How It Works
About Ductwork Cleaning
Our comprehensive ductwork cleaning service removes accumulated dust, debris, and microbial growth from your ventilation system, improving indoor air quality and HVAC efficiency.
We use industry-leading techniques including robotic inspection, mechanical brushing, air whipping, and HEPA-filtered vacuum extraction to thoroughly clean all ductwork components.
Each project follows a structured approach: initial video inspection, creation of access points where needed, systematic cleaning, post-cleaning verification, and detailed documentation for compliance purposes.
Service Benefits
- Enhanced indoor air quality
- Improved system efficiency
- Reduced maintenance costs
- Regulatory compliance assured

Ductwork Cleaning FAQs
How often should ductwork be cleaned? ↓
TR19 guidance recommends inspection and cleaning every 1-5 years depending on building usage. Healthcare facilities typically require annual cleaning, while commercial buildings may need cleaning every 3-5 years. We can establish a tailored schedule based on your specific circumstances.
Will cleaning disrupt building operations? ↓
We minimise disruption by scheduling work during off-hours or weekends when possible. For operational buildings, we can section work to maintain partial system functionality. Our equipment is designed to operate quietly and our containment procedures prevent dust from entering occupied spaces.
How do you verify cleaning effectiveness? ↓
We conduct post-cleaning verification through video inspection and deposit thickness testing in accordance with TR19 standards. This includes before-and-after documentation and, if required, laboratory testing of surface samples to confirm removal of microbial contamination.
Can dirty ductwork affect energy consumption? ↓
Yes. Dust accumulation in ductwork can restrict airflow, forcing fans to work harder and consume more energy. Clean ductwork typically improves system efficiency by 5-15%, reducing energy costs while extending equipment lifespan through reduced strain on components.
Is duct cleaning a legal requirement? ↓
Yes. Under the Health & Safety at Work Act 1974 and the Occupiers Liability Act 1984, employers have a legal duty to provide a safe indoor environment. ACOP6 (52) specifically requires mechanical ventilation systems to be "regularly and properly cleaned, tested and maintained to ensure they are kept clean and free from contamination."
