Ductwork cleaning in Rosehill, Greater London
Our technicians work in Rosehill on ductwork cleaning. Out-of-hours visits, a fixed quote and a written report with photos on every job.
- Grease leaking from duct joints
- Stale grease odours from the duct
- A grease test showing the duct is overdue
What we do, step by step
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a shift or more, depending on the length of the runs and the number of access points. Before any visit in Rosehill, we agree where the van can stop and how equipment reaches the system.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Getting ready for the visit
- Let us know about parking and loading
- Mention any locked doors, roof access or ceiling voids
- Let us know when the site is closed or quiet

Ductwork cleaning in Rosehill
No two duct runs are the same, in Rosehill or anywhere else. Some run a short distance to an outside wall, others climb several floors to the roof. We map the route during the survey, so we know where to get in and how long it will take. Typical jobs include a duct clean needed for an insurer and years of grease along the duct floor, on attenuators, vertical risers and bends and junctions.
In a London area like Rosehill, 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 photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What we are called out for in Rosehill
Grease filters that don’t seal let fat straight through. More grease reaches the ductwork than it should and it fills faster.
What we are most often called out for:
- A duct clean needed for an insurer
- High readings at a recent grease test
- Duct runs that can’t be reached
- Heavy grease at the base of a riser
A kitchen near Sutton Common station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
Questions to ask before booking
- Whether VAT is included
- How they set the interval to the next visit
- What insurance they carry
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
Different parts, different methods
Access panels
After cleaning, every panel is closed and sealed so the duct stays tight. A damaged panel is noted on the report.
Bends and transitions
A bend can hold far more grease than a straight run of the same length. It’s scraped out and degreased, and readings are taken there before and after.
What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

Questions from Rosehill
Do you work at weekends in Rosehill?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Who would carry out a food hygiene inspection at a kitchen in Rosehill?
That is Sutton council, whose environmental health officers carry out food hygiene inspections in Rosehill. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
Do we lose a day’s trading?
Not usually. The area we’re working in has to be out of use while we are there, so the visit goes in a quiet slot.
Does the law say we must follow TR19?
Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply give us a ring on 0345 646 2711, or email photos.
Fixed quotes for ductwork cleaning in Rosehill
A fixed price needs a few facts first. We check:
- The scale of the work
- Access, including roofs, risers and ceiling voids

What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
For a fixed quote, phone us on 0345 646 2711, or email photos 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. We normally come back within one working day.
Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Book the next clean before the recommended date
- Have the grease measured if cooking hours go up
- Leave a way through to the access panels
- Get panels fitted where the duct couldn’t be cleaned
Grease readings are taken again at the same set points, giving you before and after readings. Photos of each section go alongside them.
Some signs mean the duct needs attention sooner: drips from the ductwork, stale smells or a noisy fan. Testing will show whether any section has reached 500 microns.
Rosehill kitchens: local notes
The FSA’s food hygiene register shows about 164 cafés, restaurants and staff canteens and about 93 sandwich bars and takeaways in and around Rosehill, up to about a mile and a half out. The duct above a busy canopy coats itself in grease long before anyone sees it. London jobs usually start after the last service, with loading and roof access agreed with the building first. It’s Sutton council that sends environmental health officers to food businesses in Rosehill. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
If you look after a school kitchen, at a school such as Tweeddale Primary School or anywhere near Rosehill, the holidays are the usual time for a TR19® clean. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Rosehill is St Helier Hospital, about less than half a mile south.

When something else is needed
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- A duct that is too small or badly routed for the kitchen (a design issue)
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- An extract fan that has stopped working
If in doubt, give us a ring on 0345 646 2711, or email photos and we’ll say what we think before booking.
