How we handle canopy cleaning in Thong
The canopy is the part of the extract everyone in the kitchen sees. It’s also the first place cooking vapour meets, so grease gathers on its inner skin, seams and gutters. Our canopy clean covers the shell inside and out, plus the plenum and the filter housing. If you have a sticky, discoloured canopy and wet, greasy drips from the hood, we can help, from wall canopies, island canopies and grease gutters onwards.
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, whatever the size of the place.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

What else we do in Thong
What affects the cost of canopy cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Parking and loading at the site
- How many systems or sites are involved
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before we start.
Asking for a quote
There’s no need for technical detail. Just send:
- Any access panels or hatches you can see
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, ring 0345 646 2711 or send us an email.
Signs you need canopy cleaning in Thong
Any canopy in Thong that’s used for cooking will gather grease in the end. It’s fuel, sitting directly over the burners, so a flare-up near a greasy hood can quickly become a fire.
Look out for any of the following:
- Heavy deposits behind the grease filters
- Drips from the canopy onto the range
- A greasy hood noticed by an inspector
- A sticky, discoloured canopy
A hall kitchen that only cooks for events, whether near Church of St Peter and St Paul or elsewhere in Thong, still needs its extract cleaned, just less often.
What to look for in a quote
- Exactly which parts of the system are covered
- What insurance they carry
- What records you’ll receive afterwards
- Which accreditations they hold, and whether you can check them
What canopy cleaning cannot fix
In fairness, some problems need a different fix:
- A hood that doesn’t cover the cooking line
- Bent or broken filters
- Grease in the duct runs and risers behind the canopy
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we will tell you honestly before you book.

What we do, step by step
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. All told, the work takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. We agree a date with you, plan the drive to Thong and turn up when the site is quiet.
- We look at the canopy, filters and troughs first.
- Out of hours, the range is switched off, cooled and covered.
- With the filters removed, the plenum and filter channels are cleaned.
- Inside and out, the hood and its troughs are cleaned.
- We put the filters back, tidy up and photograph the finished canopy.
Preparing for the visit
- Have your last certificate or report to hand
- Let us know about permits to work or site inductions
- Move anything stored near the system

Why deal with it now?
A greasy canopy is fuel directly above the flame. A flare-up can catch it and be drawn into the plenum and duct, where a fire is much harder to stop. A clean canopy takes that fuel away. In a small place like Thong, a system that fails can take a site out of use.
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711, or email photos, and we will explain what it covers.

Grease, kitchens and Thong
Thong is within about 3 miles of the coast. Salt air speeds up corrosion of roof-level fans, discharge cowls and their fixings. The Food Standards Agency lists about 9 pubs and bars as registered food businesses in Thong and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Fire safety in Thong falls to Kent Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Historic houses near Thong, such as Cobham College about 1.5 miles south, are a reminder that older buildings with event kitchens can have long, awkward duct routes. Healthcare kitchens, like those at hospitals such as Gravesham Community Hospital (about 2.8 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands.
Thong is about 2 miles south-east of Gravesend, in Kent. Thong gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with pictures. Thong is one of 922 places in Kent we cover for commercial clients. You can also see our page for Maidstone, roughly 11 miles from Thong.

Questions from Thong
Do you work in villages like Thong?
Yes. Villages and rural sites across the South East are part of our work, Thong included. Photos of the system and directions to the site help us plan the visit.
Does coastal air change anything about canopy cleaning in Thong?
It can. Thong is within about 3 miles of the coast, and salt air speeds up corrosion. Corroded fixings and housings are noted on the report so they can be dealt with.
What about areas you can’t get to?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Does the law say we must follow TR19?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
Is the inside of the hood cleaned?
The full canopy, inside and out, and the plenum behind it. Grease troughs and filter channels are emptied and degreased as part of the job.
Who is responsible for fire safety on the premises?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Why is my canopy dripping grease?
Most drips come from overflowing troughs, damaged filters or a plenum thick with grease. We clean the canopy, plenum and troughs and tell you what we find.
What kinds of canopies do you clean?
Wall canopies, island canopies and single hoods over individual appliances. Each one is cleaned inside and out, with the plenum behind the filters.
Different parts, different methods
School and staff canteen kitchens
Canteen staff see the canopy, not the duct behind it. We clean it and the plenum behind the filters, so what’s out of sight is dealt with too.
Wall canopies
At the back of the canopy, behind the filters, grease builds up unseen. We remove the filters to reach it and degrease it properly.
