Part by part
The plenum
Clean filters reduce the grease reaching the plenum, but it still needs cleaning as part of TR19.
Canopy filter housings
The filter housing holds each filter at an angle in the canopy. A damaged housing leaves gaps.
Grease filter exchange in St Mary's Bay, done properly
Think of filter exchange as routine care for the extract. It keeps airflow up and grease down between full cleans and takes a messy task off your team. The full TR19 clean then gives the system its clean bill of health. We are often asked to deal with hand-washed filters that still look greasy and filter washing that keeps being missed, on restaurants and pubs, island canopies and baffle filters.
For a smaller kitchen near St Mary's Bay, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

How we price grease filter exchange
Every site gets its own quote. This is what makes a difference:
- Whether it’s a one-off visit or part of a schedule
- How easy every part is to reach
- The scale of the work
- Parking and loading at the site
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.
What we need to know
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The roof, plant room or outside wall the system runs to
- When the site is open and when it’s quiet
- Wide pictures of the system and the area around it
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, phone us on 0345 646 2711 or use the quote form.
FAQs for St Mary's Bay
Can the work in St Mary's Bay be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in St Mary's Bay needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Who carries out food hygiene inspections in St Mary's Bay?
Kitchens in St Mary's Bay are inspected by Folkestone and Hythe council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Which records should we keep?
Everything that shows the system is looked after: our reports and photos, any certificates and your in-house logs. A single log for each site works best.
Do you clean filters as well as exchanging them?
We can. Cleaning your existing filters is an option, and others prefer a straight swap. We make sure the canopy is ready for service either way.
Which grease filters does the service cover?
Both baffle filters and mesh filters are covered. At the start, we note what your canopies use so every set we bring fits.
Do we lose a day’s trading?
Not normally. We need the work area to ourselves while we are on site, so we book a time when it would be closed anyway.
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Keep canopy surfaces wiped down
- Report damaged filters so they can be replaced
- Report a dripping canopy early
- Make sure we can reach the canopy on exchange day
Fresh filters improve airflow at the canopy straight away. Always run the extract during cooking so they catch grease as intended.
Bent or missing filters let grease straight past. Replacing them early protects the plenum and ductwork.
Grease filter exchange in St Mary's Bay: the local picture
At about 1 mile from the coast, St Mary's Bay is close enough for sea air to matter. Salt air speeds up corrosion of roof-level fans, discharge cowls and their fixings. Food Standards Agency records list about 11 restaurants, cafés and works canteens and about 4 takeaways and sandwich shops in and around St Mary's Bay, up to about a mile and a half out. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. Food hygiene inspections in St Mary's Bay are the job of Folkestone and Hythe council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Term dates shape school work: for a school like The Marsh Academy, an extract clean fits neatly into a half-term or summer break.

Why it’s worth doing now in St Mary's Bay
Once filters are saturated, more grease gets past them. The ductwork then loads up faster and grease readings can rise between cleans. A visit arranged in advance is far less disruptive than a callout on a busy day.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.

For landlords and multi-site operators
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 each one has its own record.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
When to call us in St Mary's Bay
Washing filters by hand doesn’t always get them clean. Grease hides in the folds of a baffle or the layers of a mesh, and a quick rinse leaves it there.
If you notice any of these, it’s worth a diagnosis:
- Grease dripping from the canopy
- Weak extraction at the canopy
- Bent or damaged filters that do not sit properly
- Missing filters in the filter bank
A hall kitchen that only cooks for events, whether near All Saints or elsewhere in St Mary's Bay, still needs its extract cleaned, just less often.
