Broken Glass
Broken glass isn't just unattractive but can also let valuable heat and sunlight escape from your home. It is possible to repair a broken pane of glass without having to replace the entire window.
Begin by putting on protective gloves and safety goggles. You should also place an X-shaped piece of tape an "X" shape on the glass you plan to remove (duct or painter's tape work well). This will prevent any broken pieces from falling as you work, which can protect you from serious injury.
If you have a small scratch in your window glass you can cover it with tape to keep out rain, wind, and insects. One strip of tape should be enough for superficial cracks however if you're concerned about the weather becoming worse before you can replace your window, consider using a more durable plastic cover like a tarp or trash bag, to hold the glass in place until you get a permanent fix.
Use an adhesive that is strong and specifically designed for windows to fix cracks. Loctite Super Glue Glass is a good option. This high-tech glue is designed to bond to glass and dries clear for a flawless finish. Apply it to the crack in the glass and let it dry completely before applying a second layer.
Stress cracks are another common problem that can happen to your glass window. Stress cracks are usually caused by drastic temperature changes and can rapidly spread across the entire window if not addressed. To stop stress cracks from occurring, score an arc using glass cutters near the crack. This will stop the crack from spreading and may slow it down by a day or two.
If you're replacing a broken 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 the glass to the proper size apply glaziers' compounds around the edges of both the frame and the glass. After the compound has dried paint it in a manner that matches the frame.
Condensation inside of Double Glazed Windows
The appearance of condensation on the interior of double glazed windows usually indicates that the seal has been damaged somewhere along the window unit. This is a serious issue because it indicates that heat from your home is being lost through the window and could be costly for you and your energy bills.
Double glazing is designed to stop heat transfer between two panes, by sandwiching an air or vacuum layer between them. This creates an airtight seal that stops warm air from escaping the home. However, if the glass is colder or colder than the surrounding frame, then condensation can form on it, which can damage the window. If you are unable to resolve condensation on a double-glazed window by opening windows or using extractors, dehumidifiers or trickle venting, you might require professional help.
Condensation on the exterior of double-glazed windows is uncommon, but it can occur if the seal has begun to break down between the glass and the window frame. This is more common in winter when the temperature is lower, making it more likely for condensation to form. This is caused by an issue in the spacer used between the frame and the window. The spacer usually contains desiccant that is extremely absorbent and can absorb excess moisture.
The issue with this is that once the desiccant is saturated, it will start to break down and water can begin to enter the gap between the glass units. This can cause condensation and water to build up in the gap, which is difficult to remove.
Most reputable window companies offer a warranty and will replace the unit and glass of a window in the event that it's damaged by condensation. Inform any issues as quickly as you can to the window manufacturer so that the condensation is repaired as quickly as it can to avoid further damage.
Shattering Window Glass
A damaged or cracked window can be more than just an aesthetic problem. It could also pose an injury risk, particularly if it is spreading. It is best to get it repaired as quickly as you can. You can use glass adhesives for windows in vehicles which you can purchase on the internet or in many auto repair shops. You can also use a glazing compound for use at home that is available at most hardware and home improvement stores.
Before beginning any work, put on thick protective gloves and safety glasses and sweep the area to get rid of large shards. You'll also want to vacuum up any chips that have fallen. This will prevent them from causing injury to you or a glazing repair technician later on.
It's a good idea climb a ladder instead of laying on the floor. This will allow you to reach all the areas of the frame and ensure that you are safe from falling glass. Before you start, it's a good idea clean the rabbet. This is the area where glass is placed. Clean it off and then apply a coat of linseed oil to the rabbet, which will help the new putty stick in place.
After the frame has been cleaned and the rabbet is ready, it's time to plan the replacement of the damaged pane. Purchase a piece of double strength glass that is 1/8 inch smaller in both directions. Also, you'll need to purchase glass points, which are metal triangles that keep the glass in place.
With the window sash off the way, carefully pry it off of the wood molding using an angled pry bar. You may have to scrape old glazing putty off using a utility knife or chisel. Make use of the heat gun to warm any putty which isn't able to be removed easily. This will make it easier to peel off.
When the frame is out of the mold, carefully press the glass in its place. Fill in the gaps using the glazier's tip or a putty knife. After the putty has dried paint the frame to match. Lap the paint 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 protect yourself from glass shatters. Tape off the area around the broken window to prevent it from shattering again in a different location when you take it off.
Start by removing the old glaze compound and glazing points (small metal triangles) from the frame using a knife. Clean the frame opening, and then apply a coat of linseed to make sure the new glue sticks better.
When the frame is complete and you are ready to measure it for the new window pane. Then purchase it from a home improvement store or other retailer. Be sure to purchase the pane one-sixth inch shorter in each direction than your measurement to ensure an ideal fit.
Installing the new window is easier than you think, but make sure you follow the manufacturer's directions to ensure a right fit and long-lasting life for your replacement pane. Use a wire brush to clear the frame opening of any old paint or wood gunk and then sand it down to bare wood to enhance the seal between the frame and the sash.
Use the edge of the putty blade when putting in the new pane to lightly place it against the frame of wood. Then, press glazier's facets into the frame approximately every six inches to hold the new window firmly in place.
After the frame has cured, paint the new joint several times until it matches the frame. Let the paint completely dry before proceeding to cleaning and maintaining your window. Maintaining your windows in good condition and operating correctly will prolong their useful lifespan and increase the efficiency of your home's energy usage. If your windows are outdated or not in great shape then you might be better off with replacing your windows completely. If you opt for this option, we recommend choosing a high-quality, insulated window to lower your energy costs. The type of window you select will also affect the total cost of your project.
