Window Condensation Problems in Mandeville, LA: Causes and Fixes

What Condensation On Windows Is Really Telling You

When people talk about foggy windows, they are often describing two very different issues, and the fix depends on where the moisture is showing up.

Interior sweat usually points to a humidity and temperature mismatch, not a broken window right away.

Condensation between the panes is a different story. That almost always means the seal has failed, and once outside air and moisture get into the spacer cavity, cleaning will not solve it.

In a coastal climate like Mandeville, the line between those two problems matters because humidity stays high for long stretches of the year.

When The Glass, Frame, Or Installation Is The Real Issue

If the moisture is only on the inside of the glass and clears when indoor conditions improve, you may be looking at a house humidity issue rather than a product failure.
