CANOPY & FILTER CLEANING

The canopy is the most visible part of a kitchen extraction system, but grease can also collect behind the filters and inside the plenum. Duct Clean London provides professional canopy and suitable metal grease-filter cleaning for commercial kitchens. We agree the accessible areas first and can combine the work with duct and fan cleaning when a wider extraction service is required.

Daily kitchen cleaning helps control visible splashes, but it may not reach the internal canopy surfaces, grease channels, filter bank and accessible plenum. Our visit is planned around the construction and condition of your canopy. We identify the areas that can be cleaned safely and protect the surrounding cooking line. The work may include degreasing agreed internal and external surfaces, cleaning grease collection points and removing suitable metal filters for cleaning before they are refitted. The final scope is confirmed before work starts.

Baffle and mesh grease filters are commonly designed to capture airborne grease and may be suitable for professional cleaning. Carbon filters perform a different function and are normally replaced rather than washed as grease filters. Using the wrong filter arrangement can restrict airflow, especially where a small fan has to pull air through unnecessary resistance. Send a clear photograph of the filter bank and tell us the filter quantity and dimensions. We will clarify what can be cleaned and whether replacement filters should be sourced separately.

The kitchen must stop cooking early enough for appliances and canopy surfaces to cool. Equipment below the canopy should be cleared or protected, and engineers must have safe access without standing on hobs, cookers or food-preparation equipment. Tell us about fixed appliances, fragile surfaces and any restricted access before the appointment. We regularly discuss evening and overnight work for restaurants that need to minimise operational disruption. The engineers clean only the areas included in the agreed quotation and record anything that cannot be accessed.

A bright canopy does not confirm that the connected duct and fan are clean. If there is no recent extraction report, ask us to review the wider route. Grease left inside concealed ducts or on fan components may continue to affect maintenance needs. We can plan canopy, filter, accessible duct and fan cleaning as one coordinated visit where suitable. Post-clean photographs and clear notes help kitchen managers understand what was completed, what was excluded and what should be considered before the next maintenance date.

The canopy is the most visible part of a kitchen extraction system, but it is also the entrance to the plenum and downstream ductwork. During planning, we consider the canopy size, cooking line, filter arrangement, access above the filters and the connection into the duct. Reusable metal grease filters can normally be removed, degreased, checked and refitted when they remain serviceable. Disposable carbon filters are not washed and reused; they must be replaced with the correct type where the system has been designed for them. Missing, damaged or poorly fitted filters can allow additional deposits to travel into the plenum and duct. Before the visit, appliances should be switched off, cool and cleared as agreed. Surfaces and equipment that are not part of the work are protected. If the canopy connects to inaccessible ductwork, the limitation must be stated rather than presenting a visible stainless-steel clean as a complete extraction clean. Clear scope protects the customer and makes future maintenance easier to plan.

Heavy staining, grease dripping around filter frames, persistent odours and visible deposits in the plenum are all reasons to review the system, but maintenance should not rely on appearance alone. Some contamination sits beyond the operator’s normal line of sight. Kitchen volume, frying and chargrilling, opening hours, menu changes and daily filter care all influence how quickly grease accumulates. A professional visit should document what was accessible and whether the fan, duct route or discharge requires separate work. It should also note damaged filters, poor fitting, missing access panels or obvious defects that need attention from another trade. Cleaning can remove deposits from reachable surfaces but cannot correct inadequate extraction design or repair faulty equipment. Duct Clean London provides canopy and filter cleaning as a clearly defined service and can also review the wider extract route. For a realistic quotation, send photographs of the complete canopy, filter bank, cooking line, visible duct connection and any existing cleaning report, together with your postcode and preferred working times.

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