Can Double Glazed Windows Be Repaired?

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

You might be able to get your double glazing under warranty based on the issue and when you bought it.

Broken Panes

If a window pane becomes cracked or broken, it allows air to move more easily, which reduces the windows' effectiveness as an insulation and double glazing barrier against the elements. Based on the season, this can cause warm or cold air to escape or enter your home, which can increase heating and cooling costs.

If the crack is not too deep, you may be able to utilize a strong-hold adhesive tape. This is temporary fix, and will only stop the crack from getting more severe. A professional window repair service can fix any broken glass that has been smashed on your double-glazed windows.

Attempting to replace a broken window pane by yourself can be difficult and risky. If the crack is too large to grasp, try pressing strips of masking tape across it in a crisscrossing pattern prior to trying to take it off. If the crack is small enough, you can hold it in place and use a blade to cut it off from the frame. Make sure you wear gloves and a face mask when cutting glass. After the glass has been removed, place it flat onto several layers of newspaper to catch any fragments that might fall.

In order to install a replacement pane, you'll need to prepare the frame and purchase replacement glass. To ensure that the new pane is properly fitted, measure the opening of the frame and subtract between 1/16 and 1/8 inches on both sides. Then, have the replacement glass cut to this measurement at a local glass shop or hardware store. If you have wooden frames, purchase glaziers' points at hardware stores to put on the edges of your new pane. Be sure to position the points in a way that allows expansion and contraction, while keeping the putty level against the glass.

After the new pane has been placed then spread an even layer of your preferred glazing compound with the help of a putty knife. Use a linseed-oil-based putty like Sarco or a lesser-priced product such as Dap glazing compound. Fill in any gaps between the frame and pane using the compound you choose. 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 typical issue that can occur when window sealant has deteriorated and requires replacement. Water leaks around the window can damage the plaster or drywall and can cause damp walls.

A good quality double glazed window has a gasket that is able to compress when the sash is shut. Any water that gets into this area should be drained out through the weep holes located in the bottom of the frame. However, sometimes the weep holes become blocked by a build-up dirt and debris, double glazing or the weather stripping around the window might need to be replaced.

Another possible cause of water leaks is the lintel which supports the brick above the window. Installers who built the house may not have been aware of the importance of allowing the lintel to drain properly, or have covered it with concrete, which left a gap in which rainwater can enter and get trapped, causing dampness or rot on the wood. The builders should have bent the fascia boards over the window to ensure that the water is directed properly and this will stop water from entering the building through these gaps.

Another possible leak source is the gap between the glass panes of double-glazed units. It is possible that gas argon or krypton that is supposed to be in between the glass to provide insulation has escaped out from the windows due to the seal being worn out. Although this isn't the most serious issue with leaky windows, it will affect energy efficiency. It is important to address the issue in the shortest time possible. In this situation double glazing replacement might be necessary. A professional will conduct an extensive evaluation, let you know the source of the leak from and recommend solutions. They can also tell you if it is better to fix or replace the window. They can also provide an estimate for any work that is needed.

Condensation

Condensation is a frequent problem in older double glazed doors and windows, but it can be easily corrected. This is due to the lack of air circulation around the window, and typically happens in rooms such as bathrooms or kitchens. Droplets of water on the glass surface of the glass are a clear sign of condensation. These droplets will evaporate quickly when the window is heated up by sunlight. If the problem continues it's worth investigating further.

Another indicator of condensation is when you hear water drips. This is most likely due to a broken seal between the two glass panes. Repairs are highly recommended if you hear this sound. This will stop cold drafts from entering your home. This kind of issue could cause mould over time, so it's recommended to have the window repaired promptly.

Having a professional examine your window for condensation is the best way of dealing with this issue, as they will be able to recommend the correct method of action. Professional firms will remove the affected glass and then blow hot air between the two panes. This will dry out any remaining moisture and ensure that a high-quality seal is applied.

Failing windowpane seals are the main cause of condensation issues with double glazing. If the window seal is damaged, it allows cool air into double-paned windows, which makes them fog. If this happens it's possible that simple fixes will aid, but in most instances, the best option is to replace the window.

A spacer bar is typically found between the two glass panes of most double-glazed windows. The spacer bar is stuffed with desiccant that absorbs any moisture that may occur, thus preventing it from reaching the glass panes and causing condensation. Unfortunately, this spacer bar can sometimes break or crack and in this situation, it is typically necessary to replace the entire window.

It is possible to complete some repairs yourself if have the appropriate tools, but it is normally better to hire an expert who is trained to do this for you. This will not only save you a huge amount of time, it will also ensure that your double glazing is repaired properly and of the highest quality. A reliable tradesperson can also mean you receive some form of guarantee for the work that is completed that you would not get from a DIY job.

Shattering

Double glazing is a fantastic technology that lets homeowners save money on heating bills, whilst keeping their homes warm and comfortable. It isn't impervious to damage and problems can arise from time to time. These flaws could be dangerous in some cases if they are not corrected promptly.

As such, if you have noticed any problems with your double glazing that could put your family at risk, then it's important to fix them in the earliest time possible. Faults like misting and water leaks can compromise the effectiveness of windows and cause them to look unsightly.

Repairing double-glazed windows is usually cheaper than replacing them. If you notice any signs of trouble in your double glazing, it's worthwhile to research local companies that specialize in double glazed upvc window repairs repairs and getting estimates. The most affordable quote might not be the best option. Be sure that the company you choose has a guarantee with their work.

Double-glazed windows are sold as an Insulated Glass unit (IGU). The Insulated Glass Unit (IGU) is made up of two glass panes, with an area between them, and a rubber gasket which keeps water from leaking through the gap. Certain IGUs also contain a gas such as argon that helps to keep heat from escaping your home, therefore cutting down on energy costs.

If one of the IGUs is damaged a replacement pane can be purchased from a window manufacturer and then fitted to the frame. This is typically less expensive than replacing the entire window and is more cost-effective for a lot of households.

Depending on the kind of window you have and the condition of the frame, it might be possible to repair the damaged pane. This is typically the case when it has just developed a few minor cracks, but has not shattered. If your double glazed window has completely broken, then it's probably best to replace the entire glass unit and the window sash.
