Ductwork cleaning in Thong, Kent
Our technicians work in Thong on cleaning of kitchen extract ductwork, horizontal runs and vertical risers through access panels. Fixed quotes, work around your opening hours and photo reports on every job.
- Heavy grease at the base of a riser
- An insurer asking for TR19 evidence
- Grease seeping out of the duct seams
Aftercare tips
So the system stays in good health:
- Do not block access panels with shelving or stock
- Keep the fan on while anything is cooking
- File each certificate and photo report in the maintenance log
- Report any grease dripping from duct joints
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
Some signs mean the duct needs attention sooner: drips from the ductwork, stale smells or a noisy fan. A grease thickness test can confirm whether a spot clean is needed.
About our ductwork cleaning in Thong
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it, and that’s where a kitchen fire can travel. We clean it from the inside, through access panels, to BESA TR19® Grease. If you have high readings at a recent grease test and hardened, baked-on grease in long horizontal runs, we can put it right, from vertical risers, attenuators and multi-storey ducts onwards.
In a village or hamlet like Thong, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes from a few hours to more than one visit, depending on duct length and access, and the area is cleaned down before we leave. A few pictures of the system help us make the most of a visit to a place like Thong.
- We map the duct route and check where the access panels are.
- Set points along the runs are tested for grease.
- We open the panels and scrape out the heaviest grease.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Post-clean readings and pictures go into the report, with any unreachable section listed.
How to prepare
- Tell us about site rules, permits or sign-in
- Let us know about parking and loading
- Let us know when the site is closed or quiet
How to get a quote
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Then phone us on 0345 646 2711 or drop us a line.
Advice
For landlords and multi-site operators
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
When something else is needed
Not every problem is solved by ductwork cleaning, and we’d rather say so up front. It does not solve:
- A damper stuck open in the duct
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- Ductwork that was poorly designed
Not sure which it is? You can call 0345 646 2711 or use the quote form and we will tell you honestly.

Thong questions
Can you get to a site in Thong?
Yes, Thong is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Does being near the coast affect ductwork cleaning in Thong?
It can. Thong is within about 3 miles of the coast, and salt air speeds up corrosion. A fan housing that’s rusting near the coast can fail sooner, so it’s worth catching early.
What if part of the duct can’t be reached?
Without a way in, a section can’t be cleaned properly. Those parts are listed, and we can install panels so they’re reached next time.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Where does the waste go?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.
How long does ductwork cleaning take?
Short runs are quick, while long ducts and tall risers can need more than one visit. Visits are planned out of hours.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
What information do you need?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
How we price ductwork cleaning
Before we fix a price, we need to know a few things. We check:
- Whether it’s a one-off visit or part of a schedule
- How many systems or sites are involved
- Working hours and out-of-hours timing
- The condition we find in the survey
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before any work starts.
What we need to know
Many jobs can be priced from pictures and some basics. Useful things to send:
- The times we could work without disrupting the site
- Close-ups of filters, grilles, hatches or access panels
- Photos showing the whole system and its surroundings
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
What we’re called out for in Thong
A duct with too few access doors can’t be fully cleaned. Stretches with no way in may never have been touched, and the grease there keeps building out of sight.
Common reasons sites call us are:
- Thick crusts of old grease along the duct
- Sections of duct with no access panels
- A rancid smell from the extract duct
- Ductwork that has never been cleaned
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Gravesham Community Hospital is the nearest hospital to Thong, about 2.8 miles north-west.
What to look for in a quote
- Proof of insurance
- When they can work, and whether that’s outside your opening hours
- Whether the price is fixed
- How VAT is shown on the quote
Part by part
Attenuators and discharge
At the end of the duct is the discharge. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.
Access panels
After cleaning, every panel is closed and sealed so the duct stays tight. A damaged panel is noted on the report.
Ductwork cleaning around Thong
The coast is only about 3 miles from Thong. Metal on the roof weathers faster close to the coast, and the extract fan and cowl are no exception. Food Standards Agency data counts about 12 cafés, restaurants and staff canteens and about 18 takeaways in Thong and the streets around it, up to about 1.5 miles out. The duct above a busy canopy coats itself in grease long before anyone sees it. Food hygiene inspections in Thong are the job of Gravesham council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
Church and community hall kitchens, near Church of St Peter and St Paul or anywhere around Thong, are easy to forget, but their extracts collect grease like any other. If you run catering at a historic house or estate in the area (Cobham College is about 1.5 miles south), event kitchens in older buildings often have awkward duct runs that need planning.
