What we do, step by step
Every visit runs to the same pattern: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes a few hours for most canopies. For a job in Cranham, tell us about loading bays, permits, lifts and roof access when you book.
- We start by checking the canopy and what’s behind its filters.
- Equipment is turned off and cooled, and the area under the canopy is protected.
- Thick grease is scraped away before the canopy is degreased.
- Plenum, housing, troughs and canopy are all cleaned and checked.
- The canopy is signed off with before and after photos and a next clean date.
Before we arrive
- Have your last certificate or report to hand
- Plan for cooking equipment or plant to be off before we arrive
- Agree a time when the area can be out of use

Advice
Canopy cleaning in Cranham
Canopy cleaning is part of every full TR19® Grease clean, but a canopy can also need cleaning on its own, between full system cleans. Where that’s the case, we will be clear that the ducts and fan aren’t included, so your records stay accurate. We are often asked to deal with drips from the canopy onto the range and wet, greasy drips from the hood, across plenum chambers, island canopies and canopy light fittings.
In London, few kitchens can spare a day to close, so work in Cranham is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Wash or exchange the filters on a regular cycle
- Use non-abrasive cloths on the hood
- Run the extract the whole time you are cooking
- Make sure filters sit tight in the housing
The report gives a recommended next clean date. It reflects how long the kitchen cooks and how much grease we removed, in line with BESA guidance.
Keep the fan running throughout service and for a short while after. Air that keeps moving carries less grease onto the canopy.
Common questions in Cranham
Does London parking affect a job in Cranham?
Tell us where a van can stop near your site in Cranham, and about any building rules on loading. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Can a school canteen extract in Cranham be done out of term time?
Yes, holiday work suits schools best. With about 13 schools and colleges on the FSA’s register within roughly a mile and a half of Cranham, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711, or email photos, and we’ll fit the work in.
How much does canopy cleaning cost in Cranham?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will usually reply within one working day.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Is the inside of the hood cleaned?
We clean the canopy inside and out, including the seams, troughs and gutters. With the filters out, the plenum and housing are cleaned as well.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
What kinds of canopies do you clean?
Wall and island canopies, long cooking-line hoods and small single hoods. Each one is cleaned inside and out, with the plenum behind the filters.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Do you need canopy cleaning in Cranham?
The plenum is hidden behind the filters, so nobody sees it build up. Daily cleaning reaches the canopy face but rarely gets further, leaving the plenum and housing to collect grease between professional cleans.
Common reasons sites call us include:
- Overflowing grease troughs and gutters
- Condensation running down the canopy
- A filter housing caked in grease
- Drips from the canopy onto the range
Healthcare kitchens, like those at hospitals such as St George's Hospital (about 2.4 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.
Before you book anyone
- What insurance they carry
- How they set the interval to the next visit
- Whether a survey comes first
- Whether the whole system is included, or only the parts that are easy to reach
What happens if it’s left?
If the canopy waits for the next full clean, grease keeps adding up. In a busy kitchen, the canopy and plenum can need attention between TR19 cleans, and readings or a look behind the filters will show it. A building in Cranham may have flats or offices above and alongside, and a fault in the system can affect them too.
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.

What else we do in Cranham
Kitchen extracts in Cranham
There are about 82 restaurants, cafés and canteens and about 22 takeaways in Cranham and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Any of those kitchens with a canopy has a hood that needs cleaning inside and out. Kitchens in Cranham get their food hygiene inspections from Havering council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
For kitchens close to Upminster station, where the day often starts early and ends late, the extract can be cleaned overnight. Church and community hall kitchens, near St Luke's Cranham or anywhere around Cranham, are easy to forget, but their extracts collect grease like any other.

Honest limits
Canopy cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Grease in the duct runs and risers behind the canopy
- A hood that doesn’t cover the cooking line
- Electrical faults in the canopy

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
What the work involves, part by part
Pub and hotel kitchens
Few pubs and hotels can shut the kitchen for a day. Canopy cleans are done late at night or early in the morning so the kitchen keeps trading.
Island canopies
Island canopies often have filters on two sides. Both sides are taken apart and cleaned.
