Ductwork cleaning in Jersey Farm
Nobody sees duct grease building, so nobody notices it until something goes wrong. Flames pulled in from the cooking line can ignite it, and fire can then run along the ductwork to other parts of the building. Removing it is the whole point. The work covers bends and junctions, horizontal duct runs and multi-storey ducts, and common reasons people get in touch are proof of duct cleaning for the insurer and hardened, baked-on grease in long horizontal runs.
In a smaller place like Jersey Farm, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a few hours for a short run, longer for long runs and tall risers. For a place like Jersey Farm, we load the van from the survey notes so the work can be done in one visit where possible.
- We map the duct route and check where the access panels are.
- We measure grease thickness at set points before cleaning.
- Through the access panels, thick grease is removed by hand first.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Post-clean readings and photos go into the report, with any unreachable section listed.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Mention any locked doors, roof access or ceiling voids
- Mention any sign-in, permit or induction we need
Getting a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.
Advice
What affects the cost of ductwork cleaning
There’s no set price list, because sites vary so much. The quote depends on:
- Site rules, permits and inductions
- Parking and loading at the site
- The scale of the work
- How many systems or sites are involved
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Any previous report or certificate
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
If you need ductwork cleaning in Jersey Farm, give us a ring on 0345 646 2711, or send details by email. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. A fixed quote typically follows within one working day.
Do you need ductwork cleaning in Jersey Farm?
Risers carry the extract up through the building. Grease collects on the riser walls and gathers at the bottom, where it can pool. Panels along the riser make proper cleaning possible.
These are the problems we see most often:
- An insurer asking for TR19 evidence
- Grease pooling at the foot of the riser
- Fat dripping from the ductwork
- High readings at a recent grease test
If you run catering at a healthcare site, such as a hospital like Hill End Hospital about 1.5 miles south, the extract may need cleaning more often than a part-time kitchen.

Ductwork cleaning around Jersey Farm
Look up Jersey Farm on the FSA’s food hygiene register and you will find about 15 cafés, restaurants and staff canteens and about 12 takeaways and sandwich shops in and around Jersey Farm, up to about a mile and a half out. Behind every canopy among them is a run of ductwork that collects grease out of sight. Jersey Farm is covered by Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Environmental health officers from St Albans City council inspect food businesses in Jersey Farm. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Term dates shape school work: for a school like Skyswood Primary & Nursery School, an extract clean fits neatly into a half-term or summer break. Church and community hall kitchens, near Saint Mary's or anywhere around Jersey Farm, are easy to forget, but their extracts collect grease like any other.

Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Never cook with a filter missing
- Flag drips from the duct straight away
- Ask us about extra access panels where sections cannot be reached
- Keep the fan on while anything is cooking
Every panel we open is refitted when we finish, and the surrounding area is left clean. Waste grease and water are taken away.
The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.
Managing agents and facilities teams in Jersey Farm
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Jersey Farm questions
Who would carry out a food hygiene inspection at a kitchen in Jersey Farm?
That is St Albans City council, whose environmental health officers carry out food hygiene inspections in Jersey Farm. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Who is the fire and rescue service for Jersey Farm?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Jersey Farm. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How do you clean inside the ductwork?
We open each access panel and clean the section it reaches. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.
Will the duct clean disrupt the kitchen?
Out of hours, at a time that suits the kitchen. Larger systems may be cleaned over several nights, with the kitchen ready to cook each morning.
What do you do with what you remove?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
How do you protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Can extra access doors be added to the duct?
Yes, we install duct access panels. We place them where they help most, and we will recommend where.
What happens if it’s left?
TR19® is not law, but the duty to manage fire risk is. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, including the grease inside the extract ductwork. When a site near Jersey Farm shuts unexpectedly, the people who rely on it notice at once.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before work begins.

When it’s something else
A few issues sit outside what this work can do:
- A damper stuck open in the duct
- An extract fan that has stopped working
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
