20 Fun Facts About Repairs To Double Glazed Windows
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 can be fixed.

Depending on what the problem is and the date you bought them from the store, you might be able to get your double glazing back under warranty.

Broken Panes

If a window's glass is damaged or cracked, it allows air to flow more easily, reducing the windows' effectiveness as an insulation and protection against the elements. This could cause hot or cold air to enter your home based on the time of year. Heating and cooling costs will increase.

If the crack is not too deep, you might be able to use a strong-hold adhesive tape. This is a temporary solution, though, and it will only stop the crack from getting worse. To get the best results, a reputable window repair company is required to fix any broken glass on your double-glazed windows.

The process of replacing a damaged window pane yourself can be tricky and dangerous. If the crack is too big to grasp and hold, try putting strips of masking tape across it in a crisscross pattern before trying to remove it. If the crack isn't too large you can use a razor to cut the glass from the frame. Wear gloves and a mask while cutting the glass. After the pane has been cut you must lay it flat on several layers of newspaper to keep any pieces that fall.

To install a new pane, you'll need to purchase replacement glass and then prepare the frame. To ensure that the new pane is properly fitted you must measure the opening of the window frame and subtract between 1/16 and 1/8 inches on both sides. Then have your replacement glass cut to this measurement at a local glass shop or hardware store. If you have wooden frames, you can purchase points for glaziers from a local hardware shop to install along the edge of your new glass. The points should be placed in a manner they can allow expansion and contraction while keeping the putty flush with the glass.

After the new pane has been placed, spread a thick layer of your preferred glazing compound with the help of a putty knife. Use a linseed-oil-based putty like Sarco or a cheaper product like Dap glazing compound. Fill any gaps between the frame and the new pane using the compound you choose. Be sure to smooth the compound to ensure that it is even and level around the pane.

Water Leaks

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

A good double glazed window has a gasket that is able to compress when the sash is closed. The water that is absorbed by this area should be drained through the weepholes of the frame. However, in some cases, the weep holes become blocked by a build-up debris and dirt or the weather stripping around the window could need to be replaced.

Another source of water leaks is the lintel which is a support for the brick that is above the window. The installers who built the house may not have understood that the lintel needs to be let to drain properly or they could have merely put it in concrete and left an opening where rainwater could get in and build up around the window, creating dampness in the wall or wood rot. 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 getting into the structure through these gaps.

Another source of leaks is the gap that exists between the glass panes in a double-glazed unit. A damaged seal could have caused gas argon or krypton which is supposed to be in between the glass panes to create insulation to leak out. Although this isn't the most serious problem with windows that leak but it could affect energy efficiency. It is important to address the issue as soon as is possible. In this instance double glazing replacement might be necessary. A professional can perform an extensive evaluation and reveal the source of the leak. They can also recommend solutions. They will be able to tell you whether it is advisable to fix the window or replace it completely. They will also be able to give you a price for any work required.

Condensation

Condensation is a frequent issue with older double-glazed doors and windows, but it is usually easily corrected. It is caused by a lack air flow around windows and is common in kitchens and bathrooms. The most obvious sign of condensation is droplets of water forming on the glass surface. These droplets will quickly disappear when the glass is heated by sunlight. If the issue persists it is worth investigating further.

There is also the sound of the sound of water drip. This is usually caused by a leak in the seal between the two glass panes. Repairs are highly recommended if you notice this sound. This will prevent cold drafts from entering your home. This kind of issue could also lead to mould over time, so it is best to fix the window as soon as possible.

A professional will inspect your window and recommend the best solution. Professional firms will take off the affected glass and then blow hot air between the two panes. This will evaporate any remaining moisture and ensure that a good seal is reapplied.

Failing windowpane seals are the main cause of condensation issues in double glazing. When the window seal fails, it allows cool air to get into double-paned windows, which makes them fog. If this occurs, it is possible that simple fixes can assist, but in many cases the best solution is to replace the window.

A spacer bar is usually found between the two glass panes that are found in the majority of double-glazed windows. The spacer bar is filled with desiccant, which sucks up any moisture and stops it from reaching the glass. The spacer bar is susceptible to cracking or breaking, and in most cases, you'll need to replace the entire window.

You can repair some of the issues yourself with the right tools. However, it's usually better to hire someone who is 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 properly and of the highest quality. A trusted tradesman will also provide you with a warranty on the work they have done that you wouldn't receive if you tried to repair it yourself.

Shattering

Double glazing is a fantastic technology that lets homeowners save money on heating costs, while keeping their homes warm and comfortable. It is not indestructible, and issues can occur periodically. In certain instances, these faults may even be dangerous if not addressed promptly enough.

If you notice any problems with your double-glazing that could put your family members in danger, it's important to fix them as quickly as possible. Problems such as misting or water leaks can reduce the performance of windows and cause them to appear ugly.


Repairing double-glazed windows can be more cost-effective than replacing them. If you spot any indications of trouble with your double glazing it is worth researching local companies who specialize in double glazed window repairs and getting quotes. The cheapest quote may not be the best option. Be sure that the company you choose has an assurance on their work.

Double-glazed windows are sold as an Insulated Glass unit (IGU). It is comprised of the two glass panes, the space between them and an insulating rubber seal that prevents water from leaking into the insulating gap. Some IGUs contain Argon, a gas that prevents heat from escaping the home and saves money on energy costs.

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

It may be possible to repair the damaged window dependent on the frame type and condition of the window. This is typically the case if it has only developed a few tiny cracks, but is not shattered. If the double-glazed window has completely broken, it is recommended to replace both the glass unit and the window sash.
