Can Double Glazed Windows Be Repaired?

If you've recently had double glazing installed in your home and they're beginning to show signs of failure, you may be wondering if they could be repaired.

Depending on what the problem is and the date you purchased them, you may be able to get your double-glazed windows replaced under warranty.

Broken Panes

If a window's glass is cracked or broken, it allows air to move more easily, which reduces the effectiveness of windows as insulation and barrier against the elements. Depending on the season, this can cause hot or cold air to enter or escape your home, causing an increase in the cost of cooling and heating.

If the crack in your double glazing is not too deep, it might be possible to just apply a strong-hold tape. This is only a temporary solution however, and it may only prevent the crack from getting worse. A reputable window repair service can fix any damaged glass on your double-glazed windows.

Attempting to replace a broken window pane by yourself can be tricky and dangerous. If the crack is too large to grasp and hold, try putting strips of masking tape across it in a crisscross pattern before trying to take it off. If the crack is not too large it is possible to employ a slicing tool to remove the glass from the frame. Make sure you wear gloves and a face mask when cutting glass. After the pane has been cut, you will need to lay it flat on several layers of newspaper to stop any pieces that might fall.

In order to install a replacement pane you'll need to prepare the frame and buy replacement glass. To ensure that the new pane fits properly, measure the opening of the window frame and subtract between 1/16 and 1/8 inch on both sides. Get your replacement glass cut at a local hardware store or glass shop to this measurement. If you have wooden frames, buy some points for glaziers from a hardware store to install on the edges of your new pane. Position the points so that they allow expansion and contraction while keeping the putty flush with the glass.

After your new pane is set and you are happy with it, apply a thick layer of your chosen glazing compound with a putty knife. Make use of a linseed oil-based putty such as Sarco or a less expensive product such as Dap glazing compound. Fill in any gaps between the frame and the new pane using the appropriate compound. Make sure you smooth the compound so that it is level and even all around your pane.

Water Leaks

The presence of water leaks around the frame or sash is a common issue that happens when window sealant has deteriorated and needs to be replaced. Water leaks can cause damage to the drywall and timber plaster surrounding the window, and can result in damp or spongy walls that require to be restored as quickly as is possible.

A double-glazed window that is of good quality has a gasket that is firmly compressed when the sash is closed. The water that enters the area should be drained out through the weepholes of the frame. However, sometimes the weep holes get blocked by a build-up of debris and dirt or the weather stripping around the window replacement might need to be replaced.

Another potential culprit of water leaks is the lintel which is a support for the brick that is over the window. The installers who built the home may not have been aware that this lintel should be let to drain properly or they may have simply covered it with concrete, leaving gaps that allow rainwater to enter and pool around the window, creating dampness in the wall or rot in the wood. The builders may have bent fascia boards over the windows to ensure that water is directed correctly. This will stop water getting into the building.

A gap between the glass panes of a double-glazed window can also be a source of leaks. It is possible that argon or krypton gas that is supposed to be in between the glass panes to provide insulation has leaked out from the windows due to the seal being worn out.

Certain IGUs also contain a gas, such as Argon that helps to prevent heat from leaving your home, thereby saving you on energy costs.

If one of the IGUs has been damaged, it is possible to replace the pane purchased from a window maker and then fitted to the frame. This is usually less expensive than replacing the whole window and is cheaper for most households.
