Glazing Repair - How to Repair a Cracked Window
Glazing can make a significant difference to the energy efficiency of your home. This is particularly true for older double-glazed windows.
While it is possible to replace the glazing points when the window is still in place, it is much quicker and easier when the frame and glass are removed. It is a good time to replace the rubber seals.
Broken Glass
Glass that is cracked isn't just ugly, it can also let valuable heat and sunlight escape from your home. It is possible to repair damaged glass without replacing the entire window.
Wear safety glasses and gloves. Also, you should put an X-shaped piece of tape an "X" shape on the glass that you plan to remove (duct or painter's tape works well). This prevents any shattered pieces from falling when you work, which can keep you from serious injuries.
If you have a small crack in the glass of your window you can cover it with tape to block water, wind, and insects. One strip of tape should be sufficient for cracks with a superficial appearance but if you're worried about the weather getting worse before you can replace your window, consider using an extra-strong plastic cover like a tarp, or a garbage bag, to keep the glass in place until you can get a permanent fix.
For cracks that aren't quite as shallow try using a tough adhesive designed specifically for windows, like Loctite Super Glue Glass. This high-tech glue is made to attach to glass and then dry transparent to give a perfect finish. Apply it to the crack, and let it dry completely before applying another layer.
Glass windows may also develop stress cracks. They're typically caused by dramatic changes in temperature, [Redirect Only] and they can quickly spread across the entire glass window if it's not treated. To stop stress cracks from occurring create an arc of a tiny size with a glass cutter near the crack. This will stop the crack from spreading and may slow it down by a day or so.
If you're replacing a damaged window, measure the frame for the new pane. It should be slightly bigger than the opening to allow for expansion and contraction, as well as to make up for any imperfections that may occur on the frame or on the glass. After cutting your glass, apply glaziers compound around the edges of the frame and glass. Once the compound dries paint it over to match the frame of the window.
Condensation on the Inside of Double Glazed Windows
The appearance of condensation on the interior of double-glazed windows typically indicates that the seal has been damaged at some point along the window unit. This is a major issue because it could indicate that heat is lost from your home through the window.
New double glazing is designed to prevent heat transfer between two glass panes by sandwiching a layer of air or vacuum between them. This creates a tight seal that blocks warm air from escaping. However, if the glass is cold or colder than the frame, condensation will accumulate on it, which can damage the window. If you notice condensation on your double glazed window and you are unable to resolve it by opening the windows by using extractor fans, dehumidifiers or trickle venting then you may require the help of a professional.
It's much rarer for condensation to appear on the exterior of double-glazed windows, but it could occur if the seal between the glass and the window frame is beginning to break down. This is more frequent in winter as the temperatures are lower and it's more easy for fitters condensation to develop. This is due to a defect in the spacer that is used between the frame and the window. The spacer is filled with desiccant which is very absorbent and will absorb any moisture that is present.
The issue with this is that when the desiccant becomes saturated it will begin to break down, and eventually moisture will begin to seep through the gap between the glass units. This could lead to condensation and water in the gap, and can be very difficult to eliminate.
The good news is that the majority of trustworthy window manufacturers will provide warranties on their products. They should replace the window unit and glass if it has been damaged by condensation. It's essential to notify your window installer when you spot them so that condensation can be addressed promptly in order to prevent further damage to the window repair unit as well as the surrounding frame.
Shattering Window Glass
A cracked window pane is more than an aesthetic issue. It can also pose the risk of injury, particularly when it's causing. It's best to get it repaired as quickly as possible. There are many ways to do it, including using glass adhesives made for windows of vehicles and can be bought online or at many auto repair shops. Alternately, you can make use of a glass compound designed for home use, which can be found at a variety of hardware or home improvement stores.
Put on thick gloves and safety glasses before you begin any work. Sweep the area to get rid of any large shards. You should also vacuum up any chips that have fallen. This will prevent them from cutting you or a glass repair professional in the future.
It is a good idea to climb a ladder instead of standing on the floor. This will allow you to reach all the parts of the frame more easily and also protect your glass from falling. It's also a good idea to clean the rabbet before proceeding with the installation. This is the area around the perimeter of the window frame that is where the glass will go. Apply a coat of linseed to the rabbet and then wipe it down. This will aid in helping the putty adhere.
After the frame has been cleaned and the rabbet ready, it's time to get ready for the replacement of the broken pane. Find the height and width of the opening both ways and then purchase the double-strength piece of glass that is 1/8 inch shorter in both directions. You'll also need glass points, which are steel triangles that hold the glass in the right place.
With the window sash removed from the way, carefully pry it off of the wood molding using an angled pry bar. You may need to scrape off old glazing putty with a knife or chisel. Then, use the heat gun to warm up any putty that isn't able to come off. This will make it easier to peel it off.
Once the frame has been free from the molding then carefully press the glass in its place. Then, with the help of a putty knife or glazier's point, fill in 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

Make use of a utility knife to remove the old glazing compound from the frame and glazing points (small triangles of metal). Then, clean the frame opening and apply a layer of linseed oil to help the new putty stick to it better.
Once the frame has been constructed, take measurements to determine the dimensions of the new windowpane. Then, you can purchase it at a home improvement store or other retailer. Order the panes 1/6th inch smaller in each direction than you measurement. This will ensure a perfect fit.
It's easier than you think to put in a new window. However, it is crucial to follow the directions given by the manufacturer to ensure a proper fit and long-lasting replacement pane. Use a wire brush to clean the frame of old paint or wood gunk and then sand it to bare wood, which will improve the seal between the frame and the sash.
When you are putting the new window in place, use the point of your putty knife to lightly bed the new window against the frame of wood. Put glazier's tips in the frame every six inches. This will hold the new pane securely in position.
When the frame is cure, you can coat the joint with a few coats of paint that match the rest of the frame. Let the paint dry completely before proceeding to cleaning and maintaining your window.
