Questions from Sutton
What area around Sutton do you work in?
All of Greater London. Near Sutton that includes Belmont, Cheam, Carshalton and Banstead.
What is the main cause of condensation in a house?
The main cause is moisture from everyday living, such as showers, cooking and drying clothes, that is not being extracted, combined with cold surfaces where it condenses. Poor or failed extract fans are a very common cause.
Will a dehumidifier fix condensation?
A dehumidifier helps in one room but treats the symptom. Fixing the extract in the wet rooms, and adding whole-home ventilation where needed, removes moisture before it spreads.
