Can Double Glazed Windows Be Repaired?

If you've recently had double glazing installed in your home and are beginning to show signs of failing you might be wondering if they could be repaired.

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

Broken Panes

If a window's pane is damaged or cracked it allows air to flow more easily, reducing the effectiveness of windows as insulation and barrier against the elements. This can cause hot or cold air to enter your home based on the time of year. The cost of cooling and heating will rise.

If the crack in your double glazing isn't too deep, it might be possible to apply a strong-hold tape. This is temporary fix, and may only stop the crack from becoming more severe. To get the best results, a professional window repair company should be called to repair any damaged glass that is present in your double glazed windows.

It could be risky and difficult to upvc repair windows on your own. If the crack is extensive and difficult to remove Try applying strips of masking tap in a crisscrossing pattern. If the crack is small enough that you can keep it in place and use a razor blade to remove it from the frame. Wear gloves and a mask when cutting the glass. When the pane is cut free 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 prepare the frame. To ensure that the new pane fits properly, measure the opening of the frame and subtract between 1/16 and 1/8 inches on both sides. Then, have the replacement glass cut according to this measurement at your local glass shop or hardware store. If you have wooden frames, purchase points for glaziers from an hardware store to place along the edges of your new pane. Be sure to install the points in a position that allows expansion and contraction while keeping the putty flat against the glass.

Once your new pane has been placed then spread a thick layer of your glazing compound using a putty knife. Make use of a linseed-oil-based glue like Sarco or a less expensive product like Dap glazing compound. If you notice any gaps between your new pane and the frame, fill them in with the chosen compound. Be sure to smooth the compound to ensure that it is level and even all around your pane.

Water Leaks

The presence of water leaks around the frame or sash is a common problem that occurs when window sealant has become degraded and requires replacement. Water leaks around the window could damage the drywall or plaster and cause damp walls.

A high-quality double-glazed window will have a gasket that will firmly compress when the sash is shut. The water that is absorbed by this area must be drained out through the weepholes in the frame. However, in some cases, the weep holes are blocked by a build-up of dirt and debris or the weather stripping around the window may need to be replaced.

Another potential culprit of water leaks is the lintel which is a support for the brick that is above the window. The people who built the house may not have realized that this lintel should be allowed to drain properly, or they could have merely clad it with concrete leaving gaps that allow rainwater to be able to enter and collect around the window, causing dampness in the wall or rot in the wood. The installers should have placed the fascia boards in a slant above the window to ensure that the water is directed properly. 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 the double-glazed unit. It's possible that the argon or krypton gas that is supposed to be in between the glass panes to provide insulation has leaked out of the windows because of a worn out seal. Although this isn't the most severe leaky window issue it can affect energy efficiency and must be addressed as soon as possible. In this instance replacement double glazing might be appropriate. A professional can complete an exhaustive evaluation, letting you know where the leak is coming from and suggest a solution. They'll be able to tell you whether it is appropriate to fix the window or replace it completely. They can also provide an estimate for any work that is required.

Condensation

Condensation is a very common issue with older double-glazed doors and windows, however this can usually be easily fixed. This is due to an absence of air flow around the window, and typically is seen in rooms like kitchens or bathrooms. The most obvious evidence of condensation is the appearance of 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 investigating further.

It is also possible to hear the sound of water drip. This is most likely due to a broken 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 can cause mould in the long term, so it is best to have the window repaired as soon as you can.

A professional can examine your window and suggest the best solution. Professional companies will remove the glass that is affected and blow hot air between the two panes. This will eliminate any moisture that remains and ensure that a good seal will be reapplied.

Windowpane seals that fail are the main cause of condensation problems with double glazing. If the window seal is damaged, it allows cool air to enter double-paned glass windows, making them to fog. Simple fixes may help, but often the best solution is to replace the windows.

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 a source of desiccant, which sucks up any moisture and blocks it from getting into the glass. This spacer bar is prone to cracking or breaking, and it's usually necessary to replace your entire window.

You can make some repairs yourself using the correct tools. However, it is more common to hire a professional who is skilled in doing this. This will not only save you a great amount of time, it will also ensure that your double glazing is repaired correctly and with the highest quality. A trusted tradesman will also offer a guarantee on the work done that you could not get if you attempted to repair it yourself.

Shattering

Double glazing is an innovative product that lets homeowners save on heating costs while keeping their homes warm. It isn't impervious to damage, and issues can occur from time to time. In some instances these flaws could 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 crucial to fix them as soon as you can. Issues like misting and water leaks can compromise the performance of windows and make them look ugly.

Repairing double-glazed windows is typically more cost-effective than replacing them. If you see any indications of trouble in your double glazing, it's 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 most effective and ensure that your chosen company has a warranty on their work.

If a double-glazed window is sold, it will be contained in an Insulated Glass Unit (IGU). The Insulated Glass Unit (IGU) is comprised of two glass panes, with a space in between, and a rubber gasket which keeps water from leaking through the gap. Certain IGUs contain the gas argon. It keeps heat from leaving the home and saves you money on energy costs.

If one of the IGU panes is damaged, it is possible to purchase a replacement from a window manufacturer and then installed on the frame. This is usually less expensive than replacing the entire window and is more affordable for a lot of households.

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