How we handle grease filter exchange in Northdown
Each visit is quick and tidy. The greasy filters come out, clean ones go in, and we check they’re seated with no gaps. Anything that needs attention is pointed out. The work covers mesh filters, restaurants and pubs and school and hospital kitchens, and common reasons people get in touch are grease left in baffles after washing and a canopy running with filters missing.
In a smaller place like Northdown, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
Duct Doctor has been trading since 2009, and we are 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.

What happens on the day
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the grease filter exchange, clear away and leave you the report. The visit itself takes anything from a few minutes to an hour or so, depending on the number of filters. Because the survey comes first, a visit to Northdown can normally be finished without a second trip.
- We look at the canopies and the condition of the filters.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.

What affects the quote in Northdown
The survey tells us what the work involves. We look at:
- Working hours and out-of-hours timing
- The size of the system
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
What to send for a quote
When you call or email, it’s useful to have:
- The site address and the type of premises
- When the site is open and when it’s quiet
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
For a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
Why act early in Northdown
Grease dripping from the canopy is a sign the filters can’t hold any more. Left, it ends up on equipment, food areas and staff and that is the kind of thing inspectors look for. Light use slows the build-up but does not stop it.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711, or email photos, and we’ll explain what it covers.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Northdown: your questions answered

Yes. The holidays are the usual time for school work. Food Standards Agency records list about 10 schools, colleges and universities with registered kitchens within about a mile and a half of Northdown. Tell us your holiday dates and we will book the visit for when the site is empty.

Every certificate and report from each visit, filed in the maintenance log, along with your own cleaning log. BESA says certificates should show the date, location and technician.

Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We do not leave it behind.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.

Kitchen extracts in Northdown
Sea air reaches Northdown, 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. The Food Standards Agency lists about 19 pubs, bars and clubs and about 5 hotels and B&Bs as registered food businesses in and around Northdown, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Northdown, food businesses are inspected by environmental health officers from Thanet council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.
If your kitchen is in a listed or historic building, like the houses around Northdown (Quex Park is about 4.5 miles west), fitting access panels needs care. A hospital like Queen Elizabeth the Queen Mother Hospital, about 1.4 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. For schools such as Palm Bay Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Between visits
Results last longer with the right care. We suggest:
- Do not refit a filter that’s bent
- Keep the canopy clear for exchange visits
- Make sure no filter is left out
- Never cook with the extract switched off
The canopy looks cleaner and the air moves better from the moment they’re fitted. Always run the extract during cooking so they catch grease as intended.
Damaged filters leave gaps in the defence. Replacing them early protects the plenum and ductwork.
What the work involves, part by part
School, care home and staff kitchens
Even kitchens with fixed meal times build up grease, though often more slowly.
Baffle filters
Baffle filters use overlapping metal blades that force the air to change direction. Grease drops out as it does.
