Glazing Repair - How to Repair a Cracked Window
Glazing can make a big impact on the energy efficiency of your home. This is particularly true for older double-glazed windows.
It is possible to replace glazing points by putting the window in place, but it is much easier and faster if you take off the glass and frame. This is also an excellent chance to change the gaskets made of rubber.
Broken Glass
Broken glass isn't just unattractive but it also allows valuable heat and sunlight escape from your home. It is possible to repair the glass that is cracked without replacing the entire window.
Wear safety goggles and gloves. You should also put a piece of tape with an "X" shape on the glass you intend to remove (duct or painter's tap works well). This will stop any broken glass from falling on your work surface as you work.
If you have a small scratch in your window glass Cover it with tape to keep out the elements like wind, water and insects. If the crack is superficial just a single strip of tape will suffice. However should the weather be expected to worsen before you can replace the window, you might need a more durable plastic cover, such as the trash bag or tarp.
Use a strong adhesive that is designed for windows to fix cracks. Loctite Super Glue Glass is a good choice. This high-tech glue was designed to attach to glass and then dry clear for a flawless finish. Apply it to the crack and let it completely dry before applying a new layer.
Stress cracks are another common problem that can happen to your glass window. They are usually caused by large changes in temperature, and can spread quickly across the entire glass window if it's not treated. To prevent stress cracks create an arc of a tiny size with glass cutters near the crack. This will stop the crack from advancing, and may slow it down by a few days.
If you're replacing a damaged window, measure the frame for the new pane. It should be slightly bigger than the opening in order to allow for expansion and contraction and to account for any imperfections on the frame or the glass. After you've cut your glass to the proper size, apply glaziers' compound around the edges of the frame and the glass. Once the compound is dry, paint over it to match the rest of the window frame.
Double Glazed Windows Condensation Inside
Condensation inside double-glazed windows is usually an indication that the seal around the window unit has failed. This is a major issue because it could mean that heat is being lost from your home through the window.
Double glazing has been designed to stop heat transfer between the two glass panes by sandwiching a layer air or a vacuum between them. This creates an airtight seal and stops warm air from escaping the house. If the glass is cooler than the frame, condensation can develop on the glass and cause damage to the window. If you've got condensation on your double glazed window and you cannot resolve it by opening the windows with extractor fans, using dehumidifiers, or by trickle venting then you may need to contact a professional.
Condensation on the exterior of double-glazed windows is rare however it can happen when the seal has started to break down between the glass and the window frame. It is more prevalent in winter, when temperature is lower. This makes it easier to create condensation. This is caused by an issue with the spacer between the frame and the window. This spacer often contains desiccant which is highly absorbent and will soak up excess moisture.
The issue is that once the desiccant becomes saturated it begins to break down and moisture can start to enter the gap between the glass units. This can cause condensation and water to build up in the gap, which is difficult to remove.
The positive side is that many reliable window companies will provide a warranty on their products. They will replace the window unit and glass in the event of damage caused by condensation. It is crucial to report any issues to your window installer when you notice them so that condensation can be addressed as quickly as possible in order to prevent further damage to the window unit as well as the frame around it.
Shattering Window Glass
A window that is cracked isn't just a cosmetic issue, it can also present a security risk particularly if the crack is growing. It is best to have it fixed as soon as possible.

It's a good idea work from a ladder, instead of standing on the floor. This will enable you to reach all parts of the frame with ease and will protect yourself from glass falling. It's also a good idea to clean the rabbet prior to starting, which is the part of the frame around the window frame, where the glass will go. Wipe it down and then apply a coat of linseed oil to the rabbet, which will allow the new putty to stick to the frame securely.
Once the frame is cleaned and the rabbet is ready, it's time to prepare for the replacement of the damaged pane. Get a piece made of double strength glass that is one inch smaller in both directions. You'll need to buy glass points, which is a metal triangle that keeps the glass in place.
After removing the window sash using a flat pry-bar to carefully pry the sash away from the moulding of wood. It is possible scrape off old glazing putty with a knife or chisel. Utilize the heat gun to warm any putty which isn't able to be removed easily. This will make it easier to remove.
After the frame is removed from the mold then gently press the new glass in its place. Fill in the gaps with a glazier's tip or putty knife. Once the putty is dry, paint the frame to match. Paint a little bit over the edge of the compound and onto the glass to completely seal it.
Replacement Window Glass
If you're replacing a damaged window, be sure to wear gloves and eye protection to shield yourself from glass shatters. Tape off the area surrounding the broken window to prevent it from shattering in a different spot when you remove it.
Start by removing the old glaze compound and glazing points (small metal triangles) from the sash frame using a utility knife. Clean the entire opening of the frame and then apply a layer of linseed to aid in adhering the new putty better.
Once the frame has been prepared, measure it to determine the dimensions of a new windowpane. Then, purchase it from a home improvement retailer or another retailer. The panes should be 1/6th inch smaller in each direction than your measurement. This will ensure a snug fit.
It's not as difficult as you think to install the new window. But, it's crucial to follow the directions provided by the manufacturer to ensure a perfect fitting and long-lasting replacement. Make use of a wirebrush to clean any old paint or wood gunk from the frame's opening. Then sand the wood down to the bare wood in order to strengthen the seal.
Use the point of the putty blade when putting in the new pane to bed it lightly against the frame of wood. Then, press glazier's facets into the frame approximately every six inches to secure the new window securely in place.
Once the frame is cured and the joint is painted, you can paint it several times to match the frame. Let the paint dry completely before moving on to cleaning and maintaining your window.
