Questions from St Austell
What is the price of a condensation fix in St Austell?
Guide prices for St Austell use South West rates: new ducted fan to outside through the loft or ceiling (insulated duct, roof or soffit outlet) is typically £465 to £775 inc VAT per fan. We confirm a fixed price in writing before any work starts.
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.
