbent and absorbs any moisture that is present.
The issue is that once the desiccant is saturated, it will start to break down, and eventually water can begin to leak through the gap between the glass units. This can result in condensation and water leaking into the gap, which is difficult to get rid of.
Most reputable window companies offer a warranty and will replace the unit and glass of the window if it is damaged by condensation. Make sure to report any issues as soon as possible to your window installer so that the condensation can be repaired as soon as possible to prevent further damage.

After the frame has been cleaned and the rabbet has been prepared, it is time to put together the replacement pane. Measure the height and width of the opening both ways Then, you can order an item of double-strength glass that is 1/8 inch shorter in both directions. You'll also need to purchase glass points, which are steel triangles that help to hold the glass in place.
With the window sash removed from the way, carefully pry it away from the wood molding using a flat pry bar. You may have to scrape old glazing putty off using a utility blade or chisel. Utilize the heat gun to warm any putty that won't come off easily. double glazing window repairs will make it much easier to remove it.
Once the frame has been free of the mold and the frame is firmly pressed, gently press the new glass into its new location.

It's not as difficult as you think to set up the new window. But, it's crucial to follow the directions provided by the manufacturer to ensure a proper fitting and long-lasting replacement. Use a wire brush to clean the frame of old paint or wood gunk, and then sand it down to bare wood, which will increase the seal between the frame and sash.
When putting the new pane in place, use the tip of your putty knife to gently bed the new window against the frame made of wood. Then, press the glazier's points into the frame every six inches to hold the window securely in the frame.
When the frame is cured, coat the new joint with several coats of paint that match the rest of the frame. Let the paint completely dry before you begin cleaning and maintaining your window.
