Overview / About mould surveys
What mould surveys involves
Mould needs very little to grow: a surface that stays damp for a day or two and a bit of dust to feed on. A mould survey starts with the growth you can see, maps how far it reaches, and then works backwards to the moisture keeping it alive. That source might be condensation, a slow plumbing leak, rain soaking through a gable or bridged cavity insulation, and each one leads to different work.
It is aimed at families who keep scrubbing the same bedroom corner, landlords answering a tenant's complaint who need written evidence of the cause, and owners who suspect a hidden leak behind fitted units. Book the mould survey at its set price and the specialist will inspect the affected rooms, take readings and set out what is feeding the growth.
What you notice / When mould is telling you something
Living with any of these?
- Black or green patches returning within weeks of being cleaned
- Growth behind wardrobes, beds or sofas pushed against outside walls
- Mildew on shoes, bags or clothes stored in cupboards
- Spotting around window seals, shower trays or bath silicone that spreads
- A stale, earthy smell that stays even after rooms are aired
- Mould appearing in a room with no obvious source of steam
Process / How it works
How mould surveys works with us
Growth mapped
The specialist walks each affected room and notes the location, size and type of visible mould, including hidden spots behind furniture.
Moisture logged
Wall and ceiling surfaces near the growth are tested with meters, and room humidity is recorded alongside surface temperatures.
Source traced
Plumbing, gutters, render, cavity walls and ventilation are inspected to work out whether condensation or water ingress is feeding the mould.
Advice written
You receive photographs, readings and the specialist's recommended steps for removing the cause and treating affected areas.
Four points / on every booking
Four reasons homeowners book across Northern Ireland
- One price, fixed at booking. You see the specialist firm's set price, written down, when you book.
- A report on the moisture. The specialist firm writes up humidity readings, the cause and practical fixes.
- Familiar with local housing. Specialists working in Northern Ireland regularly see wet coastal air and draughty older homes.
- Act on it, or don't. Any ventilation or repair advice is yours to weigh up at your own pace.

Detail / What's involved
Looking beyond the stain
Extent before cause
The specialist records where growth sits and how much there is, including behind furniture and inside cupboards, so the findings show the full picture rather than one patch.
Telling leaks from condensation
Moisture meter readings taken through the depth of the wall help separate surface dampness from water arriving through the structure, which stops money going on the wrong fix.
Written record for rented homes
Landlords and tenants receive the same clear account of where the mould is, what seems to be causing it and what the specialist advises, which helps both sides agree on action.

Answers / Common questions
The short answers

Is black mould in my home a health risk?
Mould spores can irritate breathing, particularly for children, older people and anyone with asthma. The specialist looks at the building, not at health, so if symptoms worry you, speak to your GP as well.
Will cleaning with bleach sort the problem?
Bleach removes the visible staining but does nothing about the damp surface underneath, so growth usually comes back. The survey is about finding and dealing with that moisture.
How much does a mould survey cost?
The price is fixed and shown on the booking page. You pay it when you reserve the visit, and the amount stays the same however many rooms turn out to be affected.
Should I leave the mould in place before the visit?
Ideally, yes. If you need to clean it, take dated photos first so the specialist can see the original spread and position.
