Crooked Billet ductwork cleaning
Cleaning of kitchen extract ductwork, horizontal runs and vertical risers through access panels for Crooked Billet, with a survey first and a report with photos at the end. Ask us for a fixed quote.
- Heavy grease at the base of a riser
- Readings above 200 microns from a grease thickness test
- Thick crusts of old grease along the duct
Why act early in Crooked Billet
Grease narrows the duct and slows the air. Less air moves, so heat and smoke stay in the kitchen while the fan strains and grease can drip from duct joints. A busy site in Crooked Billet builds up dirt and wear quickly, so putting it off makes the eventual job larger.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
Why us?
- A fixed price before any work starts
- A written report with photos after each visit
- A single point of contact for sites across the South East and London
- CHAS and SafeContractor accredited, with ISO 9001

Ductwork cleaning for kitchens and businesses in Crooked Billet
Ductwork in Crooked Billet is cleaned the same thorough way as everywhere else we work: readings at set points, heavy grease scraped out by hand, then degreasing to suit the deposit. Post-clean readings and pictures complete the record. The work covers vertical risers, horizontal duct runs and bends and junctions, and common reasons people get in touch are duct runs with no cleaning record and years of grease along the duct floor.
Kitchens in Crooked Billet, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What else we do in Crooked Billet
Kitchen extracts in Crooked Billet
Food Standards Agency records list about 208 cafés, restaurants and staff canteens and about 32 sandwich bars and takeaways in Crooked Billet and the streets around it, up to about 1.5 miles out. Behind every canopy among them is a run of ductwork that collects grease out of sight. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Environmental health officers from Merton council inspect food businesses in Crooked Billet. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
Volunteers running a hall kitchen near Christ Church, or anywhere in Crooked Billet, may not know when the extract was last cleaned, and a grease test settles it. School kitchens, at schools like Wimbledon College for example, are typically cleaned in the holidays so no lunches are lost.

What a clean won’t put right
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
- A worn-out fan that needs replacing
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we will tell you honestly before you book.
Where we work
- Horizontal duct runs
- Multi-storey ducts
- Bends and junctions
- Access panels
- Vertical risers
- Attenuators
Signs you need ductwork cleaning in Crooked Billet
A duct with too few access doors can’t be fully cleaned. Sections between panels go uncleaned, sometimes since the system was installed, and grease there keeps thickening unseen.
The symptoms we’re asked about most include:
- A duct nobody has opened in years
- A duct clean needed for an insurer
- A rancid smell from the extract duct
- Grease seeping out of the duct seams
If you run a café or takeaway near Raynes Park station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
What your quote should include
- What’s included in the scope, part by part
- Proof of accreditation you can verify
- Whether the quote is based on a survey or photos
- Whether the work can be done while the site is closed
What staff can safely do
Staff cleaning and specialist work are not the same thing. 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.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
How the job changes from site to site
Vertical risers
Risers are cleaned through panels at different levels. Any part that can’t be safely reached is recorded.
Access panels
After cleaning, every panel is closed and sealed so the duct stays tight. We’ll tell you if any panel needs replacing.
Aftercare tips
After the visit, a few habits help the work last:
- Run the extract fan throughout service
- Have the grease measured if cooking hours go up
- Never cook with a filter missing
- Get panels fitted where the duct couldn’t be cleaned
Keep the certificate and report with the fire risk assessment. An insurer, fire officer or EHO may ask to see it, and the pictures make the duct’s condition easy to see.
The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.
How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes a shift or more, depending on the length of the runs and the number of access points, and we clear up before we go. If your building in Crooked Billet has sign-in rules, permits or key holders, mention them when you book.
- 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, photos and a recommended next clean date complete the job.
Preparing for the visit
- Have your last certificate or report to hand
- Allow time for equipment near the work to be turned off and cool down
- Tell us where we can park and unload
Ask for a quote
Getting a quote doesn’t take long. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Common questions in Crooked Billet
Which environmental health team covers Crooked Billet?
In Crooked Billet, it’s Merton council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
What do you need to know about parking in Crooked Billet?
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.
How is kitchen extract ductwork cleaned?
We get into the duct through its access panels. Heavy grease is scraped out by hand, then the surfaces are degreased with a method that suits the deposit, such as degreasers, hot water or steam.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
Do you install duct access panels?
Yes, extra panels can be fitted. That lets the next clean reach sections that were missed, and the report will show where they’re needed.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
What happens if you cannot reach some of it?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
