What the work involves
A typical family puts several litres of water into the air every day. If extract fans are weak, ducted into the loft or switched off, and windows stay shut in winter, that moisture settles on the coldest surfaces: window reveals, external corners, behind wardrobes and on bathroom ceilings.

How to clean and treat affected areas once the cause is fixed.

Questions from Seaham
What is the price of a condensation fix in Seaham?
Guide prices for Seaham use North East rates: new ducted fan to outside through the loft or ceiling (insulated duct, roof or soffit outlet) is typically £410 to £675 inc VAT per fan. We confirm a fixed price in writing before any work starts.
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.
Is the survey free in Seaham?
For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.
