EXTRACTION FAN CLEANING

Grease can collect on accessible fan blades, impellers and internal housing surfaces, reducing cleanliness and adding strain to the extraction system. Duct Clean London plans fan cleaning around the fan design, location, isolation requirements and safe access. The service can be combined with canopy and duct cleaning so the connected extraction route is considered together.

Extraction fans may be mounted inside the kitchen, above a ceiling, within inline ductwork, on a roof or externally at high level. The location changes the equipment, permissions and time needed for the work. Send clear photographs of the fan housing and surrounding access. Tell us about roof hatches, ladders, locked plant rooms, fragile surfaces, external risers and building-management controls. Where safe access is not already available, a mobile tower, scaffold or other suitable arrangement may need to be discussed before booking.

The agreed service may include removal of grease and dirt from accessible blades, impellers and housing surfaces. The fan must be safely isolated before work begins, and the exact method depends on its construction and condition. Connected filters and ductwork should also be considered because contamination left elsewhere in the route can continue to affect the system. We state what is included in the quotation and record inaccessible internal areas. Components should not be dismantled beyond the agreed cleaning scope without appropriate mechanical support.

Unusual noise, vibration, overheating, electrical faults or poor suction can indicate problems beyond contamination. Worn bearings, loose components, failing motors, damaged controls or an undersized fan require assessment by a competent mechanical or electrical specialist. Cleaning may improve the condition of dirty accessible surfaces, but it cannot guarantee performance or correct poor design. Report all symptoms when requesting a quote. This allows us to separate the cleaning requirement from repair work and avoid promising a result that cleaning alone cannot deliver.

A fan clean is often most useful when planned with the canopy, grease filters and accessible ductwork. We can coordinate the visit around the kitchen’s closing time and discuss evening, overnight or weekend work where suitable. Prepare the cooking area, arrange isolation and provide access permissions before the engineers arrive. After the visit, we supply photographs and a record of the work, including limitations and recommended follow-up. We serve commercial kitchens across North West, West and Central London and welcome enquiries throughout Zones 1–4.

Extraction fans may sit inside a ceiling void, at the end of a horizontal duct, within an external riser or on a roof. Their location determines the access equipment, isolations and working method required. Before cleaning, the fan must be safely isolated by the responsible site personnel and allowed to stop completely. Roof access, fragile surfaces, weather conditions, edge protection and landlord permits may need consideration. Internally, nearby cooking equipment should be off, cool and protected. Grease can collect on blades, inside housings and around connections, but the amount that can be removed depends on whether the casing opens correctly and the components can be reached without unsafe dismantling. If access is inadequate, the report should explain what prevented the work and whether an access panel, specialist equipment or ventilation engineer is required. Honest limitations are safer and more useful than claiming a fan was fully cleaned from a restricted opening.

Removing grease from accessible fan surfaces may support routine maintenance, but it cannot repair worn bearings, damaged blades, loose belts, electrical faults, failed controls or an incorrectly sized fan. Unusual vibration, noise, overheating or persistent poor suction should be referred to a suitable mechanical or electrical specialist. The extract route should also be considered: a clean fan cannot compensate for blocked filters, heavily contaminated ductwork or a restrictive system design. After the visit, photographs and notes should identify the fan location, areas reached and any defects or access limitations observed. Operators should keep this record with the wider extraction-system documentation and review maintenance frequency when kitchen hours, menu or cooking volume change. Duct Clean London can combine accessible fan cleaning with canopy, filter and duct cleaning where the full route is included in the agreed scope. Send clear photographs, the fan location, roof or plant-room details, opening hours and previous reports for an accurate discussion.

Send your postcode, system photographs, opening hours and preferred dates. We will review the information and confirm the appropriate scope before booking.
