Why It's Important to Repair a Broken Window Seal
Condensation on windows that cannot be removed with a cloth is an obvious sign that the seal of the window is broken. It can also cause distortions in the view through the glass and impact the insulation of your home.
While defogging windows can temporarily solve the problem The best solution is replacing the insulated glass unit (IGU). This should be handled by a professional window company to ensure that the replacement is done properly.
Expansion and Contraction
Over time, seals in double pane windows wear away due to contraction and expansion of the spacer separating the glass. This is due to the temperature cycles that occur throughout the day. As the glass expands when the sun heats it the seal is placed under pressure. When the glass cools during night the seal on the window shrinks. The constant contractions and expansions could cause cracks in the seal of the window. This allows humidity to get in and create fog between glass panes. The crack in the seal can allow inert gases like argon, which get trapped between window panes, to escape. This decreases the insulation properties of the window.
Other indicators of a broken window seal could be visible staining or mold along the edge of a double-pane window.

Weather Conditions
While window seals are designed to withstand extreme weather conditions, constant exposure to the elements could eventually cause them to fail. The most frequent causes are extreme temperature changes that can cause the glass to expand and contract, placing pressure on the window seal over time. This is especially the case for homes in areas that have hot summers and frigid winters.
Storms, high humidity and other environmental elements can also cause damage to window seals. Wind can be particularly hard on windows, causing them to shift over time. This can cause fogging or condensation if air is trapped between the glass panes. While fogging isn't an immediate danger, it can detract from the appearance of your windows and make them difficult to look through.
In addition, humidity and water can affect window seals by promoting mold growth or causing rot or corrosion on the frame. If you're experiencing these issues, it's likely that your window seals need replacement.

Damage
Modern double- and triple pane windows differ from the single-paned windows of the past. They have glass panes that are separated by an air space and then sealed around the edges. This keeps moisture out. The spaces between the glass panels are usually filled with inert gasses like Krypton and argon, which reduces the transfer of cold and heat outside the window. These windows are also known as insulated glass units (IGUs).
If you notice condensation or other indications of damaged window seals, it's best to consult a professional assess the situation and determine the best way to proceed. If you ignore the issue, it will cause more damage which will result in more energy costs and a more noticeable impact on the comfort of your home.
