Signs you need ductwork cleaning in Lewisham
Wherever the kitchen is, in Lewisham or elsewhere, the duct fills in the same way: hours of cooking, the type of food and how well the filters are kept. BESA guidance sets minimum intervals of 3, 6 or 12 months depending on daily use.
Common reasons sites call us include:
- Grease leaking from duct joints
- Ductwork that has never been cleaned
- High readings at a recent grease test
- Stale grease odours from the duct
If you run catering at a healthcare site, such as a hospital like University Hospital Lewisham about 0.6 miles south-west, the extract may need cleaning more often than a part-time kitchen.

Ductwork cleaning in Lewisham
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it, and that’s where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. The work covers multi-storey ducts, vertical risers and attenuators, and people most often call us about years of grease along the duct floor and stale grease odours from the duct.
In a London area like Lewisham, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What the work involves, part by part
Access panels
Panels have to seal properly once they’re closed so the duct stays tight. We’ll tell you if any panel needs replacing.
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.
What ductwork cleaning can’t fix
In fairness, there are a few things this work won’t fix:
- A duct that is too small or badly routed for the kitchen (a design issue)
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- Faulty fire dampers
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we will tell you honestly.

Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
Why act early in Lewisham
Booking the duct clean in Lewisham now keeps it a planned job. The work takes a shift or more, depending on the length of the runs and the number of access points, done out of hours so the kitchen keeps cooking. For a site in Lewisham, fitting the work in overnight now is far easier than closing at short notice later.
What you pay depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

Lewisham: your questions answered
Can a school canteen extract in Lewisham be done out of term time?
Yes, holiday work suits schools best. Food Standards Agency records list about 48 schools, colleges and universities with registered kitchens within about a mile and a half of Lewisham. You can ring 0345 646 2711 or email us with the dates the site is empty.
How do you handle parking and loading in Lewisham?
Tell us where a van can stop near your site in Lewisham, and about any building rules on loading. Working overnight, as we often do in London, normally makes it simpler.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
How long does ductwork cleaning take?
Duct length, access and grease levels all affect it. As a guide, it takes a few hours for a short run, longer for long runs and tall risers.
Do you install duct access panels?
Yes, we do. We’ll point out where panels are needed, and fitting them means future cleans are more complete.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes anything from a few hours to several visits, depending on the length of duct. If your building in Lewisham has sign-in rules, permits or key holders, mention them when you book.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Heavy deposits come out by hand, then each section is degreased.
- We close up, re-test, photograph and record anything out of reach.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Mention any sign-in, permit or induction we need
- Clear the space around the work
How to get a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, phone us on 0345 646 2711 or email us.
Advice
Grease, kitchens and Lewisham
The FSA’s food hygiene register includes about 63 bars, pubs and nightclubs and about 11 hotels, B&Bs and guest houses within about 1.5 miles of central Lewisham. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Lewisham is covered by London Fire Brigade. 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. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
If you run a café or takeaway near Lewisham station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Church and community hall kitchens, near St Stephen's Church or anywhere around Lewisham, are easy to forget, but their extracts collect grease like any other.

In-house cleaning or a specialist?
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
