New Zealand's leading
Commercial Ducting
& Hood Cleaning
Service Provider

Keeping the kitchen hood and extractor above cooking appliances—such as stoves, ovens, fryers, and grills—in pristine condition is essential for hygiene and fire safety. This service includes cleaning of oil drains, light fittings, and all areas prone to grease, oil, fat, soot, and dust buildup. A clean extractor hood not only protects your kitchen from fire risks but also safeguards your restaurant’s reputation.​

ComDuc offers a full range of baffle filters (grease filters) compatible with most commercial kitchen hood canopies. Our expert team can exchange, remove, clean, and return your filters on a schedule that suits your needs—weekly, fortnightly, monthly, or customised. We ensure thorough grease removal and help maintain compliance with health and fire safety standards.

​

We provide comprehensive IQP site inspections and 12A certificate sign-off services for kitchen extraction systems, ensuring your building meets the requirements of the Building Warrant of Fitness (BWOF) in compliance with New Zealand’s health, fire, and safety regulations. Our expert team helps you maintain certification and avoid costly penalties.​​​​

A buildup of oil, fat, grease, soot, dust, and debris in your ductwork poses serious health and fire risks by reducing airflow efficiency. These contaminants can also fall back through the hood and filters onto cooking appliances and food surfaces, compromising hygiene. Regular ductwork cleaning ensures your extractor system operates at maximum efficiency and helps maintain a safe, compliant kitchen environment.

Our team provides high-quality cleaning services for laundry duct systems, whether as part of a scheduled maintenance program or one-off jobs. We ensure safe and efficient airflow by removing lint, dust, and debris buildup.
