What the work involves
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.
Survey and findings
Humidity and surface readings, existing fans flow-tested, and a written list of causes and fixes.
Fan upgrades
Weak or loft-vented fans replaced and ducted outside, with humidity control.

Questions from World's End

Use the guide price tool, the form on this page, live chat, WhatsApp or call 0800 088 6341. A postcode and a couple of photos help us give you a useful answer first time.
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.
