Condensation and mould fixes for West Derby homes
A typical family puts several litres of water into the air every day. If extract fans are weak, ducted into the loft or switched off, and windows stay shut in winter, that moisture settles on the coldest surfaces: window reveals, external corners, behind wardrobes and on bathroom ceilings.
Whole-home ventilation
PIV, continuous extract or MVHR where moisture is spread through the house.

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.

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.
