Sealed Window Repair Isn't As Difficult As You Think
Why It's Important to Repair a Broken Window Seal
The presence of condensation on windows that can't be removed is a sign that the seal on your window is damaged. It also affects the insulation ability of your home and can cause distorted views through the glass panes.
Defogging may temporarily solve the issue however the most effective solution is to replace the insulated glass units (IGU). This should be handled by a professional window company to ensure that the replacement is done correctly.
Expansion & Contraction
Seals in dual-pane windows can become damaged in time due to the expansion and contraction of spacers that separate the glass. replace window gasket occurs because of 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 and the window seal shrinks, it expands. These constant expansions and contractions may cause a crack in the seal of the window. This allows humidity to get in the glass, causing fog to form between the panes. The crack in the seal permits inert gases such as argon, which get trapped between window panes to escape. This affects the insulation of the window.
Other indicators of a broken window seal are visible mold or staining along the edges of a double-pane window. You may also notice an increase in your energy bill or feel drafts in the windows. At this point the window frames may also pull away from walls or shift. This is a clear indication that the window seal has to be replaced.
It is a complex and labor-intensive task to replace the seals on a dual paned window. This usually involves removal of the old seal and cleaning the windows and replacing the IGU. Although it is possible to replace the IGU by yourself however, hiring a professional is strongly recommended. This procedure is susceptible to errors that could lead to pest infestation and water damage.
A professional can assist you in finding the most appropriate repair solution to your problem and offer suggestions on how to maintain the seal of your window over time. This could include a short-term fix, such as sealing the gap between the frame of the window and the wall to prevent water and bugs from entering your home, or it may involve replacing the entire window with a new IGU that is more resistant to weather conditions and damage to the seal. You can also install a new window that uses an alternative IGU with more seals or is better suited to the climate of your home.
Weather Conditions
Window seals are made 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 shrink. This puts pressure on the seal over time. This is especially true for homes located in climates which experience hot summers as well as cold winters.
Storms, high humidity and other environmental factors can also affect window seals. Wind, in particular can be extremely hard on windows and cause them to shift or loosen over time. When this happens air can enter the glass panes in an insulating window, causing fogging or condensation. While fogging isn't a safety hazard, it can detract from the appearance of your windows and make them difficult to view through.
In addition, humidity and water can affect window seals by promoting mold growth or causing rot or corrosion on the frame. If you experience these problems you're likely to find that your window seals are in need of replacement.
Another sign that window seals are beginning to fail is a rise in energy bills. Heating and cooling systems will need to be more efficient to keep your home cool if the window seals are broken and will result in higher energy costs for you and your family.
You might also notice it getting more difficult to close or open your windows. This could be a sign that the seal of your window has become stiff, preventing it from opening and closing. It is crucial to fix this issue before it gets out of hand or your windows will not be as efficient in energy as they could be.
Follow the maintenance tips given by the manufacturer to extend the lifespan of the window seals. It is important to wash them regularly using mild detergents or other approved cleaning agents and keep them free of dirt and other debris. It's also important to stay clear of using heat guns or chemical strippers on your windows as they can break the sealant material.
Damage
Contrary to single-pane windows from the past, today's modern double- and triple-pane windows have glass panes separated by air space and then sealed completely around the edges to keep out humidity. The spaces between the glass panels are often filled with inert gasses like Krypton and argon, which minimizes the transfer of heat and cold outside the window. These windows are also known as insulated glass units (IGUs).
If you notice condensation or indications of damaged window seals, it's recommended to consult a professional evaluate the situation and decide the right method of action. If you ignore this issue, it will increase the severity of the issue and will result in higher energy costs and an impact on the comfort of your home.
The most cost-effective option is to replace only the IGU, and keep the frame that you have. This is particularly beneficial if the current frame is still in good shape and offers a higher R-rating than the original windows which allows you to keep an impressive amount of insulation efficiency.
However, if your current frame is in poor condition or has a long-lasting issue and is causing external damage, a complete window replacement might be the best option for maximum energy efficiency and security. This kind repair can be accomplished quickly and easily by a professional, and can improve the appearance of your home and making sure that the window's insulation properties are restored.
If your window is covered by warranty the installer or manufacturer might be willing to replace or repair the damaged IGU for no cost. Check the window's paperwork or contact the original installer to determine whether this is an option in your situation.
Installation
Window seals play an essential 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 perform preventative maintenance to avoid any future issues.
Window maintenance is an ongoing procedure that involves regularly checking for cracks and gaps, re-caulking as needed and cleaning. It is recommended to re-caulk the window area once per year to limit how much temperature and moisture affect the window seals. This is especially important for older homes that have been settling since their original installation.
Regular window maintenance can help you identify any problems before they become an issue. This allows you to arrange for a professional to fix your windows when required. If you notice condensation on the window panes, it's an indication that the frame and glass aren't properly sealed and this can lead to poor indoor air quality. If you hear a tap sound when you press on the window, it could mean that you have to fix the window.
Damage to the frame of the window can also cause the window seal to break. This could happen if your children or pets accidentally smash a window using the broom or cleaning products like paint strippers were used too close to windows. It can also happen if your windows are installed with aluminum frames, which do not provide the same insulation as wood or fiberglass.
If your windows are more recent and still covered by warranty repairs or replacement is usually the best option for a damaged seal. This will ensure that your window is swiftly repaired or replaced, and may also give you the chance to upgrade your window to a more energy efficient frame such as fiberglass or wood.
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's important to note, however that a lot of modern windows feature removable IGUs which contain gas that is used to insulate which allows you to replace just the glass unit instead of the entire frame.
