About our extract fan cleaning in Canons Park
Cleaning removes grease, not wear. If we find worn bearings, a struggling motor or damage to the impeller, we will tell you, and we also repair and replace extract fans. You get an honest view of the fan’s condition. The work covers roof-mounted fans, axial fans and fan housings, and common reasons people get in touch are an extract fan with no cleaning record and a fan motor running hot under a coat of grease.
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 Canons Park, that normally means a longer system to clean and more access panels to plan around.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What we’re called out for in Canons Park
By the time air reaches the fan, it has passed the canopy, filters and duct. Whatever grease is still in it settles on the impeller and inside the housing where the spinning blades spread it around.
Look out for any of the following:
- A fan that has never been cleaned
- A smell of hot grease from the extract
- A noisy fan that has got louder over time
- Vibration from an unbalanced impeller
Term dates shape school work: for a school like Camrose Primary With Nursery, an extract clean fits neatly into a half-term or summer break.
What to look for in a quote
- Whether the whole system is included, or only the parts that are easy to reach

Why act early in Canons Park
Grease on a roof fan can also escape outside. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. Choosing the date yourself beats having a fault choose it for you.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.

Your questions about extract fan cleaning in Canons Park
Which fire service covers Canons Park?
It’s London Fire Brigade, which covers Canons Park. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you clean school canteen extracts around Canons Park out of term?
Yes. The holidays are the usual time for school work. With about 23 schools and colleges on the FSA’s register within roughly a mile and a half of Canons Park, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Is Canons Park in your area?
Yes. We cover Canons Park and the rest of Greater London, as part of our work across South East England and London. For a fixed quote, ring 0345 646 2711 or send us an email.
Do you work out of hours?
Yes. Evenings, nights and weekends are normal working hours for us, so you don’t have to close during trading.
What paperwork do I get after a fan clean?
A photo report, including the fan’s condition and the next clean date. Keep it with your maintenance log.
Will we have to shut during the visit?
Not normally. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.
Do you have insurance?
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. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
The process
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes an hour or two for one fan, longer when it’s hard to reach. If your building in Canons Park has sign-in rules, permits or key holders, mention them when you book.
- First we locate the fan and agree how it’s safely isolated.
- Power to the fan is isolated before anyone touches it.
- We remove the grease from the blades, impeller and casing.
- Blades, housing and the area around the motor are degreased with care.
- It’s closed up, run and checked, and photos go into your report.
How to prepare
- Find the previous report, if there is one
- Arrange a key holder or contact on site
- Let us know when the site is closed or quiet
How to get a quote
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before work begins.
Advice
How the job changes from site to site
Kitchens with long cooking hours
A fan in a long-hours kitchen runs for most of the day, which means grease and wear add up quickly. Regular cleans help it keep going.
Fan housings and motors
We clean around the motor without soaking its electrics, and the fan is isolated throughout. Grease around the motor can make it run hotter, so the surrounding area is cleaned carefully.
What affects the cost of extract fan cleaning
You’ll get a fixed price before any work starts. It takes into account:
- How big the system is
- The number of sites or systems
- Site rules, permits and inductions
- One-off work versus a regular cycle
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before work begins.
Asking for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
- The postcode and the type of business
- A few general shots of the system
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To start, call 0345 646 2711 or use the quote form.

What else we do in Canons Park
Extract fan cleaning around Canons Park
Look up Canons Park on the FSA’s food hygiene register and you’ll find about 184 cafés, restaurants and staff canteens and about 77 sandwich bars and takeaways across Canons Park and its immediate surroundings (about a mile and a half). Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Most London extract cleaning happens at night, after the last service. Kitchens in Canons Park get their food hygiene inspections from Harrow council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready.
Volunteers running a hall kitchen near Church of St Lawrence, or anywhere in Canons Park, may not know when the extract was last cleaned, and a grease test settles it. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Edgware Community Hospital is the nearest hospital to Canons Park, about 0.8 miles east.

Managing agents and facilities teams in Canons Park
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
What a clean won’t put right
Before you book, it helps to know what’s not included:
- An undersized fan that can’t cope
- Wiring faults to the fan
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think before you book.
