About our ductwork cleaning in Denmark Hill
Every duct has its own route. Some run a short distance to an outside wall, others climb several floors to the roof. We map the route during the survey and finds every access point before we quote. Common call-outs are for grease pooling at the foot of the riser and ductwork that has never been cleaned, across vertical risers, bends and junctions and attenuators.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Denmark Hill, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
The report is your 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.

Honest limits
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- Undersized or badly laid-out ducts
- A damper stuck open in the duct
If in doubt, phone us on 0345 646 2711, or email photos and we’ll say what we think.

Grease, kitchens and Denmark Hill
There are about 520 restaurants, cafés and works canteens and about 295 takeaways and sandwich shops within about 1.5 miles of central Denmark Hill, according to the Food Standards Agency’s register. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. Most London extract cleaning happens at night, after the last service. It’s Southwark council that sends environmental health officers to food businesses in Denmark Hill. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
Bursars and site managers at schools such as Lyndhurst Primary School tend to book extract cleaning for when the kitchen is empty. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Denmark Hill is St Giles' Hospital, about 0.6 miles north-east. Where a hall near St Matthew's Camberwell, or anywhere in Denmark Hill, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Aftercare tips
So the system stays in good health:
- Leave a way through to the access panels
- Keep to the interval on the report
- Flag drips from the duct straight away
- Get panels fitted where the duct couldn’t be cleaned
After the clean, the same points are tested again, so the report shows the before and after figures. Photos of each section go alongside them.
Watch for warning signs between cleans: drips from the ductwork, stale smells or a noisy fan. A grease thickness test can confirm whether a spot clean is needed.

What staff can safely do
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.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
How we price ductwork cleaning
The diagnosis comes before the price. The main factors are:
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
- Where the site is and how we reach it
- The scale of the work
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
Asking for a quote
You don’t need the technical terms. It helps if you can send:
- Any previous report or certificate
- Any access panels or hatches you can see
- Wide pictures of the system and the area around it
- Your opening hours and when the area is out of use
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Then call us on 0345 646 2711 or use the quote form.
Part by part
Attenuators and discharge
At the end of the duct is the discharge. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
Vertical risers
Risers often pass through floors and walls, so fire dampers may be fitted where it crosses them. We test those as a separate job.
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes a few hours for a short run, longer for long runs and tall risers. In a London area like Denmark Hill, parking, loading and building access are planned before the day of the work.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- Bends, risers and the base of each riser get extra attention.
- Readings, photos and a recommended next clean date complete the job.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Tell us where we can park and unload
- Let us know about permits to work or site inductions

Denmark Hill: your questions answered
Can parking be tricky for a job in Denmark Hill?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we’ll book into it.
Do you do school kitchen extract cleaning in Denmark Hill in the summer holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 85 schools and colleges with food registrations within roughly a mile and a half of Denmark Hill. Send us your term dates when you phone us on 0345 646 2711, or send details by email, and we’ll fit the work in.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
How often does extract ductwork need cleaning?
At least as often as BESA guidance sets for your cooking hours. Heavy use of 12 to 16 hours a day means at least every 3 months, while lighter use can go longer.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What’s involved in cleaning extract ducts?
We open each access panel and clean the section it reaches. Grease is scraped out first, then degreased, with readings taken before and after.
Managing agents and facilities teams in Denmark Hill
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’re happy to quote for all of it.
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 pictures.
