Wet windows and mould
Water on the glass, dark corners, damp wardrobes and black staining on walls or ceilings are frequent signs.
Condensation · Diagnosis and guidance
Condensation
Condensation appears when moisture in the indoor air turns into water on colder surfaces. It often shows up as wet windows, mould in corners, wardrobes, ceilings or bedrooms, together with a heavy indoor atmosphere.
- Wet windows and mould on colder surfaces
- Heavy indoor air, humidity build-up and persistent smells
- Diagnosis helps distinguish condensation from water ingress or rising damp
How to identify it properly
Condensation does not usually begin from the skirting area like rising damp. It tends to appear on colder surfaces, poorly ventilated zones and spaces where indoor air accumulates too much humidity. Mould is one of the most common visible signs.
“It must be water ingress”
Water ingress usually has a more localised external entry point. Condensation is more closely linked to indoor air and cold surfaces.
Air renewal and humidity control
Cleaning mould is not enough. The root issue is often related to indoor humidity build-up and insufficient air renewal.
What usually makes condensation worse
Condensation is often intensified by poor ventilation, showers, cooking, drying clothes indoors, occupancy levels and temperature differences between indoor air and colder surfaces.
Moist indoor air gets trapped
When air is not renewed, indoor humidity builds up and ends up condensing on colder surfaces.
Showers, cooking and clothes drying
Normal daily life produces moisture. If it is not properly evacuated, it often becomes visible as water or mould.
Corners and wardrobes
Less ventilated zones or surfaces with lower temperature are often the first places where the problem becomes visible.
What we do when the issue is condensation
First we confirm that the problem is related to indoor air conditions rather than a localised water entry point. Then we define the appropriate ventilation strategy and the recommended solution, which in this case is EcoPair.
1) Diagnosis
We review mould patterns, ventilation, room use, cold spots, wet windows and the overall behaviour of the indoor environment.
2) EcoPair solution
Controlled indoor air renewal helps reduce excess humidity build-up and improve the overall comfort of the space.
3) Progressive improvement
Over time, the aim is less visible condensation, less mould and healthier indoor air conditions with the right support measures.
Real examples of condensation
Mould in corners, bedrooms, wardrobes and spaces where indoor air renewal plays a key role.
