Misted or foggy windows are one of the most common glazing problems homeowners in Cheshunt and the surrounding Hertfordshire towns ask about. If you’re seeing cloudiness between the glass panes, it usually means the sealed unit has failed. That trapped moisture won’t go away on its own and it reduces the insulating performance of the window – so it’s worth fixing.
What causes misting and fog between panes?
Double glazed units (DGUs) rely on a sealed gap, often filled with air or argon, to insulate your home. Over time the seal can fail due to age, thermal stress, or poor installation, letting moisture in between the panes. When that happens you’ll see condensation or clouding. This damages insulation performance and can let insulating gases escape.
Is the whole window frame ruined? Do I need to replace it?
Frequently asked question: “Do I need new windows if my unit is misted?” In most cases, no – the sealed glass unit (the DGU) can be replaced without swapping the whole frame. That keeps costs down and reduces disruption, while restoring clarity and thermal performance.
