Misty, cloudy or fogged double glazing can make otherwise perfectly good windows and doors look tired and obstruct your view outside. If condensation has appeared between the panes of glass, it usually indicates that the sealed glass unit has failed – but that doesn’t necessarily mean the complete window or door needs replacing.
Window Doctor provides professional misty glass replacements through our nationwide network of local branches, working with double and triple glazed windows and doors in residential and commercial properties.
Our experienced glaziers can identify failed sealed units and replace the affected glazing while retaining the existing uPVC, aluminium or timber frame wherever it remains serviceable. This allows the underlying problem to be addressed without unnecessarily replacing the complete window or door.

Common Reasons For Misty or Cloudy Glass:
Double and triple glazed units are manufactured as sealed units, with separate panes of glass enclosing a sealed space between them. If the seal around the unit deteriorates or fails, moisture can enter this space and become visible as misting, condensation or cloudiness between the panes.
Common signs and causes of failed glazing include:
- Condensation between the panes – one of the clearest signs that a sealed glass unit has failed.
- Misty or foggy glass – moisture inside the unit can create a hazy appearance that comes and goes or becomes progressively worse.
- Cloudy double glazing – failed units can lose their original clear appearance and become difficult to see through.
- Failed perimeter seals – deterioration around the edge of the sealed unit can allow moisture to enter.
- Age and general deterioration – sealed units can gradually deteriorate after years of exposure to changing temperatures and weather.
- Poorly manufactured or installed units – problems with the original glazing unit or installation can contribute to premature failure.
- Water droplets between the panes – more advanced failure can result in clearly visible moisture accumulating inside the unit.
- Permanent staining or marks inside the unit – repeated moisture ingress can eventually leave deposits that cannot be cleaned from either external surface.
It’s important to distinguish condensation between the panes from condensation on the inside or outside surface of the window. Surface condensation can occur for entirely different reasons and doesn’t automatically mean the sealed glass unit has failed. If the moisture or cloudiness cannot be wiped away from either accessible side of the glass, however, it is likely to be inside the sealed unit.

Frequently Asked Questions - FAQs
Why is there condensation between my double glazing?
Condensation between the panes usually indicates that the seal around the double glazed unit has failed, allowing moisture into the sealed space between the glass. The affected unit will generally need replacing to restore clear glazing.
Can you repair misted double glazing without replacing the whole window?
Yes. If the surrounding frame remains serviceable, the failed sealed glass unit can often be replaced independently. This allows you to retain the existing window or door rather than replacing the complete installation.
Can misted double glazing be cleaned from the inside?
Not in the same way as ordinary surface condensation. If moisture is trapped between the panes of a sealed unit, you cannot access it simply by cleaning the inside or outside surfaces of the window. Replacing the failed sealed unit provides a long-term solution.
Is condensation on the inside of my windows the same as misted double glazing?
No. Condensation on the accessible room-side surface of the glass can be associated with humidity and ventilation within the property. Misted double glazing refers specifically to moisture, fogging or cloudiness between the panes of a sealed glass unit.
Can you replace misted glass in doors as well as windows?
Yes. Window Doctor can replace suitable failed double and triple glazed units in both windows and glazed doors, provided the surrounding installation remains suitable for retaining.
