Glazing Repair - How to Repair a Cracked Window

Glazing can make a huge impact on the energy efficiency of your home. This is especially important in older double-glazed windows.

While it is possible to replace the glazing points while the window is in position, it is quicker and easier if the glass and frame are removed. This is also a great occasion to replace the gaskets on the rubber.

Broken Glass

Broken glass isn't just unattractive, it can also let valuable sunlight and heat escape your home. It's usually possible to repair a damaged window without the need for a complete replacement.

Wear safety goggles and gloves. You should also place a piece of tape in an "X" shape on the glass you intend to remove (duct or painter's tape works well). This will stop any broken glass from falling onto your work surface as you work.

If you have a small scratch in your window glass you can cover it with tape to keep out the elements like wind, water and insects. If the crack is only superficial just a single strip of tape will be enough. However should the weather be expected to worsen before you can replace the window, you might need a more durable plastic cover, such as an tarp or trash bag.

For cracks that aren't as shallow, try using a strong adhesive specifically designed for windows, like Loctite Super Glue Glass. This high-tech adhesive is formulated to adhere to glass and dries crystal clear for the perfect finish. Apply it to the crack in the glass and let it dry completely before applying another layer.

Stress cracks are a different issue that can occur to your glass window. They're typically caused by dramatic changes in temperature, and they can quickly spread across the entire glass window if it's not fixed. To stop stress cracks from occurring create a small arc with glass cutters close to the crack. This will prevent the crack from expanding and reducing the severity for several days.

Examine the frame of the broken window to determine the size of the new pane. It should be slightly larger than the opening in order to allow for expansion and contraction and to account for any imperfections in the frame or on the glass. Once you've cut the glass to size apply glaziers' compounds around the edges of both the frame and the glass. Once the compound dries, paint over it to match the rest of the window frame.

Double Glazed Windows Condensation Inside

Condensation inside double-glazed windows is typically an indication that the seal on the window unit has failed. This is a major issue, as it can indicate that heat is lost from your home through the window.

Double glazing is designed to block heat transfer between two panes, by sandwiching an air or vacuum layer between them. This creates a seal that prevents warm air from venting. If the glass is warmer than the frame, condensation can develop on the glass and cause damage to the window. If you are unable solve condensation issues on a double-glazed window by opening windows, using extractors, using dehumidifiers or trickle venting, then you might require a professional.

Condensation on the exterior of double-glazed windows is not common however it can happen when the seal has started to weaken between the glass and the window frame. This is more prevalent in winter, when the temperature is lower, making it more easy for condensation to form. The primary reason for this is a flaw in the spacer that is used between the window and the frame. The spacer is filled with desiccant which is extremely absorbent and absorbs any moisture that is present.

This could result in moisture seeping through the gap when the desiccant has been saturated. This could lead to condensation and water leaking into the gap and is very difficult to get rid of.

Most reputable window companies provide a guarantee and will replace the glass and unit of a window in the event that it's damaged by condensation. It is essential to report any issues to your window installer as soon as you notice them so that condensation can be addressed as soon as possible to prevent further damage to the window unit as well as the frame surrounding it.

It is also recommended to wash the rabbet prior to proceeding, which is the part of the frame around the window frame, where glass will be. Apply a coat linseed to the rabbet and then wipe it down. This will help the putty to stick.

After the frame has been cleaned and the rabbet prepared, it's the time to plan the replacement of the broken pane. Get a piece made of double strength glass that is one inch smaller in both directions. You'll need to buy glass points which is a metallic triangle that holds the glass in place.

With the window sash out of the way, gently pry it off of the wood molding with a straight pry bar. You may have to scrape off old glazing using a utility knife or chisel. Make use of the heat gun to warm any putty that cannot be easily removed. This will make it easier to remove it.

Once the frame is free from the molding, carefully press the glass in the frame. Then, with a glazier's or putty knife's point, fill the gaps around it and smooth the edges. When the putty is dry, paint it to match the rest of the frame. Paint the glass and the compound by overlapping the paint slightly.

Replacement Window Glass

Wear eye protection and gloves when replacing a damaged pane of glass. Tape the window's edge to stop it from breaking once you remove it.

Use a utility blade to cut off the old glazing compound from the wood frame and glazing points (small triangles of metal). Clean the entire opening of the frame and then apply a coat of linseed to make sure the new glue sticks better.

Once the frame is ready to be measured, you can make sure you measure it to get the new window pane. Then purchase it from a local home improvement store or other retailer. The panes should be 1/6th inch smaller in each direction than your measurement. This will ensure a perfect fit.

Installing the new window is easier than you think, however be sure to follow the directions of the manufacturer to ensure the 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. then sand it down to bare wood to enhance the seal between the frame and sash.

Use the edge of the putty blade when installing the new window to lay it gently against the frame of wood. Then, press glazier's facets into the frame approximately every six inches to secure the window securely in place.


After the frame has cure, paint the new joint with several coats of paint to match the rest of the frame. Let the paint dry completely before moving on to cleaning and maintaining your window.
