Different parts, different methods
Vertical risers
Cleaning a riser needs access along its height. Where it can’t be reached safely, the report says so.
Horizontal duct runs
Horizontal runs carry the extract along ceilings and through voids. They collect grease as the air cools and slows, so each section is cleaned through its access panels.
Ductwork cleaning for kitchens and businesses in Downe
In doctor’s terms, the ductwork is the system’s arteries: diagnose where grease has built up, clear it and confirm the result. Readings taken before and after show the difference, alongside before and after photos. If you’re dealing with sections of duct with no access panels and a rancid smell from the extract duct, we can help, from vertical risers, multi-storey ducts and horizontal duct runs onwards.
In London, few kitchens can spare a day to close, so work in Downe is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Managing agents and facilities teams in Downe
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.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Why deal with it now?
Grease left in a duct in Downe hardens over time. Heat and age turn it into a thick, stubborn crust, so the later the clean, the bigger the job. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

How it works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Downe.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access panel.
- We take extra care at bends and at the foot of risers.
- Readings, pictures and a recommended next clean date complete the job.
Before we arrive
- Let us know about permits to work or site inductions
- Name a contact who can let us in at the agreed time
- Dig out any earlier paperwork for the system
Getting a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, ring 0345 646 2711 or use the quote form.

What else we do in Downe
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Never cook with a filter missing
- Keep to the interval on the report
- File each certificate and photo report in the maintenance log
- Flag drips from the duct right away
The report gives a recommended next clean date, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Run the extract the whole time the kitchen is cooking. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
FAQs for Downe
What do you need to know about parking in Downe?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Who inspects food businesses in Downe?
That is Bromley council, whose environmental health officers carry out food hygiene inspections in Downe. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
What happens if there are not enough access panels?
Any section we can’t reach is recorded on the report, as TR19 expects. New panels can be fitted to reach them in future.
What does ductwork cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we will typically reply within one working day.
What paperwork do you give after a duct clean?
Every clean comes with a photo report, plus a TR19 certificate when the whole system is cleaned. File them with the fire risk assessment.
How is kitchen extract ductwork cleaned?
Each section is cleaned through its own panel. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.
Downe kitchens: local notes
The Food Standards Agency lists about 4 pubs, bars and clubs as registered food businesses within roughly a mile and a half of the centre of Downe. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Environmental health officers from Bromley council inspect food businesses in Downe. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
Church and community hall kitchens, near St Mary's Church or anywhere around Downe, are easy to forget, but their extracts collect grease like any other. Down House, about 0.6 miles south, is one of the historic houses near Downe; if you run event catering at a venue like that, cleans can be booked between functions. A hospital like Princess Royal University Hospital, about 1.8 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Downe is about 4 miles south-west of Orpington, in Greater London.

What affects the cost of ductwork cleaning
Sites vary more than people expect. The main factors:
- How big the system is
- Working hours and out-of-hours timing
- A single visit or a regular plan
- How easy every part is to reach
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before any work starts.
Asking for a quote
We can often survey from photos. Try to include:
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
- When the site is open and when it’s quiet
To get a fixed quote, call 0345 646 2711 or email us 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 usually come back within one working day.
What a clean will not put right
Before you book, it helps to know what’s not included:
- Duct sections that need replacing
- Faulty fire dampers
- Duct sealed behind fixed ceilings or walls
If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think.
