How the job changes from site to site
Access panels
Access panels are the doors that let us into the duct. Where there are none, those sections cannot be cleaned, and TR19 expects them to be recorded.
Bends and transitions
Grease tends to pile up at elbows. It’s scraped out and degreased, and test it before and after.
How we handle ductwork cleaning in Aldbury
Nobody sees duct grease building, so nobody notices it until something goes wrong. A flare-up drawn up from the range can light it, carrying a fire along the duct and into rooms far from the kitchen. Removing it is the whole point. Common call-outs are for duct runs with no cleaning record and grease leaking from duct joints, on attenuators, access panels and multi-storey ducts.
Somewhere as small as Aldbury, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

How we price ductwork cleaning
Sites vary more than people expect. What affects the quote:
- Whether several sites go on one quote
- The times the site is available
- What state the system is in
- The scale of the work
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
What we need to know
You do not need the technical terms. It helps if you can send:
- Wide photos of the system and the area around it
- How we’d reach plant on a roof or in a plant room
- Detail shots of panels, filters and grilles
- Problems your staff have spotted
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
What ductwork cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what ductwork cleaning will not do:
- A failed fan motor at the end of the duct (a fan repair job)
- Fire dampers that don’t close (they need testing and remedials)
- Ductwork that was poorly designed
Not sure which it is? You can ring 0345 646 2711, or send details by email and we’ll tell you honestly.
Parts of the system we cover
- Access panels
- Multi-storey ducts
- Bends and junctions
- Attenuators
- Horizontal duct runs
- Vertical risers
What we do, step by step
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, and that takes from a few hours to more than one visit, depending on duct length and access. Seeing the system in photos first means the trip to Aldbury can be planned properly.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, photos and a next clean date.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us about site rules, permits or sign-in
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.

What ductwork cleaning looks like in Aldbury
Food Standards Agency data counts about 3 cafés, restaurants and staff canteens within roughly a mile and a half of the centre of Aldbury. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. Kitchens in Aldbury get their food hygiene inspections from Dacorum 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. Aldbury sits within the area of Hertfordshire 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.
Term dates shape school work: for a school like Aldbury Church of England Primary School, an extract clean fits neatly into a half-term or summer break. If you run catering at a historic house or estate in the area (Cholesbury Manor House is about 3.9 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning. Commuter trade near Tring station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

What happens if it’s left?
Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean straight away. Putting off the clean only pushes readings higher. A planned visit to Aldbury is easier to arrange than an emergency callout.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.

Aftercare tips
To keep the system working properly between visits:
- File each certificate and photo report in the maintenance log
- Ask us about extra access panels where sections can’t be reached
- Check readings when the menu changes
- Make sure filters are seated properly
Access panels are closed and sealed back up after cleaning, and the area around them is cleaned down. Grease and dirty water are contained and removed.
Run the extract the whole time the kitchen is cooking. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
Aldbury questions
Will you come out to Aldbury?
Yes. Aldbury is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you work in Aldbury outside opening hours?
Yes. We work evenings, overnight and at weekends. That way a site in Aldbury does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do we need to close while you work?
Normally not. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits so parts stay in use.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What happens if there are not enough access panels?
Ductwork needs access to be cleaned. Those parts are listed, and we can install panels so they’re reached next time.
Can you come out in an emergency?
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.
How is kitchen extract ductwork cleaned?
We get into the duct through its access panels. Heavy grease is scraped out by hand, then the surfaces are degreased with a method that suits the deposit, such as degreasers, hot water or steam.
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. Where responsibility is shared, records matter even more.
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’re happy to quote for all of it.
