Discoloration Between Windowpanes: What It Means

It might take a close look, or it may be obvious from across the room. Either way, double-pane window discoloration is a sign your double-pane windows need some attention.

What Could Cause Discoloration in Double-Paned Windows?

The most common cause of discolored windowpane is moisture. While double-pane windows are more energy-efficient than single-pane options, damage or age can compromise the vacuum-sealed space between the panes, allowing moisture to become trapped. Over time, mold can grow between the panes, leading to visible discoloration.

Spot the Difference: What Discoloration Looks Like in Double-Pane Windows

Window discoloration may appear as black streaks or in various other colors, often caused by contact with paint or chemicals in the window frame or window treatments. However, it’s important to note that discoloration is relatively rare in double-pane windows.

Does This Mean There is Mold Between Windowpanes?

Discoloration is usually a sign of moisture or moisture damage, not necessarily mold. However, prolonged moisture buildup between double-pane windows can eventually lead to mold growth. Mold spores can enter the space between the panes and thrive if the window is not repaired or replaced. If you suspect mold in your windows or elsewhere in your home, it’s important to act quickly. The restoration professionals at your local Rainbow International, a Neighborly company, can provide expert mold remediation and removal services to help protect your home.

How to Clean Between Windowpanes

In most cases, a foggy or discolored double-pane window indicates a broken seal. If the discoloration cannot be wiped away from the inside or outside, it’s likely time to replace the window. While some methods exist for cleaning double-pane windows, they can be risky, especially if mold is present. If you notice moisture build up between the panes, it’s best to contact your local Glass Doctor to discuss window replacement options.
