Ductwork Cleaning in Restaurants and Kitchens
We can rapidly and effectively remove layers of fat, grease, and dust, which pose a major fire hazard inside extraction ductwork.
Why Clean Kitchen Exhaust Ductwork?
Kitchen grease exhaust ductwork becomes heavily fouled with grease, fat, and cooking residue. This creates a severe fire hazard, particularly if cooking oil ignites on a pan or stove. The layer of accumulated debris is highly flammable and burns rapidly. Consequently, regular maintenance and thorough cleaning of both the kitchen hoods and the ductwork are strictly required.
The Contamination Issue
Fat and grease bypass even grease traps and baffle filters inside kitchen hoods, entering the ductwork. Over time, these contaminants often drip back down into the workspace.
Fire Safety
During frying, deep-frying, or flambéing, accumulated debris inside the ductwork can easily ignite, leading to a rapidly spreading fire.
System Performance
Without regular maintenance, the accumulating grease layer can build up all the way to the fan, potentially causing irreversible damage or complete component failure.
Ductwork Cleaning for Extraction Systems
We clean kitchen hood extraction ductwork without dismantling, accessing the system through sealable inspection hatches. The cleaning process combines multiple technologies, typically utilizing food-grade chemical agents that generate an active foam. This foam breaks down contamination on the surface, which is subsequently wiped down or rinsed with a minimal amount of water. We can also deploy dry ice blasting, which proves highly effective for certain critical areas.
Experience
We clean kitchen hood extraction ductwork for prestigious clients, including the Four Seasons Hotel Prague and AIDA cruise ships.
Flexibility
Performing the work outside of kitchen operating hours is a matter of course, including night shifts—ensuring zero disruption for your chefs.
Professionalism
We adhere to all safety regulations and strictly utilize proven, approved technologies and chemical agents.

Westfield Chodov – Prague
In the Westfield Chodov shopping center in Prague, we have set up a preventive plan for inspections and cleaning of ventilation systems, especially for the grease exhausts from the restaurants. Due to the number of business units, this requires large-scale organizing and planning so as not to limit the operation of the shopping center. We also conduct microbiological swap inspections.
