What you can do
- Identify whether moisture is inside, outside or between the panes.
- Ventilate briefly and keep air inlets and ventilation grilles clear.
- Observe whether the glass dries and whether walls or corners are also damp.
How to tell whether it helped
Compare similar conditions. Less condensation does not prove a wall is dry; moisture between panes is a different fault.
When to stop
Persistent moisture, mould, wet masonry or mist between panes needs assessment. Do not block ventilation.
How NAPREMO can help
NAPREMO can assess the symptoms and next steps. Glazing or ventilation problems may require the relevant specialist or manufacturer service.
