Ductwork cleaning in Westwick Row
We treat ductwork like a doctor treats arteries: find the blockages, clear them, then check the flow is right. Readings taken before and after show the difference, alongside before and after photos. The work covers multi-storey ducts, attenuators and access panels, and people most often call us about grease pooling at the foot of the riser and gaps where access panels were never fitted.
Work in a small place like Westwick Row starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
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’re fully insured.

Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
Your questions about ductwork cleaning in Westwick Row
Can school kitchens in Westwick Row be cleaned in the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 12 schools and colleges with food registrations within roughly a mile and a half of Westwick Row. Just give us a ring on 0345 646 2711 or email us with your term dates and we will plan around them.
Can you work in Westwick Row outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Westwick Row keeps running as normal. When you give us a ring on 0345 646 2711 or drop us a line, mention when the site is quiet.
Do you install duct access panels?
Yes, we do. The survey or clean shows where sections couldn’t be reached, and we can fit them so those sections are cleaned in future.
How much does ductwork cleaning cost in Westwick Row?
It depends on the site, so we quote each one individually. To get one, call 0345 646 2711 or send us an email and tell us about the site and its opening hours.
Who is the responsible person?
In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.
What’s involved in cleaning extract ducts?
Each section is cleaned through its own panel. Grease is scraped out first, then degreased, with readings taken before and after.
What does TR19 mean?
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 isn’t law, but it’s the benchmark.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
Grease, kitchens and Westwick Row
The FSA’s food hygiene register includes about 11 pubs, bars and clubs within roughly a mile and a half of the centre of Westwick Row. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Kitchens in Westwick Row get their food hygiene inspections from Dacorum council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Westwick Row is covered by 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.
If your kitchen is in a listed or historic building, like the houses around Westwick Row (Batchwood Hall is about 3.1 miles north-east), fitting access panels needs care. Term dates shape school work: for a school like Leverstock Green Church of England Primary School, an extract clean fits neatly into a half-term or summer break.

Around Westwick Row
Around Westwick Row, our work takes us to kitchens and buildings near Longdean School, among other places. For rail, the closest station is Apsley station, about 2.1 miles south-west of the centre. A little further out are Village Arcade St Albans (3.4 miles east) and Hemel Hempstead Hospital (2.1 miles west). Not far away are Verulamium Lake and Long Deans.
Aftercare tips
How long the results last depends on use and care. We suggest:
- Leave a way through to the access panels
- Ask us about extra access panels where sections cannot be reached
- Never cook with a filter missing
- File each certificate and photo report in the maintenance log
You’ll have a recommended date for the next clean, based on the readings and your daily cooking hours, in line with BESA guidance.
Keep to the cleaning interval on the report. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
Common problems we fix in Westwick Row
A vertical riser can run up several floors. Grease clings to the walls and can run down to the base, where it can pool. Access along its height is needed to clean it properly.
Any of these means the system needs a check-up:
- Duct runs that can’t be reached
- High readings at a recent grease test
- Years of grease along the duct floor
- Ductwork that has never been cleaned
A hall kitchen that only cooks for events, whether near Church of Holy Trinity or elsewhere in Westwick Row, still needs its extract cleaned, just less often.

When something else is needed
A few issues sit outside what this work can do:
- Faulty fire dampers
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
- A worn-out fan that needs replacing

What else we do in Westwick Row
How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes a shift or more, depending on the length of the runs and the number of access points, and the area is cleaned down before we leave. Somewhere like Westwick Row, lanes, gates and parking are worth mentioning in advance.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down

Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Then call 0345 646 2711, or email photos.

What happens if it’s left?
Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. Anywhere that reaches 500 microns or more needs immediate spot cleaning. Putting off the clean only pushes readings higher. Our emergency line runs 24/7, but a planned visit to Westwick Row is calmer for everyone.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.

What the work involves, part by part
Attenuators and discharge
Attenuators, where fitted, quieten the extract, but they can hold grease in their linings. They’re cleaned where possible and recorded if not.
Horizontal duct runs
Long horizontal runs need access panels at regular intervals. Any stretch out of reach is noted and can fit extra panels.
