A Provocative Rant About Sealed Window Repair
Why It's Important to Repair a Broken Window Seal The presence of condensation on windows that cannot be removed is a sign that the window seal is damaged. It also affects the insulation capacity of your home and could cause distortion of views through the glass panes. While defogging your windows can temporarily solve the problem, a permanent solution involves replacing the glass unit that is insulated (IGU). This should be handled by a reputable window company to ensure that the replacement is done properly. Contraction and expansion Over time, seals in dual pane windows break down due to expansion and contraction of the spacer that separates the glass. This is due to the temperature cycles that occur throughout the day. As the glass expands as the sun heats it the seal is put under pressure. In the evening, as the glass cools it shrinks the window seal. These constant contractions and expansions can result in a break in the window seal allowing humidity to enter the window, causing fog between the glass panes. The inert gases, like argon that are trapped between the window panes also escape through this break in the seal. This reduces the insulating properties of the window. The presence of stains or mold along the edge of double-pane windows are also indications of a damaged seal. You might also notice a rise in your energy bills or feel drafts coming from the windows. At this point, your window frames could also pull away from walls or shift. This is a sign you must replace the window seal. Replacing the seals in windows with dual panes is a fairly complex and labor-intensive task that typically involves removing the old seal and the new one, cleaning both windows, and replacing the IGU. While it is possible to replace the IGU on your own but hiring a professional highly recommended. This process is prone to errors that can cause water damage and pest infestation. A professional will also assist you in determining the best repair solution to your situation and can provide guidance on a long-term plan to keep your window sealed correctly. This could include a short-term solution, such as sealing the gap between the window frame and the wall to stop water and bugs from entering your home, or it could require replacing the entire window with an IGU that is more resistant to weather conditions and damage to the seal. You can also install an entirely new window that has an alternative IGU with an improved seal or better suited to the climate of your home. Weather Conditions Although window seals are constructed to withstand the harshest conditions in the weather, continuous exposure to the elements could eventually cause them to fail. The most common culprits are extreme temperature changes that can cause the glass to expand and contract, putting pressure on the window seal over time. This is especially the case for homes situated in climates that have hot summers and cold winters. High humidity, storms, and other environmental conditions can also affect window seals. Wind particularly can be very hard on windows, causing them to move or loosen over time. When this happens air can get infiltrated between the glass panes in an insulating window, leading to fogging or condensation. While fogging isn't a danger to your safety but it can affect the appearance of your windows and make them difficult to see through. Water and humidity can also cause window seals to degrade by causing rot on the frame or growth of mold. If you are experiencing these issues, it's likely that the window seals will need to be replaced. Another common sign that window seals are starting to fail is higher energy bills. If the window seals are damaged the cooling and heating systems will need to work harder to keep your family members and you at ease. This can result in higher utility costs. You may also notice that it is becoming more difficult to open and close your windows. This indicates that the window seal has become stiff, which is preventing it from properly opening and closing. This issue must be addressed before it becomes a major problem and your windows will not be as energy-efficient as they could be. You can prolong the life of your window seals by following the maintenance instructions of the manufacturer. This includes cleaning them regularly with a mild detergent or other approved cleaning agent and ensuring that they are free of dirt and debris. Avoid using heat gun and chemical strippers to clean your windows. They are able to degrade the sealant. Damage Modern triple and double pane windows differ from the old single-paned windows. They have glass panes separated by an air space and then sealed around the edges. This keeps the humidity out. The spaces between the glass panes are filled with an inert gas, such as argon or krypton in order to limit the transfer of cold or heat outside the window. These kinds of windows are also known as insulated glass units (IGUs). If you notice condensation or indications of broken window seals, it's recommended to call a professional to evaluate the situation and decide the best way to proceed. Ignoring the issue will only increase the severity of the issue which will result in higher energy bills and a more obvious impact on your home's comfort. Generally speaking, content is to replace the IGU, while preserving the existing window frame. This is especially beneficial if the current frame is in good condition and has a higher R-rating than the windows you originally had and allows you to preserve an impressive amount of insulation efficiency. However, if the current frame is in poor condition or outdated and has other external damage, a complete window replacement might be the most effective option for optimal energy efficiency and protection. This type repair can be accomplished quickly and easily by a professional, and can improve the appearance of your house while restoring the window's insulation properties. If your window is covered by warranty, the manufacturer or installer may be willing to replace or repair the damaged IGU for no cost. Review the window's warranty or contact the original installer to find out whether this is a possibility in your case. Installation Window seals are vital to stop drafts from entering and maintaining energy efficiency in your home. Not only is it vital to repair a damaged seal as soon as you spot it but also to perform preventative maintenance to avoid future problems. Window maintenance is an ongoing procedure that involves regularly checking for gaps and cracks and re-caulking when required, and cleaning. Re-caulk the window seals at least once each year to limit the effects of temperature and moisture. This is particularly important for older homes where foundations have settled since their initial installation. Regularly checking your windows for damage helps you spot any issues before they develop into an unsound seal, and you can make an appointment with a professional for a repair as required. If you notice condensation on your window panes, it's an indication that the frame and glass aren't properly sealed and can result in poor indoor air quality. If you also hear a tapping sound when you push on your window, it's a sign that the window is damaged and in need of repair. The window seal could break when the frame of the window is damaged. This can happen if your pets or children accidentally smash the window with a broom, or if harsh cleaning products like paint strippers are sprayed too close to windows. It can also occur when windows are fitted with aluminum frames, which do not provide the same insulation as wood or fiberglass. A damaged seal should be repaired or replaced if the windows are still under warranty. This will not only guarantee your window is repaired or replaced quickly however, it could provide you with the chance to upgrade to a more energy-efficient frame material, like wood or fiberglass. If you have a broken glass unit that is insulated, it's usually best to seek out a professional who can replace it. This is the most cost-effective way to go. It's important to note, however that many windows come with removable IGUs that contain insulating gas that allows you to replace just the glass unit, not the entire frame and window.
