Ductwork cleaning in Woodhall Farm, done properly
In doctor’s terms, the ductwork is the system’s arteries: diagnose where grease has built up, clear it and confirm the result. Readings taken before and after show the difference, alongside before and after pictures. If you’re dealing with proof of duct cleaning for the insurer and smells of old cooking grease from the ductwork, we can help.
For a smaller kitchen near Woodhall Farm, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Run the extract fan throughout service
- Consider fitting panels where the report shows gaps
- Never cook with a filter missing
- Ask for a grease thickness test if the kitchen gets busier
Every panel we open is refitted when we finish, and the surrounding area is left clean. Waste grease and water are taken away.
Have access panels fitted where sections cannot be reached. Grease you can reach is grease that gets removed.
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

What else we do in Woodhall Farm
How we price ductwork cleaning
The diagnosis comes before the price. We look at:
- A single visit or a regular plan
- The times the site is available
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Helping us quote
When you call or email, it’s useful to have:
- Close-ups of filters, grilles, hatches or access panels
- Photos showing the whole system and its surroundings
- Problems your staff have spotted
- Your last certificate, test record or report
Getting a quote does not take long. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
For landlords and multi-site operators
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
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 are happy to quote for all of it.
What ductwork cleaning cannot fix
An honest diagnosis matters more to us than a booking, so here’s what ductwork cleaning will not do:
- Undersized or badly laid-out ducts
- Faulty fire dampers
- Duct sealed behind fixed ceilings or walls
Not sure which it is? You can phone us on 0345 646 2711 or email us and we’ll tell you honestly.
What we work on in Woodhall Farm
- Attenuators
- Horizontal duct runs
- Bends and junctions
- Access panels
- Multi-storey ducts
- Vertical risers
What the work involves, part by part
Horizontal duct runs
Grease settles on the floor of a flat duct run. Thick deposits are scraped out by hand before degreasing, then the walls and roof are cleaned too.
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
Grease, kitchens and Woodhall Farm
The FSA’s data shows about 42 pubs, bars and clubs and about 4 hotels, B&Bs and guest houses registered within 1.5 miles or so of the middle of Woodhall Farm. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Woodhall Farm sits within the area of Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from Dacorum council inspect food businesses in Woodhall Farm. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Healthcare kitchens, like those at hospitals such as Hemel Hempstead Hospital (about within half a mile south-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Bursars and site managers at schools such as South Hill Primary School tend to book extract cleaning for when the kitchen is empty. Church and community hall kitchens, near Alexandra Road Congregational Church or anywhere around Woodhall Farm, are easy to forget, but their extracts collect grease like any other.

Advice
Woodhall Farm questions
Who is the fire and rescue service for Woodhall Farm?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Woodhall Farm. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Do you clean school canteen extracts around Woodhall Farm out of term?
Yes, holiday work suits schools best. Food Standards Agency records list about 35 schools, colleges and universities with registered kitchens within about a mile and a half of Woodhall Farm. Just phone us on 0345 646 2711 or drop us a line with your term dates and we will plan around them.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. We usually quote within one working day, and emergencies are covered by our 24/7 line.
How often does extract ductwork need cleaning?
The duct is cleaned as part of the whole system, at intervals set by BESA guidance, ranging from 3-monthly to 12-monthly. Grease thickness testing shows whether that is often enough.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Can you quote from photos?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then call 0345 646 2711, or email photos.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Every site has its own report.
