Do you need ductwork cleaning in Batford?
Grease in a duct running from a kitchen in Batford is as much a fire risk as in any building. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
Clients typically contact us after spotting something like this:
- Fat dripping from the ductwork
- Heavy grease at the base of a riser
- Duct runs that can’t be reached
- Proof of duct cleaning for the insurer
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Batford is St Albans City Hospital, about 4.1 miles south.
Questions to ask before booking
- When they can work, and whether that is outside your opening hours
- What happens if part of the system cannot be accessed
- Proof of accreditation you can verify
- Exactly which parts of the system are covered
How we handle ductwork cleaning in Batford
The ductwork is where an extract clean is won or lost. Without enough access panels, long stretches can go years without being touched. Each section we can reach is cleaned, and any we can’t is written down, so you know exactly where you stand. Typical jobs include an insurer asking for TR19 evidence and grease seeping out of the duct seams, on access panels, multi-storey ducts and vertical risers.
In a smaller place like Batford, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Part by part
Attenuators and discharge
The last section of duct before the discharge is often the coolest, so it can collect more grease than expected. It’s tested and cleaned along with the rest.
Vertical risers
Risers carry the extract up through the building to the roof. Grease runs down the walls and gathers at the base, so the base is one of our test points.
Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Run the extract fan throughout service
- Check readings when the menu changes
- Leave a way through to the access panels
- Tell us if grease leaks from the ductwork
Every panel we open is refitted when we finish, and the surrounding area is left clean. Waste grease and water are taken away.
The less grease gets past the canopy, the cleaner the duct stays. Keep the filters clean, well fitted and in place whenever you cook.
Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
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 if it’s left?
Dealing with the ductwork in Batford now beats dealing with it after a problem. It takes a shift or more, depending on the length of the runs and the number of access points, done out of hours so the kitchen keeps cooking. Systems on quieter sites still build up dirt and wear, just more slowly.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, ring 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.

Batford kitchens: local notes
The Food Standards Agency lists about 21 bars, pubs and nightclubs as registered food businesses across Batford and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. It’s St Albans City council that sends environmental health officers to food businesses in Batford. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Batford is covered by Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
A kitchen near Harpenden station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. For schools such as Crabtree Infants' School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

What a clean will not put right
In fairness, there are a few things this work will not fix:
- An extract fan that has stopped working
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we’ll tell you honestly before booking.

Batford: your questions answered
Do you work overnight in Batford?
Yes. We work evenings, overnight and at weekends. That way a site in Batford does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Who inspects food businesses in Batford?
Food hygiene inspections in Batford are carried out by St Albans City council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Will I get a report after the ducts are cleaned?
You get a photo report with before and after pictures, plus a TR19 certificate when the whole system is cleaned. File them with the fire risk assessment.
How often should kitchen ducts be cleaned?
The minimum depends on how long the kitchen cooks each day: 3-monthly for heavy use, 6-monthly for moderate and 12-monthly for light use. Grease readings may show it needs doing sooner.
What do you need from me for a quote?
A short description and a few photos plus the address and your hours. If we need more, we will ask.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
How can I tell if my extract ducts are dirty?
We measure it. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
Are you insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
How the visit works
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a shift or more, depending on the length of the runs and the number of access points. Tell us when your site near Batford is quiet and the visit will be booked for then.
- We map the duct route and check where the access panels are.
- We measure grease thickness at set points before cleaning.
- Access panels are opened and heavy deposits scraped out by hand.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Post-clean readings and photos go into the report, with any unreachable section listed.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
