Persistent smell in your home? We find exactly where it is coming from
A smell that will not go away is almost always a sign of something that needs to be addressed. At Intra Air, we carry out professional odour investigations to identify the precise source of the problem so it can be properly resolved, not just masked.

What is an odour investigation?
An odour investigation is a professional inspection designed to identify the source and cause of persistent or unexplained smells in a property. Rather than using air fresheners or surface treatments that cover the problem temporarily, we trace the smell to its origin. Persistent odours in a home or workplace are commonly caused by mould, damp, poor ventilation, drainage issues, pests, or residual contamination from previous use of the property. Many of these causes are not visible and require specialist equipment and expertise to identify. Our investigation gives you a clear, evidence-based answer about what is causing the smell and what needs to happen to eliminate it for good.
When should you call us?
A smell that has been present for weeks or months with no obvious cause
A smell that gets worse in certain rooms or after rain
A smell that returns after cleaning or using air fresheners
Family members experiencing headaches, nausea or irritation that may be linked to the smell
A smell that started after building work, flooding or a change in the property
You are preparing to sell or let a property and need to resolve a smell before viewings
How does an odour investigation work?
Our specialist visits your property and carries out a systematic investigation to identify the source and cause of the smell. We use specialist equipment to measure air quality, moisture levels and ventilation, and we examine the areas most likely to be contributing to the problem. We do not simply follow our nose. We use data and measurement to build a clear picture of what is happening throughout the property. This approach means we find the actual source, including hidden causes inside walls, floors or structural elements that a visual inspection would miss. Following the investigation, we provide you with a clear explanation of our findings and a recommended course of action.
Why choose Intra Air for odour investigation?
Persistent smells are one of the most frustrating problems a homeowner can face because they are often difficult to locate and easy to mask without actually solving. Our approach is different. We investigate thoroughly, we measure, and we give you a clear answer. We will not recommend treatment until we are confident we have found the cause. And when we do recommend action, it will be targeted at the actual source of the problem, not a general treatment that may or may not work. Covering Derby, Nottingham, Leicester, Birmingham and the wider Midlands.
- Source-first approach, we find the cause before recommending treatment
- Specialist equipment for accurate diagnosis
- Clear explanation of findings with no jargon
Landlords: unresolved smells can affect tenancies and property value
Persistent odours in a rental property can lead to tenant complaints, difficult tenancy renewals and reduced property value. An independent professional investigation establishes the cause on record and enables a targeted, effective treatment. We work with landlords and letting agents across the Midlands to investigate and resolve odour complaints quickly, with written documentation you can keep on file.
Frequently Asked Questions
Yes. Intermittent smells that worsen under certain conditions are often the most informative for diagnosis. Tell us as much as you can about when and where the smell is strongest and we will factor this into our investigation.
In our experience, there is always a source. Some investigations take longer than others and may require follow-up measurements. We will always be transparent with you about what we have found and what further steps may be needed.
No. We can carry out the investigation independently and provide you with findings and recommendations. You are under no obligation to book a treatment with us, though we are happy to provide one if needed.
