Glazing Repair - How to Repair a Cracked Window
Glazing can make a significant difference to the energy efficiency of your home. This is especially true for older double-glazed Windows.
While it is possible to replace the glazing points when the window is still in place, it's quicker and easier when the frame and glass are removed. This is also a good chance to change the gaskets made of rubber.
Broken Glass
Windows that are cracked aren't just unattractive, but also allow valuable sunlight and heat to escape your home. It is possible to repair the glass that is cracked without replacing the entire window.
Wear safety glasses and gloves. You can also apply duct tape or painter's tape to make an "X" on the glass you plan to remove. This will prevent any broken glass from falling on you while you work.
If you've noticed a small crack in your window glass you can cover it with tape to keep out water, wind, and insects. One strip of tape should be enough for superficial cracks but if you're worried about the weather becoming worse before you can replace your window, you should use an extra-strong plastic cover like a tarp or trash bag, to keep the glass in place until you obtain a permanent fix.
Make sure you use an adhesive that is strong and designed for windows to fix cracks. Loctite Super Glue Glass is a good choice. This high-tech adhesive is designed to bond to glass and it dries crystal clear to give an ideal finish. Apply it to the crack, and let it completely dry before applying a new layer.
Glass windows can also develop stress cracks. They're typically caused by dramatic changes in temperature and they can quickly spread across the entire glass window if not fixed. To avoid stress fractures using a glass cutter, you need to score a small arc close to the crack. This will stop the crack from spreading, and may slow it down by a day or so.
Take a look at the frame of the damaged 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. After Hoddesdon window repairs cut your new glass to size apply glaziers' compound around the edges of both the frame and the glass. After the compound has dried, paint it to match the frame.
Double Glazed Windows Condensation Inside
Condensation on the inside of double-glazed windows is usually an indication that a seal around the window unit has failed. This is a serious issue and could indicate that heat is 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 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 need to call in a professional.
It's much rarer for condensation to appear on the outside of double glazed windows, however it can occur if the seal between the glass and frame is beginning to break down. It is more common during winter, when the temperature is lower. This makes it easier to create condensation. The primary reason for this is a defect in the spacer that is placed between the frame and the window. This spacer often contains desiccant that is highly absorptive and will soak up excess moisture.
This could result in water leaking through the gap once the desiccant is saturated. This could lead to condensation and water in the gap, and can be very difficult to eliminate.
Most reputable window companies offer a warranty and replace the unit and glass of a window in the event that it is damaged by condensation. It's essential to report any problems to your window installer immediately you notice them so that condensation can be fixed as soon as possible to avoid 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 pose an injury risk, particularly if it is spreading. It's best to have it repaired as soon as possible. Glass adhesives can be used for window glass in your vehicle that you can buy on the internet or at many auto repair shops. Alternately, you can use a glazing compound intended for use in homes, which can be found at a variety of hardware or home improvement stores.
Put on thick gloves and safety goggles before you start any work. Clean the area thoroughly to get rid of any large shards. Also, you should clean up any chips that fell. This will stop them from cutting you or a glass repair technician later on.
It's a good idea to climb a ladder instead of standing 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. It's also a good idea to clean the rabbet prior to starting to the area around the perimeter of the window frame, where glass will be. Clean it and then apply a coat of linseed oil to the rabbet. This will allow the new putty to stick securely.
After the frame has been cleaned and the rabbet prepared, it's the time to get ready for the replacement of the damaged pane. Order a piece of double strength glass that is 1/8 inch smaller in both directions. You'll also need to purchase glass points, which are metal triangles which help to hold the glass in place.
With the window sash taken off and the pry-bar flat, use it to gently pry the sash away from the moulding of wood. It is possible to scrape old glazing putty off using a utility blade or chisel. Then you can use the heat gun to warm any putty that doesn't be removed. This will make it easier to remove it.
When the frame is out from the molding then carefully press the new glass into the frame. Then, using a glazier's or putty knife's point, fill the gaps around it and smooth the edges. Once the putty has dried paint it in a manner that matches the rest of the frame. Paint it slightly over the edge of the compound, then 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 shards. Tape the window's edge to stop it from breaking when you take it off.
Make use of a utility knife to remove the old glazing compound from the wood frame and glazing points (small triangles of metal). Then, clean the frame opening and apply a coat of linseed oil to make the new stick of putty to it better.
Once the frame is in place to be measured, you can measure it for the new window pane. Then purchase it from a local home improvement store or other retailer. Choose the panes 1/6th inch smaller in each direction than your measurement. This will ensure a snug fit.
Installing the new window is simpler than you think, however make sure you follow the instructions of the manufacturer to ensure a correct fit and a long-lasting life for your replacement pane. Make use of a wirebrush to clean any paint or wood gunk from the frame's opening. Then sand the wood to the bare wood in order to improve the seal.
When you're putting the new pane in place, use the point of your putty knife and gently place the window on the frame made of wood. Put glazier's tips in the frame every six inches. This will hold the new pane securely in place.
Once the frame is cured then paint the new joint several times until it matches the frame. Let the paint dry completely before proceeding to cleaning and maintaining your window. Maintaining your windows in good shape and ensuring they function correctly will extend their lifespan and improve the energy efficiency of your home.
