Can Double Glazed Windows Be Repaired?

Broken Panes

If a window’s glass is damaged or cracked, it allows air to flow more easily, reducing the effectiveness of windows as insulation and protection against the elements. Depending on the time of year this could cause hot or cold air to escape or enter your home, causing an increase in heating and cooling costs.

To ensure the best results, a professional window repair company should be contacted to fix any damaged glass in double-glazed windows.

If the crack is small enough that you can hold it steady and use a blade to cut it away from the frame. Make sure to wear gloves and a face mask when cutting glass. After the glass has been removed and laid flat, you can place it on several layers of newspaper to catch any fragments that might fall.

To install a replacement glass it is necessary to prepare the frame and buy replacement glass. Measure the opening of the frame and subtract 1/16 – 1/8 inch in both directions to ensure that the new pane is a good fit. Have your replacement glass cut at a local hardware or glass shop to this measurement. If you have wooden frames, purchase points for glaziers from hardware stores to put around the edges of your new pane. Be sure to install the points in a position that allows expansion and contraction while still keeping the putty level against the glass.

After the new pane is set, spread a thick layer of your glazing compound using the help of a putty knife. Use a linseed-oil-based putty like Sarco or window repairs a cheaper 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. Make sure you smooth the compound to ensure that it is level and even all around your pane.

A good double glazed window will have a gasket that will firmly compress when the sash is shut. Any water that gets into this area must be drained away via the weep holes at the bottom of the frame. However, sometimes the weep holes get blocked by a build-up of dirt and debris, or the weather stripping around the window might require replacement.

Another potential culprit of water leaks is the lintel, which supports the brick above the window. The people who built the house may not have realized that this lintel should be let to drain properly or they could have just covered it with concrete, leaving a gap where rainwater can get in and build up around the window, causing dampness in the wall or wood rot. The builders may have an angled fascia board above the windows to ensure water is directed correctly. This will stop water from getting into the building.

Another possible source of leaks is the gap between the glass panes in double-glazed units. It’s possible that the gas argon or Krypton that is supposed to be in between the glass to create insulation has escaped of the windows because of a worn out seal. While this isn’t the most serious issue associated with windows that leak but it could have a negative impact on energy efficiency. It should be addressed as soon as is possible. In this situation, replacement double glazing may be the best option. A professional will conduct an extensive evaluation, let you know the source of the leak from and suggest a solution.

These droplets will quickly evaporate when the window is heated by sunlight. However, if the issue persists, it’s worth looking further.

The majority of double-glazed windows have an “espacer” bar that is placed between the two glass panes. This spacer bar contains desiccant, which absorbs any moisture and blocks it from getting into the glass. This bar is susceptible to breaking or cracking and in most cases, you’ll need to replace your entire window.

The Insulated Glass Unit (IGU) is composed of two glass panes that have an opening in between and a rubber gasket that keeps water from leaking through the gap. Certain IGUs contain argon, a gas that prevents heat from escaping the home and saves you money on energy costs.
