Double Glazing Repairs Repairs may be needed when double-glazed windows become difficult to open or exhibit signs of condensation. In most cases it is possible to fix the issue without the need to replace the entire window unit. Attempting to fix your own double-glazing requires specialized tools, which is why this is best left to a professional. Condensation The sight of condensation in your double-glazed windows isn't just an inconvenience, it also means that warm air is exiting your home. It's usually a sign the seal is broken or is beginning to break. It is best to replace the entire window if that's the case. In certain cases you may be able to use a hairdryer (from an appropriate distance) to eliminate the moisture from between the glass panes. This is a great temporary solution, but it's important to remember that you should seek professional help whenever you can, as the longer the issue persists for a long time, the more damage it can cause to the double glazing, and possibly to your health as well. If the condensation is only in a small area of your window frame you are usually able to eliminate it by wiping it off quickly and frequently. However, if you see condensation over larger areas of the window, it could indicate that the seal has been damaged and windows are now less thermally efficient than they should be. It can be caused by a variety of causes, but the most common are high humidity or inadequate ventilation in your home. Double-glazed windows will show more condensation than older single pane windows due to the fact that humidity can easily form droplets of water on cold surfaces. If your bathroom or kitchen are particularly humid, you might require installing a vent to help reduce the humidity levels. If your windows are under warranty, you can call their installer to discuss the issue and request to address the issue. They may be able to replace the window, or they may need to install one-way vents to stop future condensation. This is a better option than replacing your double-glazed windows as you will save time and money. Foggy Glass The presence of fog in windows is a sign of a failed seal in double-pane windows. These windows have two glass panes with an opening between them, and this space is filled with energy-efficient gases such as argon or krypton. This helps keep temperature-controlled air inside your home, while keeping the outside elements out. However, if the seal is damaged, moisture can enter and cause fog. Foggy windows can make your home less efficient and unattractive. While windows can be replaced when they're leaking most homeowners prefer hiring an expert to repair their windows instead. Before making recommendations, a glass specialist can help determine if the windows can be repaired. If they must be replaced, a glass specialist can provide you with high-quality replacements that aren't likely to get clogged. Double glazing can also cause problems when it comes to the opening and closing of windows or doors. This can be caused by extreme weather conditions or a change in the structure of the frame. If you notice that your double glazing is difficult to open, the first step is to speak to the business you purchased it from. The majority of companies offer warranties that cover their products for a specific period of time, and some offer lifetime warranties. If you cannot resolve the issue with your provider it could be the right time to switch providers. Always request an official confirmation of your complaint, any agreements made and the dates. This will make it easier to switch providers if necessary. Windows that have become cloudy can be fixed through defogging, a process which involves drilling holes into the window, injecting cleaning solution and then removing the soiled liquid and drying the inside of the glass. Before you decide to go with this method it is important to determine whether it's appropriate for your home. Remember, however that it can't bring back any energy efficiency lost due to damaged window seals. Cracked Panes A crack in a double-glazed window might appear to be a minor issue but it can cause significant damage. It's crucial to have the crack fixed as quickly as you can in order to prevent further damage, especially if it's on the inside of the glass. Double-pane windows are made up of two glass panes connected with a space between that is filled with an inert gas, like argon or Krypton. This is to prevent heat from your house from moving through the glass. The gas slows heat transfer, so the warm air from your home may travel through the window at a slower pace than if there were nothing between the panes of the glass. During installation, it's important that the windows are fitted correctly and have a top-quality seal. https://www.repairmywindowsanddoors.co.uk/double-glazing-repairs-swindon/ should be fitted by a glazier who is qualified, who can fit the panes of glass with a seal that is tight to ensure that they're insulated as effectively as possible. If the window seal has failed it may cause the gas inside the panes to leak out, reducing their insulating properties and resulting in cracking between the two panes of glass. Another common reason for cracked double-pane windows can be due to poor installation, which can lead to the glass expanding and contracting at different rates. This could cause stress cracks to appear over time, weakening the glass. If this is the case, you need to find a good glazier who will be capable of replacing the damaged pane of glass with a new one that is more appropriate for your home. If you find a small crack in your double-glazed windows, it is crucial to understand that the crack can't be repaired by filling it in with adhesive. Double-paned windows require a tight seal between the two panes, and cracks can only get worse over time. It is crucial to keep in mind that broken glass is dangerous. Therefore, it's best to call a professional who has the proper tools to complete the task. They will also be able to take the old sealant from the glass without causing further damage. Seals that leak The IGU consists of three or more sheets that are joined by annealed glass or the tempered. The IGU is held together by a combination of polyurethane and spacers made from aluminum, which forms an airtight seal between the windows that prevents moisture from penetrating your home. As time passes, the seal may break down and allow water to leak into. This is usually due to the natural expansion or contraction of the materials that were used to make your window. The sealant, whether polyurethane or silicone, may stretch and shrink slightly with changes in humidity and temperature, putting the IGU at risk of breaking down. When the seal is damaged, the insulative fill-gas can escape and your windows will be left with a cloudy appearance and draughts which reduce the efficiency of your home. If a window seal is damaged, it can also cause condensation or water between the panes that are difficult to wipe away. In some instances, water may leave a permanent stain left on the glass of your window. Generally, you can fix the problem by having your windows professionally cleaned and sealed. This procedure requires professional equipment to remove water, fill the void with argon, or krypton gas, and reseal without letting the gas escape. The cost of this service can differ based on the type of IGU and your location, but most double-glazed windows can be repaired within an hour or two. In addition to changing your window seals there are other ways to improve the efficiency of double-pane windows. Select energy-efficient coatings and glass that reflect instead of absorbing the sun's rays. This will keep your living spaces cooler, more comfortable and improve the appearance of your windows. Finally, apply caulk or weatherstripping around your frame of your window to stop gaps that can let cold air into your home and warm air out. In some instances it is a better alternative to replacing the whole window.
