Poor Indoor Air Quality Is More Common Than You Think
Most people assume the air inside their home is fine. But mould spores, allergens, pollutants and poor ventilation can build up silently and can affect your health over time. Our indoor air quality assessment gives you a clear picture of what is in your air and exactly what needs to change.

What is an Indoor Air Quality Assessment?
An indoor air quality assessment is a thorough, professional inspection of the air inside your property. Using specialist measuring equipment, our experts analyse a wide range of factors that can affect the health and comfort of the people living or working in the building. We measure moisture levels, humidity, CO2 concentrations, mould spore presence, ventilation effectiveness and other environmental factors. Based on our findings, we provide you with a clear written report and practical recommendations for improving your indoor environment. This is not a visual inspection. It is a data-driven, evidence-based service that gives you an accurate picture of what is actually happening inside your home, not just what you can see.

Signs you might need an assessment
You do not need to have visible mould or damp to benefit from an indoor air quality assessment. Many air quality issues are invisible. Here are some signs your home may have a problem:
Recurring condensation on windows or walls
Persistent musty or stale smells with no obvious cause
Family members experiencing unexplained respiratory symptoms, headaches or allergies
A property that has recently had flooding, water damage or building work
A home that feels stuffy or uncomfortable despite adequate heating
You want peace of mind that your home environment is genuinely healthy
What does the assessment involve?
Our specialist visits your property and carries out a comprehensive measurement of your indoor environment. This typically takes between two and three hours. We use professional equipment to measure: Moisture levels in walls, floors and ceilings. Relative humidity throughout the property. CO2 levels as an indicator of ventilation quality. Mould spore concentrations in the air. Temperature differentials that can indicate condensation risk. Following the visit, we produce a clear written report summarising our findings, explaining what they mean in plain language, and setting out the recommended next steps. We walk you through the report and make sure you understand exactly what is happening and what to do about it.

Landlords and Property Managers
Indoor air quality assessments are increasingly relevant for landlords under the Homes (Fitness for Human Habitation) Act and the emerging obligations under Awaab’s Law. If tenants are reporting health concerns, respiratory issues or persistent odours, an independent professional assessment provides you with documented evidence of the property’s condition and demonstrates that you have taken your obligations seriously. We work with letting agents and landlords across the Midlands to provide fast, professional assessments with full written reports you can keep on file.
Frequently Asked Questions
Most assessments take between two and three hours depending on the size of the property. We will give you a clear timeframe when you book.
No special preparation is needed. Just ensure we can access all rooms including any loft spaces or basements where relevant. It helps if windows have been closed for a few hours beforehand to give us an accurate reading of the indoor environment.
Yes. Every assessment includes a clear written report summarising our findings and recommendations. We will talk you through it at the end of the visit and follow up if you have any questions afterwards.
