About our ductwork cleaning in Walstead
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, with each certificate issued through the BESCA portal. If you have an insurer asking for TR19 evidence and duct runs that can’t be reached, we can put it right, from horizontal duct runs, attenuators and bends and junctions onwards.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Common questions in Walstead
Which fire and rescue service is responsible for Walstead?
Walstead is in the area of West Sussex Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you work at weekends in Walstead?
Yes. We work evenings, overnight and at weekends. That way a site in Walstead doesn’t have to lose a day’s trading. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What about areas you can’t get to?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
How much does ductwork cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before we start.
What else we do in Walstead
Walstead kitchens: local notes
Food Standards Agency records list about 11 restaurants, cafés and canteens within 1.5 miles or so of the middle of Walstead. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. Kitchens in Walstead get their food hygiene inspections from Mid Sussex council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Walstead falls to West Sussex Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Volunteers running a hall kitchen near Church of the Good Shepherd, or anywhere in Walstead, may not know when the extract was last cleaned, and a grease test settles it. If you run catering at a healthcare site, such as a hospital like Princess Royal Hospital about 1.2 miles south-west, the extract may need cleaning more often than a part-time kitchen.

Do you need ductwork cleaning in Walstead?
A duct with too few access doors cannot be fully cleaned. Sections between panels go uncleaned, sometimes since the system was installed, and grease there keeps thickening unseen.
What we’re most often called out for:
- A grease test showing the duct is overdue
- A duct nobody has opened in years
- Gaps where access panels were never fitted
- Grease pooling at the foot of the riser
School kitchens, at schools like Northlands Wood Primary Academy for example, are usually cleaned in the holidays so no lunches are lost.
Questions to ask before booking
- What records you’ll receive afterwards
- Proof of insurance
- When they can work, and whether that’s outside your opening hours
- Whether the quote shows VAT
When it’s something else
A few issues sit outside what this work can do:
- A failed fan motor at the end of the duct (a fan repair job)
- Ductwork that was poorly designed
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we’ll tell you honestly before booking.
What the work covers
- Access panels
- Attenuators
- Vertical risers
- Horizontal duct runs
- Bends and junctions
- Multi-storey ducts
Between visits
So the system stays in good health:
- Don’t block access panels with shelving or stock
- Store the certificate with the fire risk assessment
- Check readings when the menu changes
- Keep grease filters clean and fitted whenever you cook
After the clean, the same points are tested again, so the report shows the before and after figures. Before and after photos sit next to the numbers.
Some signs mean the duct needs attention sooner: grease leaking from duct joints, smells, or a fan that sounds rough. Testing will show whether any section has reached 500 microns.
How it works
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes a shift or more, depending on the length of the runs and the number of access points, and we clear up before we go. A few pictures of the system help us make the most of a visit to a place like Walstead.
- 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.
- Heavy deposits come out by hand, then each section is degreased.
- We close up, re-test, photograph and record anything out of reach.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Have your last certificate or report to hand
- Agree a time when the area can be out of use
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Then phone us on 0345 646 2711 or use the quote form.
Related advice
What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What the work involves, part by part
Vertical risers
In taller buildings, a riser may pass through several floors and fire compartments, so fire dampers may be fitted where it crosses them. Damper testing is a separate service.
Horizontal duct runs
The underside of a horizontal duct collects the most grease. We scrape out the heavy layer first, then the walls and roof are cleaned too.
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
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.
