Condensation and mould fixes for Kensal Green homes
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. Mould needs that damp surface to grow.
Whole-home ventilation
PIV, continuous extract or MVHR where moisture is spread through the house.
Mould treatment advice

Questions from Kensal Green
Do you cover Kensal Green and nearby?
Yes. We cover Kensal Green and nearby places including Willesden, Queen's Park, Harrow Road and Harlesden. 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.
What is the price of a condensation fix in Kensal Green?
Guide prices for Kensal Green use London rates: new ducted fan to outside through the loft or ceiling (insulated duct, roof or soffit outlet) is typically £525 to £900 inc VAT per fan. We confirm a fixed price in writing before any work starts.
