Mould inspection: finding the cause, not just the problem
Seeing mould in your home is unsettling. But visible mould is rarely the whole story. Our professional mould inspection goes beneath the surface to identify exactly where mould is present, what is causing it, and what needs to happen to resolve it properly.

What is a mould inspection?
A mould inspection is a professional investigation of your property to identify the presence of mould, determine the underlying cause, and provide you with clear recommendations for treatment and prevention. Unlike a basic visual check, our inspection uses specialist measuring equipment to assess moisture levels, humidity, air quality and ventilation throughout the property. This gives us a complete picture of what is happening, not just in the areas where mould is visible but throughout the building. The result is a thorough, evidence-based assessment that tells you exactly what you are dealing with and what the most effective solution will be.

Signs you may need a mould inspection
You may need a professional mould inspection if you have noticed any of the following:
Visible mould on walls, ceilings, window frames or behind furniture
A persistent musty smell in one or more rooms
Mould that keeps coming back after you clean it
Black spots appearing around window seals or in bathroom grout
Family members experiencing unexplained allergies or respiratory issues
If you are experiencing unexplained headaches, brain fog, dizziness or persistent allergies at home
What does a mould inspection involve?
Our specialist visits your property and carries out a thorough investigation. We measure moisture levels in the affected areas and surrounding structure, assess humidity and ventilation, and where appropriate take air samples to identify the types and concentrations of mould spores present. We then trace the source of the moisture that is feeding the mould. This is the critical step that most surface treatments skip. Without finding where the moisture is coming from, any treatment will only be temporary. Following the inspection, we provide you with a clear summary of our findings and a recommended course of action. We will explain everything in plain language and make sure you feel confident about the next steps.

No guesswork, no unnecessary treatments, no surprises. We cover Derby, Nottingham, Leicester, Birmingham and the wider Midlands and can usually arrange a visit within a few days.

Landlords: your legal obligations start with a proper inspection
Under Awaab’s Law, social landlords are required to investigate damp and mould hazards within 10 working days of a report. The Renters’ Rights Bill is expected to extend similar obligations to private landlords. A proper professional inspection carried out by a specialist provides documented evidence that you have taken your obligations seriously. Intra Air provides landlords and letting agents with professional mould inspections that include a written report you can keep on file. We work quickly, communicate clearly and make the process as straightforward as possible.
