What affects the quote in Pin Green
Some jobs are bigger than they look, and some smaller. The main factors:
- When the work can happen, such as evenings, overnight or weekends
- How big the system is
- Parking and loading at the site
- What state the system is in
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.
What to send for a quote
What to send for a quote:
- The paperwork from the last visit, if you have it
- The times we could work without disrupting the site
- The postcode and the type of business
- The roof, plant room or outside wall the system runs to
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To start, give us a ring on 0345 646 2711, or email photos.
Ductwork cleaning for kitchens and businesses in Pin Green
We’ve been trading since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, with each certificate issued through the BESCA portal. Common call-outs are for smells of old cooking grease from the ductwork and a duct nobody has opened in years, across access panels, horizontal duct runs and bends and junctions.
In a smaller place like Pin Green, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
A written report with photos follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Honest limits
It’s worth knowing the limits before booking:
- A worn-out fan that needs replacing
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
- Fire dampers that don’t close (they need testing and remedials)
Not sure which it is? You can call 0345 646 2711, or email photos and we’ll tell you honestly.
What the work covers
- Bends and junctions
- Access panels
- Multi-storey ducts
- Attenuators
- Vertical risers
- Horizontal duct runs
Do you need ductwork cleaning in Pin Green?
Grease settles fastest where the air slows down. 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 include:
- Gaps where access panels were never fitted
- Grease leaking from duct joints
- A rancid smell from the extract duct
- Duct runs with no cleaning record
If you run catering at a historic house or estate in the area (Aston Bury is about 3 miles south-east), event kitchens in older buildings often have awkward duct runs that need planning.

- How VAT is shown on the quote
What happens if it’s left?
A partly blocked duct slows the airflow. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy, and grease may start to leak from joints. When a site near Pin Green shuts unexpectedly, the people who rely on it notice at once.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before we start.

How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, and that takes a shift or more, depending on the length of the runs and the number of access points. Your opening hours decide when we come to Pin Green, not ours.
- Diagnosis: a survey of the duct’s route, size and access.
- You get a fixed price before work starts.
- Each section is cleaned in turn through its access panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, photos and a next clean date.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site
- Clear loose items from the work area
How to get a quote
Some systems can be priced from pictures; 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.

Pin Green: your questions answered
Is Pin Green within the area you cover?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Which fire and rescue service is responsible for Pin Green?
Pin Green is in the area of Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can you quote from photos?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
Do you work with multi-site operators?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and leave the area clean.
How long does it take to clean extract ducts?
It takes a few hours for a short run, longer for long runs and tall risers. The survey tells us how long your duct needs.
Pin Green kitchens: local notes
Look up Pin Green on the FSA’s food hygiene register and you’ll find about 96 cafés, restaurants and staff canteens and about 56 takeaways and sandwich shops within 1.5 miles or so of the middle of Pin Green. Behind every canopy among them is a run of ductwork that collects grease out of sight. Fire safety in Pin Green falls to 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. Kitchens in Pin Green get their food hygiene inspections from Stevenage council. 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.
Volunteers running a hall kitchen near Church of Saint Nicholas, or anywhere in Pin Green, may not know when the extract was last cleaned, and a grease test settles it. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Lister Hospital is the nearest hospital to Pin Green, about 1.2 miles north-west.

Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep grease filters clean and fitted whenever you cook
- Keep to the interval on the report
- Run the extract fan throughout service
- Ask for a grease thickness test if the kitchen gets busier
When the duct is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
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.
Part by part
Multi-storey and shared buildings
A fire in a duct in a shared building can affect far more than one kitchen, so the responsible person has more reason to keep it clean. The paperwork suits landlords and managing agents.
Horizontal duct runs
Grease settles on the floor of a flat duct run. Thick deposits are scraped out by hand before degreasing, then the walls and roof are cleaned too.
