Can Double Glazed Windows Be Repaired?

If you've recently installed double glazing in your home and it is beginning to show signs that they are failing, you might be wondering if they can still be repaired.

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

Broken Panes

When a window pane is damaged or cracked air can flow through more easily. This decreases the effectiveness of the window as an insulation barrier and also against the elements. This can allow cold or hot air to enter your home depending on the time of year. Heating and cooling costs will rise.

If the crack isn't too deep, you might be able to apply a strong-hold adhesive tape. This is temporary fix, and will just stop the crack from becoming worse. A reputable window repair service can fix any broken glass that has been smashed on double-glazed windows.

Attempting to replace a broken window pane yourself is tricky and dangerous. If the crack is too big to grasp then try pressing strips of masking tape across it in a crisscrossing fashion prior to trying to remove it. If the crack isn't too large, you can use a razor to cut the glass away from the frame. Wear gloves and a mask while cutting the glass. After the pane has been cut it is necessary to lay it flat on several layers of newspaper to keep any pieces that fall.

To install a new glass pane, you'll need to buy replacement glass and set up the frame. To ensure that the new pane is properly fitted take a measurement of the opening of the window frame and subtract between 1/16 and 1/8 inches on both sides. Cut your replacement glass at a local hardware or glass shop according to this measurement. If you have wood frames, you can purchase points for glaziers from an hardware store to place along the edges of your new pane. The points should be placed in a manner they can allow for expansion and contraction, while keeping the putty flush against the glass.

Spread a thick layer using the blade of a putty maker after your new pane is installed. You can make use of a linseed oil-based glue like Sarco, or a cheaper product such as Dap glazing compound. Fill any gaps between the frame and the new pane using the appropriate compound. Smooth the compound around your new pane to ensure it is level and even.

Water Leaks

The appearance of water leaks around the frame or sash is a common problem that occurs when window sealant has become degraded and needs to be replaced. Water leaks can cause damage to the drywall and plaster surrounding the window. They can also result in damp or spongy walls that require to be restored as quickly as is possible.

A high-quality double-glazed window will have a gasket that will firmly compress when the sash is shut. Any water that gets into this area must be drained away through the weep holes at the bottom of the frame. However, sometimes the weep holes get blocked by a build-up debris and dirt or the weather stripping around the window might need to be replaced.

The lintel above the window could also be a source of leaks. The people who built the house may not have understood that the lintel needs to be allowed to drain properly, or they could have merely clad it with concrete leaving an opening where rainwater could enter and pool around the window causing dampness in the wall or rot in the wood. The builders should have bent the fascia boards over the window to ensure that the water is directed correctly and this will prevent water from entering the building through these gaps.

Another potential leak source is the gap between the glass panes in a double-glazed unit. It is possible that the gas argon or krypton that should be between the glass panes to provide insulation has escaped out from the windows due to the seal being worn out. While this isn't the most serious issue with leaky windows but it could affect energy efficiency. It should be addressed as quickly as possible. In this case replacement double glazing might be a good idea. A professional will conduct a full evaluation and window repairs let you know the source of the leak. They can also recommend solutions. They'll also be able advise whether it is appropriate to repair the window or replace it completely. They can also provide an estimate for any work that is needed.

Condensation

Condensation is quite a common issue with older double-glazed windows and doors, but it is usually easily corrected. It is caused by an absence of air circulation around windows and is common in kitchens and bathrooms. The most evident indication of condensation is droplets of water appearing on the glass surface. These droplets will evaporate quickly when the window is heated by sunlight. If the problem persists, it's worth looking into further.

Another sign of condensation is if you hear water drippy. This is most likely because of a broken seal between the two glass panes. Repairs are highly recommended if you notice this noise. This will stop cold drafts entering your home. This type of issue can also lead to mould over time, so it is best to get the window repaired as quickly as possible.

A professional will inspect your window and recommend the best solution. Professional firms will take off the glass that is affected and blow hot air between the two panes. This will dry out any remaining moisture and guarantee that a high-quality seal will be reapplied.

Double condensation in the glazing is caused by windowpane seals. When the window seal fails it allows cool air into double-paned glass windows, causing them fog. Simple fixes can help, but often the best solution is to replace the windows.

A spacer bar is typically found between the two glass panes that are found in the majority of double-glazed windows. The spacer bar is stuffed with desiccant which sucks up any moisture that may occur, thus stopping it from getting to the glass panes and creating condensation. This spacer bar is prone to breaking or cracking and in most cases, you'll need to replace the entire window.

It is possible to do repairs yourself if you have the right tools, but it's generally better to employ a trained professional to do this for you. You'll save a lot of time and ensure that the double-glazing is repaired properly. Using a trusted tradesman can be a good idea as it will give you some kind of assurance for the work that is completed that you can't get from DIY work.

Shattering

Double glazing is an amazing invention that allows homeowners to save money on heating bills while keeping their homes warm and comfortable. It's not impervious to damage, and issues can occur periodically. In certain instances, these faults may even be dangerous if they are not addressed quickly enough.

If you find any issues in your double-glazing that could put your family in danger, it's important to fix them as soon as you can. Faults such as misting and leaks of water can affect the performance of windows, and can leave them looking unsightly.

It is often far cheaper to fix your double-glazed windows than it would be to replace them entirely. If you notice any signs of trouble in your double glazing it is worth looking into local companies that specialize in double-glazed window repairs and getting quotes. Be aware that the most affordable quote isn't always the best choice and ensure that the company has a warranty on their work.

A double-glazed window will be sold in an Insulated Glass unit (IGU). The Insulated Glass Unit (IGU) is comprised of two glass panes that have a space in between, and a rubber gasket which stops water from entering the gap. Some IGUs also contain a gas like Argon that helps to prevent heat from escaping your home, therefore saving you on energy costs.

If one of the IGUs is damaged, it is possible to replace the pane purchased from a window maker and fitted to the frame. This is typically less expensive than replacing the entire window and is more affordable for a lot of households.

Depending on the type of window you own and the condition of the frame, it might be possible to simply repair the damaged part. This is usually the case if it's only developed a few small cracks, but is not damaged. If your double-glazed window is completely cracked and cracked, it's likely to replace the entire glass unit and window sash.
