If you've never had a mould or damp assessment before, it's natural to wonder what will happen when the specialist arrives. Understanding the process can help you prepare and get the most value from the visit.
1. Discussion of the problem
The specialist will usually start by asking about the history of the problem — when you first noticed it, which rooms are affected, whether it comes and goes with the seasons, and any events such as leaks or building work. The more detail you can provide, the more accurate the diagnosis.
2. Visual inspection
They will inspect the affected rooms and look for patterns — where the mould is concentrated, whether there are tide marks, water stains, peeling plaster or condensation. They will also look at the outside of the property for defects such as damaged pointing, cracked render, leaking gutters or bridged damp-proof courses.
3. Moisture testing
Using a moisture meter, the specialist will take readings from walls, skirting boards and ceilings to map where moisture is present and how deep it goes. This helps distinguish between surface condensation and deeper damp problems. A hygrometer may be used to measure the temperature and relative humidity in the room.
4. Identifying the cause
Combining the visual evidence and the meter readings, the specialist will form a view on the underlying cause — condensation, penetrating damp, rising damp, a plumbing leak, or a combination. This diagnosis is the most important part of the visit, because it determines the correct treatment.
5. Recommendations and quotation
Finally, you'll receive a clear explanation of what they found and a written recommendation for treatment, along with a no-obligation quotation. A good specialist will explain what work is needed, why, and what it will and won't include, so you can make an informed decision.
How to prepare
- Make sure the specialist can access all affected rooms and the outside of the property.
- Have any photos you've taken ready to show.
- Note down when the problem started and anything that seems to make it better or worse.
- Prepare any questions in advance.
