Why It's Important to Repair a Broken Window Seal
Condensation on windows that can't be removed with a cloth is a clear indication that the seal on your window has been damaged. This can also cause distortions in the view through the glass and affect the insulation of your home.
While defogging your windows can temporarily solve the problem The best solution is replacing the glass unit that is insulated (IGU). This should be handled by a professional window manufacturer to ensure the replacement is done properly.
Expansion & Contraction
As time passes, the seals on double pane windows wear away because of the expansion and contraction of the spacer that separates the glass. This occurs because of the cycles in temperature that occur throughout the day. As here expands as the sun heats it, the seal is put under pressure. As the glass cools and the window seal shrinks, it expands. The constant contractions and expansions can cause cracks in the seal of the window. This allows humidity in, creating fog between glass panes. The inert gases, like argon that are trapped between the window panes are also released through the crack in the seal. This decreases the insulation properties of the window.
Other indicators of a broken window seal could be visible mold or staining along the edge of a double-pane window. You might also notice an increase in your energy bills or feel drafts near the windows. In this time the window frames may also pull away from the walls or shift. This is a sign you must replace the window seal.
Replacing the seals in a dual pane window is a fairly complex and labor-intensive task that typically involves removing the old seal and the new one, cleaning both of the windows and then replacing the IGU. Although it is possible to perform the IGU replacement yourself however, hiring a professional is highly recommended. Making a mistake during this process could result in drafts, water damage pest infestation and even more costly repairs later on.
A professional can assist you in finding the best repair solution for your situation and offer suggestions on how to keep the seal on your window over time. This could involve a short-term solution, like caulking the gap between the frame of the window and the wall to block insects and water from getting into your home, or it may involve replacing the entire window with a new IGU that is more resistant to weather conditions and seal damage. It could also mean installing an entirely new window that has a different IGU with a higher quality seal or is more suitable for your home's climate.
Weather Conditions
Window seals are designed to withstand harsh weather conditions. However, exposure to constant pressure can cause them to fail. The most frequent causes are extreme temperature changes that cause the glass to expand and contract, placing pressure on the window seal over time. This is particularly true for homes located in areas that experience hot summers and cold winters.
Storms, high humidity and other environmental elements can also damage window seals. Wind, in particular can be very hard on windows which can cause them to move or become loose over time. This can lead to fogging or condensation if air gets trapped between the glass panes. Fogging is not a security issue, but it can make your windows look bad and make them hard to see through.
Additionally, water and humidity can also affect window seals by promoting mold growth or causing rot or corrosion on the frame. If you're experiencing these problems, it's likely that the window seals will need to be replaced.
Another sign that seals on windows are beginning to fail is a rise in energy bills. Heating and cooling systems will be forced to perform more to keep your home cool when the seals on your windows are damaged which can result in higher energy costs for you and your family.
You might be noticing that it's getting harder to open or close your windows. This is an indication that the seals in your windows have become stiff and are not opening or closing correctly. This issue must be addressed before it becomes a major issue, otherwise your windows won't be as energy efficient as they should.
You can extend the life of your window seals by observing the maintenance instructions of the manufacturer. This includes regularly cleaning them with a mild detergent or other approved cleaning agent and ensuring they are free of dirt and other debris. It is also essential to stay clear of using chemical strippers or heat guns on your windows, since they can break the sealant material.
Damage
Unlike the single-pane windows of the past, today's triple-pane and double-pane windows feature glass panes separated by air space. They are then sealed completely around the edges to keep humidity out. The spaces between the glass panels are often filled with inert gases such as Krypton and argon. This reduces the transfer of cold and heat outside the window. These windows are also referred to as Insulated Glass Units (IGUs).
Contact a professional if detect any indications of damaged seals or condensation. They will assess the situation to determine the best way to proceed. If you ignore the issue, it will make the problem worse, leading to higher energy bills and a more obvious impact on the comfort of your home.
Generally, the most affordable option is to replace the IGU and keep the current window frame. This is especially beneficial in the event that the frame is still in good shape and offers more R-value than your original windows and allows you to preserve a large amount of insulating efficiency.
If the frame is damaged, outdated, or has other exterior damage that is in poor condition, you may want to consider a full window replacement for maximum energy efficiency and protection. This type of repair can be done quickly and easily by a professional, enhancing the appearance of your house while making sure that the window's insulation properties are restored.
If your window is under warranty, the manufacturer or installer may be willing to repair or replace the damaged IGU for free. If you are unsure you are, make sure to check the documentation for your window, or contact the installer to see whether it is possible.
Installation
Window seals play a crucial function in keeping drafts out and ensuring energy efficiency in your home. It is not just crucial to repair a damaged seal as soon you notice it, but also to carry out preventative maintenance to avoid any future issues.
Window maintenance is an ongoing process that involves checking regularly for cracks and gaps and then re-caulking if necessary and cleaning. It is recommended to re-caulk the area around your windows once per year to limit the amount of moisture and temperature affects the seals on your windows. This is especially important for older homes that have been shifting since the time of their initial installation.
Regular maintenance of your windows will aid in identifying any issues before they become problematic. This allows you to arrange for a professional to fix your windows as needed. If you notice condensation between your window panes, this is a sign that the frame and glass aren't properly sealed and this can lead to poor indoor air quality. If you hear a tapping sound when you push on your window, it could mean that you should repair the window.
Damage to the frame of the window can also cause the window seal to crack. This can happen when your children or pets accidentally strike a window with a broom, or when harsh cleaning products like paint strippers were used too close to windows. It can also happen if you have aluminum frames that are installed on your windows, which don't offer the same amount of insulation as wood or fiberglass.
A broken seal is best repaired or replaced if your windows are still covered under warranty. This will not only ensure your window is repaired or replaced swiftly however, it could also offer you an opportunity to upgrade to a more energy efficient frame material, such as wood or fiberglass.
If you've got a damaged glass insulated unit, it's usually best to seek out a professional who can replace it. This is the most cost-effective option. It is worth noting, however that many windows come with removable IGUs that contain gas that insulates, allowing you to replace only the glass unit rather than the entire frame.
