Can Double Glazed Windows Be Repaired?

If you've recently installed double glazing in your house, and it is beginning to begin to show signs of failing, you may wonder whether they could be repaired.

You may be able to claim your double glazing covered under warranty based on the issue and the date you purchased it.

Broken Panes

If a window's pane is cracked or broken, air can pass through more easily. This reduces the effectiveness of the window as an insulation and protects against the elements. Based on the season it can allow hot or cold air to flow into or out of your home, causing an increase in heating and cooling costs.

If the crack in your double glazing isn't too deep, it might be possible to just apply a strong-hold tape. This is a temporary solution however, and could only stop the crack from growing. To get the best results, a reputable window repair service is required to fix any broken glass in your double glazed windows.

Removing a damaged window pane by yourself can be tricky and dangerous. If the crack is too big to grasp, try pressing strips of masking tape across it in a crisscross pattern before trying to remove it. If the crack is small enough to be able to hold it in place and use a razor blade to cut it away from the frame. Make sure you wear gloves and a face mask when cutting glass. Once the glass is removed and laid flat, you can place it on many layers of newspaper to catch any pieces that may fall.

In order to install a replacement pane it is necessary 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 inches on both sides. Then, have the replacement glass cut to this measurement at your local glass shop or hardware store. If you have wooden frames, buy glaziers points from a hardware store to place them along the edge of your new glass. Place the points in a way that they allow expansion and contraction while keeping the putty flush with the glass.

Spread a thick layer with the blade of a putty maker after your new pane is installed. 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, fill them in with the compound you choose. Smooth the compound on your new pane to ensure it is even and level.

Water Leaks

The presence of water leaks around the frame or sash is a frequent issue that can occur when window sealant has become degraded and requires replacement. Water leaks around the window can cause damage to the drywall or plaster and lead to damp walls.

A double-glazed window that is of good quality will have a gasket which compresses firmly when the sash is closed. Any water that comes into this area must be drained away through the weep holes at the bottom of the frame. Sometimes, however, the weep holes become blocked by a build-up dirt and debris or the weather stripping around the window might require replacement.

The lintel above the window could also be an area of leaks. The builders who constructed the house might not have been aware of the importance of allowing the lintel to drain properly, or have clad it in concrete, leaving a gap through which rainwater could enter and accumulate, causing dampness or rot on the wood. The installers should have bent the fascia boards over the window to ensure that water is directed properly. This will stop water from entering the building through these gaps.

Another possible source of leaks is the gap that exists between the glass panes of double-glazed units. A worn seal could have caused the gas argon or krypton that is supposed to be between the glass panes to provide insulation to leak out. Although this is not the most serious issue associated with leaky windows however, it could have an impact on energy efficiency. It should be addressed as soon as is possible. In this situation double glazing replacement could be required. A professional can conduct a full evaluation, let you know the source of the leak from and suggest a solution. They can also tell you if it is better to replace or repair the window. They will also be able to provide you a quote for any work that is required.
