How to fix double glazing condensation

Double glazing condensationAre you battling with double glazing condensation and need to know what to do about it? Condensation problems are one of the most common issues faced by Britain’s homeowners – our wet, humid climate is a perfect breeding ground for moisture and water to start creeping onto windows. This may not look like too much of a problem to start with, but left untreated, condensation can lead to black mould, damp patches on walls, peeling wallpaper and an unpleasant musty smell in the home. Condensation can also lead to significant health and breathing problems. For all these reasons, fixing double glazing condensation needs to be a major priority before autumn sets in and the temperature starts to drop.


Why does condensation happen?

Condensation is a process where water vapour turns into liquid once it drops below a certain temperature. So during the autumn and winter, as the temperature plummets at night time the air releases moisture onto windows and walls. This explains why windows can look as if they are streaming in the morning inside the room and why those unappealing black marks start to appear in the corner of windows.

Condensation in double glazing

Double glazing condensationDouble glazing condensation is a common problem as the surface window temperature is colder than the air in the room. It can be caused by too much excess humidity in the home, not enough ventilation or damage to the actual unit. The condensation can appear on the inside faces of the window, the external faces or in the gap between the glazing panes.

It’s the latter that’s often the biggest problem. If the double glazing sealant that secures the glazing has broken, it leaves gaps for moist air to escape into – and once it’s in, there is nowhere for the moisture to go. Once you see the first warning signs of streaming windows, black marks or wallpaper peeling, it’s time to take action.

What can I do about it?

If the double glazing seal has completely failed and you’ve noticed lots of water getting into the glazing, then you may need to look at replacing the entire unit. If this is the case, it’s always worth checking to see if the unit is covered under guarantee.
