Glazing Repair - How to Repair a Cracked Window Glazing can have a significant effect on the energy efficiency of your house. 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 is much faster and simpler when the frame and glass are removed. This is also an excellent occasion to replace the gaskets on the rubber. Broken Glass Glass that is cracked isn't just ugly, it can also let valuable heat and sunlight escape your home. Fortunately, it's often possible to repair a damaged window pane without the need for a complete replacement. Put on safety goggles and gloves. You can also use duct tape or painter's tap to create an X on the glass you want to remove. This prevents any shattered pieces from falling when you work, which could keep you from serious injuries. If you have a small crack in your window glass, cover it with tape to keep out rain, wind and insects. If the crack is superficial and only a single strip tape will be enough. However, if the weather is likely to get worse before you can replace the window, you might want to use a heavy-duty plastic cover like a trash bag or tarp. For cracks that aren't as deep Try using a strong adhesive designed specifically for windows, such as Loctite Super Glue Glass. This high-tech glue is made to bond to glass and dries crystal clear for the perfect finish. Apply it to the cracks in the glass and let it dry completely before applying a new layer. Glass windows may also develop stress cracks. Stress cracks are usually caused by drastic temperature changes and can quickly spread across the entire window if not repaired. To stop double glazing window repairs from occurring create an arc using glass cutters close to the crack. This stops the crack from advancing, and can slow it down by a day or so. If you're replacing an old window take measurements of the frame 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 glass to size apply glaziers' compound around the edges of the frame and the glass. After the compound has dried paint it over to match the rest of the window frame. Double Glazed Windows Condensation Inside Condensation on the interior of double-glazed windows is usually an indication that a seal on the window unit has failed. This is a serious issue and could mean that heat is being lost from your home through the window. Double glazing is designed to prevent heat transfer between two panes by sandwiching an air or vacuum layer between them. This creates a airtight seal and prevents warm air from leaving the house. If the glass is colder than the frame, condensation could develop on the glass and cause damage to the window. If you are unable to remove condensation from double-glazed windows by opening windows or using extractors, dehumidifiers or trickle venting, you might require a professional. It's much rarer for condensation to form on the outside of double glazed windows, however it can happen when the seal between the glass and window frame is beginning to break down. It's more frequent in winter, when the temperature is lower. This makes it easier for condensation to form. The main cause of this is a flaw in the spacer that is used between the window and the frame. This spacer often contains desiccant which is highly absorbent and will soak up excess moisture. This could lead to moisture leaking into the gap after the desiccant is saturated. This can result in water and condensation in the gap, and can be very difficult to eliminate. Most reputable window companies provide a guarantee and will replace the glass and unit of a window if it's damaged by condensation. It is essential to report any problems to your window installer when you notice them so that condensation can be fixed as quickly as possible to prevent further damage to the window unit and the frame surrounding it. Shattering Window Glass A damaged or cracked window is more than an aesthetic problem. It could also be a safety risk, especially if it is spreading. It is best to get it fixed as quickly as you can. Glass adhesives are available for window glass in your vehicle that can be purchased on the internet or in numerous auto maintenance shops. You can also apply a glazing compound for use at home that is available at most hardware and home improvement stores. Put on thick gloves and safety glasses before you start any work. Clean the area thoroughly to get rid of any large shards. Also, you should vacuum up any chips. This will prevent them from causing injury to you or a glass repair person later on. It is best to climb a ladder rather than on the ground. This will let you reach all the parts of the frame with ease and protect you from glass falling. Before you start, it's a good idea clean the rabbet. This is the area that glass will be placed. Apply a coat of linseed on the rabbet, then wipe it down. This will help the putty stick. After the frame has been cleaned and the rabbet ready, it's time to prepare for the replacement of the broken pane. Measure the height and width of the opening in both directions, then order an item of double-strength glass that's 1/8 inch shorter in both directions. You'll need glass points which is a steel triangle that keeps the glass in the right place. After removing the window sash, use a flat pry-bar to gently pry the sash away from the wood moulding. You may have to scrape old glazing off with a utility blade or chisel. Then you can use the heat gun to warm any putty that isn't able to fall off. This will make it easier to peel it off. After the frame is removed from the molding and the frame is pressed gently into the new glass in its place. Then, using a putty knife or glazier's point, fill the gaps around it and smooth them out. Once the putty is dry, paint the frame in a similar color to the putty. Paint the glass and the compound by overlapping the paint slightly. Replacement Window Glass If you're replacing a broken window pane, first wear gloves and eye protection to protect yourself from glass shatters. Tape off the area surrounding the broken window to prevent it from breaking again in a different spot when you remove it. Begin by removing the old glazing compound and glazing points (small metal triangles) from the frame with a utility knife. Clean the frame opening and then apply a coat linseed to help the new putty adhere better. Once the frame is prepared, measure it to determine the size of a new windowpane. Then, you can purchase it at a home improvement retailer or other retailer. Be sure to purchase the pane at least 1/6th inch smaller in every direction than the measurement to allow for an ideal fit. It's much easier than you think to install windows that are new. But, it's important to follow the instructions provided by the manufacturer to ensure a proper fit and a long-lasting replacement pane. Use a wire brush to clean the frame opening of any old paint or wood gunk and then sand it to bare wood, which will improve the seal between the frame and sash. When you're putting the new pane in place, use the point of your putty knife to gently bed the new window against the wood frame. Then, press glazier's points into the frame approximately every six inches to hold the window securely in place. After the frame has cure, paint the joint with a few coats of paint to match the rest of the frame. Let the paint completely dry before proceeding to cleaning and maintaining your window. Maintaining your windows in good condition and ensuring that they function correctly will extend their lifespan and increase the energy efficiency of your home. If your windows are old or are in poor condition then you might be better off having replacing your windows completely. If you opt for this option, we suggest choosing a high-quality insulated windows to lower your energy costs. The type of window that you select will also impact the total cost of your project.
