Ductwork cleaning in Patching
Ductwork in Patching is cleaned the same thorough way as everywhere else we work: we test the grease first, remove thick deposits by hand and degrease what’s left. Post-clean readings and pictures complete the record. The work covers vertical risers, bends and junctions and horizontal duct runs, and the jobs we see most are grease pooling at the foot of the riser and duct runs with no cleaning record.
In a small place like Patching, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
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.

How it works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes from a few hours to more than one visit, depending on duct length and access. Visits to a village like Patching are booked in advance, at a time that suits whoever runs the site.
- We start by working out how the duct runs and where it can be opened.
- Set points along the runs are tested for grease.
- Access panels are opened and heavy deposits scraped out by hand.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
How to prepare
- Dig out any earlier paperwork for the system
- Agree a time when the area can be out of use
- Clear loose items from the work area

What a clean won’t put right
We’ll always give you a straight diagnosis, so here’s what ductwork cleaning will not do:
- Duct sealed behind fixed ceilings or walls
- A damper stuck open in the duct
- Duct sections that need replacing
If in doubt, ring 0345 646 2711 or drop us a line and we will say what we think.
Where we work
- Multi-storey ducts
- Access panels
- Horizontal duct runs
- Vertical risers
- Bends and junctions
- Attenuators
What happens if it’s left?
Fire inside a duct is out of sight and out of reach. The duct can carry it to rooms, floors or roof spaces well away from the kitchen, which is why the duct matters as much as the canopy. Our emergency line runs 24/7, but a planned visit to Patching is calmer for everyone.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
What ductwork cleaning looks like in Patching
According to Food Standards Agency records, there are about 3 bars, pubs and nightclubs in Patching and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Food hygiene inspections in Patching are the job of Arun council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Patching falls to West Sussex 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.
If you run catering at a historic house or estate in the area (Ecclesden Manor is about 1.5 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning. If you run catering at a healthcare site, such as a hospital like Zachary Merton Hospital about 3.4 miles south-west, the extract may need cleaning more often than a part-time kitchen. Term dates shape school work: for a school like Clapham and Patching CofE Primary School, an extract clean fits neatly into a half-term or summer break.

Between visits
Good habits slow the build-up between visits. Our tips:
- Get panels fitted where the duct couldn’t be cleaned
- Leave a way through to the access panels
- Keep to the interval on the report
- Make sure filters are seated properly
Grease readings are taken again at the same set points, giving you before and after readings. Photos of each section go alongside them.
Some signs mean the duct needs attention sooner: drips from the ductwork, stale smells or a noisy fan. Testing will show whether any section has reached 500 microns.
How we price ductwork cleaning
The quote reflects the site in front of us. We take into account:
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Photos showing the whole system and its surroundings
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
We do not publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, phone us on 0345 646 2711 or use the quote form.
Common questions in Patching
Who would carry out a food hygiene inspection at a kitchen in Patching?
Food hygiene inspections in Patching are carried out by Arun council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can school kitchens in Patching be cleaned in the holidays?
Yes, out-of-term visits are normal for schools. There are about 4 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Patching. Send us your term dates when you call us on 0345 646 2711 or send us an email, and we will fit the work in.
Can you quote from photos?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Do you install duct access panels?
Yes, we install duct access panels. Panels go where they give the best access to sections that couldn’t be reached, and we’ll recommend where.
Where does the waste go?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
How do you clean inside the ductwork?
Each section is cleaned through its own panel. Grease is scraped out first, then degreased, with readings taken before and after.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we’re fully insured.

What the work involves, part by part
Vertical risers
A riser takes the duct up through one or more floors. Grease runs down the walls and gathers at the base, which is one of the points we test.
Multi-storey and shared buildings
Long ducts in larger buildings can mean several visits. Visits are planned around the building’s hours, out of hours where possible.
