Can Double Glazed Windows Be Repaired?

If you have recently had double glazing installed in your home and are beginning to show signs of failing, you might be wondering if they are able to be fixed.

You may be able get your double glazing repaired under warranty depending on the problem and the date when you bought it.

Broken Panes

If a window's glass is cracked or broken it allows air pass more easily, lowering the effectiveness of windows as insulation and protection against the elements. This could cause hot or cold air to enter your home, based on the time of year. The cost of cooling and heating will increase.

If the crack isn't too deep, you may be able to utilize a strong-hold adhesive tape. This is a temporary fix however, and it could only stop the crack from getting worse. To get the best results, a reputable window repair service is required to fix any damaged glass on your double-glazed windows.

It is risky and difficult to repair a window pane on your own. If the crack is too large to grasp then try pressing strips of masking tape in a crisscrossing pattern prior to trying to remove it. If the crack is small enough to be able to hold it steady and use a razor to remove it from the frame. Make sure you wear gloves and a face mask when cutting glass. After the glass has been removed then place it flat on many layers of newspaper to catch any pieces that might fall.

To install a replacement glass you'll need to prepare the frame and buy replacement glass. Find the opening of the frame and subtract 1/16 - 1/8 inch in both directions to make sure that your new pane will fit correctly. Cut your replacement glass at a local hardware store or glass shop to this measurement. If you have wooden frames, you can purchase points for glaziers from a hardware store to be positioned on the outside of your new glass. Make sure to place the points in a manner that will allow expansion and contraction while still keeping the putty in a flat position against the glass.

Once your new pane has been placed and you are happy with it, apply a thick layer of your chosen glazing compound with the help of a putty knife. You can use a linseed oil-based putting such as Sarco, or a cheaper product such as Dap glazing compound. Fill any gaps between the frame and the new pane with your chosen compound. Smooth the compound over your new pane to make sure it is level and even.

Water Leaks

Water leaks in a window's frame or sash are a typical issue. This occurs when the window sealant is damaged and requires replacement. Water leaks can cause damage to the plaster and drywall surrounding the window, and can lead to damp or moldy walls that need to be restored as quickly as possible.

A good quality double glazed window has a gasket that will firmly compress when the sash is shut. Any water that comes into the area should be drained away via the weep holes located in the bottom of the frame. However, sometimes the weep holes become blocked by a build-up debris and dirt or the weather stripping around the window could require replacement.

Another possible cause of water leaks is the lintel, which supports the brick above the window. The builders who constructed the house may not have understood the importance of allowing the lintel to drain properly, or have covered it with concrete, which left a gap in which rainwater could get in and then accumulate, creating dampness or rot on the wood. The builders could have placed an angled fascia board above the windows to ensure that water is directed properly. This will stop water from getting into the building.

A gap between the glass panes of a double-glazed windows could 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 from the windows due to a worn out seal. Although this isn't the most serious leaky window problem however, it could affect energy efficiency and should be dealt with as soon as it is possible. In this case replacement double glazing might be appropriate. A professional can conduct an extensive evaluation and let you know the source of the leak. They can also recommend solutions. They will be able to tell you whether it is advisable to fix the window or replace it completely. They will also provide an estimate for any work needed.

Condensation

Condensation is a very common problem in older double glazed windows and doors, but it can be easily solved. It is caused by the lack of air flow around windows and is common in areas like kitchens or bathrooms. Droplets of water on the surface of the glass are an obvious sign of condensation. The droplets will evaporate when the window is heated by sunlight. However, if the issue persists it is worth investigating further.

Another sign of condensation is if you can hear water dripping. This is usually because of a broken seal between the two glass panes. Repairs are highly recommended if there is this sound. This will stop cold drafts entering your home. This kind of issue could cause mould over time, so it is best to have the window repaired as soon as possible.
