Can Double Glazed Windows Be Repaired?
If you have recently had double glazing installed in your home and they're beginning to show signs of failing, you may be wondering if they could be fixed.
Depending on what the issue is and when you purchased them, you may be able to get your double-glazed windows replaced under warranty.
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 against the elements. Depending on the time of year it can allow hot or cold air to escape or enter your home, causing an increase in heating and cooling costs.
If the crack isn't too deep, you might be able to use a strong-hold adhesive tape. This is only a temporary solution however, and it could only stop the crack from growing. To ensure the best results, a reputable window repair service is required to fix any broken glass on your double-glazed windows.
The process of replacing a damaged window pane yourself is difficult and risky. If the crack is too large to grasp then try pressing strips of masking tape across it in a crisscrossing pattern prior to trying to remove it. If the crack is small enough to be able to hold it in place and use a blade to remove it from the frame. Wear gloves and a mask while cutting the glass. Once the pane is free you must place it flat on several layers of newspaper to catch any pieces that may fall.
To install a new glass pane, you will need to purchase replacement glass and then prepare the frame. Take measurements of the opening of the frame and subtract 1/16 to 1/8 inch in both directions to ensure that your new pane will fit properly. Then, you can have your replacement glass cut according to this measurement at a local glass shop or hardware store. If you have wood frames, buy some points for glaziers at hardware stores to put around the edges of your new pane. Be sure to install the points in a way that allows for expansion and contraction, while keeping the putty flat against the glass.
Spread a thick layer of it with a putty knife after your new pane is installed. You can make use of a linseed oil-based glue such as Sarco or a lesser product like Dap glazing compound. If you have any gaps between your new pane and the frame then fill them in using your chosen compound. Make sure you smooth the compound to ensure it is level and even all around your pane.
Water Leaks
The presence of water leaks around the frame or sash is a frequent issue that happens when the window sealant has degraded and requires replacement. Water leaks around the window can cause damage to the plaster or drywall and cause damp walls.
A double-glazed window of good quality will have a gasket which compresses firmly when the sash closes. Any water that hits the area should be drained away via the weep holes in the bottom of the frame. However, in some cases, the weep holes get blocked by a build-up of debris and dirt or the weather stripping around the window might need to be replaced.
The lintel that is above the window could also be a source of leaks. The builders who constructed the house may not have understood the importance of allowing the lintel to drain properly, or they could have clad it in concrete, which left a gap in which rainwater can enter and get trapped, causing dampness or rot on the wood. The installers could have angled fascia boards above the windows to ensure water is directed correctly. This will prevent water entering the building.
Another potential leak source is the gap between the glass panes in double-glazed units. A worn seal could have caused gas argon or krypton that is supposed to be in between the glass panes to create insulation to leak out. Although this isn't the most severe leaky window issue, it will impact on efficiency and must be taken care of as soon as is possible. In this case replacement double glazing might be appropriate. A professional can complete an extensive evaluation, let you know where the leak is coming from and suggest solutions.

Condensation
Condensation is a frequent problem in older double glazed doors and windows, but it is usually easily fixed. This is caused by the lack of air circulation around the window and often is seen in rooms like kitchens or bathrooms. The most evident indication of condensation is droplets of water appearing on the glass surface. These droplets will disappear quickly when the window is heated up by sunlight. If the issue persists it is worth investigating further.
It is also possible to hear the sound of water drip. This is likely because of a damaged seal between the two panes of glass. Repairs are highly recommended if you hear this noise. This will stop cold drafts from entering your home. This kind of issue can also lead to mold in the long run, so it is best to have the window repaired as soon as possible.
A professional inspection of your window for condensation is the most efficient approach to tackling this problem, as they will be able to recommend the correct course of action. Most professional companies will remove the affected pane, and then pipe hot air into the gap between them, this will dry out any moisture that remains and ensure a good seal is reapplied.
The windowpane seals failing are the primary cause of condensation issues with double glazing. When the window seal fails it allows cool air into double-paned glass windows, making them to fog. Simple fixes may help, but often the most effective solution is to replace the windows.
A spacer bar is usually found between the two glass panes of most double-glazed windows. The spacer bar is stuffed with desiccant, which absorbs any moisture that might occur, thus keeping it out of the glass panes, causing condensation. However, this spacer bar may break or crack, and in this case it is typically necessary to replace the entire window.
It is possible to do repairs yourself if you have the appropriate tools, however it is generally better to employ an expert who is trained to do this for you. You will save a lot of time and ensure that the double-glazing is repaired correctly. A reliable tradesperson can also mean that you get some kind of assurance for the work that is completed which you wouldn't get with a DIY job.
Shattering
Double glazing is an innovative product that allows homeowners to reduce heating costs while keeping their homes warm. But it's not impervious to damage and, from time to time, problems can occur. In some instances the faults could be dangerous if not addressed promptly enough.
If you spot any issues with your double-glazing, which could put your family members in danger, it's important to fix them as quickly as you can. Faults such as misting and leaks of water can affect the performance of windows and also leave them looking unsightly.
It is often far cheaper to repair your double glazed windows than to replace them completely. So, if you have noticed any signs of problems with your double glazing, it's worth researching local companies that specialise in repairs for double glazed windows and asking for estimates. Be aware that the lowest price isn't always the most effective and ensure that your chosen firm offers a guarantee on their work.
When a double glazed window is sold in the market, it will be housed within an Insulated Glass Unit (IGU). The Insulated Glass Unit (IGU) is made up of two glass panes with an opening in between and a rubber gasket which stops water from entering the gap. Certain IGUs contain the gas argon. It stops heat from escaping the house and helps save money on energy costs.
If one of the IGUs is damaged it is possible to replace the pane purchased from a window manufacturer and fitted to the frame. This is usually less expensive than replacing the entire window and is cost-effective for a lot of households.
It could be possible to repair the damaged window dependent on the frame type and condition of your window. If the glass has developed just a few tiny chips, but not been shattered, this is usually the case. If the double-glazed window has totally broken, it's recommended to replace both the glass unit and the window sash.
