Diagnosis
A structural damp problem is solved by extracting humid air where it arises. Targeted mechanical extraction in bathroom, kitchen and toilet keeps humidity healthy.
Take the ventilation check
Ventilation against damp
Damp in the home shows as condensation, clammy walls, a musty smell and eventually mould. Ventilation tackles the cause, humid air that lingers.
The right approach
A system C or C+ continuously extracts humid air from the rooms where moisture arises. Note: structural damp (rising or penetrating) needs a separate approach alongside ventilation.
Indoor air
What healthy indoor air means
Ventilation is about invisible air quality. Here is how to recognise healthy values.
CO2ppm
good: below 800attention: above 1200
High CO2 makes rooms stuffy and tiring, often in bedrooms.
Relative humidity%
good: 40 to 60attention: above 70
