Questions from Oxted
What is the price of a condensation fix in Oxted?
Guide prices for Oxted use South East rates: new ducted fan to outside through the loft or ceiling (insulated duct, roof or soffit outlet) is typically £490 to £825 inc VAT per fan. We confirm a fixed price in writing before any work starts.
Can you tell if it is rising damp?
We can tell you when the pattern does not look like condensation, such as a tide mark low on a wall or damp that appears after rain, and point you to the right specialist.
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.
