Ductwork cleaning in Cornish Hall End, done properly
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it, and that is where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. Common call-outs are for duct runs with no cleaning record and grease seeping out of the duct seams, on bends and junctions, attenuators and access panels.
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. Access, parking and timings are agreed before the day.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Your questions about ductwork cleaning in Cornish Hall End
Who inspects food businesses in Cornish Hall End?
That is Braintree council, whose environmental health officers carry out food hygiene inspections in Cornish Hall End. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can you come to Cornish Hall End after we close?
Yes, out-of-hours work is a big part of what we do. The work in Cornish Hall End can fit around your hours. Your opening times are the first thing we ask for.
How is kitchen extract ductwork cleaned?
Through access panels along the duct. 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.
What shows that the ducts need a clean?
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.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Will we have to shut during the visit?
Not usually. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits so parts stay in use.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare in Cornish Hall End and across Essex. Larger estates can be phased building by building to keep disruption down.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
What we are called out for in Cornish Hall End
Risers carry the extract up through the building. 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.
Clients normally contact us when they notice one of these:
- High readings at a recent grease test
- Duct runs that can’t be reached
- A duct nobody has opened in years
- Proof of duct cleaning for the insurer
A TR19® clean in Cornish Hall End does not stop at the filters: the plenum, ductwork, fan and discharge are cleaned too.

- Ductwork that was poorly designed

- Leaking duct joints that need repair
Not sure which it is? You can call us on 0345 646 2711 or send us an email and we’ll tell you honestly before you book.

- Horizontal duct runs
- Access panels

Leave it or put it right?
Old grease in a duct for a kitchen in Cornish Hall End does not stay soft. It bakes into a hard layer that takes far longer to remove, which makes each delayed clean a bigger one. Systems in rural buildings are often out of sight and out of mind.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.

What else we do in Cornish Hall End
The process
There are three stages on the day: 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 pictures. Most of the time goes on the work itself, and that takes a few hours for a short run, longer for long runs and tall risers. Visits to a village like Cornish Hall End are booked in advance, at a time that suits whoever runs the site.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Plan for cooking equipment or plant to be off before we arrive
- Make sure someone can let us in and lock up afterwards
Ask for a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
