Treatments
Condensation treatment
Balanced condensation treatment combining moisture control, airflow and building-fabric observations.
Why diagnosis matters
Treat the cause, then repair the damage
Condensation treatment should match the property. Better extract, controlled background ventilation, heating patterns and attention to cold surfaces may all play a role.

Common questions
About condensation treatment
Will a dehumidifier cure condensation?+
It can reduce humidity while running but does not automatically correct ventilation, heat loss or building defects.
Does anti-mould paint solve it?+
It may delay visible regrowth on a prepared surface, but it does not remove the moisture conditions.
Should windows always be open?+
Ventilation should be controlled and suitable for the property. Constant open windows are not the only strategy.
