Redbourn ductwork cleaning
We cover Redbourn for ductwork cleaning. Out-of-hours visits, a fixed quote and a written report with pictures on every job.
- Proof of duct cleaning for the insurer
- Grease seeping out of the duct seams
- Readings above 200 microns from a grease thickness test
What affects the cost of ductwork cleaning
We quote each job individually. These are the things that affect it:
- Whether it’s a one-off visit or part of a schedule
- How big the system is
- Site requirements such as sign-in and permits
- How easy every part is to reach
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
Getting a quote doesn’t take long. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
About our ductwork cleaning in Redbourn
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 that’s where a kitchen fire can travel. We clean it from the inside, through access panels, to BESA TR19® Grease. The work covers multi-storey ducts, access panels and attenuators, and the jobs we see most are years of grease along the duct floor and sections of duct with no access panels.
Kitchens around a place like Redbourn are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
We’ve 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 carry full insurance.

How the visit works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes from a few hours to more than one visit, depending on duct length and access. Around Redbourn, access is typically simpler than in a town centre, though gates and roof access are worth mentioning.
- 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.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Arrange a key holder or contact on site
- Mention any sign-in, permit or induction we need
Getting a quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before any work starts.

Do you need ductwork cleaning in Redbourn?
A vertical riser can run up several floors. 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.
Common reasons sites call us include:
- High readings at a recent grease test
- Grease leaking from duct joints
- Proof of duct cleaning for the insurer
- Years of grease along the duct floor
School kitchens, at schools like Redbourn Primary School for example, are normally cleaned in the holidays so no lunches are lost.

Kitchen extracts in Redbourn
Look up Redbourn on the FSA’s food hygiene register and you’ll find about 8 restaurants, cafés and canteens across Redbourn and its immediate surroundings (about a mile and a half). Behind every canopy among them is a run of ductwork that collects grease out of sight. Kitchens in Redbourn get their food hygiene inspections from St Albans City council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Redbourn 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.
Church and community hall kitchens, near Mount Zion Evangelical Church or anywhere around Redbourn, are easy to forget, but their extracts collect grease like any other. Healthcare kitchens, like those at hospitals such as St Albans City Hospital (about 3.6 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands.
Redbourn is about 2 miles south-west of Harpenden, in Hertfordshire. Every kind of commercial site in Redbourn, we can take on ductwork cleaning. We can work out of hours so the site keeps running. We cover 381 places across Hertfordshire, large and small. There’s also a page for Milton Keynes, about 23 miles away.
We work across AL3 for ductwork cleaning and the roads nearby. Local streets include High Street, The Square and Lords Meadow, all of which we cover for ductwork cleaning. Other places close to Redbourn include Holtsmere End (2 miles south-west), Highfield (3 miles south-west), Westwick Row (4 miles south), Leverstock Green (4 miles south) and Adeyfield (4 miles south-west). Within a short drive, we also cover Watford (9 miles south), Hemel Hempstead (4 miles south-west), Stevenage (12 miles north-east), St Albans (4 miles south-east), Welwyn Garden City (9 miles east) and Hitchin (12 miles north-east).
Around Redbourn
Locally, jobs take us to businesses close to The Bell And Shears Public House, Roundwood Park School and Rothamsted Park, among other places. The nearest railway station is Harpenden station, about 2.3 miles north-east of the centre. A little further out are Redbourn Museum (under half a mile south-east) and St Albans City Hospital (3.6 miles south-east). Not far away are Grebe House Wildlife Garden and Verulamium Lake.
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Leave it or put it right?
Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. Anywhere that reaches 500 microns or more needs immediate spot cleaning. Putting off the clean only pushes readings higher. A visit arranged in advance is far less disruptive than a callout on a busy day.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Keep grease filters clean and fitted whenever you cook
- Store the certificate with the fire risk assessment
- Leave a way through to the access panels
- Ask us about extra access panels where sections cannot be reached
You will have a recommended date for the next clean, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
The less grease gets past the canopy, the cleaner the duct stays. Keep the filters clean, well fitted and in place whenever you cook.
Questions from Redbourn
Which fire service covers Redbourn?
Redbourn is in the area of Hertfordshire Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Who inspects food businesses in Redbourn?
Food hygiene inspections in Redbourn are carried out by St Albans City council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you survey before quoting?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
How can I tell if my extract ducts are dirty?
Drips, smells and weak extraction are clues, but the only sure way is to measure. Grease thickness testing shows exactly where the duct stands.
What happens if there aren’t enough access panels?
We clean everything we can reach and record what we cannot. Fitting extra access panels is the usual answer, and we can do that for you.
What happens if you can’t reach some of it?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Is Redbourn in your area?
Yes. We cover Redbourn and the rest of Hertfordshire, within our South East and London area. For a fixed quote, give us a ring on 0345 646 2711, or send details by email.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
