Glazing Repair - How to Repair a Cracked Window
Glazing can have a significant impact on the efficiency of your home. This is particularly true for older double-glazed windows.
While it is possible to change the glazing points while the window is still in place, it's quicker and easier if the glass and frame are removed. This is also a good opportunity to replace the gaskets on the rubber.
Broken Glass
Cracked windows aren't just ugly, but they can also allow valuable sunlight and heat to escape your home. Fortunately, it's often possible to repair a broken window pane without the need for a complete replacement.
Start by putting on protective gloves and safety goggles. You should also place a piece of tape with an "X" shape on the glass you plan to remove (duct or painter's tape works well). This will stop any broken pieces from falling while you work, which can save you from serious injury.
If you've got a tiny crack in the glass of your window you can cover it with tape to block the elements like wind, water and insects. If the crack is superficial, a single strip of tape is enough. However in the event that the weather is expected to worsen before you can replace the window, you might need a more durable plastic cover like the trash bag or tarp.
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 adhesive is formulated to adhere to glass and then dries crystal clear for an ideal 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 typically caused by dramatic temperature fluctuations, and can spread quickly across the entire glass window if not treated. To prevent stress fractures that result from stress, use a glass cutting tool to cut a small circle close to the crack. This stops the crack from advancing, and can reduce the size by a day or two.
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 for expansion and contraction, and to compensate for any imperfections in the glass or frame. Once you've cut your new glass to size apply glaziers' compounds around the edges of the frame and the glass. Once the compound has dried, paint it to match the frame.
Double Glazed Windows Condensation Inside
Condensation on the interior of double-glazed windows is typically an indication that the seal around the window unit has failed. This is a serious problem, as it can indicate that heat is lost from your home through the window.
Double glazing has been designed to stop heat transfer between two glass panes by sandwiching a layer of air or a vacuum between them. This creates a seal that blocks warm air from venting. If the glass is warmer than the frame, condensation can form on the glass and cause damage to the window. If you've got condensation on your double-glazed window and you are unable to resolve it by opening the windows, by using extractor fans, dehumidifiers or by trickle venting, then you may need to contact an expert.
Condensation on the exterior of double-glazed windows is not common however it can 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 and it's more likely for condensation to develop. The most likely cause is a defect in the spacer that is placed between the frame and the window. This spacer contains desiccant, which is very absorbent and will absorb any excess moisture.
This could lead to moisture seeping through the gap once the desiccant is saturated. This can lead to condensation and water in the gap and is very difficult to eliminate.
Most reputable window companies offer a warranty and replace the glass and unit of a window if it is damaged by condensation. It's essential to report any issues to your window installer when you notice them so that condensation can be fixed as quickly as possible in order to prevent further damage to the window unit and the surrounding frame.
Shattering Window Glass
A cracked window pane could be more than an aesthetic problem. It could also be a safety risk, especially if it is spreading. It's best to have it fixed as quickly as you can. You can use glass adhesives for windows in vehicles that can be purchased online or in numerous auto maintenance shops. You can also make use of a glazing compound for home use that is available at most hardware and home improvement stores.
Put on your gloves with a thick layer of protection and safety glasses before you start any task. Clean the area thoroughly to remove any large shards. You'll also want to remove any chips that have fallen. This will prevent them from cutting you or a glass repair worker later on.
It is better to stand on a ladder than on the ground. This will make it easier to reach all areas of the frame, and will ensure that you are safe from falling glass. Before you start it's best to clean the rabbet. This is the area where glass is placed. Apply a coat of linseed on the rabbet, then wipe it down. This will aid in helping the putty stick.
Once the frame is cleaned and the rabbet in place, it's time to get ready for the replacement of the broken pane. Measure the height and width of the opening in both directions Then, you can order the double-strength piece of glass that is 1/8 inch smaller in both directions. You'll also need glass points, which are metal triangles that help to hold the glass in place.
After removing the window sash and the pry-bar flat, use it to gently pry the sash off of the wood moulding. You may need to scrape old glazing putty off with a utility blade or chisel. Use the heat gun to warm any putty that cannot be easily removed. This will make it easier to remove.
Once the frame has been free from the molding and the frame is firmly pressed, gently press the glass in its place. Then, using the help of a putty knife or glazier's point, fill the gaps around it and smooth them out. After the putty has dried paint the frame in a similar color to the putty. Paint it slightly over the edge of the compound and onto the glass to completely seal it.
Replacement Window Glass
Wear protective eyewear and gloves when replacing a broken pane of glass. Tape off the area around the broken window to stop it from shattering in a different area after you remove it.
Begin by removing the old glaze compound and glazing points (small metal triangles) from the frame using a knife. Clean the entire frame opening, and then apply a layer of linseed to make sure the new glue sticks better.
Once the frame is in place, take measurements for the new window pane. Then purchase it from a local home improvement store or other retailer. Be sure to purchase the pane 1/6th inch shorter in each direction than your measurement to allow for a snug fit.

But, it's important to follow the instructions that are provided by the manufacturer in order to ensure a perfect fit and a long-lasting replacement pane. Use a wirebrush for removing any paint or wood gunk from the frame's opening. Then sand the wood until it is the wood's surface to improve the seal.
Make use of the point of the putty knife when putting in the new pane to lightly place it against the frame of wood. Press glazier's tips into the frame every six inches. This will help hold the new window securely in position.
After the frame has cured and the joint is painted, you can paint it several times to match the frame. Allow the paint to dry completely before cleaning and maintaining your windows.
