Common problems we fix in Sydenham
Many ducts do not have enough access panels. Sections between panels go uncleaned, sometimes since the system was installed, and the grease there keeps building out of sight.
Look out for these warning signs:
- Stale grease odours from the duct
- Years of grease along the duct floor
- An insurer asking for TR19 evidence
- Duct runs with no cleaning record
A hospital like St Christopher's Hospice, about less than half a mile south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Questions to ask before you book
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether a survey comes first
- Proof of insurance
- Whether the figure could change on the day
Ductwork cleaning in Sydenham
Many ducts were installed with too few access doors. TR19 calls for any section we couldn’t reach to be recorded, and new panels can be fitted to reach it in future. It’s better to know than to assume. Common call-outs are for high readings at a recent grease test and a duct clean needed for an insurer, on attenuators, access panels and multi-storey ducts.
In a London area like Sydenham, 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, which is why keeping it clean to TR19® matters.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Your questions about ductwork cleaning in Sydenham
Who inspects food businesses in Sydenham?
Food hygiene inspections in Sydenham are carried out by Lewisham council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
What do you need to know about parking in Sydenham?
A loading bay, a visitor permit or off-street space near the site in Sydenham makes the visit easier to plan. Night visits tend to make loading easier on London streets.
Do you survey before quoting?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
How do you protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
Will I get a report after the ducts are cleaned?
Readings, photos and, for a full clean, a TR19 certificate. It also gives a recommended next clean date.
How often does extract ductwork need cleaning?
The minimum depends on how long the kitchen cooks each day: 3-monthly for heavy use, 6-monthly for moderate and 12-monthly for light use. Grease readings may show it needs doing sooner.
What a clean will not put right
Before you book, it helps to know what’s not included:
- An extract fan that has stopped working
- Leaking duct joints that need repair
- A duct that’s too small or badly routed for the kitchen (a design issue)
If in doubt, call us on 0345 646 2711 or use the quote form and we will say what we think before you book.

Ductwork cleaning around Sydenham
There are about 259 restaurants, cafés and works canteens and about 141 takeaways and sandwich shops across Sydenham and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. Kitchens in Sydenham get their food hygiene inspections from Lewisham council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
For schools such as Kirkdale School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Volunteers running a hall kitchen near Church of St Bartholomew, or anywhere in Sydenham, may not know when the extract was last cleaned, and a grease test settles it.

Fixed quotes for ductwork cleaning in Sydenham
The diagnosis comes before the price. We look at:
- How easy every part is to reach
- One-off work versus a regular cycle
- When the work can happen, such as evenings, overnight or weekends
- The condition we find in the survey
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
Helping us quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Multi-site and managed buildings
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
The process
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes from a few hours to more than one visit, depending on duct length and access, and the area is cleaned down before we leave. Most London sites cannot stop for the day, so work in Sydenham is typically done overnight, early in the morning or at weekends.
- 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.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
How to prepare
- Mention any parking or loading restrictions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool
Getting a quote
To get a fixed quote, phone us on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You will typically have a quote within one working day.

Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Don’t switch the extract off early
- Don’t block access panels with shelving or stock
- Ask for a grease thickness test if the kitchen gets busier
- Store the certificate with the fire risk assessment
The report gives a recommended next clean date, based on the readings and your daily cooking hours, in line with BESA guidance.
Book the next duct clean before the date passes. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
