What affects the quote in Thong
A fixed price needs a few facts first. We check:
- Whether it’s a one-off visit or part of a schedule
- Access, including roofs, risers and ceiling voids
- Any permits to work or inductions
- The condition of the system
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before work begins.
What we need to know
When you call or email, these details help:
- Your last certificate, test record or report
- The site address and the type of premises
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
Extract fan cleaning in Thong, done properly
Is the extract fan louder than it used to be, or the airflow weaker? A few details or a photo help when you call 0345 646 2711 or use the quote form, and we will send you a fixed quote for extract fan cleaning in Thong, normally within one working day. Typical jobs include a fan shaking on its mounts and less air being pulled from the kitchen, on discharge points, axial fans and fan housings.
Somewhere as small as Thong, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
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 are fully insured.

When to call us in Thong
Poor filters mean a greasier fan. Missing, damaged or badly fitted filters let grease travel the whole system, so the fan takes far more than it should.
The symptoms we’re asked about most are:
- Vibration from an unbalanced impeller
- Grease stains around the discharge
- A fan motor running hot under a coat of grease
- Hot, greasy smells near the fan
Where a hall near Church of St Peter and St Paul, or anywhere in Thong, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Extract fan cleaning in Thong: the local picture
The coast is only about 3 miles from Thong. Near the sea, the fan and discharge at the top of a kitchen extract corrode faster than they would inland. According to Food Standards Agency records, there are about 9 pubs, bars and clubs in Thong and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. It’s Gravesham council that sends environmental health officers to food businesses in Thong. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Thong is Gravesham Community Hospital, about 2.8 miles north-west. If your kitchen is in a listed or historic building, like the houses around Thong (Cobham College is about 1.5 miles south), fitting access panels needs care.
Thong is about 2 miles south-east of Gravesend, in Kent. Thong gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with photos. Thong is one of 922 places in Kent we cover for extract fan cleaning. You can also see our page for Maidstone, about 11 miles away.
Work in DA12 is surveyed, quoted and booked the same way as anywhere else.

Thong questions
Can you clean school kitchen extracts in Thong during the holidays?
Yes, holiday work suits schools best. There are about 18 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Thong. Booking early in the term gives the best choice of holiday dates.
Is extract fan cleaning any different in a coastal place like Thong?
Yes, to a degree: at about 3 miles from the coast, Thong gets salt-laden air that corrodes metal faster. We look at fans, cowls and fixings for rust as well as grease.
Is Thong in your area?
Yes. Our area takes in London and the counties of South East England, Thong included.
Why is my extract fan noisy?
Often it’s grease on the impeller. Uneven build-up on the blades throws the fan off balance, causing vibration and noise. If cleaning does not, the bearings or motor may need attention.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Which kinds of sites do you work on?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Does the law say we must follow TR19?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.
Will we have to shut during the visit?
Not typically. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
What we do, step by step
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes an hour or two for most single fans. A quick note on how to find the site and where to park makes a visit to Thong run smoothly.
- The fan is found and its type, access and isolation checked.
- It’s isolated so it can’t run while we work.
- We scrape the heavy grease from the blades and housing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
Before we arrive
- Find the previous report, if there is one
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards

Related advice
Why it’s worth doing now in Thong
For a kitchen in Thong, a noisy, greasy fan is often the first sign the whole system is overdue. If the fan is coated, the duct before it typically is too so a full TR19 clean may be due. It’s worth booking a check, because nobody sees inside a duct day to day.
We do not 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.

What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Listen for new noises or vibration from the fan
- Make sure the fan is included each time
- Run the extract throughout cooking
- Note any drop in extraction at the canopy
When we’ve finished, the fan is reassembled and run. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.
Make sure the fan is reachable. Clear access means it’s never left out of a clean, whether it’s on a roof, in a ceiling or on a wall.
