Why It's Important to Repair a Broken Window Seal
Condensation on windows that can't be removed with a cloth is a clear sign that the seal of the window has broken. It also affects the insulation ability of your home and can cause distorted views through the glass panes.
While defogging windows can temporarily solve the issue, a permanent solution involves replacing the insulated glass unit (IGU). A professional window service will be able to handle this and ensure that the replacement is carried out properly.
Contraction and Expansion
As time passes, the seals on dual pane windows break down due to contraction and expansion of the spacer that separates the glass. This is because of the temperature fluctuations that occur throughout the day. As the sun heats up the glass, it expands putting pressure on the window seal. At night, as the glass cools down, the window seal contracts. These constant expansions and contractions can cause cracks in the seal of the window. This allows humidity to enter and create fog between glass panes. The inert gases like argon that are trapped between panes of glass can also escape through this crack in the seal. This significantly reduces the insulating value of the window.
Other indications of a damaged window seal include visible staining or mold 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 process, your window frames may also shift or pull away from the wall. This is a sign that you must replace the window seal.
It's a difficult and labor-intensive job to replace the seals on a double paned window. This usually involves taking off the old seal, cleaning the windows, and replacing the IGU.

It could also involve installing an entirely new window that has a different IGU that has a better quality seal or is better suitable for your home's climate.
Weather Conditions
Window seals are made to withstand harsh weather conditions. However, exposure to constant pressure can cause them to fail. The most common culprits are extreme temperature fluctuations that cause the glass to expand and contract, placing pressure on the window seal over time. This is particularly true for homes that are located in areas that experience hot summers and cold winters.
Storms, high humidity, and other environmental conditions can also cause damage to window seals. Wind can be particularly rough on windows, causing them to shift with time. In this case, air can infiltrate between the glass panes in an insulating window, causing condensation or fogging. Fogging is not a security issue, but it can make your windows look bad and make them hard to see through.
In addition, humidity and water can cause window seals to degrade by causing rot on the frame or mold growth. If you're experiencing these issues it's likely that your window seals are in need of replacement.
Another common sign that window seals are beginning to fail is a rise in energy bills. If the window seals are damaged the heating and cooling systems will need to perform more efficiently to keep your family and you at ease. This can result in higher utility costs.

Damage
Modern double- and triple pane windows differ from the single-paned windows of the past. They have glass panes separated by an air space, and then completely sealed around the edges. This keeps moisture out. The spaces between the glass panels are usually filled with inert gases such as Krypton and argon. This minimizes the transfer of heat and cold outside the window. These windows are also referred to as insulated glass units (IGUs).
Consult a professional if find any indications of broken seals or condensation. They can evaluate the situation and determine the best course of action. In the absence of this, it can cause more damage which will result in higher energy bills and a decrease in the comfort of your home.
Generally speaking, the cheapest option is to replace the IGU, while preserving the existing window frame. This is particularly beneficial in the event that your current frame is in good condition and has a higher R rating than the original windows. It is possible to keep an impressive amount of insulation efficiency.
If the frame is damaged, outdated or has any other exterior damage and is in poor condition, you might be considering a full window replacement for the highest energy efficiency and security. A professional can carry out this kind of repair easily and quickly and restore your window's insulation properties, while also improving your home's appearance.

Installation
Window seals are vital to stop drafts from entering and maintaining energy efficiency in your home. Not only is it crucial to repair a damaged seal as soon as you notice it but also to perform preventative maintenance to avoid any future problems.
Window maintenance is a constant process that involves checking for cracks, gaps and re-caulking as needed and also cleaning. Re-caulk your window seals once every year to reduce the effects of temperature and moisture. This is especially important for older homes that have been settling since the time of their initial installation.

This could happen if your kids or pets accidentally strike the window with a broom, or if harsh cleaning materials like paint strippers are applied too close to the windows. It can also occur when windows are constructed with aluminum frames, which do not provide the same insulation as wood or fiberglass.
A damaged seal should be repaired or replaced if the windows are still under warranty. This will ensure that your window is swiftly repaired or replaced. It could also give you the chance to upgrade to a more energy efficient frame like fiberglass or wood.
