Questions from Beckenham

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.
