COMMERCIAL DUCT CLEANING

Grease, dust and debris can collect inside ductwork far beyond the areas visible from the kitchen. Duct Clean London assesses the route, contamination and safe access before agreeing a practical cleaning scope. Our service is designed for commercial kitchens and selected ventilation systems across London, with clear communication before, during and after the visit.

A kitchen extraction duct may travel above a ceiling, through a vertical riser, across a roof space or along an external wall before reaching the discharge point. Changes in direction and long concealed runs affect how the system can be inspected and cleaned. We start by tracing the known route and reviewing existing access panels. Photographs, drawings and previous cleaning reports are useful. If important sections cannot be reached, we explain whether additional access panels, a mobile tower, roof permission or another safe-access arrangement should be considered.

The service can include removal of accumulated deposits from accessible internal duct surfaces, bends and connected components. Kitchen grease-extract ducts require a different approach from general supply-air or laundry ventilation, so the system type must be identified correctly. We protect nearby equipment and use methods suited to the contamination and duct material. The quotation states the agreed areas and any exclusions. We do not describe inaccessible ductwork as cleaned, and we record sections that remain outstanding so they can be planned properly.

Send the full postcode, operating hours, approximate duct length and photographs showing where the duct leaves the canopy and where it discharges. Tell us about ceiling voids, roof hatches, locked areas, neighbours, parking, loading restrictions and noise limits. Cooking appliances should be cool and the working area must be clear. If the duct passes through a shared building, confirm access with the landlord or managing agent. Good preparation reduces delays and helps the engineers concentrate on the cleaning work during the agreed appointment.

Once the visit is complete, we provide a record of the agreed work with supporting photographs and notes about access limitations. Cleaning removes deposits; it does not correct poor design, replace damaged ductwork or repair mechanical faults. If airflow remains weak after cleaning, the fan, filters, controls or system design may need separate investigation. Future cleaning frequency should reflect the cooking process, hours of use and observed accumulation. We can discuss repeat maintenance for restaurants, cafés, takeaways, hotels and other commercial premises across London.

Commercial ductwork can run horizontally above ceilings, rise through several floors or terminate at roof level, so every quotation should consider the route rather than only the visible grille or canopy connection. Correctly positioned access panels allow internal surfaces to be reached with suitable manual or mechanical cleaning tools. Long runs, sharp bends, fire-rated enclosures and landlord-controlled areas may require additional planning. Before work starts, the site contact should provide drawings if available and explain how ceiling voids, risers, roofs and plant rooms are accessed. Locked doors, fragile roofs, loading restrictions and out-of-hours security arrangements can materially affect the job. Equipment below the work area must be cool and protected, and any required isolations should be agreed with the responsible site personnel. A contractor should not promise complete duct coverage without understanding these conditions. If an internal section cannot be reached safely, the limitation should be photographed and recorded, with a recommendation for additional access rather than hidden behind a general cleaning statement.

Duct cleaning is most useful when it forms part of planned maintenance. The appropriate review period depends on what the system carries, how many hours it operates, the activities taking place below it, filter condition and the rate at which deposits return. A commercial kitchen grease extract is assessed differently from a general supply or extract ventilation system, and laundry ductwork has its own lint and airflow concerns. After the agreed work, records should identify the system, the sections reached, the method used and any remaining limitations. Photographs should show recognisable locations, not unexplained close-ups. If airflow remains poor after deposits are removed, the cause may be a mechanical, electrical or design issue requiring an appropriate ventilation engineer. Cleaning cannot repair damaged ductwork, a failed motor or an undersized fan. Duct Clean London explains these boundaries clearly so clients can plan the correct next action. Send the site postcode, system photographs, operating hours and any previous report for an initial scope review.
