Can Double Glazed Windows Be Repaired?

If you recently installed double glazing in your home and it is beginning to begin to show signs of failing, you might be wondering whether they could be repaired.

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 pass more easily, lowering the windows' effectiveness as an insulation and barrier against the elements. This can allow cold or hot air to enter your home based on the time of year. The cost of cooling and heating will rise.

If the crack isn't too deep, you might be able to use a strong-hold adhesive tape. This is a temporary fix, though, and it may only prevent the crack from becoming worse. A professional window repair service can fix any broken glass on double-glazed windows.

It can be dangerous and difficult to repair a window pane on your own. If the crack is too big to grasp and hold, try putting strips of masking tape in a crisscrossing fashion prior to trying to remove it. If the crack isn't too large to be able to hold it steady and use a blade to cut it off from the frame. Make sure to wear gloves and a mask when cutting glass. Once the glass is removed then place it flat on several layers of newspapers to catch any fragments that might fall.

To install a new pane you'll need to purchase replacement glass and set up the frame. Measure the opening of the frame and subtract 1/16 to 1/8 inch in both directions to ensure that your new pane is a good fit. Get your replacement glass cut at a local hardware or glass shop to this measurement. If you have wooden frames, buy points for glaziers from a local hardware store to place them on the edges of your new pane. Make sure to place the points in a way that will allow expansion and contraction while keeping the putty level against the glass.

Once your new pane is in place then spread an even layer of your preferred glazing compound with a putty knife. Make use of a linseed-oil-based glue like Sarco or a less expensive product such as Dap glazing compound. Fill in any gaps between the frame and pane using the appropriate compound. Smooth the compound around the new pane to ensure it is level and even.

Water Leaks

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

A double-glazed window that is of good quality will come with a gasket that expands with force when the sash is closed. The water that is absorbed by this area should be drained through the weepholes in the frame. Sometimes, however, the weep holes get blocked by a build-up debris and dirt or the weather stripping around the window may need to be replaced.

Another possible cause of water leaks is the lintel which is a support for the brick that is 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 in concrete, which left a gap in which rainwater can enter and get trapped, creating dampness or rot on the wood. The builders could have placed angled fascia boards above the windows to ensure water is directed correctly. This will stop water entering 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 between the glass to provide insulation has escaped out of the windows due to an old seal. Although this isn't a particularly serious issue with leaky windows however, it could affect energy efficiency and should be dealt with as soon as it is possible. In this instance replacing double glazing could be appropriate. A professional can conduct an exhaustive evaluation, letting you know where the leak is coming from and recommend solutions. They will also be able to advise whether it makes sense to fix the window or replace it completely. They will also provide an estimate for any work needed.

Condensation

Condensation may be a problem with older double-glazed windows and doors. However, it's generally an easy fix. It is caused by the lack of air flow around the windows and occurs in areas like kitchens or bathrooms. Droplets of water on the glass surface of the glass are an obvious sign of condensation. The droplets will quickly evaporate when the window is heated up by sunlight. If the problem persists, it's worth looking into further.

You can also hear the sound of water drip. This is likely due to a damaged seal between the two glass panes. Repairs are highly recommended if you hear this sound. This will stop cold drafts entering your home. This type of issue can cause mould over time, so it is best to get the window repaired promptly.

A professional inspection of your window for condensation is the best method of tackling this issue, since they will be able to recommend the correct course of action. The majority of professional companies will take off the affected window and pipe hot air into the gap between the two, this will dry out any moisture that remains and ensure a good seal is reapplied.

Double glazing condensation is caused by windowpane seals. If the window repairs seal is damaged, it allows cool air to get into double-paned glass windows, causing them fog. Simple fixes may help, but the most effective solution is to replace the windows.

A spacer bar is usually located between the glass panes of most double-glazed windows. The spacer bar is a source of desiccant that absorbs any moisture and prevents it from reaching the glass. This bar is susceptible to cracking or breaking, and it's usually necessary to replace the entire window.

You can do some repairs yourself using the appropriate tools. However, it is more common to hire a professional who has been trained to do this. This will not only save you a great amount of time, but it will also ensure that your double glazing is repaired correctly and of the best quality possible. Using a trusted tradesman can also mean that you get some kind of assurance for the work done that you would not get from DIY work.

Shattering

Double glazing is a wonderful technology that lets homeowners save money on heating bills, whilst keeping their homes warm and comfortable. However, it isn't indestructible and occasionally issues may arise. These faults can be dangerous in some cases if they're not addressed promptly.

If you've noticed any issues with your double glazing that could put your family members 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 make them look ugly.

Repairing double-glazed windows can be more cost-effective than replacing them. If you've noticed any indications of issues with your double glazing, it's worth searching for local companies that specialize in repairs for double glazed windows and getting estimates. The most affordable quote might not be the best option. Be sure that the company you choose to work with offers an assurance on 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 opening in between and a rubber gasket which stops water from entering the gap. Certain IGUs also contain a gas, such as Argon that helps to prevent heat from leaving your home, thus conserving energy.

If one of the IGU panes is damaged, then you can purchase a replacement from a window maker and then fitted to the frame. This is usually less expensive than replacing the entire window and is much more affordable for the majority of households.

Based on the type of window you have and the condition of the frame, it could be possible to fix the damaged pane. If the glass has formed only a few small chips, but hasn't broken, that's usually the situation. If the double-glazed window is completely shattered then it is recommended to replace both the glass unit and the window sash.
