Double Glazed Window Repairs Double glazing is an investment that is worth it, but can be frustrating when it doesn't perform. Fortunately, most issues are repairable and you don't need to replace your windows or doors. Double-glazed windows are made up of two glass panels that are separated by a very thin gap, which is filled with insulating gas, such as argon or krypton. This increases a window's efficiency. Broken panes Double-paned windows are less likely to break than single panes of glass, however they are still susceptible to shattering or break. It is crucial to repair the broken pane of double glazing as quickly as possible in order to avoid loss of energy and moisture. Depending on the degree of the crack, you may decide to use a temporary repair or an intensive repair using epoxy. A temporary repair will help to prevent further cracking, and keep out rain and cold air. A more extensive repair will strengthen the crack and create a stronger seal. To replace a damaged double-pane window, first remove the frame from the sash and set it on a table. Then, place a grid of duct tape to the pane to keep glass pieces from falling off when you remove it. Once the tape is secured remove the double pane glass from the frame. Then you can use a wirebrush to clean the grooves and rabbets. You can also vacuum them or wipe them clean with a damp cloth. If needed, remove the wood molding and scrape off any metal or putty before putting in the replacement pane. Apply silicone caulk in the rabbets and grooves in order to ensure a tight fit. If you're trying to repair a damaged glass yourself, start by sanding the glass until it's smooth and free of paint. Heating guns can be used to soften any putty or glazing points. After the rabbet is cleaned then you can use a putty blade to push ropes into place. Make sure that the putty is a uniform thickness and press against the glass and frame in a uniform way. If you're looking for a longer-term fix, an epoxy repair is a better choice than replacing it. This is more expensive and will require a longer wait time however it can be more attractive. It also lasts longer than the temporary fix. Condensation Condensation is one of the most common double glazed window issues, but it doesn't necessarily mean your windows aren't working properly. The fact that your windows are showing condensation is actually a good indicator that your double glazing is doing what it's supposed do, keeping cold out and the warmth in. When you see condensation forming on the outside of your window, it is actually water vapor coming from the inside of your home that has cooled down and condensed onto the glass's surface. It's a natural process that won't cause harm to your windows unless you leave it on the surface long enough. The reason for condensation inside is usually too much humidity or low temperatures in the room. This causes cold surfaces, like windows, to draw in moisture that is high in dewpoint (the temperature where water turns into liquid). The humidity is also a common occurrence in kitchens and bathrooms because of the steam that comes from kettles, showers, as well as hot pots and pans used in cooking. To avoid condensation, try not to hang wet clothing close to windows. Also, make sure that your uPVC frames have plenty of air circulation to prevent the accumulation of moisture. You should also ensure that your double glazed windows are properly insulated and fitted with the correct gap (6mm is the ideal) to ensure maximum energy efficiency. You can also try adding air vents that are one-way to your windows to improve insulation. If you're still experiencing condensation, however, then there's probably a problem with the seals or gaskets and this is definitely something that should be handled by an expert. Draughts A window that isn't draughty is an indication that the seal between the glass panes of your double-glazing has started to leak, and is likely to require replacement. This can impact the insulation of your home and increase the cost of energy. A window repair service can replace the sealed unit for you, and restore the effectiveness of your windows. They can also replace existing frames with new energy-efficient features, including glass units that are filled with argon, as well as thermal spacer bars to reduce heat loss, and cut down on heating costs. Draughts can be caused by problems with the locking mechanisms of double glazed windows, so it's worth getting these checked. Older uPVC window locks are infamous for becoming stiff with time however, it's simple to fix this issue by lubricating them regularly with a specialist uPVC cleaning product. A professional double glazing business can ensure that your repair is done properly. They will have the right tools to ensure that your window is completely resealed and watertight. They can also repair any damage to the frame so you can take advantage of your new double glazing. Double-glazed windows last a long time and durable, but they may develop issues as a result of wear and tear or weather. Contact your local double-glazing repair company as soon as you spot any of these issues. You'll be glad you did – a well-repaired double glazing installation will give your house that tangible feeling of quality and will also help you save money on your energy bills! Smudging Double-glazed windows comprise two separate panes with a spacer, air or dense gas between them to make an effective seal that blocks heat from passing through the frame. They're a great option to reduce energy consumption and the carbon footprint of your home. However, double glazing may have a range of issues that could impact its performance and longevity. These include fog, condensation, and difficulties to close or open. If you are having trouble opening your double-glazed windows, it could be because of the weather. It could also be a issue with the hinges, or handles. It is possible to solve the issue by wiping down and lubricating the windows with cold water. Contact the company who provided you with windows as early as you can to fix them. This is another issue which can be easily fixed. upvc window repairs is always worth checking your warranty to see if there are any repairs covered. Fogged or foggy glass can be caused by moisture in the panes. It's typically a sign that the seals aren't functioning properly or your double-glazing unit needs to be replaced. This is a simple solution that can be achieved without having to replace the whole window. To correct this issue A technician will make tiny holes to vent out any moisture between the glass panes and the rest of the window. After the moisture has been removed, a new antifog coating is applied and the window is sealed. Sometimes the window will need to be removed but, in most instances, it can be done within the home. Mist Double glazing that is older may be prone to mist, especially when it happens both inside and outside the window. This is due to a failure of the seal that is designed to keep air and moisture between the two panes. The seal is made during the production of double-glazed units by sealing the two panes using an airtight polysulphide or butyl seal around the edges and spacer bar. This seal is designed to stop the window from leaking and provide insulation. If you have misted double glazed windows, it may be a challenge to remove and clean, as you'll need to break the hardened seal to clean. The problem with mists is that they permit moisture to get in, which leads to condensation between the glass panes. This is because there is a large difference in temperature between the internal and external surfaces of the glass. The moisture is trapped within the gaps, resulting in the appearance of milky. This can be quite ugly and it can be difficult to get rid of. Some companies claim that they can repair misting double-glazed windows by drilling holes in the unit and injecting a chemical through the holes that absorb moisture from the inside. But, this isn't an end-to-end solution to the issue and it's much easier to replace the entire double-glazed unit if experiencing misting. The best way to avoid misty double glazing is by maintaining a high level of ventilation and cleaning your windows regularly. It's also a good idea to use extractor fans in kitchens and bathrooms and wipe windows with an damp cloth to minimize the build-up of moisture. If you are unable to avoid the issue completely, we recommend replacing your double-glazed units with A-rated ones to improve the efficiency of your energy usage.
