Damp and mould removal in Belfast
Get the cause found and fixed, whether it's condensation, rain getting in or rising damp, before the mould is treated.
Almost half of Belfast households rent: 20.5% from private landlords, 16.9% from the Housing Executive and 9.4% from housing associations. For many of them, mould is a repair issue as much as a cleaning job, and knowing who is responsible matters.

Private tenants
Private rented homes in Northern Ireland must meet fitness standards. Properties built before 1945 need a fitness certificate unless an exemption applies. Report mould to your landlord in writing, with photos and dates. If they don't act, contact Belfast City Council's environmental health team.
Housing Rights can advise private tenants and landlords on their rights.
Housing Executive and housing association tenants
Report damp and mould through your landlord's repairs service and keep a record of the reference number. If the problem isn't resolved, use their complaints process.
Diagnosing the cause
A good surveyor checks the outside of the building, the gutters and downpipes, ground levels and pointing, and measures humidity and wall temperatures inside. Condensation is the most common cause in Belfast homes and is fixed by better heating, ventilation and insulation.
Be cautious if a contractor recommends injected damp-proofing based only on a moisture meter reading.
Cleaning and prevention
Clean small areas with a mould remover, following our guide to removing mould from walls. Use extractor fans, open windows after showers and cooking, and keep furniture away from cold outside walls.
If mould returns within weeks of cleaning, the cause hasn't been fixed. That's the point to get a survey rather than cleaning again.
Belfast homes and what they need
Victorian and Edwardian red-brick terraces
Solid brick walls get cold and wet. Check that gutters and downpipes work and that the pointing is sound before treating inside.
Suburban semis
Mould in bedrooms behind wardrobes is usually condensation. Check cavity wall insulation is present and the bathroom fan works.
Apartments in the city centre and riverside
Apartments are often airtight. Drying clothes indoors without ventilation is a common cause, so use a dehumidifier or an extractor.
Areas covered
Engineers who cover Belfast work across areas including Ormeau, Stranmillis, Malone, Ballyhackamore, Sydenham, Andersonstown, Newtownabbey, Holywood, Dundonald and Carryduff.
Questions people in Belfast ask
Can the Affordable Warmth Scheme help with mould?
It funds insulation, ventilation and heating improvements for eligible households, which can reduce condensation. It doesn't cover repairs such as roof or gutter work.
Who pays for a damp survey in a rented Belfast home?
If the damp is a repair issue, the landlord should arrange and pay for investigation. Report it in writing first and ask them to inspect.
Is black mould a health risk?
It can trigger asthma and allergies, and is a particular concern for babies, older people and anyone with a lung condition. Deal with it promptly and fix the cause.
