How we price ductwork cleaning
We don’t publish a price list, because no two systems are the same. What we look at:
- Parking and loading at the site
- The scale of the work
- When the work can happen, such as evenings, overnight or weekends
- How easy every part is to reach
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.
What we need to know
What to send for a quote:
- Photos showing the whole system and its surroundings
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
To get a fixed quote, phone us on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We typically come back within one working day.
Ductwork cleaning in Rowley Green, done properly
Duct Doctor has cleaned kitchen extract ductwork 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, and our certificates are issued through the BESCA Vent Hygiene Elite portal. The work covers horizontal duct runs, multi-storey ducts and attenuators, and the jobs we see most are high readings at a recent grease test and hardened, baked-on grease in long horizontal runs.
London kitchens tend to trade late and open early, so extract cleaning in Rowley Green is normally done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

FAQs for Rowley Green
What do you need to know about parking in Rowley Green?
A loading bay, a visitor permit or off-street space near the site in Rowley Green makes the visit easier to plan. Working overnight, as we often do in London, normally makes it simpler.
Can you work in Rowley Green outside opening hours?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
How do you protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Ring any time and tell us what’s happened.
Will we have to shut during the visit?
Usually not. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits so parts stay in use.
How long will the duct clean take?
Allow a few hours for a short run, longer for long runs and tall risers. We will confirm the time when we quote.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
How the job changes from site to site
Vertical risers
Risers often pass through floors and walls, where fire dampers may be fitted. Damper testing is a separate service.
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
Signs you need ductwork cleaning in Rowley Green
Slow air leaves the most grease behind. Flat runs, bends, reducers and the base of risers are the usual hotspots, and those are the points we pay most attention to.
It’s time to book a visit if you see:
- Stale grease odours from the duct
- Ductwork that has never been cleaned
- Years of grease along the duct floor
- Thick deposits at the bottom of a vertical duct
School kitchens, at schools like Saffron Green Primary School for example, are normally cleaned in the holidays so no lunches are lost.
Before you book anyone
- What insurance they carry
- What paperwork you get at the end
- Which accreditations they hold, and whether you can check them
- What’s included in the scope, part by part
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Make sure filters are seated properly
- Consider fitting panels where the report shows gaps
- Do not block access panels with shelving or stock
- Report any grease dripping from duct joints
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.
For landlords and multi-site operators
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
When it’s something else
Ductwork cleaning cannot fix everything, and we’ll tell you before we start. It doesn’t solve:
- Leaking duct joints that need repair
- A failed fan motor at the end of the duct (a fan repair job)
- A duct that’s too small or badly routed for the kitchen (a design issue)
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we’ll say what we think before booking.
Parts of the system we cover

Rowley Green kitchens: local notes
Food Standards Agency records include about 11 pubs, bars and clubs and about 4 hotels and B&Bs within 1.5 miles or so of the middle of Rowley Green. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. London Fire Brigade covers Rowley Green. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Environmental health officers from Barnet council inspect food businesses in Rowley Green. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
If you run catering at a historic house or estate in the area (Wyllyotts Manor is about 3.7 miles north-east), event kitchens in older buildings often have awkward duct runs that need planning. If you run a church or community hall kitchen, near Holy Cross or elsewhere in Rowley Green, its extract still collects grease from every lunch and event.

How the visit works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes anything from a few hours to several visits, depending on the length of duct. In Rowley Green, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- First the duct route is traced and every access point noted.
- Grease readings are taken at set points along the duct.
- We open the panels and scrape out the heaviest grease.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
Preparing for the visit
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
