Duct cleaning in Keeres Green
Ductwork cleaning in Keeres Green from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Smells of old cooking grease from the ductwork
- Years of grease along the duct floor
- Grease seeping out of the duct seams
Ductwork cleaning in Keeres Green, done properly
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Every horizontal run and vertical riser collects grease along the way and a fire in the duct can spread through the building. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. If you have ductwork that has never been cleaned and proof of duct cleaning for the insurer, we can put it right, from access panels, horizontal duct runs and bends and junctions onwards.
For a kitchen in or near Keeres Green, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What affects the cost of ductwork cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours and out-of-hours timing
- Site rules, permits and inductions
- Whether we need access equipment or extra panels
- The size of the system
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.
What we need to know
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- Wide pictures of the system and the area around it
- Problems your staff have spotted
Getting a quote doesn’t take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Questions from Keeres Green
Will you come out to Keeres Green?
Yes, we work in villages as well as towns, and Keeres Green is covered. Photos of the system and directions to the site help us plan the visit.
Do you work overnight in Keeres Green?
Yes, nights and weekends are routine for us. The work in Keeres Green can fit around your hours. Your opening times are the first thing we ask for.
Are you fully insured?
Yes. We carry full insurance, and we have been trading since 2009.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
Who is responsible for fire safety on the premises?
It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
What shows that the ducts need a clean?
We measure it. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
Keeping the system healthy
So the system stays in good health:
- Report any grease dripping from duct joints
- Diarise the next duct clean
- Ask for a grease thickness test if the kitchen gets busier
- Never cook with a filter missing
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
Watch for warning signs between cleans: grease leaking from duct joints, smells, or a fan that sounds rough. A grease thickness test can confirm whether a spot clean is needed.
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.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
The process
Night work is normal for us. 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 few hours for a short run, longer for long runs and tall risers. A quick note on how to find the site and where to park makes a visit to Keeres Green run smoothly.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Make sure someone can let us in and lock up afterwards
- Dig out any earlier paperwork for the system

Grease, kitchens and Keeres Green
Essex County Fire and Rescue Service covers Keeres Green. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Keeres Green is about 27 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.
Where a hall near Parish Church of St Michael and All Angels, or anywhere in Keeres Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Term dates shape school work: for a school like Rodings Primary School, an extract clean fits neatly into a half-term or summer break.
Keeres Green is about 8 miles south-east of Bishop's Stortford, in Essex. Wherever you are in the CM6 postcode area, we cover ductwork cleaning for commercial sites. We cover 644 places across Essex, from busy centres to quieter spots. Our Chelmsford page covers sites nearby, about 9 miles away.

Do you need ductwork cleaning in Keeres Green?
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 something like this:
- Thick crusts of old grease along the duct
- Fat dripping from the ductwork
- A rancid smell from the extract duct
- Grease pooling at the foot of the riser
Historic houses near Keeres Green, such as Barrington Hall about 3.4 miles north-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

How the job changes from site to site
Multi-storey and shared buildings
A fire in a duct in a shared building can affect far more than one kitchen, which makes keeping it clean all the more important. Your certificate and report give building managers the record they need.
Attenuators and discharge
Near the discharge, the air has cooled the most, so it can collect more grease than expected. We include it in the clean and the readings.
