How we handle ductwork cleaning in Great Hallingbury
Duct cleaning is the hardest part of an extract clean, and the part most often skipped. Without enough access panels, long stretches can go years without being touched. We open up every reachable section and record any we cannot reach, so you know exactly where you stand. The work covers bends and junctions, attenuators and horizontal duct runs, and people most often call us about a duct clean needed for an insurer and grease leaking from duct joints.
Somewhere as small as Great Hallingbury, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

How it works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes from a few hours to more than one visit, depending on duct length and access. The timing of a visit to Great Hallingbury is set by you, and the travel is our side of the planning.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- Access panels are opened and heavy deposits scraped out by hand.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Post-clean readings and photos go into the report, with any unreachable section listed.
How to prepare
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend
- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Between visits
To keep the system working properly between visits:
- Have the grease measured if cooking hours go up
- Make sure filters are seated properly
- Don’t block access panels with shelving or stock
- Store the certificate with the fire risk assessment
Access panels are closed and sealed back up after cleaning, and the surrounding area is left clean. Grease and dirty water are contained and removed.
Book the next duct clean before the date passes. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
Your questions about ductwork cleaning in Great Hallingbury
Can you work in Great Hallingbury outside opening hours?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Great Hallingbury needn’t be disturbed. Just give us a ring on 0345 646 2711 or send us an email with your opening times and we will plan around them.
Do you work in villages like Great Hallingbury?
Yes, Great Hallingbury is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
What’s involved in cleaning extract ducts?
We get into the duct through its access panels. Thick deposits are removed by hand before degreasing, such as degreasers, hot water or steam.
Can extra access doors be added to the duct?
Yes, we fit access panels where the duct needs them. It means more of the duct can be cleaned next time, and the report will show where they’re needed.
Who is responsible for fire safety on the premises?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
Do I get a certificate for ductwork cleaning?
A full system clean comes with a TR19 certificate and a photo report. The report shows readings, pictures and any sections we couldn’t reach.
How long does it take to clean extract ducts?
Allow a shift or more, depending on the length of the runs and the number of access points. We’ll confirm the time when we quote.
What if part of the duct can’t be reached?
Without a way in, a section can’t be cleaned properly. We record those sections on the report and can fit access panels.
Why act early in Great Hallingbury
BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean straight away. Leaving the duct makes those limits harder to keep to. It’s simpler to plan the work at Great Hallingbury now than to arrange it in a hurry later.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before work begins.

When to call us in Great Hallingbury
Slow air leaves the most grease behind. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
The symptoms we are asked about most are:
- Thick crusts of old grease along the duct
- Gaps where access panels were never fitted
- High readings at a recent grease test
- Heavy grease at the base of a riser
If your kitchen is in a listed or historic building, like the houses around Great Hallingbury (Barrington Hall is about 2.6 miles south-east), fitting access panels needs care.
Questions to ask before you book

- Which accreditations they hold, and whether you can check them
Kitchen extracts in Great Hallingbury
Food Standards Agency records include about 4 bars, pubs and nightclubs and about 4 hotels and guest houses within 1.5 miles or so of the middle of Great Hallingbury. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Great Hallingbury is covered by Essex County 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. Food hygiene inspections in Great Hallingbury are the job of Uttlesford council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
Term dates shape school work: for a school like Thorn Grove Primary School, an extract clean fits neatly into a half-term or summer break.

What affects the cost of ductwork cleaning
Before we fix a price, we need to know a few things. We look at:
- The times the site is available
- Parking and loading at the site
- The condition of the system
- How easy every part is to reach
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
What to send for a quote
What to send for a quote:
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide pictures of the system and the area around it
- Any previous report or certificate
To help us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711 or send us an email.
What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Part by part
Access panels
Panels have to seal properly once they’re closed so the duct stays tight. A damaged panel is noted on the report.
Attenuators and discharge
Attenuators, where fitted, quieten the extract, but they can hold grease in their linings. We clean what can be reached and note anything that can’t.
