double glazing window repairs - How to Repair a Cracked Window
Glazing can make a big impact on the energy efficiency of your home. This is especially true in older double-glazed windows.
While it is possible to replace the glazing points when the window is still in place, it is much simpler and quicker when the frame and glass are removed. This is also an excellent occasion to replace the gaskets on the rubber.
Broken Glass
Cracked windows aren't just unsightly but can also allow valuable heat and sunshine to escape your home. It is possible to repair a broken pane of glass without having to replace the entire window.
Start by putting on protective gloves and safety goggles. You can also apply duct tape or painter's tap to create an "X" on the glass that you intend to remove. This will stop any broken pieces from falling when you work, which could protect you from serious injury.
Cover a small crack in your window glass with tape to keep bugs, water, and wind out. One strip of tape is enough for superficial cracks, but if you're worried about the weather becoming worse before you can replace your window, use an extra-strong plastic cover like a tarp or trash bag, to keep the glass in place until you get a permanent fix.
For cracks that aren't as shallow Try using a strong adhesive that is specifically designed for windows, like Loctite Super Glue Glass. This high-tech glue is made to adhere to glass and then dries crystal clear for the perfect finish. Apply it to the crack, and let it dry completely before applying a new layer.
Glass windows may also develop stress cracks. They are usually caused by large temperature fluctuations, and they can quickly spread across the entire glass window if they aren't repaired. To stop stress cracks from occurring, score a small arc with glass cutters near the crack. This stops the crack from spreading, and can reduce the size by a day or so.
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 cover any imperfections in the glass or frame. Once you've cut the new glass to size apply glaziers' compound around the edges of both the frame and the glass. Once the compound is dry, paint it to match the frame.
Condensation inside of Double Glazed Windows
Condensation on the interior of double-glazed windows is usually an indication that the seal along the window unit has failed. This is a serious issue as it means that the heat that is coming from your home is lost through the window, and can be costly for you and your energy bills.
New double glazing is designed to stop heat transfer between two panes of glass by sandwiching a layer of air or a vacuum between them. This creates a secure seal that blocks warm air from venting. If the glass is warmer than the frame, condensation will form on the glass and cause damage to the window. If you have condensation on your double-glazed window and you cannot resolve it by opening the windows, with extractor fans, using dehumidifiers or trickle venting, you might need to contact a professional.
It's much rarer to see condensation appear on the outside of double glazed windows, however it can occur if the seal between the glass and window frame is beginning to break down. This is more prevalent in winter when the temperature is lower and it's more easy for condensation to form. This is due to an issue in the spacer between the frame and the window. The spacer is often filled with desiccant which is highly absorbent and can absorb excess moisture.
The problem with this is that when the desiccant gets saturated, it begins to break down and moisture will begin to leak through the gap between the glass units. This can cause condensation and water to build within the gap, which is difficult to clean out.
Most reputable window companies offer a warranty and replace the unit and glass of a window in the event that it's damaged due to condensation. Report any problems as soon as you can to the window manufacturer so that the condensation can be repaired as soon as it can to avoid further damage.
Shattering Window Glass
A cracked window pane is more than an aesthetic issue. It could also pose a safety risk, especially when it's spreading. It is recommended to get it repaired as quickly as possible. There are several methods to fix it, including using glass adhesives specifically designed for windows in vehicles, which can be purchased online or at many auto maintenance stores. You can also apply a glazing compound for home use that is available at most hardware and home improvement stores.
Put on a thick pair of gloves and safety glasses before you begin any work. Clean the area thoroughly to remove any large shards. You should also vacuum up any chips. This will stop them from cutting yourself or a glass repair technician in the future.
It's a good idea climb a ladder instead of standing on the floor. This will allow you to reach all the areas of the frame, and will protect you from falling glass. Before you begin, it's a good idea clean the rabbet. This is the area that glass is placed. Clean it and then apply an oil coat of linseed to the rabbet. This will allow the new putty to stick securely.
After the frame has been cleaned and the rabbet ready, it's time to plan the replacement of the broken pane. Get a piece made of double strength glass that is 1/8 inch smaller in both directions. You'll need glass points, which is a metal triangle that holds the glass in the right place.
With the window sash removed from the way, carefully pry it away from the wood molding using a straight pry bar. It is possible to scrape old glazing off using a utility knife or chisel. Utilize the heat gun to warm any putty which won't come off easily. This will make it easier to peel it off.
Once the frame has been free from the molding, carefully press the new glass into the frame. Then, using a putty knife or glazier's point, fill the gaps around it and smooth the edges. Once the putty is dry paint the frame to match. Paint the glass and the compound by overlapping the paint slightly.
Replacement Window Glass
If you're replacing a broken window pane, first wear eye protection and gloves to shield yourself from glass shatters. Tape the window's edge to stop it from breaking once you take it off.
Start by removing the old glazing compound and glazing points (small metal triangles) from the frame with a utility knife. Clean the frame opening and apply a coat of linseed oil to help the new putty stick to it better.
Once the frame is ready, measure it for an entirely new window and buy it from a home improvement store or another retailer. Make sure to order the pane 1/6th inch shorter in every direction than the measurement to allow for a snug fit.
Installing the new window is easier than you think, but ensure you follow the manufacturer's directions to ensure a proper fit and a long-lasting life for your replacement pane. Use a wire brush to clean the frame opening of any old paint or wood gunk. then sand it to bare wood, which will improve the seal between the sash and frame.
Make use of the edge of the putty knife when installing the new window to lightly place it against the wood frame. Then, press the glazier's points into the frame approximately every six inches to keep the new window securely in the frame.
After the frame has cured, coat the new joint with several coats of paint to match the rest of the frame. Let the paint dry completely before you begin cleaning and maintaining your window. Maintaining your windows in good condition and ensuring they work correctly will extend their life expectancy and improve the energy efficiency of your home. If your windows are older or are in poor condition it is possible that you would prefer the complete replacement of your windows. If you decide to go this route, we suggest choosing the highest-quality, well-insulated window that will reduce the cost of your utility costs. The type of window you choose will also impact the total cost of your project.
