Ventilation is usually the biggest part of the cure, but not the only part. Heating patterns, insulation gaps and cold bridges matter too, and some damp is not condensation at all: leaks, penetrating damp and rising damp need different trades.
Whole-home ventilation
PIV, continuous extract or MVHR where moisture is spread through the house.

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