Canopy cleaning for kitchens and businesses in Harrow Weald
Canopy cleans are done out of hours: after service, overnight or at the weekend. Cooking equipment is turned off and cooled, then covered, and the kitchen is left ready for the next service. Typical jobs include a canopy flagged at an environmental health inspection and condensation running down the canopy, on island canopies, canopy light fittings and baffle filters.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Harrow Weald, that usually means a longer system to clean and more access panels to plan around.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Part by part
Wall canopies
The back of a wall canopy is hard to reach and easy to miss. With the filters out we can get to it and scrape it clean.
Island canopies
Island canopies often have filters on two sides. We work round the canopy, cleaning each filter bank and plenum.
FAQs for Harrow Weald
Which fire service covers Harrow Weald?
London Fire Brigade is the fire and rescue service for Harrow Weald. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can school kitchens in Harrow Weald be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 8 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Harrow Weald. Just ring 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
What happens to the filters during the clean?
We take them out, clean them and put them back. Between cleans, a filter exchange service can keep them in good order.
Do we lose a day’s trading?
Not usually. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
How long does canopy cleaning take?
Allow a few hours, depending on the size of the canopy and how much grease has built up. We will confirm how long when we quote.
Do you have insurance?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
How much does canopy cleaning cost in Harrow Weald?
It depends on the site, so we quote each one individually. For a quote, phone us on 0345 646 2711 or use the quote form with the site type, opening hours and a few pictures.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
What a clean won’t put right
In fairness, some problems need a different fix:
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
- Grease filters too damaged to refit (they need replacing)
- Poor airflow from a fan that needs repair
If in doubt, call us on 0345 646 2711 or use the quote form and we will say what we think before booking.

Fixed quotes for canopy cleaning in Harrow Weald
We don’t publish a price list, because sites vary so much. What we look at:
- The times the site is available
- Any permits to work or inductions
- The scale of the work
- The condition we find in the survey
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.
Asking for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Any access panels or hatches you can see
- Wide pictures of the system and the area around it
- When the site is open and when it’s quiet
- How we’d reach plant on a roof or in a plant room
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Grease, kitchens and Harrow Weald
The FSA’s food hygiene register includes about 15 pubs, bars and clubs within roughly a mile and a half of the centre of Harrow Weald. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Food hygiene inspections in Harrow Weald are the job of Harrow council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after. Most London extract cleaning happens at night, after the last service.
If you run a church or community hall kitchen, near St Michael & All Angels or elsewhere in Harrow Weald, its extract still collects grease from every lunch and event. Bursars and site managers at schools such as Salvatorian Roman Catholic College tend to book extract cleaning for when the kitchen is empty.

Between visits
Aftercare is simple, and it helps at the next visit:
- Leave the extract running until cooking stops
- Keep every filter in place while cooking
- Give the canopy a wipe after service
- Empty the grease troughs before they fill
We clear away the sheeting, waste grease and water before we leave. Every filter is refitted and checked ready for the next service.
A daily wipe of the hood keeps fresh grease from baking on. It doesn’t reach the plenum, but it stops the outside building up.

Managing agents and facilities teams in Harrow Weald
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
The process
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes a few hours, depending on the size of the canopy and how much grease has built up, and we clear up before we go. If your building in Harrow Weald has sign-in rules, permits or key holders, mention them when you book.
- The canopy is checked from photos or on a visit.
- Once the kitchen has closed, the cooking line is cooled and sheeted.
- We lift out the filters and scrape the plenum and housing.
- Inside and out, the hood and its troughs are cleaned.
- We put the filters back, tidy up and photograph the finished canopy.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Make sure someone can let us in and lock up afterwards
- Clear the space around the work
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Related advice
Do you need canopy cleaning in Harrow Weald?
Most canopies have troughs or channels that catch running grease. If they’re not emptied, they fill and overflow, so fat ends up running down the front of the hood.
Clients usually contact us after spotting one of these:
- A hood coated in old grease
- Grease channels that no longer drain
- Filters that never seem to stay clean
- An EHO comment about the canopy
If you cook for passing trade around Headstone Lane station, the extract can be cleaned between your last and first customer.
