Can Double Glazed Windows Be Repaired? If you recently installed double glazing in your house, and it is beginning to begin to show signs of failing, you may wonder whether they are able to be repaired. You may be able to claim your double glazing covered under warranty based on the issue and when you bought it. Broken Panes If a window's pane is broken or cracked air can flow through more easily. This decreases the effectiveness of the window as an insulation barrier and also against the elements. This can cause hot or cold air to enter your home, based on the season. Heating and cooling costs will rise. If the crack is not too deep, you might be able to apply an adhesive tape with strong-hold. This is a temporary fix however, and it may only prevent the crack from growing. To get the best results, a professional window repair company should be contacted to fix any broken glass on your double-glazed windows. It can be dangerous and difficult to repair windows on your own. If the crack is too big to grasp and hold, try putting strips of masking tape across it in a crisscrossing fashion prior to trying to remove it. If the crack is small enough, you can hold it in place and use a blade to cut it off from the frame. Be sure to 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 fragments that might fall. To install a new glass pane, you'll need to purchase replacement glass and then prepare the frame. To ensure that the new glass is a good fit, measure the opening of the frame and subtract between 1/16 and 1/8 inch on both sides. Then have your replacement glass cut according to this measurement at a local glass shop or at a hardware store. If you have wooden frames, purchase points for glaziers from a local hardware store to place them on the outside of your new glass. Position the points so that they allow expansion and contraction while keeping the putty flush against the glass. Spread a thick layer with a putty knife after your new pane is installed. You can use a linseed oil-based putty such as Sarco or a less expensive product like Dap glazing compound. Fill any gaps that exist between the frame and the new pane using the compound you choose. Smooth the compound on the new pane to ensure it is even and level. Water Leaks Water leaks around a window's frame or sash can be a frequent problem. This occurs when the sealant on windows has damaged and requires replacement. Water leaks around the window can cause damage to the drywall or plaster and can cause damp walls. A double-glazed window of high quality has a gasket that expands with force when the sash is closed. Any water that comes into the area should be drained out through the weep holes in the bottom of the frame. Sometimes, the weep hole may be blocked by dirt and debris. Or, the weather stripping might need to be replaced. The lintel above the window can also be an area of leaks. The installers who built the house may not have realized that this lintel must be allowed to drain properly or they could have just clad it with concrete leaving gaps that allow rainwater to enter and pool around the window causing dampness in the wall or wood rot. The installers could have an angled fascia board above the windows to ensure that water is directed properly. This will stop water entering the building. Another possible source of leaks is the gap that exists between the glass panes in double-glazed units. A worn seal could have caused the gas argon or krypton which is supposed to be between the glass panes to provide insulation to leak out. Although this isn't a particularly serious leaky window problem however, it could affect energy efficiency and must be taken care of as soon as is possible. In this situation double glazing replacement could be necessary. A professional will conduct an exhaustive assessment and identify the cause of the leak. They can also suggest solutions. They'll also be able advise whether it is advisable to repair the window or replace it completely. They will also provide an estimate for any work that is required. Condensation Condensation may be a problem with older double-glazed windows and doors. However, this is usually a simple solution. It is caused by the lack of air flow around the windows. It is common in rooms like kitchens or bathrooms. The most obvious indication of condensation is droplets of water appearing on the glass's surface. These droplets will rapidly disappear when the window is heated by sunlight. If the issue persists it's worth looking further. Another sign of condensation is if you hear water drippy. 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 entering your home. This type of problem may also lead to mould over time, so it's recommended to get the window repaired as quickly as possible. A professional can inspect your window and recommend the best solution. Professional firms will take off the glass affected and blow hot air between the two panes. This will eliminate any remaining moisture and guarantee that a high-quality seal will be reapplied. Windowpane seals that fail are the main cause of condensation problems with double glazing. Cool air enters double-paned windows when the seal is damaged and they begin to become cloudy. If this happens it's possible that simple fixes will help, but in many cases the best solution is to replace the window. The majority of double-glazed windows feature a'spacer' bar that sits between the two panes of glass. This spacer bar is filled with desiccant which sucks up any moisture that could occur, therefore preventing it from reaching the glass panes, causing condensation. The spacer bar is susceptible to cracking or breaking, and it's often necessary to replace your entire window. You can do some repairs yourself using the correct tools. However, it is usually better to hire someone who has been trained to do this. You will save a lot of time and make sure that the double glazing is repaired properly. A reputable tradesperson will also offer a guarantee on the work they have done that you could not get if you were to repair it yourself. Shattering Double glazing is an amazing invention that allows homeowners to save money on heating costs, while keeping their homes warm and comfortable. It isn't impervious to damage, and issues can occur occasionally. These faults can be dangerous in some instances if they're not addressed quickly. Therefore, if you've noticed any issues with your double glazing that could be putting your family members in danger it is essential to fix them as soon as you can. Problems like misting and leaks of water can affect the effectiveness of the windows and cause them to look ugly. Repairing double-glazed windows can be cheaper than replacing them. If you notice any signs of trouble with your double glazing it is worth researching local companies who specialize in double-glazed window repairs and requesting estimates. Remember that the cheapest quote isn't always the most effective and ensure that the company has a warranty on their work. A double-glazed window will be sold as an Insulated Glass unit (IGU). The Insulated Glass Unit (IGU) is comprised of two glass panes that have an area between them, and a rubber gasket that keeps water from leaking through the gap. Some IGUs contain the gas argon. It keeps heat from leaving the home and saves money on energy costs. If one of the IGUs has been damaged, a replacement pane can be purchased from a window manufacturer and fitted to the frame. This is usually cheaper than replacing the entire window and is more affordable for many households. It could be possible to repair the damaged window depending on the kind of frame and condition of your window. If the glass has developed just a few tiny chips, but not been shattered, this is usually the case. If your double glazed window has completely shattered and is cracked, then it's best to replace the entire glass unit and the window sash.
