Ductwork cleaning in Aston, done properly
Once air leaves the canopy, it travels through ductwork that most people never see. Every horizontal run and vertical riser collects grease along the way and a fire in the duct can spread through the building. We clean it from the inside, through access panels, to BESA TR19® Grease. Typical jobs include duct runs with no cleaning record and an insurer asking for TR19 evidence, on attenuators, horizontal duct runs and access panels.
For a kitchen in or near Aston, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
A written report with photos follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Seeing the system in photos first means the trip to Aston can be planned properly.
- 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 pictures go into the report, with any unreachable section listed.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Agree a time when the area can be out of use
- Arrange a key holder or contact on site

Advice
What ductwork cleaning looks like in Aston
The Food Standards Agency lists about 12 pubs, bars and clubs as registered food businesses within about 1.5 miles of central Aston. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. It’s East Hertfordshire council that sends environmental health officers to food businesses in Aston. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Fire safety in Aston falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Church and community hall kitchens, near Parish Church of St Mary the Virgin or anywhere around Aston, are easy to forget, but their extracts collect grease like any other. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Aston Bury is about 0.7 miles south), access may need planning.

Signs you need ductwork cleaning in Aston
Grease filters that do not seal let fat straight through. The duct then takes grease that the filters should have stopped and it fills faster.
Keep an eye out for these warning signs:
- Gaps where access panels were never fitted
- A duct nobody has opened in years
- Thick crusts of old grease along the duct
- Proof of duct cleaning for the insurer
Bursars and site managers at schools such as Aston St Mary's Church of England Aided Primary School tend to book extract cleaning for when the kitchen is empty.

Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Different parts, different methods
Bends and transitions
Wherever the duct turns or changes size, grease builds up. The air slows and drops its load, so we clean these points carefully.
Attenuators and discharge
Some systems have attenuators to reduce noise, but they can hold grease in their linings. We clean what can be reached and note anything that cannot.

When something else is needed
Not every problem is solved by ductwork cleaning, and we’d rather say so up front. It does not solve:
- Duct sections that need replacing
- A duct that is too small or badly routed for the kitchen (a design issue)
- Duct sealed behind fixed ceilings or walls
If you are not sure, just ring 0345 646 2711, or email photos and we’ll give you a straight answer before you book.

Aston: your questions answered
Can school kitchens in Aston be cleaned in the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 17 schools, colleges and universities with registered kitchens within about a mile and a half of Aston. Send us your term dates when you phone us on 0345 646 2711 or email us, and we’ll fit the work in.
Which fire authority looks after Aston?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Aston. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
What information do you need?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we’ll ask.
Will I get a report after the ducts are cleaned?
A photo report, with readings and before and after photos, plus a TR19 certificate for a full system clean. The report says when the next clean is due.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What happens if you can’t reach some of it?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
How do you clean inside the ductwork?
Through access panels along the duct. Thick deposits are removed by hand before degreasing, such as degreasers, hot water or steam.
How we price ductwork cleaning
Sites vary more than people expect. The main factors:
- Any permits to work or inductions
- The condition we find in the survey
- A single visit or a regular plan
- The number of sites or systems
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, phone us on 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. With your enquiry, please include:
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
