Ductwork cleaning for kitchens and businesses in Dunsfold
In doctor’s terms, the ductwork is the system’s arteries: diagnose where grease has built up, clear it and confirm the result. Grease readings before and after give you the evidence, alongside before and after pictures. Typical jobs include thick crusts of old grease along the duct and thick deposits at the bottom of a vertical duct, across bends and junctions, attenuators and multi-storey ducts.
Work in a small place like Dunsfold starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

FAQs for Dunsfold
Do you work at weekends in Dunsfold?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Dunsfold needn’t be disturbed. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.
Do you work in villages like Dunsfold?
Yes. Villages and rural sites across the South East are part of our work, Dunsfold included. Just mention lanes, gates or anything else about the site when you book.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Will we have to shut during the visit?
Typically not. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages so parts stay in use.
How do you clean inside the ductwork?
We get into the duct through its access panels. Heavy grease is scraped out by hand, then the surfaces are degreased with a method that suits the deposit, such as degreasers, hot water or steam.
Is TR19 cleaning required by law?
Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005 in England and Wales.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Who has the legal duty for fire safety?
The law calls them the responsible person. That’s generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes from a few hours to more than one visit, depending on duct length and access. A quick note on how to find the site and where to park makes a visit to Dunsfold run smoothly.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
How to prepare
- Name a contact who can let us in at the agreed time
- Tell us about site rules, permits or sign-in
- Mention any locked doors, roof access or ceiling voids
How to get a quote
To help us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or send us an email.

Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Get panels fitted where the duct couldn’t be cleaned
- Keep grease filters clean and fitted whenever you cook
- Don’t switch the extract off early
- Store the certificate with the fire risk assessment
When the duct is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.
Leave it or put it right?
TR19® isn’t law, but the duty to manage fire risk is. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. Rural sites cannot always move to another kitchen or room when something fails.
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

How the job changes from site to site
Vertical risers
A riser takes the duct up through one or more floors. Grease collects on the walls and at the foot of the riser, which is one of the points we test.
Access panels
After cleaning, every panel is closed and sealed so the duct stays tight. A damaged panel is noted on the report.

Grease, kitchens and Dunsfold
Environmental health officers from Waverley council inspect food businesses in Dunsfold. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand. About 33 miles out from central London, Dunsfold is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you.
A hall kitchen that only cooks for events, whether near Church of St Mary and All Saints or elsewhere in Dunsfold, still needs its extract cleaned, just less often. If you run catering at a healthcare site, such as a hospital like Milford Hospital about 4.3 miles north-west, the extract may need cleaning more often than a part-time kitchen.

What affects the cost of ductwork cleaning
Every site gets its own quote. This is what makes a difference:
- One-off work versus a regular cycle
- Site rules, permits and inductions
- The scale of the work
- How many systems or sites are involved
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- 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
- Detail shots of panels, filters and grilles
- The paperwork from the last visit, if you have it
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before work begins.
Multi-site and managed buildings
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
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. The inside of ducts and units needs a specialist.
