Bilsham ductwork cleaning
Professional ductwork cleaning in and around Bilsham, timed so the site keeps working and finished with a written report and pictures.

- Grease pooling at the foot of the riser
- Hardened, baked-on grease in long horizontal runs
How we handle ductwork cleaning in Bilsham
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with each certificate issued through the BESCA portal. Typical jobs include smells of old cooking grease from the ductwork and a grease test showing the duct is overdue, across horizontal duct runs, vertical risers and bends and junctions.
Somewhere as small as Bilsham, 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.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too across West Sussex. Larger estates can be phased building by building around the people who use them.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
What ductwork cleaning cannot fix
We’ll always give you a straight diagnosis, so here’s what ductwork cleaning will not do:
- A damper stuck open in the duct
- Leaking duct joints that need repair
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly before you book.
What we work on in Bilsham
- Access panels
- Bends and junctions
- Attenuators
- Vertical risers
- Horizontal duct runs
- Multi-storey ducts
Keeping the system healthy
So the system stays in good health:
- Get panels fitted where the duct couldn’t be cleaned
- Diarise the next duct clean
- Run the extract fan throughout service
- Keep grease filters clean and fitted whenever you cook
Keep the certificate and report with the fire risk assessment. It’s the evidence an insurer or inspector may ask for, and the pictures make the duct’s condition easy to see.
Run the extract the whole time the kitchen is cooking. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
How the job changes from site to site
Multi-storey and shared buildings
In a shared building, the duct links the kitchen to other spaces, so the responsible person has more reason to keep it clean. The paperwork suits landlords and managing agents.
Bends and transitions
The join where the canopy meets the duct is a common hotspot. We clean it from the canopy side or through a nearby panel.
When to call us in Bilsham
A greasy duct is a fire path, in Bilsham as anywhere. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
Signs it’s time to call us include:
- A duct clean needed for an insurer
- A grease test showing the duct is overdue
- Stale grease odours from the duct
- Ductwork that has never been cleaned
A hospital like Bognor Regis War Memorial Hospital, about 2.8 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Bilsham questions
Who inspects food businesses in Bilsham?
Kitchens in Bilsham are inspected by Arun council’s environmental health officers. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Does the sea air around Bilsham make a difference to ductwork cleaning?
Yes, to a degree: at about 2 miles from the coast, Bilsham gets salt-laden air that corrodes metal faster. Rooftop fans, discharge cowls and fixings are checked for corrosion as well as grease.
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.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Do I get a certificate for ductwork cleaning?
When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. It includes readings, pictures and any unreachable sections.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
What shows that the ducts need a clean?
A grease thickness test gives the answer. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
Can you quote from pictures?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we normally come back within one working day. If pictures are not enough, we’ll survey first.
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
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 do not reach the grease that builds up further in. That part needs specialist access and equipment.
How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes from a few hours to more than one visit, depending on duct length and access, and we clear up before we go. Pictures of the system and its access let us plan the work in Bilsham before we set off.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- 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.
Before we arrive
- Have your last certificate or report to hand
- Tell us the best time to work, such as after service or at a weekend
- Clear the space around the work
Getting a quote
Some systems can be priced from photos; 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.

Grease, kitchens and Bilsham
Bilsham lies within about 2 miles of the sea. Metal on the roof weathers faster close to the coast, and the extract fan and cowl are no exception. The FSA’s food hygiene register includes about 5 pubs, bars and clubs in and around Bilsham, up to about a mile and a half out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Kitchens in Bilsham get their food hygiene inspections from Arun council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Term dates shape school work: for a school like Yapton CE Primary School, an extract clean fits neatly into a half-term or summer break. If you run a church or community hall kitchen, near Bilsham Chapel or elsewhere in Bilsham, its extract still collects grease from every lunch and event.
