Sealed Window Repair: What's New? No One Is Talking About
Why official statement to Repair a Broken Window Seal

Condensation on windows that cannot be cleaned away is a clear sign that the seal of the window has broken. It can also cause distortions in the view through the glass and impact the insulation of your home.

Defogging may temporarily solve the issue, but the best solution is to replace the IGUs (IGU). This is best handled by a reputable window company to ensure the replacement is carried out correctly.


Contraction and Expansion

Seals in dual-pane windows may be damaged over time due to the expansion and contraction of the spacers that separate the glass. This is because of the temperature fluctuations that occur throughout the day. As the glass expands as the sun heats it the seal is put under pressure. As the glass cools at night and the seal around the window contracts. These constant contractions and expansions can result in a break in the window seal permitting humidity to enter the window, creating fog between the glass panes. This crack in the seal can allow inert gases such as the argon gas, which is trapped between window panes to escape. This affects the insulation of the window.

Other indicators of a broken window seal are visible staining or mold along the edges of a double-pane window. You might also notice an increase in your energy bills or feel drafts in the vicinity of the windows. During this time, your window frames could also pull away from the walls or shift. This is a sign that you need to replace the window seal.

Replacing the seals of a dual pane window is a fairly complex and labor-intensive task that typically involves removing the old seal as well as the new one, then cleaning both of the windows and then replacing the IGU. Although it is possible to replace the IGU on your own but hiring a professional strongly recommended. Mistakes during this process can cause drafts, water damage pest infestation and even more expensive repairs later on.

A professional can also help you find the best repair solution for your particular situation and can provide guidance on a long term plan for keeping your window sealed correctly. It could be a temporary fix such as caulking between the window frame, and the wall, to stop bugs and water from entering the home. Or it could involve replacing the entire IGU with a new one that is more resistant against weather conditions and damage to the seal. You can also put in an entirely new window that has an alternative IGU with a better seal or is more suitable for the climate of your home.

Weather Conditions

While window seals are designed to withstand harsh weather conditions, constant exposure to the elements could eventually cause them to fail. Extreme temperature fluctuations can cause the glass within the window to expand and shrink. This can put pressure on the seal over time. This is especially the case for homes in areas where there are hot summers and cold winters.

Window seals are also prone to damage from storms, high humidity and other environmental elements. Wind, in particular, can be particularly tough on windows and cause them to move or loosen over time. This can cause fogging or condensation when air is trapped between the glass panes. While fogging is not an immediate danger but it can affect the appearance of your windows and make them difficult to see through.

Additionally, humidity and water can affect window seals by promoting mold growth or causing corrosion or rot on the frame. If you are experiencing these problems, it's likely that the window seals need to be replaced.

Higher energy bills are another indication that the window seals have begun to fail. If the window seals are damaged the cooling and heating systems will have to perform more efficiently to keep your family members and you comfortably. This could cause higher utility bills.

It could also be becoming harder to open or close your windows. This indicates that the seals in your windows have become stiff and not opening and closing properly. It is essential to address this issue before it gets out of hand and your windows won't be as efficient as they ought to be.

You can extend the lifespan of your window seals by following the maintenance instructions of the manufacturer. It is crucial to wash them regularly using mild detergents or other approved cleaning agents, and keep them free of dirt and debris. Avoid using heat guns or chemical strippers to clean your windows. These can easily cause damage to the sealant.

Damage

Modern double- and triple pane windows are different from the older single-paned windows. They feature glass panes that are separated by air spaces and then sealed around the edges. This keeps the humidity out. The spaces between the glass panels are often filled with inert gases like Krypton and argon, which minimizes the transfer of heat and cold outside the window. These windows are also referred to as Insulated Glass Units (IGUs).

If you spot condensation or other indications of damaged window seals, it's recommended to call a professional to examine the situation and determine the right course of action. Doing nothing will only cause more damage, leading to more energy costs and a more noticeable impact on your home's comfort.

The most cost-effective choice is to just replace the IGU and keep the existing frame. This is especially beneficial in the event that the frame is still in good shape and offers a higher R-rating than your original windows which allows you to keep the majority of your insulation efficiency.

If the frame is damaged or outdated or has any other exterior damage and is in poor condition, you might be considering a full window replacement to ensure maximum energy efficiency and security. A professional can complete this kind of repair easily and quickly, restoring your window's insulating properties, while 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 the window's paperwork or contact the original installer to find out whether this is a possibility in your case.

Installation

Window seals are vital to stop drafts from entering and maintaining energy efficiency in your home. Not only is it vital to repair a damaged seal as soon as you notice it, but also to conduct preventative maintenance to avoid future problems.

Window maintenance is a continuous procedure that involves checking for cracks, gaps and re-caulking as needed and also cleaning. It's recommended that you re-caulk the area around your windows each year in order to limit the amount of temperature and moisture affect the window seals. This is especially important for older homes whose foundations have shifted since their initial installation.

Regular window maintenance can aid in identifying any issues before they become a problem. This lets you plan a repair with a professional your windows when needed. If you notice condensation on the window panes, it's an indication that the frame and glass aren't sealed properly and this can lead to poor indoor air quality. If you hear a tap sound when you push on the window, it could mean that you have to fix the window.

A window seal can also break in the event that the frame of the window is damaged. This could occur when your children or pets accidentally smash a window using a broom, or when harsh cleaning products such as paint strippers were sprayed too close to windows. It can be a problem if you've got aluminum frames on your windows, which don't provide the same insulation as wood or fiberglass.

If your windows are newer and still under warranty Repair or replacement is often the best option for a damaged seal. This will ensure that your window is swiftly repaired or replaced. It could also give you the opportunity to upgrade to a more energy-efficient frame such as wood or fiberglass.

In the case of an insulated glass unit (IGU) which is damaged and requires professional help to replace it is generally the most cost-effective and long-term solution. It's worth noting, though that many windows feature removable IGUs that contain the gas that is used to insulate that allows you to replace just the glass unit, not the entire frame.
