How we handle canopy cleaning in Northfleet Green
Dripping edges and a sticky hood are the first things a visitor notices. What is not seen, behind the filters, tends to be worse. We clean both, so the canopy is clean where it shows and where it doesn’t. The work covers plenum chambers, grease gutters and canopy light fittings, and people most often call us about fat running down the front of the hood and overflowing grease troughs and gutters.
Somewhere as small as Northfleet Green, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Clean the baffle filters often
- Keep grease cups and drawers emptied
- Check filters aren’t leaving gaps
- Report new drips or smells from the canopy
Keep the photo report with your maintenance log, so it’s ready when an EHO, insurer or fire officer asks. Before and after photos speak for themselves.
Tell us if the canopy starts dripping or the filters clog sooner than usual. More drips or quicker clogging often mean the cleaning interval needs looking at, which a grease thickness test can confirm.
Landlords, agents and facilities managers
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Signs you need canopy cleaning in Northfleet Green
A canopy with gaps around its filters lets grease straight through. The plenum and housing behind them then take far more grease than they should, which shows up as heavy deposits when the filters come out.
What we are most often called out for:
- Filters that never seem to stay clean
- Wet, greasy drips from the hood
- Poor capture at the hood
- Drips from the canopy onto the range
Volunteers running a hall kitchen near Church of St Nicholas, or anywhere in Northfleet Green, may not know when the extract was last cleaned, and a grease test settles it.
Questions to ask before you book
- If the quote is a fixed price or an estimate
- Which accreditations they hold, and whether you can check them
- Whether the quote is based on a survey or photos
- When they can work, and whether that’s outside your opening hours
Leave it or put it right?
Grease dripping from the hood can fall onto food, pans and worktops. It’s a food hygiene concern as much as a fire concern, and environmental health officers look at the cleanliness of equipment, extraction included. Rural sites can’t always move to another kitchen or room when something fails.
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.

Northfleet Green kitchens: local notes
Look up Northfleet Green on the FSA’s food hygiene register and you’ll find about 12 restaurants, cafés and works canteens and about 18 takeaways within about 1.5 miles of central Northfleet Green. Any of those kitchens with a canopy has a hood that needs cleaning inside and out. Kitchens in Northfleet Green get their food hygiene inspections from Dartford council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. Northfleet Green is covered by Kent Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Term dates shape school work: for a school like Painters Ash Primary School, an extract clean fits neatly into a half-term or summer break. Healthcare kitchens, like those at hospitals such as Gravesham Community Hospital (about 2.2 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

What else we do in Northfleet Green
What the work involves, part by part
School and staff canteen kitchens
A canteen canopy may cook fewer hours, but it still collects grease. The whole system still needs cleaning at least every 12 months under BESA guidance, and the canopy is part of it.
Plenums and filter housings
The plenum is the space behind the filters where air gathers before entering the duct. Grease that slips past the filters settles there, and it’s cleaned every time we clean the canopy.
Fixed quotes for canopy cleaning in Northfleet Green
Some jobs are bigger than they look, and some smaller. The main factors:
- Site requirements such as sign-in and permits
- Whether it’s a one-off visit or part of a schedule
- What state the system is in
- The size of the system
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before we start.
