Damp & Mould Assessment or Building Survey: What’s the Difference?
Damp & Mould Assessment or Building Survey: What’s the Difference?
A Damp & Mould assessment can help a landlord understand and document what is happening within a property, but it is not the same thing as a building survey.
With Awaab’s Law now in force in Scotland, landlords and letting agents are understandably paying more attention to how reports of damp and mould are investigated and recorded.
One question that may come up is exactly what a Damp & Mould Assessor does — and where that role stops if a property has a more complicated building defect.
The important distinction is that a Damp & Mould assessment is primarily about investigation, observation and evidence. It gives the landlord a structured record of what was found at the property so they can decide what happens next.
What happens during a Damp & Mould assessment?
An assessment is not simply a case of photographing a patch of mould and writing down where it is.
The property is considered as a whole, with the assessment looking at the conditions that may be contributing to the problem.
This can include the location and extent of visible damp, mould or condensation, how rooms are heated and ventilated, environmental conditions within the property, windows and doors, extract ventilation and relevant accessible building-condition indicators.
Photographs and other observations provide supporting evidence, helping to create a clearer picture of what was present at the time of the visit.
It is about evidence, not guesswork
Damp and mould can have more than one contributing factor.
Condensation and inadequate ventilation may be involved in one property, while another could show signs that point towards water penetration, a building defect, a leak or another source of moisture.
A proper assessment helps move the conversation beyond simply saying that a wall is damp or that mould has appeared.
The aim is to record the evidence clearly, consider the likely causes or contributing factors and provide the landlord or property manager with a factual report.
The landlord still decides what happens next.
The assessment provides information and evidence. The landlord or property manager remains responsible for deciding what repairs, further investigation or specialist involvement may be required.
So how is that different from a building survey?
A Damp & Mould assessment is not an invasive structural or building survey.
The assessor does not open walls, floors or inaccessible parts of the building fabric, and the assessment is not intended to provide a detailed specification for building repairs.
For example, an assessment may find evidence that suggests moisture is entering around a roof, external wall or another part of the building.
That finding can be recorded and highlighted in the report, but investigating the construction in detail and specifying exactly how it should be repaired may require an appropriately qualified building surveyor, roofer, contractor or other specialist.
That does not make the original assessment less useful. In many cases its purpose is to establish what is happening, document the evidence and help the landlord identify the appropriate next step.
Why the distinction matters for landlords
Calling in the right person at the right stage can save time.
A landlord may initially need an independent, documented picture of conditions within the property rather than immediately commissioning an invasive building investigation.
If the assessment identifies something that needs specialist attention, the report can then help the landlord explain what has already been observed and provide a useful starting point for whoever investigates further.
This is particularly relevant now that the investigation and record-keeping around damp and mould has become more important for Scottish landlords.
What does the landlord receive?
Thorn’s Damp & Mould Assessment service follows the Elmhurst assessment methodology and reporting framework.
The finished assessment provides a structured record of the property and occupancy information, room-by-room observations, relevant photographs, ventilation and environmental observations and a clear summary of the findings.
The report is intended to support the landlord or letting agent when deciding what action, repair or further specialist investigation may be appropriate.
What the assessment does not decide
It is also important to be clear about what sits outside the assessor’s role.
The assessment does not determine legal liability between a landlord and tenant, specify detailed remedial building works or replace specialist structural or invasive investigation where that is required.
The purpose is to provide clear property evidence and professional observations so that the landlord can make an informed decision about what happens next.
A useful first step when damp or mould is reported
For landlords and letting agents, that makes a Damp & Mould assessment a useful first step when a concern has been reported but the cause or extent of the problem is not yet clear.
It can establish a documented starting point, identify relevant conditions within the property and show whether further investigation or action should be considered.
