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 failure, you might be wondering if they are able to be fixed.

Depending on what the issue is and how long ago you purchased them, you may be eligible to receive your double glazing replaced under warranty.

Broken Panes

If a window pane becomes cracked or broken it allows air to pass more easily, lowering the effectiveness of windows as insulation and protection against the elements. Depending on the season this could cause cold or hot air to flow into or out of your home, increasing heating and cooling costs.

If the crack is not too deep, you might be able to utilize a strong-hold adhesive tape. This is temporary fix and could only stop the crack from becoming worse. To get the best results, a reputable window repair company should be contacted to fix any damaged glass in double-glazed windows.

Removing a damaged window pane yourself is challenging and potentially dangerous. If the crack is large and difficult to remove, you can try applying strips of masking tape in a crisscrossing pattern. If the crack isn't too large it is possible to employ a slicing tool to cut the glass away from the frame. Make sure you wear gloves and a face mask when cutting glass. Once the glass is removed and laid flat, you can place it on several layers of newspaper to catch any pieces that might fall.

To install a new pane, you will need to purchase replacement glass and prepare the frame. To ensure that your new glass is a good fit you must measure the opening of the window frame and subtract between 1/16 and 1/8 inch 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 points for glaziers from a hardware store to place them on the edges of your new glass. Place the points in a way that they allow expansion and contraction while keeping the putty flush with the glass.

Once your new pane is set then spread an even layer of your preferred glazing compound using a putty knife. You can make use of a linseed oil-based glue like Sarco, or a cheaper product such as Dap glazing compound. If you have any gaps between your new pane and the frame you can fill them in with the compound you choose. Make sure you smooth the compound to ensure it is level and even around the pane.

Water Leaks

Water leaks around a window's frame or sash are a typical problem. This happens when the window sealant has damaged and requires replacement. Water leaks around windows could damage the drywall or plaster and cause damp walls.

A double-glazed window that is of good quality will come with a gasket that expands with force when the sash closes. The water that enters this area must be drained through the weep holes in the frame. Sometimes, the weep holes become blocked due to dirt and other debris. Or, the weather stripping may need replacing.

Another potential culprit of water leaks is the lintel, which holds the bricks over the window. The people who built the home may not have been aware that this lintel should be let to drain properly or they could have merely covered it with concrete, leaving a gap where rainwater can enter and pool around the window, causing dampness in the wall or rot in the wood. The builders should have placed the fascia boards in a slant above the window to ensure that water is directed properly. This will stop water from getting into the structure through these gaps.

A gap between the glass panes of a double-glazed window could also be the cause of leaks. A worn seal could have caused gas argon or krypton which is supposed to be in between the glass panes to create insulation to leak out. While this isn't the most severe leaky window issue however, it could affect energy efficiency and should be addressed as soon as possible. In this instance replacing double glazing could be the best option. A professional will conduct an extensive evaluation, let you know where the leak is coming from and recommend solutions. They will be able to tell you whether it is advisable to fix the window or replace it completely. They can also give you an estimate for any work needed.

Condensation

Condensation is a frequent issue with older double-glazed doors and windows, but it is usually easily corrected. This is due to a lack air flow around the windows and occurs in kitchens and bathrooms. The most evident sign of condensation is water droplets forming on the glass's surface. The droplets will quickly evaporate when the window is heated up by sunlight. However, if the issue persists it is worth investigating further.

Another indicator of condensation is if you hear water drips. This is usually because of a broken seal between the two glass panes. Repairs are highly recommended if you hear this noise. This will prevent cold drafts from entering your home. This type of problem may also lead to mould over time, so it's best to fix the window as quickly as possible.

A professional can inspect your window and suggest the best solution. Professional companies will remove the glass affected and double glazing blow hot air between the two panes. This will evaporate any moisture that remains and ensure that a high-quality seal will be reapplied.

Double condensation on glazing is caused by windowpane seals. Cool air enters double-paned windows when the window seal is damaged and causes them to get clogged. If this occurs, it is possible that simple fixes can help, but in many instances, the best option is to replace the window.

Most double glazed windows have an "espacer" bar that is placed between the two panes of glass. The spacer bar is a source of desiccant that absorbs any moisture and blocks it from reaching the glass. This bar is susceptible to breaking or cracking, and in most cases, you'll need to replace your entire window.

It is possible to carry out repairs yourself if you have the right tools, but it's generally better to employ an experienced professional to carry out this for you. This will not just save you a good amount of time, but it will also ensure that your double-glazing is repaired correctly and of the highest possible quality. Using a trusted tradesman can also mean that you get some form of guarantee for the work carried out that you can't get from DIY work.

Shattering

Double glazing is an amazing innovation that allows homeowners to save money on heating bills, whilst keeping their homes warm and comfortable. It is not indestructible, and issues can occur from time to time. In some cases, these faults may even be dangerous if not dealt with promptly enough.

If you spot any issues in your double-glazing that could put your family members in danger, it's crucial to fix them as quickly as you can. Issues like misting and leaks of water can affect the effectiveness of windows and cause them to look unsightly.

It's usually cheaper to repair your double-glazed windows than to replace them entirely. If you've noticed any indications of issues with your double glazing, you should consider researching local companies that specialise 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.

When a double-glazed window is sold, it will be contained in an Insulated Glass Unit (IGU). This is what consists of two glass panes, a gap between them, and a rubber seal that keeps water from getting into the gap that acts as an insulation. Some IGUs contain Argon, a gas that stops heat from escaping the house and helps save money on energy costs.

If one of the IGU panes is damaged, it is possible to purchase a replacement from a window maker and then fitted to the frame. This is normally far cheaper than replacing the whole window and is more affordable for the majority of households.

Depending on the kind of window you have and the condition of the frame, it might be possible to simply repair the damaged part. If the glass has developed just a few tiny chips, but hasn't shattered, this is usually the case. If your double-glazed window is completely cracked and is cracked, then it's best to replace the entire glass unit as well as window sash.
