From the outside, many extraction systems appear clean and well-maintained.
Inside, the picture can be very different.
Grease, lint, fibres and airborne debris accumulate over time across a range of environments, including commercial kitchens, care settings, schools and industrial sites.
The risk is rarely dramatic. It builds gradually and quietly.
Before and after images often tell a clearer story than any report. Proper extraction system cleaning is about reducing fire risk and maintaining compliance, not just improving appearance.
