Mould has the potential to be harmful to human health and is often a symptom of wider problems within a building. Stroma Built Environment provides a comprehensive mould diagnosis service which can identify the presence of airborne spores and subsequent surface growth. 



Mould has the potential to be harmful to human health and is often a symptom of wider problems within a building. It has been defined as a Category 1 Hazard (the most dangerous) in the Housing Health and Safety Rating System (HHSRS). According to a government report, 3.6% of properties were estimated to have category 1 damp and mould hazards. Mould has gained additional attention during the aftermath of the tragic death of Awaab Ishak due to prolonged exposure to mould. The UK government is in the process of introducing "Awaabs Law" which specifically aims to address the problems of damp and mould in our social housing sector. It places responsibilities on both tenants and landlords to report, cooperate and investigate/remedy any mould issues. 


Where does mould grow?

Mould typically requires warm and damp conditions with poor air circulation to grow. As such, mould can often be found in poorly ventilated areas such as kitchens, bathrooms and utility rooms where people cook, shower and dry clothes. It can also be caused by concealed water or air leakage along with thermal bridging. 

Health Impacts

Exposure to mould can cause the following:

  • Headaches;
  • Dizziness;
  • Coughing;
  • Itchy eyes and dry skin; and
  • Difficulty breathing

Of particular concern, those who are at most risk of health issues are people with pre-existing medical conditions, pregnant women, children, and the elderly.  

How Stroma can help

Whilst mould can grow on almost any surface, using non-destructive diagnostic testing, we can identify the areas most susceptible to mould growth and the root causes of the problem. This is achieved using a wide range of methods to look behind the surface and trace the problem back to the source. Our reports are easy to interpret and can be used as the basis for remedial works. It should be noted that mould must be tackled at the source rather than clearing it away as it will come back again without comprehensive remediation. 

Frequently Asked Questions

How much does a survey cost?

The cost of a survey depends on size of the property and the number of  samples. One of our expert team will be able to provide a proposal.

What does a mould surveyor do?

Unless advised otherwise on particular areas of concern, a Stroma surveyor will use a thermographic camera to identify possible areas of mould growth. From here the technician will then collect physical samples of the area(s) to identify potential mould growth. 

How do you treat mould in a building?

Cleaning the surface will only temporarily improve the situation and will not address the underlying causes of the problem. Areas of mould growth should be remedied by professional teams. We can then undertake a subsequent post remediation survey to demonstrate the issue has been resolved.
