Questions from Lee
What is the price of a condensation fix in Lee?
Guide prices for Lee 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.
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.
