Ductwork cleaning in Letty Green, done properly
Many ducts were installed with too few access doors. TR19 calls for any section we couldn’t reach to be recorded, and we can fit new access panels so it’s cleaned next time. It’s better to know than to assume. Typical jobs include grease pooling at the foot of the riser and grease leaking from duct joints, across access panels, bends and junctions and attenuators.
In a village or hamlet like Letty Green, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes from a few hours to more than one visit, depending on duct length and access. Somewhere like Letty Green, lanes, gates and parking are worth mentioning in advance.
- We start by working out how the duct runs and where it can be opened.
- Set points along the runs are tested for grease.
- We open the panels and scrape out the heaviest grease.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Getting ready for the visit
- Mention any parking or loading restrictions
- Have your last certificate or report to hand
- Clear loose items from the work area

Related advice
Common problems we fix in Letty Green
A duct with too few access doors can’t be fully cleaned. Sections between panels go uncleaned, sometimes since the system was installed, and grease there keeps thickening unseen.
Any of these means the system needs a check-up:
- Stale grease odours from the duct
- An insurer asking for TR19 evidence
- Grease leaking from duct joints
- A grease test showing the duct is overdue
Where a hall near St John's Church, or anywhere in Letty Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Why deal with it now?
A fire in a greasy duct is hard to reach and hard to stop. The duct can carry it to rooms, floors or roof spaces well away from the kitchen, so cleaning the duct is as important as cleaning the hood. A planned visit to Letty Green is easier to arrange than an emergency callout.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.

What the work involves, part by part
Access panels
We can fit new access panels where the duct needs them, so the next clean reaches more of the system. The survey shows where they’re needed.
Attenuators and discharge
Near the discharge, the air has cooled the most, which can mean heavier deposits. We include it in the clean and the readings.
Fixed quotes for ductwork cleaning in Letty Green
Every site gets its own quote. This is what makes a difference:
- The condition of the system
- How big the system is
- Any permits to work or inductions
- When the work can happen, such as evenings, overnight or weekends
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711, or send details by email, and we’ll explain what it covers.
Asking for a quote
Before you ask for a quote, gather:
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
- Your opening hours and when the area is out of use
- Problems your staff have spotted
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Kitchen extracts in Letty Green
Letty Green is about 20 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours. The fire and rescue service for Letty Green is 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.

Letty Green questions
