Ductwork Cleaning in Sepham Heath
Our technicians work in Sepham Heath on ductwork cleaning. Fixed quotes, work around your opening hours and photo reports as standard.
- Stale grease odours from the duct
- Duct runs that can’t be reached
- Years of grease along the duct floor
What happens on the day
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes from a few hours to more than one visit, depending on duct length and access. If you can send pictures, we can arrive in Sepham Heath knowing what to expect.
- First we diagnose: the route, the access and the grease levels.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access panel.
- We take extra care at bends and at the foot of risers.
- The duct is signed off with readings, pictures and a next clean date.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Ductwork cleaning for kitchens and businesses in Sepham Heath
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Grease settles along every metre of it, and that’s where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. If you’re dealing with grease seeping out of the duct seams and stale grease odours from the duct, we can put it right, from access panels, bends and junctions and multi-storey ducts onwards.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Sepham Heath questions
Can you clean school kitchen extracts in Sepham Heath during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Sepham Heath. Just phone us on 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Which council inspects kitchens in Sepham Heath?
The local authority for Sepham Heath is Sevenoaks council, and its environmental health team does the inspecting. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
What do you need from me for a quote?
Some photos and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
Can you clean ductwork with no access panels?
Without a way in, a section cannot be cleaned properly. We record those sections on the report and can fit access panels.
How can I tell if my extract ducts are dirty?
A grease thickness test gives the answer. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Have the grease measured if cooking hours go up
- Consider fitting panels where the report shows gaps
- Leave a way through to the access panels
- Report any grease dripping from duct joints
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
Keep the fan on throughout service. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
What we’re called out for in Sepham Heath
A vertical riser can run up several floors. Grease collects on the riser walls and gathers at the bottom, where it can pool. Access along its height is needed to clean it properly.
Any of these means the system needs a check-up:
- Sections of duct with no access panels
- Grease seeping out of the duct seams
- A duct nobody has opened in years
- Smells of old cooking grease from the ductwork
If you run catering at a historic house or estate in the area (Lullingstone Castle is about 3.1 miles north-east), event kitchens in older buildings often have awkward duct runs that need planning.
What your quote should include
- How they set the interval to the next visit
- Whether the quote is based on a survey or photos
- Whether the figure could change on the day
- What records you’ll receive afterwards
Why deal with it now?
Insurers know the risk of a greasy duct. Many policies require TR19 cleaning, and a claim may be refused or reduced without evidence. A certificate that covers the ductwork is what they want to see. Planning a trip to Sepham Heath ahead is easier for everyone than a rushed one.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

Ductwork cleaning around Sepham Heath
The FSA’s food hygiene register shows about 3 restaurants, cafés and works canteens across Sepham Heath and its immediate surroundings (about a mile and a half).

In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Environmental health officers from Sevenoaks council inspect food businesses in Sepham Heath. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

What a clean will not put right
In fairness, there are a few things this work won’t fix:
- Undersized or badly laid-out ducts
- A damper stuck open in the duct
- Leaking duct joints that need repair
If in doubt, give us a ring on 0345 646 2711, or email photos and we’ll say what we think before you book.
Parts of the system we cover
- Access panels
- Bends and junctions
- Multi-storey ducts
- Vertical risers
- Horizontal duct runs
- Attenuators
Different parts, different methods
Vertical risers
A riser takes the duct up through one or more floors. Grease runs down the walls and gathers at the base, which is one of the points we test.
Attenuators and discharge
Attenuators, where fitted, quieten the extract, and their linings can soak up grease. They’re cleaned where possible and recorded if not.
Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
