If you are unable remove condensation from a double-glazed window by opening windows, using extractors, using dehumidifiers or trickle venting, then you might require an expert.
It's rare to see condensation appear on the outside of double glazed windows, however it can occur when the seal between the glass and window frame has started to deteriorate. This is more prevalent in winter as the temperatures are lower and it's more likely for condensation to develop. The most likely cause is a flaw in the spacer that is placed between the window and the frame. This spacer contains desiccant, which is very absorbent and absorbs any moisture that is present.
This could lead to water leaking through the gap once the desiccant has been saturated. This could lead to water and condensation in the gap, which is difficult to get rid of.

Report any problems as soon as possible to your window installer to ensure that the condensation is repaired as quickly as possible to prevent further damage.
