How we approach condensation and mould fixes in Kenley
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.

Questions from Kenley
Do you cover Kenley and nearby?
Yes. We cover Kenley and nearby places including Purley, Sanderstead, Coulsdon and South Croydon. Send your postcode and we will confirm.
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 black mould dangerous?
Damp and mould can affect health, particularly for people with asthma, allergies, weak immune systems, children and older people, according to NHS and government guidance. It should be dealt with rather than lived with.

Guide prices for Kenley 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.
