About our ductwork cleaning in Ayres End
The ductwork is where an extract clean is won or lost. Sections with no way in can go uncleaned for years. We open up every reachable section and record any we cannot reach, so you know exactly where you stand. Typical jobs include high readings at a recent grease test and a rancid smell from the extract duct, across access panels, multi-storey ducts and horizontal duct runs.
In a village or hamlet like Ayres End, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Why it’s worth doing now in Ayres End
A fire in a greasy duct is hard to reach and hard to stop. It can travel through the ductwork to other parts of the building, which is why the duct matters as much as the canopy. Systems in rural buildings are often out of sight and out of mind.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

Other services in Ayres End
Between visits
A little care between visits keeps the system in better shape. Our advice:
- Get panels fitted where the duct couldn’t be cleaned
- Make sure filters are seated properly
- Tell us if grease leaks from the ductwork
- Book the next clean before the recommended date
Grease readings are taken again at the same set points, giving you before and after readings. Photos of each section go alongside them.
Keep to the cleaning interval on the report. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes a few hours for a short run, longer for long runs and tall risers, and the area is cleaned down before we leave. A quick note on how to find the site and where to park makes a visit to Ayres End run smoothly.
- The duct route is surveyed and every access point found.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Before we arrive
- Clear loose items from the work area
- Allow time for equipment near the work to be turned off and cool down
- Let us know about permits to work or site inductions

Quotes are quick. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

FAQs for Ayres End
Do you cover smaller places like Ayres End?
Yes, Ayres End is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can you come to Ayres End after we close?
Yes, evening, overnight and weekend work is normal for us. It means the site in Ayres End keeps running as normal. Just ring 0345 646 2711 or drop us a line with your opening times and we will plan around them.
Who is the responsible person?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
How much does ductwork cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we will usually reply within one working day.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Is TR19 cleaning required by law?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
How do you know if the ductwork needs cleaning?
A grease thickness test gives the answer. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
Do you need ductwork cleaning in Ayres End?
A vertical riser can run up several floors. Grease collects on the riser walls and gathers at the bottom as liquid grease runs down. Access along its height is needed to clean it properly.
It’s time to book a visit if you see:
- Grease pooling at the foot of the riser
- Hardened, baked-on grease in long horizontal runs
- A duct clean needed for an insurer
- Ductwork that has never been cleaned
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Ayres End is St Albans City Hospital, about 2.5 miles south.

Ductwork cleaning around Ayres End
Food Standards Agency records list about 15 restaurants, cafés and canteens and about 5 takeaways and sandwich shops across Ayres End and its immediate surroundings (about a mile and a half). Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. Environmental health officers from St Albans City council inspect food businesses in Ayres End. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Ayres End falls to 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.
If your kitchen is in a listed or historic building, like the houses around Ayres End (Childwickbury Manor is about 1.6 miles south-west), fitting access panels needs care. Term dates shape school work: for a school like The Grove Infant and Nursery School, an extract clean fits neatly into a half-term or summer break.

What affects the quote in Ayres End
The diagnosis comes before the price. We look at:
- Any permits to work or inductions
- The condition we find in the survey
- Working hours and out-of-hours timing
- How many systems or sites are involved
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
What to send for a quote
We can often survey from photos. The most useful are:
- Problems your staff have spotted
- Any previous report or certificate
- The times we could work without disrupting the site
- A few general shots of the system
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
When something else is needed
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- 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)
If in doubt, call 0345 646 2711, or email photos and we’ll say what we think.
