Why It's Important to Repair a Broken Window Seal
The presence of condensation on windows that cannot be removed is a sign the window seal is damaged. It also affects the insulation capacity of your home and could cause distortion of views through the glass panes.
Defogging may temporarily solve the problem, but the best solution is to replace the IGUs (IGU). A professional window company should handle this to ensure that the replacement is done correctly.
Contraction and Expansion
Seals in dual-pane windows may break down as time passes due to the expansion and contraction of spacers that separate the glass. This occurs because of the temperature fluctuations that occur throughout the day. As the sun heats the glass, it expands, putting pressure on the window seal. At night, as the glass cools and the window seal shrinks, it expands. These constant expansion and contractions can result in a break in the window seal which allows humidity to get into the window, creating fog between the glass panes. The inert gases such as argon that are trapped between the window panes are also released through the crack in the seal. This affects the insulation of the window.
Other signs of a broken window seal could be visible staining or mold on the edges of a double-paned window. You might be noticing a rise in your energy bills or feel drafts around the windows. During this process the window frames could be pulled away or shift from the wall. This is a clear indication that the window seal has to be replaced.
Replacing the seals on a dual pane window is a complicated and labor intensive project that typically involves removing the old seal and the new one, then cleaning both windows, and then replacing the IGU. Although it is possible to perform the IGU replacement yourself but hiring a professional is highly recommended. This procedure is susceptible to errors that can lead to water damage and pest infestation.
A professional will also assist you in determining the best repair solution for your particular situation, and offer suggestions on a long-term strategy for keeping your window sealed correctly. This could include a short-term fix, such as caulking the gap between the frame and the wall to block bugs and water from entering your home, or it may involve replacing the entire window with an IGU that is more resistant to weather conditions and seal damage. It could also involve the installation of the window using a different IGU with a higher quality seal or is better suited to your home's climate.
Weather Conditions
Window seals are made to withstand extreme weather conditions, constant exposure to elements could eventually cause them to fail. The most common causes are extreme temperature variations that can cause the glass to expand and contract, placing pressure on the window seal over time. This is particularly true for homes situated in climates that have hot summers and frigid winters.
Window seals are also susceptible to damage due to high humidity, storms and other environmental conditions. window gaskets replacement can be very hard on windows, causing them to move or become loose over time. This can cause fogging or condensation when air gets trapped between the glass panes. Fogging isn't a safety issue, but it could make your windows look bad and make them hard to see through.
Additionally, humidity and water can also influence window seals by encouraging mold growth or causing rot or corrosion on the frame. If you're experiencing any of these issues, it's likely that your window seals need replacement.
The higher energy bills are a sign that the window seals have started to fail. If the window seals are damaged the cooling and heating systems will need to work harder to keep you and your family at ease. This can cause higher utility bills.
It could also be getting more difficult to shut or open your windows. This is a sign that the seals on your windows have become stiff, and are hindering them from opening and closing correctly. It is crucial to get this problem fixed before it gets out of hand or your windows won't be as efficient as they should be.
You can extend the lifespan of your window seals by following the instructions provided by the manufacturer for maintenance. This includes cleaning them regularly with a mild detergent or other approved cleaning agent and ensuring they are free of dirt and other debris. It's also important to avoid using heat guns or chemical strippers on your windows, as they can break the sealant material.
Damage
Modern double- and triple pane windows are different from the single-paned windows of the past. They feature glass panes that are separated by an air space and then sealed around the edges. This keeps the humidity out. Often, the spaces between the glass panes are filled with an inert gas such as argon or krypton in order to limit the transfer of heat or cold outside the window. These types of windows are also known as Insulated Glass Units (IGUs).
If you notice condensation or other indications of damaged window seals, it's best to contact a professional to assess the situation and determine the right course of action. Doing nothing will only cause more damage and will result in more energy costs and a more visible impact on your home's comfort.
The most cost-effective option is to only replace the IGU and retain the frame you have. This is especially beneficial in the event that the frame is still in good shape and offers a higher R-rating than the windows you originally had and allows you to preserve the majority of your insulation efficiency.
If the frame is damaged, old or has any other exterior damage that is in poor condition, you might be considering a full window replacement to ensure maximum energy efficiency and security. A professional can complete this type of repair easily and quickly to restore your window's insulating properties while also improving the appearance of your home.
If your window is covered by warranty, the manufacturer or installer may be willing to replace or repair the damaged IGU for no cost. Examine the window's documentation or contact the original installer to find out whether this is an option for your particular situation.
Installation
Window seals play an essential role in keeping drafts out and maintaining home energy efficiency. It is not just vital to repair a damaged seal as soon as you spot it, but also to carry out preventative maintenance to avoid any future issues.
Window maintenance is a continuous process that includes regularly checking for gaps and cracks and then re-caulking if required and cleaning. It is recommended to re-caulk the window area every year to limit how much humidity and temperature affect the window seals. This is particularly crucial for older homes whose foundations have shifted since the original installation.
Conducting regular maintenance on your windows can help you spot problems before they develop into an issue with the seal, so you can arrange an appointment with a specialist to make repairs as needed. If you notice condensation on the window panes it could indicate that your frame and glass is not sealed properly. This can lead to poor air quality inside. Additionally, if you hear a sound of tapping when you press your window, it's a sign that the window is sagging and requires repair.
Physical damage to the frame of the window can also cause the window seal to break. This can happen when your pets or children accidentally strike a window with a broom, or when harsh cleaning products, such as paint strippers were sprayed too close to windows. It can also occur if your windows are installed with aluminum frames, which do not provide as much insulative value as fiberglass or wood.
A damaged seal should be replaced or repaired if your windows are still covered under warranty. This will not only ensure your window is repaired or replaced swiftly, but it may also offer you an opportunity to upgrade to a more energy efficient frame material, like wood or fiberglass.
If you have a broken glass insulated unit is usually recommended to hire an expert to replace it. This is the most cost-effective way to go. It's worth noting, though that a lot of modern windows have removable IGUs that contain insulating gas which allows you to replace just the glass unit rather than the entire frame.
