Rules that apply in England

Questions from East Barnet

What is the price of a condensation fix in East Barnet?

Guide prices for East Barnet 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.

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.

Is the survey free in East Barnet?

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.
