Ductwork cleaning in Cranbrook, Greater London
Ductwork cleaning for commercial sites in Cranbrook and across Greater London. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Readings above 200 microns from a grease thickness test
- A rancid smell from the extract duct
- Duct runs with no cleaning record
Between visits
A little care between visits keeps the system in better shape. We recommend:
- Store the certificate with the fire risk assessment
- Check readings when the menu changes
- Run the extract fan throughout service
- Keep grease filters clean and fitted whenever you cook
You will have a recommended date for the next clean, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Grease that never reaches the duct never needs cleaning out of it. Clean, properly seated filters are the duct’s best protection.
About our ductwork cleaning in Cranbrook
We have been trading since 2009, working across London and the South East. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with each certificate issued through the BESCA portal. The work covers horizontal duct runs, vertical risers and multi-storey ducts, and common reasons people get in touch are high readings at a recent grease test and years of grease along the duct floor.
In London, few kitchens can spare a day to close, so extract cleaning in Cranbrook is usually done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Good records are part of the job. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Cranbrook questions
Which fire and rescue service is responsible for Cranbrook?
It’s London Fire Brigade, which covers Cranbrook. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can the work in Cranbrook be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. It means the site in Cranbrook keeps running as normal. Just ring 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
What shows that the ducts need a clean?
A grease thickness test gives the answer. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and photos.
Do you work in Cranbrook?
Yes. We cover Cranbrook and the rest of Greater London, as part of our work across South East England and London. For a fixed quote, call 0345 646 2711 or send us an email.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes a few hours for a short run, longer for long runs and tall risers, and the area is cleaned down before we leave. Most London sites cannot stop for the day, so work in Cranbrook is typically done overnight, early in the morning or at weekends.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Heavy deposits come out by hand, then each section is degreased.
- We close up, re-test, photograph and record anything out of reach.
How to prepare
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading
Ask for a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Advice
When something else is needed
In fairness, some problems need a different fix:
- Duct sealed behind fixed ceilings or walls
- Leaking duct joints that need repair
- Faulty fire dampers
If you are not sure, just give us a ring on 0345 646 2711 or email us and we’ll give you a straight answer.

What affects the quote in Cranbrook
We don’t publish a price list, because no two systems are the same. What we look at:
- A single visit or a regular plan
- The number of sites or systems
- Travel, parking and unloading
- Whether we need access equipment or extra panels
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before any work starts.
What to send for a quote
Before you ask for a quote, gather:
- Problems your staff have spotted
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site

What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Grease, kitchens and Cranbrook
There are about 292 restaurants, cafés and canteens and about 197 takeaways across Cranbrook and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Behind every canopy among them is a run of ductwork that collects grease out of sight. Cranbrook sits within the area of London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
Volunteers running a hall kitchen near St Clement's Church, or anywhere in Cranbrook, may not know when the extract was last cleaned, and a grease test settles it. For schools such as The Ursuline Academy Ilford, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

Leave it or put it right?
Booking the duct clean in Cranbrook now keeps it a planned job. It takes a few hours for a short run, longer for long runs and tall risers, done out of hours so the kitchen keeps cooking. In Cranbrook, as across London, ductwork often passes through shared risers and other people’s space.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, call 0345 646 2711 or drop us a line for straight advice and a fixed quote.

What we’re called out for in Cranbrook
Ducts in Cranbrook gather grease for the same reasons as ducts anywhere: hours of cooking, the type of food and how well the filters are kept. BESA guidance sets minimum intervals of 3, 6 or 12 months depending on daily use.
Look out for any of the following:
- Duct runs that cannot be reached
- Stale grease odours from the duct
- An insurer asking for TR19 evidence
- Years of grease along the duct floor
Commuter trade near Ilford station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
