Why It's Important to Repair a Broken Window Seal
Condensation on windows that can't be wiped away is a clear indication that the window seal has been damaged. It can also cause distortions in the view through the glass and affect the insulation of your home.
While defogging windows can temporarily resolve the issue A permanent solution is replacing the IGU. (IGU). A professional window service should handle this task to ensure that the replacement is done properly.
Contraction and Expansion
Seals in dual-pane windows may become damaged as time passes because of the expansion and contraction of the spacers that separate the glass. This is due to the temperature fluctuations that occur throughout the day. As the glass expands when the sun heats it the seal is put under pressure. As the glass cools it shrinks the window seal. The constant contractions and expansions could cause cracks in the seal of the window. This allows humidity to enter and create fog between glass panes. The crack in the seal allows inert gases, such as argon, which get trapped between window panes to escape. This drastically reduces the insulation value of the window.
Mold or stains along the edges of double-pane windows are also signs of a broken seal. You might also notice an increase in your energy bills or feel drafts around the windows. During this time windows can also pull away from walls or shift. This is a clear indication that the window seal needs to be replaced.
Replacing the seals on windows with dual panes is a fairly complex and labor-intensive project that usually requires the removal of the old seal as well as the new one, then cleaning both windows, and replacing the IGU. While it is possible to replace the IGU by yourself however, hiring a professional is strongly advised. This procedure is susceptible to errors that could lead to pest infestation and water damage.
A professional can help you find the right repair solution for your particular situation and give advice on how to maintain the seal on your window over time. This could be a quick solution, like caulking the gap between the frame and the wall to block insects and water from getting into your home, or it could require replacing the entire window with a brand new IGU that is more resistant to weather conditions and seal damage. You can also install a new window that uses a different IGU with a better seal or is better suited to the climate of your home.
Weather Conditions
Although window seals are constructed to withstand the harshest conditions, prolonged exposure to the elements can eventually cause them to fail. Extreme temperature changes can cause the glass in the window to expand and contract. This can put pressure on the seal over time. This is particularly true for homes in areas that have hot summers and freezing winters.
Window seals can also be subject to damage due to high humidity, storms and other environmental factors. Wind can be particularly hard on windows and cause them to shift over time. This can lead to condensation or fogging when air gets trapped between glass panes. Fogging is not a security issue, but it can make windows appear ugly and make them difficult to see through.
In addition, humidity and water can affect window seals by promoting mold growth or causing corrosion or rot on the frame. If you are experiencing these issues, it is likely that the window seals will need to be replaced.
The higher energy bills are a indicator that the window seals have started to fail. Heating and cooling systems will have to perform more to keep your home comfortable if the window seals are broken and will result in higher energy costs for you and your family.
You might also notice it becoming more difficult to shut or open your windows. This is a sign that the seal on your window has become stiff, which is preventing it from properly opening and closing. This issue must be taken care of before it becomes a major issue, otherwise your windows won't be as energy efficient as they could be.
You can prolong the lifespan of your window seals by observing the maintenance instructions of the manufacturer. This includes cleaning them regularly with mild detergent or an approved cleaning agent and ensuring they are free from dirt and debris. It is also essential to avoid using heat guns or chemical strippers on your windows, since they can break the sealant material.
Damage
Modern triple and double pane windows differ from the older single-paned windows. They feature glass panes separated by air spaces, and then completely sealed around the edges. This keeps moisture out. Often, the spaces between the glass panes are filled with an inert gas, such as Krypton or argon to limit the transfer of cold or heat outside the window. These types of windows are also known as insulated glass units (IGUs).
If you spot condensation or other indications of broken window seals, it's recommended to consult a professional examine the situation and determine the right method of action. If you ignore the issue, it will make the problem worse which will result in increased energy costs and more obvious impact on your home's comfort.
Generally, the most affordable option is to replace your IGU, while preserving the existing window frame. This is especially beneficial when your frame is in good shape and has an higher R rating than the original windows. You can retain an impressive amount of insulation efficiency.
However, if your current frame is in poor shape or is outdated and has other external damage, a complete window replacement could be your best option for maximum energy efficiency and security. This type repair can be completed quickly and easily by a professional, enhancing the appearance of your home while restoring the window's insulation properties.
If your window is still covered by warranty, the manufacturer or installer might be willing to replace or repair the damaged IGU for no cost. If double glazing sealed unit replacement , check the paperwork for your window or contact the installer to see if it is possible.
Installation
Window seals play a vital function in keeping drafts out and ensuring that your home is energy efficient. It's not just important to repair a damaged window seal immediately you notice it, but to also perform preventative maintenance that helps to avoid problems in the future.
Window maintenance is a continuous procedure that involves regularly checking for cracks and gaps and then re-caulking if needed, and cleaning. Re-caulk your window seals at least once each year to limit the effects of moisture and temperature. This is especially crucial for older homes whose foundations have settled since their original installation.
Regular maintenance of your windows will assist in identifying any problems before they become problematic. This allows you to arrange for a professional to fix your windows as needed. If you notice condensation on the windows, it could be a sign that your glass and frame isn't sealed properly. This could lead to poor air quality inside. If you also hear a sound of tapping when you press your window, it's a sign that the window is sagging and needs to be repaired.
A window seal can also break if the frame of the window is damaged. This can happen if your pets or kids accidentally hit the window with a broom, or if harsh cleaning materials such as paint strippers are placed too close to the windows. It can also happen when windows are constructed with aluminum frames, which do not provide as much insulative value as wood or fiberglass.
A damaged seal should be replaced or repaired if your windows are still covered under warranty. This will ensure that your window is quickly repaired or replaced, and could also provide you with the chance to upgrade your window to a more energy-efficient frame such as wood or fiberglass.
If you find an insulated glass unit (IGU) which is damaged and requires professional help to repair it is usually the most cost-effective and long-term solution. It's worth noting, though, that many modern windows come with removable IGUs that contain the gas that is used to insulate which allows you to replace only the glass unit rather than the entire frame and window.
