Duct & Air Hygiene
Clean air starts inside the duct.
Dust, debris and biological growth collect inside ductwork, plenums and risers over time and are blown straight back into the occupied space. We remove contamination at the source — brushing, compressed-air agitation and HEPA vacuuming — then treat surfaces with anti-microbial products that help resist regrowth of bacteria, fungi and mould.
Healthier occupants
Removes the dust and microbial load that drives allergies, odours and sick-building complaints.
Better airflow
Clean ducts, coils and diffusers restore design airflow and reduce fan energy.
Documented compliance
Photo and video evidence for every run supports audits, accreditation and insurance.

How we work
Our process
- 01
Inspect
CCTV and visual inspection records the baseline condition of each run.
- 02
Protect & isolate
Units are isolated, floors and furniture protected, and the work area sealed.
- 03
Agitate & extract
Rotary brushes and compressed air dislodge debris under HEPA-filtered negative air.
- 04
Treat
An anti-microbial treatment is applied to duct and plenum surfaces to resist microbial regrowth.
- 05
Close-out & verify
Panels are sealed, systems restarted and the after condition is recorded.

Robotic Duct Cleaning
Our in-house camera robot and drill-driven rotary brushes reach duct runs and risers no person can enter — cleaning and filming as they go.
CCTV & Visual Inspection
Camera and borescope surveys of ductwork, plenums and units — so you clean, repair or replace only what needs it.
