When people think about duct cleaning, most immediately picture either greasy kitchen extraction systems or dusty air vents. And while those are certainly important, they’re just the tip of the iceberg.

At Lex Hygiene, we go beyond the basics – providing professional cleaning for all types of ductwork. Clean ducts not only improve airflow and efficiency but are also essential for safety, hygiene, and compliance across multiple industries.

Let’s break down the different types of ducting we clean and why each one matters:

Kitchen Grease Extraction Ducts

These are found in commercial kitchens and are responsible for removing heat, smoke, grease, and airborne particles from cooking areas. Over time, grease builds up inside the ductwork, becoming a major fire risk.

🔧 Why clean them?
To comply with fire safety regulations, meet insurance requirements, and ensure a safe working environment.

HVAC & Air Ventilation Ducts

These ducts circulate air throughout buildings – in offices, hospitals, hotels, and more. Over time, dust, mould, bacteria, and allergens can build up, affecting indoor air quality.

🔧 Why clean them?
To maintain healthy air quality, reduce energy bills, and improve system performance.

Industrial Extract Ducts

Factories and industrial sites often have extract systems for fumes, dust, and airborne contaminants generated during production. These ducts can clog quickly depending on the material handled.

🔧 Why clean them?
To keep the work environment safe, comply with COSHH regulations, and ensure machinery runs efficiently.

Chemical Fume Extraction Ducts

Used in labs, processing plants, or cleaning facilities, these duct systems carry harmful or corrosive vapours away from sensitive areas.

🔧 Why clean them?
To protect workers, reduce corrosive damage to ductwork, and maintain environmental safety standards.

Textile or Lint Extraction Ducts

Found in laundries, textile factories, or anywhere with fabric processing, these ducts remove lint, fluff, and fibres – which can easily accumulate and block airflow.

🔧 Why clean them?
To prevent fire hazards, maintain efficiency, and extend the life of equipment.

Office & Commercial Ducting Systems

Often overlooked, standard office and retail spaces use ductwork for heating, cooling, and air circulation. Dust and dirt slowly build up, especially in high-traffic buildings.

🔧 Why clean them?
For healthier indoor environments, better energy efficiency, and compliance with workplace health standards.

Why a quality job matters so much

🔥 1. Fire Safety Isn’t Optional

Especially in kitchen grease ducting, a poor-quality clean means leftover grease — and even small residues can ignite. It only takes one spark or flare-up to trigger a serious fire. A proper, deep clean by professionals removes hidden buildups that a surface-level clean might miss.

🦠 2. Health Risks From Poor Indoor Air Quality

In HVAC systems and air ducts, dust, mould, bacteria, and allergens can circulate through the building if not fully removed. A rushed job or partial clean leaves contaminants behind, affecting staff and customer health — particularly those with asthma, allergies, or weakened immune systems.

🛠️ 3. System Efficiency & Longevity

Duct systems that aren’t properly cleaned will have to work harder to maintain airflow, which drives up energy use and wears out fans, motors, and filters faster. A quality clean improves airflow, reduces strain, and helps avoid costly repairs or premature replacements.

📜 4. Compliance & Documentation

A professional job includes proper documentation — before-and-after photos, detailed reports, and certification that meets insurance and legal requirements. If a job’s not done thoroughly, or no proof is provided, clients could be left uncovered in the event of a fire or inspection.

🧽 5. It’s What You Can’t See That Matters

Ducting runs behind walls, through ceilings, and into hard-to-reach areas. A quick “visual” clean might leave 70% of the contamination untouched. Quality means the right tools, the right access, and the knowledge to clean end to end, not just what’s easy to reach.

Why Choose Lex Hygiene?

• 🔍 Fully certified & compliant cleaning

The Bottom Line: A Cheap Job Could Cost You More

Cutting corners with duct cleaning might save money today — but it increases the risk of:

• Fires or safety violations
• Equipment breakdowns
• Health complaints
• Failing inspections
• Insurance claims being denied
