Total Viable Count (TVC) Mould Assessment - Chesterfield

This project focused on understanding the general indoor air quality conditions at a commercial property in Chesterfield, with a particular emphasis on total viable count (TVC) mould levels. The aim wasn’t to overwhelm anyone with data, but rather to get a clear, real-world snapshot of how the indoor environment compared to typical outdoor conditions and whether there were any obvious red flags that needed attention.

Samples were taken from a range of internal areas across the building, alongside an external reference point. This approach helped build a broader picture of what was happening indoors, rather than relying on a single location. By looking at patterns across different rooms and spaces, the assessment was able to highlight how air quality varied throughout the building and where conditions appeared better or worse overall.

What stood out from this project was that indoor mould levels were generally lower than outside, which is usually a reassuring sign. This suggests that the building fabric, ventilation, and general housekeeping measures were doing their job reasonably well. Some internal areas showed more improvement than others, which is quite normal in occupied, multi-use buildings where airflow, usage, and moisture levels can differ from room to room.

The findings were useful not just from a compliance or reassurance point of view, but also as a practical benchmark. Having this kind of TVC mould snapshot allows building managers to understand their “normal” conditions and spot changes early in the future, before they turn into visible mould or occupant complaints. It also provides confidence when making decisions about maintenance priorities, cleaning regimes, or ventilation adjustments.

Overall, the project delivered a clear and accessible overview of TVC mould conditions at the site, helping stakeholders feel more informed and confident about the indoor environment, without getting lost in technical detail or laboratory jargon.
