Ductwork cleaning around Sipson
Food Standards Agency records include about 17 pubs and bars and about 18 hotels and B&Bs within 1.5 miles or so of the middle of Sipson. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier. Fire safety in Sipson falls to London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Bursars and site managers at schools such as Cherry Lane Primary School tend to book extract cleaning for when the kitchen is empty. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Sipson is Harlington, about less than half a mile south.

Ductwork cleaning for kitchens and businesses in Sipson
Once air leaves the canopy, it travels through ductwork that most people never see. 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 bends and junctions, attenuators and access panels, and people most often call us about readings above 200 microns from a grease thickness test and gaps where access panels were never fitted.
In a London area like Sipson, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what ductwork cleaning won’t do:
- Fire dampers that do not close (they need testing and remedials)
- A failed fan motor at the end of the duct (a fan repair job)
- Leaking duct joints that need repair
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.

In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.

Why act early in Sipson
Old grease in a duct for a kitchen in Sipson does not stay soft. It bakes into a hard layer that takes far longer to remove, so the later the clean, the bigger the job. For a site in Sipson, fitting the work in overnight now is far easier than closing at short notice later.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.

Landlords, agents and facilities managers
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Signs you need ductwork cleaning in Sipson
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.
Look out for any of the following:
- A grease test showing the duct is overdue
- Thick deposits at the bottom of a vertical duct
- An insurer asking for TR19 evidence
- Hardened, baked-on grease in long horizontal runs
Osterley House, about 4.3 miles east, is one of the historic houses near Sipson; if you run event catering at a venue like that, cleans can be booked between functions.
Questions to ask before booking

Sipson questions
What do you need to know about parking in Sipson?
A loading bay, a visitor permit or off-street space near the site in Sipson makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Can you come to Sipson after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
Can you fit access panels in our ductwork?
Yes, we fit access panels where the duct needs them. That lets the next clean reach sections that were missed, and the report will show where they’re needed.
Are you fully insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How long will the duct clean take?
It depends on the length of the duct, the number of access panels and how much grease there is. Typically it takes from a few hours to more than one visit, depending on duct length and access.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
What happens if there aren’t enough access panels?
Ductwork needs access to be cleaned. Those parts are listed, and we can install panels so they’re reached next time.
What we do, step by step
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a few hours for a short run, longer for long runs and tall risers. A name and number for whoever controls access to the building in Sipson saves time on the night.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Preparing for the visit
- Let us know about parking and loading
- Make sure equipment near the work can be switched off and left to cool
- Move anything stored near the system
Getting a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Different parts, different methods
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.
Bends and transitions
Wherever the duct turns or changes size, grease builds up. Slowing air leaves grease behind, so we clean these points carefully.
