Ductwork cleaning for kitchens and businesses in Essendon
We treat ductwork like a doctor treats arteries: diagnose where grease has built up, clear it and confirm the result. Grease readings before and after give you the evidence, alongside before and after pictures. Common call-outs are for a rancid smell from the extract duct and readings above 200 microns from a grease thickness test, across access panels, multi-storey ducts and bends and junctions.
In a small place like Essendon, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Aftercare tips
A little care between visits keeps the system in better shape. Our advice:
- Consider fitting panels where the report shows gaps
- Have the grease measured if cooking hours go up
- Report any grease dripping from duct joints
- Keep the fan on while anything is cooking
File the paperwork in the maintenance log. It’s the evidence an insurer or inspector may ask for, and the pictures make the duct’s condition easy to see.
Watch for warning signs between cleans: drips from the ductwork, stale smells or a noisy fan. A grease thickness test can confirm whether a spot clean is needed.
Your questions about ductwork cleaning in Essendon
Who inspects food businesses in Essendon?
Kitchens in Essendon are inspected by Welwyn Hatfield council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you work in villages like Essendon?
Yes, Essendon is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
What’s involved in cleaning extract ducts?
Through access panels along the duct. Thick deposits are removed by hand before degreasing, such as degreasers, hot water or steam.
Can you price the work without visiting?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. If photos aren’t enough, we’ll survey first.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Signs you need ductwork cleaning in Essendon
Grease filters that do not seal let fat straight through. More grease reaches the ductwork than it should, and build-up speeds up.
Look out for these warning signs:
- Heavy grease at the base of a riser
- A grease test showing the duct is overdue
- A duct nobody has opened in years
- Fat dripping from the ductwork
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Queen Elizabeth II Hospital is the nearest hospital to Essendon, about 2 miles north-west.
Questions to ask before booking
- How areas they cannot reach will be recorded
- When they can work, and whether that’s outside your opening hours
- Exactly which parts of the system are covered
- Which accreditations they hold, and whether you can check them
Kitchen extracts in Essendon
According to Food Standards Agency records, there are about 4 pubs, bars and clubs within roughly a mile and a half of the centre of Essendon. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Essendon 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. Food hygiene inspections in Essendon are the job of Welwyn Hatfield council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand.
If you look after a school kitchen, at a school such as Essendon CofE (VC) Primary School or anywhere near Essendon, the holidays are the usual time for a TR19® clean. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Hatfield House is about 2.4 miles west), access may need planning.

Landmarks near Essendon
Locally, jobs take us to businesses close to The Salisbury Crest Public House. Essendon’s nearest station is Bayford station, about 2.5 miles east. Nearby you will also find Queen Elizabeth II Hospital (2 miles north-west) and The Bunker at Hatfield Police Station (3.6 miles west). The countryside around Essendon includes Willowmead.
Leave it or put it right?
Fire inside a duct is out of sight and out of reach. It can travel through the ductwork to other parts of the building, so cleaning the duct is as important as cleaning the hood. Planning a trip to Essendon ahead is easier for everyone than a rushed one.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

More services for Essendon
Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes a shift or more, depending on the length of the runs and the number of access points. In a small place like Essendon, the journey is planned ahead and the visit arranged around the site’s hours.
- Diagnosis: a survey of the duct’s route, size and access.
- You get a fixed price before work starts.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, photos and a recommended next clean date complete the job.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Let us know about permits to work or site inductions
- Mention any parking or loading restrictions
Getting a quote
To get a fixed quote, ring 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We normally come back within one working day.
Advice
In-house cleaning or a specialist?
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
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.
Honest limits
A few issues sit outside what this work can do:
- A worn-out fan that needs replacing
- Duct sealed behind fixed ceilings or walls
- Duct sections that need replacing
If you are not sure, just ring 0345 646 2711, or email photos and we will give you a straight answer before you book.
