How to Repair Double Glazed Windows Typically, double glazing comes with a guarantee of 10 or 20 years. If your double-glazed windows show signs of aging, you might be eligible for them to be repaired under warranty. Double-glazed window repair involves the re-sealing of your glass unit. Misting is a clear indicator that the seal has failed and you have to have it fixed. Damaged Glass Double pane windows depend on an airtight seal to function correctly. The most common indication that a seal is failing is the formation of condensation between the glass plates. While condensation between glass is not an issue that needs to be dealt with, it's typically an indication that the glazing unit is in need of replacement. If you have an older double-glazed window, this may mean replacing both the frame and the glass. If the frame is in good condition, you may be able to save money by only replacing the glass. Glass is fragile, and it's not uncommon for double-pane windows that develop cracks as time passes. Unless the cracks are caused by mechanical damage or an unusual impact, it's possible to repair the cracks using epoxy and a small amount of elbow grease. Start by cleaning over the crack using a moist cotton rag. Next, apply epoxy to the crack following the instructions of the manufacturer. Allow the epoxy to fully dry before sanding and painting over the repaired area. A simple strip of masking tap can also be used to stop cracks from spreading. One strip of tape placed on both sides of the crack area should be enough to stop superficial cracks, like stress cracks that result from low temperatures, from worsening. However, if you're dealing more serious cracks that have already formed in your glass, it could be better to contact an expert to ensure the security of the repair. It is risky and difficult to replace a single pane in a double-paned window. Double-pane windows are constructed as a whole unit and sealed at the factory using inert gas. Therefore, it's impossible to remove the glass without causing damage to the entire window. If you plan to replace the glass in your double-paned windows pick a manufacturer with an extensive warranty. It's also recommended to cover the window frame with newspaper prior to when you attempt to remove the sash and replace any damaged glass. This will help protect yourself from sharp shards that could fall in the process, and it'll also help to prevent any damage to the trim of your home or molding. Condensation Build-Up It's important to know that condensation between the windows can be normal. It's due to a gap between the temperature of air and humidity levels that cause water vapour in the air to condense when it comes in contact with cold, hard surfaces like windows. Usually this is a good thing, especially in winter, as it can help prevent heat loss. However, if you're finding that your windows are looking like they're cloudy, with a film of water on them, it's time to call in an experienced Glazier. This is a sign that the 'air gap seal between the two panes of glass has begun to weaken and allowing moisture into the window. You can stop this from happening by using a dehumidifier, improving ventilation or applying a de-icing agent. There are companies that will remove excess moisture from double-glazed windows through drilling into the unit and injecting desiccant. This requires removal of the sealed unit from the frame and then cleaning each pane of the glass before refilling the desiccant. This is usually more expensive, however it is worth checking whether the company you select is insured and is registered with FENSA. It is important to keep in mind that tampering with your double-glazed windows is not recommended and could invalidate any guarantees. If you have a guarantee on your windows, it's recommended to let the company know about any problems that arise, as they will be accountable for the replacement of windows that are covered under warranty. It is recommended to speak with an expert before undertaking any DIY repairs. This is particularly applicable to older units, because they're more likely than modern ones to fail. If this happens, it's probably recommended to replace the entire glazed panel. The result will be brand new windows that will last many years. Scratches Double-glazed windows are not impervious to scratches. This can be due to environmental factors, or the manner in which the window was put in place. Fortunately, the majority of these scratches are superficial and can be repaired by using a few home remedies that you can do yourself. If your windows are damaged to the point where you can feel them with your finger it is recommended to seek out a professional for help to ensure that the glass surface is restored to its original state. These scratches are caused by objects like tree branches, pet nails, and cleaning materials that are abrasive scrape against the glass of your windows. Often, these scratches can be removed with some non-abrasive solutions such as iron oxide or cerium oxide polishes which you'll need to continue using until the scratch is no longer visible. Scratches may also occur when finishing sanding wood trim close to your windows. They may also occur in the course of construction. These scratches may be difficult for you to fix. However, a mix of baking soda and water can help smooth out the surface after buffing and eliminate any remaining scratch. Metal polish can be used to remove deeper scratches. Add a small amount the product to a cotton ball or clean microfibre cloth and gently rub over the affected area in an upward motion. Be cautious not to apply too much pressure since this could cause damage to the glass. Once the area is smoothed, apply a damp cloth to wash away any remaining polish. Think about purchasing a non-abrasive glass polish if you have an extremely deep scratch that you can't remove. You can purchase this at any DIY store. Follow the directions on the packaging. You can also use nail polish to cover up any superficial scratches on the glass of your window. Ensure that the nail polish is clear and that it is only applied to the scratched part of your window. Haze The presence of haze within your double-paned window means that the seal between the two panes is broken. It's important to have this repaired as soon as possible to avoid ending having dirt and moisture build-up between the panes. This could cause damage to the glass and reduce its transparency. There are a number of ways to eliminate haze from your double pane windows. One option is to apply an anti-fogging spray. However, this is only an interim solution. If you're looking for a lasting solution, seek out a professional glazing company that can repair the problem and replace the gaskets if needed. A carbide-tipped tool can be used to drill tiny holes into the frame of the window to eliminate the haze. You can then insert a desiccate pack into these holes, and then wash the window with rubbing alcohol. The water will help remove the haze off the window and clean it. It is essential to keep your windows well maintained and cleaned regularly to avoid fogging. This will keep the double panes clean and let you enjoy the beautiful view of your garden or home. In addition, ensuring that your home is ventilated is also beneficial. This will help to ensure that any condensation is quickly eliminated, rather than being allowed to settle and then reseal the window. In addition to the regular cleaning and maintenance, you should also make sure that your windows are properly installed. The installation of your windows should be done by a company that has experience. This will ensure that the gaskets are fitted properly and have an exact fit.
