Can Double Glazed Windows Be Repaired?

If you've recently had double glazing installed in your home and are beginning to show signs of failing you may be wondering if they can be repaired.

Broken Panes

When a window pane is damaged or cracked, air can pass through more easily. This reduces the effectiveness of the window as an insulation barrier and also against the elements. Depending on the season, this can cause hot or cold air to escape or enter your home, which can increase heating and cooling costs.

If the crack is not too deep, you may be able to apply a strong-hold adhesive tape. This is a temporary solution however, and could only stop the crack from growing. A professional window repair service can repair any broken glass that has been smashed on your double-glazed windows.

It could be risky and difficult to replace windows on your own. If the crack is too big to grasp then try pressing strips of masking tape in a crisscross pattern before trying to remove it. If the crack isn't too large you can make use of a razor to remove the glass from the frame. Wear gloves and a mask when cutting the glass. Once the pane is free, you will need to place it flat on a few layers of newspaper to catch any pieces that may fall.

To install a replacement glass, you'll need to prepare the frame and purchase replacement glass. To ensure that the new glass is a good fit take a measurement of the opening of the window frame and subtract between 1/16 and 1/8 inch on both sides. Cut your replacement glass at a local hardware or glass shop to this measurement. If you have wooden frames, you can purchase glaziers points from a hardware shop to install on the edges of your new pane. Be sure to install the points in a position that allows for expansion and contraction while still keeping the putty in a flat position against the glass.

Once your new pane is in place, spread an even layer of your chosen glazing compound with the help of a putty knife. Make use of a linseed-oil-based glue like Sarco or a less expensive product such as Dap glazing compound. If you notice any gaps between your new pane and the frame you can fill them in with your chosen compound. Smooth the compound on your new pane to make sure it is level and even.

Water Leaks

Water leaks around windows' frame or sash are a common issue. This occurs when the sealant on windows has worn out and needs to be replaced. Water leaks in the window could damage the drywall or plaster and can cause damp walls.

A double-glazed window of good quality has a gasket that is firmly compressed when the sash is closed. Any water that gets into this area must be drained out through the weep holes in the bottom of the frame. However, sometimes the weep holes become blocked by a build-up of dirt and debris or the weather stripping around the window might need to be replaced.

The lintel that is above the window can be a source of leaks. The installers who built the home may not have been aware that this lintel must be allowed to drain properly, or they could have just covered it with concrete, leaving gaps that allow rainwater to be able to enter and collect around the window, causing dampness in the wall or rot in the wood. The builders may have angled fascia boards above the windows to ensure water is directed correctly. This will stop water entering the building.


A gap between the glass panes of a double-glazed window can also be the cause of leaks. It is possible that gas argon or krypton that should be positioned between the glass panes to provide insulation has escaped out of the windows because of a worn out seal. While this isn't the most serious leaky window problem, it will impact on efficiency and should be taken care of as soon as is possible.

These droplets will rapidly disappear when the window is heated by sunlight. If the issue persists, it is worth looking further.

If this happens it is possible that simple fixes will aid, but in most cases, the best solution is to replace the window.

A spacer bar is usually found between the two glass panes that are found in the majority of double-glazed windows. The spacer bar is filled with desiccant that absorbs any moisture that might occur, thus stopping it from getting to the glass panes, causing condensation. However, this spacer bar can crack or break and in this instance, it is often required to replace the entire window.
