10 Misconceptions That Your Boss May Have Regarding 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 seal on your window is damaged. It can also cause distortions in the view through the glass and affect the insulation of your home.
While defogging windows can temporarily solve the issue A permanent solution is replacing the IGU. (IGU). This should be handled by a professional window company to ensure that the replacement is carried out correctly.
Contraction and expansion
Seals in dual-pane windows may become damaged in time due to the expansion and contraction of spacers that separate the glass. This occurs because of the cycles in temperature that occur throughout the day. When the sun warms the glass, it expands putting pressure on the window seal. As the glass cools at night the seal on the window contracts. The constant contractions and expansions could cause cracks in the seal of the window. This allows humidity to enter, creating fog between glass panes. The inert gases such as argon that are trapped between panes of windows are also released through the crack in the seal. This decreases the insulation properties of the window.
The presence of stains or mold on the edges of double-pane windows are other indications of a damaged seal. You may also notice an increase in your energy bills or feel drafts near the windows. In this process, your window frames may also shift or pull away from the wall. This is a clear indication that the window seal has to be replaced.
Replacing the seals in windows with dual panes is a complex and labor-intensive task that typically requires removing both the old seal and the new one, and then cleaning both windows and then replacing the IGU. While it is possible to replace the IGU by yourself but hiring a professional highly advised. Incorrect decisions during this process could lead to water damage, drafts, pest infestation and even more costly repairs later.
A professional can help you find the best repair solution for your particular situation and provide advice on how to maintain the seal of your window over time. It could be a temporary fix such as caulking the window frame, and the wall, in order to prevent the entry of water and bugs into the home. Or, it could mean replacing the entire IGU with a brand new one that is more resistant against weather conditions and damage to the seal. You could also install an entirely new window that has a different IGU with a better seal or is more suitable for the climate of your home.
Weather Conditions
Although window seals are constructed to withstand the harshest weather conditions, constant exposure to the elements could eventually cause them to fail. Extreme temperature changes can cause the glass within the window to expand and contract. This causes pressure on the seal over time. This is particularly true for houses that are situated in areas with hot summers and cold winters.
Storms, high humidity and other environmental conditions can also cause damage to window seals. Wind can be particularly hard on windows and cause them to shift with time. When this happens air can enter the glass panes of an insulation window, which can cause condensation or fogging. Fogging is not a safety issue, but it could make your windows look bad and make them hard to see through.
The humidity and water can cause window seals to degrade through causing rot to the frame or growth of mold. If you're experiencing these issues, it's likely that your window seals need replacement.
The higher energy bills are a sign that the window seals are beginning to fail. If the window seals are damaged then your cooling and heating systems will need to work harder to keep your family and you comfortable. This will result in higher utility costs.
You might also notice it becoming harder to shut or open your windows. This is a sign that the seals on your windows have become stiff and are not opening or closing properly. This problem must be dealt with before it becomes a major issue, otherwise your windows won't be as energy efficient as they ought to be.
You can prolong the life of your window seals by following the manufacturer's instructions for maintenance. It is essential to regularly clean them using mild detergents or other approved cleaning agents, and to keep them free of debris and dirt. It is also crucial to avoid using heat guns or chemical strippers on your windows, as these can easily break the sealant material.
Damage
Modern double- and triple pane windows differ from the older single-paned windows. They have glass panes that are separated by an air space and then sealed around the edges. This keeps humidity out. The spaces between the glass panels are often filled with inert gasses like Krypton and argon. This reduces the transfer of heat and cold outside the window. These kinds of windows are also known as IGUs, or insulated glass units (IGUs).
Call a professional if you find any indications of broken seals or condensation. They will assess the situation and 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 your home's comfort.
The most cost-effective choice is to only replace the IGU and keep the existing frame. This is especially advantageous when the frame you have is still in good shape and offers more R-value than your original windows which allows you to keep a large amount of insulating efficiency.

If the frame is in a poor state or is outdated and has other exterior damage, full window replacement could be your most effective option for optimal energy efficiency and security. A professional can perform this kind of repair easily and quickly to restore your window's insulating properties and also improving the appearance of your home.
If your window is under warranty, a manufacturer or installer may be willing to repair or replace the damaged IGU for free. Check replacement sealed units for double glazed windows or contact the original installer to find out whether this is a possibility in your situation.
Installation
Window seals play an essential role in keeping drafts away and ensuring energy efficiency in your home. It is not just important to fix a broken seal as soon as you notice it, but also to conduct preventative maintenance to avoid any future issues.
Window maintenance is a continuous process that involves examining for cracks, gaps, and re-caulking if necessary and also cleaning. Re-caulk your window seals at least once every year to reduce the effects of temperature and moisture. This is particularly critical for older homes that have been shifting since the initial installation.
Regular maintenance of your windows will assist in identifying any problems before they become a problem. This allows you to schedule a professional to repair your windows when required. If you notice condensation between the window panes, it could be a sign that your glass and frame is not sealed properly. This could lead to poor indoor air quality. If you hear a thumping sound when you press your window, it could mean that you should repair the window.
Physical damage to the frame of a window could also cause the window seal to crack. This can happen if your kids or pets accidentally smash the window with a broom or if harsh cleaning substances like paint strippers are sprayed too close to windows. It could also happen if your windows are installed with aluminum frames, which don't offer the same insulation like fiberglass or wood.
If your windows are more recent and still covered by warranty repairs or replacement is often the most appropriate option for a damaged seal. This will not only ensure that your window is replaced or repaired quickly, but it may also give you the chance to upgrade to a more energy efficient frame material, like wood or fiberglass.
If you have a broken insulated glass unit, it's usually best to seek out an expert to replace it. This is the most cost-effective solution. It's important to note, however that many windows have removable IGUs that contain gas that is used to insulate, allowing you to replace only the glass unit, not the entire frame and window.
