Questions from Great Bookham
Do you cover Great Bookham and nearby?
Yes. We cover Great Bookham and nearby places including Leatherhead, Dorking, Ashtead and Cobham. Send your postcode and we will confirm.
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.
