About our canopy cleaning in Greenhill
Duct Doctor has cleaned canopies and hoods since 2009. As a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, we treat the canopy as one part of a whole system, and we hold CHAS, SafeContractor and ISO 9001. Typical jobs include filters that clog soon after cleaning and heavy deposits behind the grease filters, across wall canopies, baffle filters and island canopies.
Kitchens around a place like Greenhill are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
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.

What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What canopy cleaning looks like in Greenhill
Sea air reaches Greenhill, which sits within about 1 mile of the coast. Corrosion on the fan housing and cowl is worth a look at every clean, alongside the grease. Food Standards Agency data counts about 78 cafés, restaurants and staff canteens and about 26 takeaways and sandwich shops within 1.5 miles or so of the middle of Greenhill. Where they cook under a hood, the plenum behind the filters is where grease hides. It’s Canterbury City council that sends environmental health officers to food businesses in Greenhill. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
A hospital like Whitstable and Tankerton Hospital, about 2.4 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Where a hall near St Peter, or anywhere in Greenhill, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

FAQs for Greenhill
Who is the fire and rescue service for Greenhill?
Fire safety enforcement in Greenhill is handled by Kent Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can you clean school kitchen extracts in Greenhill during the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 10 schools and colleges with food registrations within roughly a mile and a half of Greenhill. You can call 0345 646 2711 or use the quote form with the dates the site is empty.
Do you provide pictures of the cleaned canopy?
Before and after pictures go into a report, listing what was cleaned. Where the whole system is cleaned, you also get a TR19 certificate through the BESCA Vent Hygiene Elite portal.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What happens to the filters during the clean?
The filters are removed, cleaned and put back. Each filter is checked for fit as it goes back, because gaps let grease through.
How much does canopy cleaning cost?
It depends on the site, so we quote each one individually. For a quote, give us a ring on 0345 646 2711 or email us and tell us about the site and its opening hours.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
Do you clean canopies in all kinds of kitchens?
We clean canopies in commercial kitchens of every kind. Whatever is cooked under it, the canopy is cleaned the same thorough way, with the equipment off and cool.
Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Use non-abrasive cloths on the hood
- Keep the fan on through service
- Wash or exchange the filters on a regular cycle
- Clean the hood’s outer surfaces daily
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. Turning the fan off early lets vapour settle on the hood.
Do you need canopy cleaning in Greenhill?
Air straight off the range hits the canopy first. Grease from the vapour lands on the canopy’s inner surfaces, its joints and its filters before what gets through reaches the plenum.
Signs it’s time to call us include:
- Heavy deposits behind the grease filters
- Fat running down the front of the hood
- A greasy hood noticed by an inspector
- Overflowing grease troughs and gutters
For schools such as Thornden Wood Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Honest limits
In fairness, some problems need a different fix:
- Electrical faults in the canopy
- Poor airflow from a fan that needs repair
- A dirty extract fan further along the system
If in doubt, call 0345 646 2711, or send details by email and we will say what we think before booking.

Why act early in Greenhill
Drips from a dirty canopy land on the cooking line. That’s a hygiene problem as well as a fire one, and environmental health officers look at the cleanliness of equipment, extraction included. It’s better to plan the work at a site near Greenhill than wait for a failure.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.

The process
A visit follows the same order every time: protect the area, make the system safe, carry out the canopy cleaning, clear away and hand over the paperwork.

- We look at the canopy, filters and troughs first.
- Out of hours, the range is switched off, cooled and covered.
- With the filters removed, the plenum and filter channels are cleaned.
- Inside and out, the hood and its troughs are cleaned.
- Filters are refitted, the area cleaned down and the photo report put together.
Preparing for the visit
- Agree a time when the area can be out of use
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in

Wall canopies
A long wall canopy may hold several sections of filters. Each section’s plenum and housing is cleaned in turn, with photos for each.
Plenums and filter housings
The rails and channels that hold the filters collect grease. Clean housings let the filters seat properly and leave no gaps.
