About our ductwork cleaning in Sarratt
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. If you have a grease test showing the duct is overdue and grease pooling at the foot of the riser, we can put it right.
In a small place like Sarratt, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
We’ve 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.

Sarratt questions
Which council inspects kitchens in Sarratt?
The local authority for Sarratt is Three Rivers 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.
Can you come to Sarratt after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Sarratt doesn’t have to lose a day’s trading. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
Do I get a certificate for ductwork cleaning?
A photo report, with readings and before and after pictures, plus a TR19 certificate for a full system clean. It also gives a recommended next clean date.
How can I tell if my extract ducts are dirty?
We measure it. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
What happens if there are not enough access panels?
Ductwork needs access to be cleaned. We record those sections on the report and can fit access panels.
How much does ductwork cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, typically ready within one working day.
Which accreditations do you hold?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Why it’s worth doing now in Sarratt
BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. Anywhere that reaches 500 microns or more needs immediate spot cleaning. Leaving the duct makes those limits harder to keep to. It’s simpler to plan the work at Sarratt now than to arrange it in a hurry later.
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

What we are called out for in Sarratt
Slow air leaves the most grease behind. Flat runs, bends, reducers and the base of risers are the usual hotspots, and those are the points we pay most attention to.
Clients typically contact us when they notice something like this:
- Grease pooling at the foot of the riser
- Smells of old cooking grease from the ductwork
- Fat dripping from the ductwork
- Duct runs with no cleaning record
Where a hall near Church of the Holy Cross, or anywhere in Sarratt, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Ductwork cleaning in Sarratt: the local picture
The FSA’s food hygiene register includes about 6 pubs, bars and clubs within 1.5 miles or so of the middle of Sarratt. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Sarratt get their food hygiene inspections from Three Rivers council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Sarratt falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you run catering at a historic house or estate in the area (Chenies Manor House is about 1.8 miles west), event kitchens in older buildings often have awkward duct runs that need planning. Term dates shape school work: for a school like Sarratt Church of England Primary School, an extract clean fits neatly into a half-term or summer break.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what ductwork cleaning won’t do:
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- A failed fan motor at the end of the duct (a fan repair job)
- Duct sealed behind fixed ceilings or walls
If you’re not sure, just call 0345 646 2711 or drop us a line and we will give you a straight answer before booking.

Fixed quotes for ductwork cleaning in Sarratt
Before we fix a price, we need to know a few things. We look at:
- How easy every part is to reach
- The times the site is available
- One-off work versus a regular cycle
- Whether several sites go on one quote
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before any work starts.
Asking for a quote
You don’t need the technical terms. Just send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before we start.
Between visits
Good habits slow the build-up between visits. Our tips:
- File each certificate and photo report in the maintenance log
- Ask us about extra access panels where sections cannot be reached
- Tell us if grease leaks from the ductwork
- Keep grease filters clean and fitted whenever you cook
The report gives a recommended next clean date, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Some signs mean the duct needs attention sooner: drips from the ductwork, stale smells or a noisy fan. Testing will show whether any section has reached 500 microns.
What we do, step by step
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 from a few hours to more than one visit, depending on duct length and access. Visits to a village like Sarratt are booked in advance, at a time that suits whoever runs the site.
- Diagnosis: a survey of the duct’s route, size and access.
- You get a fixed price before work starts.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, photos and a recommended next clean date complete the job.
Preparing for the visit
- Let us know about permits to work or site inductions
- Tell us the best time to work, such as after service or at a weekend
- Mention any parking or loading restrictions
Get a fixed quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Advice
What the work involves, part by part
Multi-storey and shared buildings
In a shared building, the duct links the kitchen to other spaces, which makes keeping it clean all the more important. Your certificate and report give building managers the record they need.
Vertical risers
Risers carry the extract up through the building to the roof. Grease collects on the walls and at the foot of the riser, so the base is one of our test points.
