Discoloration Between Windowpanes: What It Means

Wiping the stains of the window.

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.

Read on to learn what causes this discoloration, how you can prevent it, and how to deal with the issue before it leads to bigger problems.

What Could Cause Discoloration in Double-Paned Windows?

The most common cause of a discolored windowpane is moisture. Double-pane windows are more energy-efficient than single-pane alternatives, but if the window is damaged or old, the vacuum-sealed gap between the panes of glass can trap moisture. The resulting mold growing between your windowpanes then causes discoloration.

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

Window discoloration can appear as black streaks across the window or various other colors due to contact with paint or other chemicals in the window frame or window treatments. However, it's worth noting that discoloration is rare in double-pane windows.

Does This Mean There's Mold Between Windowpanes?

The discoloration is usually a sign of moisture or moisture damage, not necessarily mold. However, high moisture between double-pane windows can eventually lead to the development of mold. Mold spores can find their way into the gap between window panes and grow if the window is not repaired or replaced. If you believe you already have mold in your windows or elsewhere in your home, it's important to act quickly to have it removed. The restoration pros at your local Rainbow International, a Neighborly company, can help with expert mold remediation and removal services.

How to Clean Between Windowpanes

In most cases, a double-pane window that's foggy or discolored is already broken. If you can't wipe it clean from the inside or outside, it may be time to replace your window.

Although there are ways to clean a double-pane window, it can be risky if you're dealing with mold. If you notice a buildup of moisture in your double-pane windows, we recommend contacting your local Glass Doctor about a window replacement.
