Ductwork cleaning around South Mimms
The FSA’s data shows about 4 pubs, bars and clubs registered within 1.5 miles or so of the middle of South Mimms. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Food hygiene inspections in South Mimms are the job of Hertsmere council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. South Mimms 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 St Giles' CofE Primary School, an extract clean fits neatly into a half-term or summer break. A hall kitchen that only cooks for events, whether near Church of St Giles or elsewhere in South Mimms, still needs its extract cleaned, just less often.

About our ductwork cleaning in South Mimms
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it and a fire in the duct can spread through the building. We clean it from the inside, through access panels, to BESA TR19® Grease. If you’re dealing with duct runs that can’t be reached and an insurer asking for TR19 evidence, we can put it right.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Tell us if grease leaks from the ductwork
- Keep your cleaning records together
- Keep the fan on while anything is cooking
- Ask for a grease thickness test if the kitchen gets busier
The report names every part of the duct that couldn’t be reached and why. We can fit access panels so those sections are cleaned next time.
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.
What affects the cost of ductwork cleaning
We don’t publish a price list, because sites vary so much. What we look at:
- How big the system is
- Working hours and out-of-hours timing
- Site requirements such as sign-in and permits
- How many systems or sites are involved
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 will price it together.
What we need to know
You do not need the technical terms. It helps if you can send:
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- Any previous report or certificate
- The site address and the type of premises
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
What happens if it’s left?
There’s no law that names TR19. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. In a place like South Mimms, ductwork and fans are easy to forget until something goes wrong.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, call us on 0345 646 2711 or send us an email for straight advice and a fixed quote.

Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a shift or more, depending on the length of the runs and the number of access points. Seeing the system in pictures first means the trip to South Mimms can be planned properly.
- We start by working out how the duct runs and where it can be opened.
- Set points along the runs are tested for grease.
- We open the panels and scrape out the heaviest grease.
- 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.
Preparing for the visit
- Let us know when the site is closed or quiet
- Find the previous report, if there is one
- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
To help us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711 or drop us a line.

Questions from South Mimms
Which environmental health team covers South Mimms?
The local authority for South Mimms is Hertsmere council, and its environmental health team does the inspecting. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Do you do school kitchen extract cleaning in South Mimms in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of South Mimms. Just phone us on 0345 646 2711 or drop us a line with your term dates and we will plan around them.
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 a fixed quote usually follows within one working day. If photos are not enough, we will survey first.
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 does not spread.
Do you cover South Mimms?
Yes. Our area takes in London and the counties of South East England, and that includes South Mimms.
What should I send you?
Some photos and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
How can I tell if my extract ducts are dirty?
Start with the date of the last clean. If it’s overdue, or there is not one, a clean is due, and grease readings will confirm how urgent it is.
How often should kitchen ducts be cleaned?
The minimum depends on how long the kitchen cooks each day: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Measured grease sets the real interval.

Other services in South Mimms
Do you need ductwork cleaning in South Mimms?
A duct with too few access doors cannot be fully cleaned. Stretches with no way in may never have been touched, and grease there keeps thickening unseen.
Any of these means the system needs a check-up:
- An insurer asking for TR19 evidence
- Thick crusts of old grease along the duct
- Duct runs that cannot be reached
- Thick deposits at the bottom of a vertical duct
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Shenley Hospital is the nearest hospital to South Mimms, about 2.7 miles west.
