Questions from Brentford
Is parking a problem for work in Brentford?
Tell us where a van can stop near your site in Brentford, and about any building rules on loading. Much of our London work is done overnight, which helps.
Who is the fire and rescue service for Brentford?
London Fire Brigade is the fire and rescue service for Brentford. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How long does ductwork cleaning take?
A short duct can be cleaned in a few hours, while long ducts and tall risers can need more than one visit. Visits are planned out of hours.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
Where does the waste go?
It leaves the site with us at the end of the visit. During the work, it’s contained to keep the area clean.
Can you fit access panels in our ductwork?
Yes, extra panels can be fitted. That lets the next clean reach sections that were missed, and the report will show where they’re needed.
Can you clean ductwork with no access panels?
We clean everything we can reach and record what we can’t. Fitting extra access panels is the usual answer, and we can do that for you.
What’s TR19?
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, while TR19® Air covers other supply and extract ductwork.
Ductwork cleaning in Brentford, done properly
Duct cleaning is the hardest part of an extract clean, and the part most often skipped. Sections with no way in can go uncleaned for years. We open up every reachable section and record any we can’t reach, so you know exactly where you stand. Common call-outs are for grease pooling at the foot of the riser and a rancid smell from the extract duct, on access panels, bends and junctions and horizontal duct runs.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. In Brentford, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What a clean won’t put right
Not every problem is solved by ductwork cleaning, and we’ll tell you before any work starts. It will not put right:
- Faulty fire dampers
- Leaking duct joints that need repair
- An extract fan that has stopped working
If you are not sure, just call 0345 646 2711 or email us and we’ll give you a straight answer.

What affects the quote in Brentford
The diagnosis comes before the price. We look at:
- The times the site is available
- Site requirements such as sign-in and permits
- Whether it’s a one-off visit or part of a schedule
- How many systems or sites are involved
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
What to send for a quote
You do not need the technical terms. Just send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Where the site is and what kind of site it is
- The times we could work without disrupting the site
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711 or send us an email.
How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a few hours for a short run, longer for long runs and tall risers. In Brentford, as across London, we normally work overnight or at weekends and hand the site back ready to open.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- 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
- Name a contact who can let us in at the agreed time
- Tell us where we can park and unload
- Move anything stored near the system
Ask for a quote
Photos are the quickest way to a quote: 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
When to call us in Brentford
Air cools as it moves away from the canopy. Cooling air drops its grease onto the inside of the duct, so duct runs keep collecting grease long after the canopy.
Any of these means the system needs a check-up:
- Grease seeping out of the duct seams
- Ductwork that has never been cleaned
- Hardened, baked-on grease in long horizontal runs
- A grease test showing the duct is overdue
Volunteers running a hall kitchen near Congregational Church, or anywhere in Brentford, may not know when the extract was last cleaned, and a grease test settles it.
What to look for in a quote
- What’s included in the scope, part by part
- When the next visit should be, and why
- How areas they can’t reach will be recorded
- Whether VAT is included
Landlords, agents and facilities managers
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Facilities teams in offices, schools and healthcare sites book us too in Brentford and across Greater London. Larger estates can be phased building by building to keep disruption down.
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.
Multi-storey and shared buildings
In a shared building, the duct links the kitchen to other spaces, so the responsible person has more reason to keep it clean. The paperwork suits landlords and managing agents.
Grease, kitchens and Brentford
The FSA’s data shows about 72 pubs and bars and about 12 hotels and B&Bs registered across Brentford and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Brentford is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Food hygiene inspections in Brentford are the job of Hounslow council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
If you cook for passing trade around Brentford station, the extract can be cleaned between your last and first customer. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; West Middlesex University Hospital is the nearest hospital to Brentford, about 1.4 miles south-west.

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
