Glazing Repair - How to Repair a Cracked Window
Glazing can have a significant impact on the efficiency of your home. This is particularly important for older double-glazed Windows.
While it is possible to replace the glazing points while the window is still in position, it is simpler and quicker if the glass and frame are removed. It is a good time to replace the rubber seals.
Broken Glass
Cracked windows aren't just unsightly but can also let valuable sunlight and heat to escape your home. It's possible to fix damaged glass without having to replace the entire window.
Put on safety goggles and gloves. double glazing repairs should also put a piece of tape in an "X" shape on the glass you intend to remove (duct or painter's tape works well). This prevents any shattered pieces from falling when you work, which can save you from serious injury.
If you have a small crack in your window glass you can cover it with tape to block water, wind, and insects. One strip of tape should be enough to cover any cracks that are superficial but if you're worried about the weather becoming worse before you can replace your window, consider using a more durable plastic cover like a tarp, or a garbage bag, to keep the glass in place until you can obtain a permanent fix.
For cracks that aren't as shallow try using a tough adhesive that is specifically designed for windows, such as Loctite Super Glue Glass. This high-tech adhesive is formulated to adhere to glass and then dries crystal clear for the perfect finish. Apply it to the cracks in the glass and allow it to dry completely before applying a second layer.
Glass windows may also develop stress cracks. They're usually caused by significant changes in temperature, and can spread quickly across the entire glass window if it's not repaired. To prevent stress cracks make an arc of a tiny size with glass cutters close to the crack. This stops the crack from spreading and can slow it down by a few days.
Examine the frame of the broken window to determine the size of the new pane. It should be slightly bigger than the opening in order to allow for expansion and contracting, as well as to make up for any imperfections that may occur on the frame or on the glass. Once you've cut your new glass to size apply glaziers' compound around the edges of the frame and the glass. Once the compound has dried paint it to match the frame.
Condensation on the inside of Double Glazed Windows
Condensation on the inside of double-glazed windows is typically an indication that a seal on the window unit has failed. This is an important issue as 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.
New double glazing is designed to block heat transfer between the two panes of glass by sandwiching a layer of air or vacuum between them. This creates a airtight seal and keeps warm air from exiting the home. But, if the glass is cold or colder than the surrounding frame, then condensation can build up on it, which can damage the window. If you notice condensation on your double-glazed window and you are unable to resolve it by opening the windows with extractor fans, using dehumidifiers or by trickle venting, you might require the help of a professional.
Condensation on the outside of double-glazed windows is not common However, it could happen when the seal has started to break down between the glass and the frame. This is more prevalent in winter, when the temperature is lower, making it more easy for condensation to develop. The primary reason for this is a fault in the spacer placed between the frame and the window. The spacer is often filled with desiccant that is extremely absorbent and can absorb excess moisture.
This could lead to moisture leaking into the gap after the desiccant is saturated. This can lead to water and condensation in the gap, which is difficult to get rid of.
The good news is that most reliable window companies will provide warranties on their products. They will replace the glass and window unit in the event of damage caused by condensation. It's essential to report any issues to your window installer when you notice them so that condensation can be addressed as soon as possible in order to prevent further damage to the window unit as well as the frame around it.

Before you begin, it's a good idea clean the rabbet. This is the area that glass will be placed. Wipe it down and then apply an oil coat of linseed to the rabbet, which will allow the new putty to stick securely.
After the frame has been cleaned and the rabbet is prepared, it is time to put together the replacement pane. Take measurements of the width and height of the opening in both directions, then order the double-strength piece of glass that is 1/8 inch shorter in both directions. You'll also need glass points, which are made of metal triangles which keep the glass in the right place.
After removing the window sash using a flat pry-bar to gently pull the sash away from the moulding of wood. You may have scrape off old glazing putty with a utility knife or chisel. Then make use of the heat gun to warm up any putty that isn't able to fall off. This will make it much easier to remove it.

Use a wire brush to clear the frame of old paint or wood gunk, and then sand it to bare wood to enhance the seal between the sash and frame.
Use the point of the putty knife when inserting the new pane to lay it gently against the wood frame. Put glazier's tips in the frame every six inches. This will hold the new pane securely in the frame.
