What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what ductwork cleaning won’t do:
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
- A failed fan motor at the end of the duct (a fan repair job)
- A damper stuck open in the duct
If you’re not sure, just call us on 0345 646 2711 or send us an email and we’ll give you a straight answer before you book.

How we handle ductwork cleaning in Mitcham
Ductwork in Mitcham is cleaned the same thorough way as everywhere else we work: we test the grease first, remove thick deposits by hand and degrease what’s left. Post-clean readings and photos complete the record. If you have high readings at a recent grease test and thick crusts of old grease along the duct, we can put it right.
In a London area like Mitcham, 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.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

How we price ductwork cleaning
We quote each job individually. These are the things that affect it:
- How big the system is
- Site requirements such as sign-in and permits
- The times the site is available
- A single visit or a regular plan
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before any work starts.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Close-ups of filters, grilles, hatches or access panels
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
- Wide photos of the system and the area around it
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Then call us on 0345 646 2711 or drop us a line.
Grease, kitchens and Mitcham
The FSA’s data shows about 11 pubs, bars and clubs registered within 1.5 miles or so of the middle of Mitcham. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected. Mitcham is covered by London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Where a hall near St. Mark's Church, or anywhere in Mitcham, hosts lunch clubs or events, its extract gathers grease just as a café’s does. A hospital like Wilson Hospital, about 0.5 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Mitcham is about 2 miles west of Thornton Heath, in Greater London. Whatever kind of site you run in Mitcham, we can take on ductwork cleaning. We can work out of hours so trading isn’t interrupted. Mitcham is one of 764 towns, villages and districts in Greater London we cover for commercial clients. For sites nearby, see our London page, about 7 miles away.
We cover every part of the CR4, SW16 and SM4 postcode area for ductwork cleaning and the roads nearby. Streets in the area include Kings Road, Baker Lane and Manor Road, and we cover them all for ductwork cleaning. Close by, we work in Hackbridge (1 mile north), Eastfields (1 mile north), Colliers Wood (1 mile north-west), Merton Abbey (2 miles north-west) and Furzedown (2 miles north).

The closest station to Mitcham is Mitcham Eastfields station, roughly 0.5 miles north of the centre. Nearby you’ll also find Wandle Industrial Museum (0.7 miles west) and Centrale Croydon (2.7 miles south-east). The countryside around Mitcham includes Duppas Hill and Cranmer Green.
Between visits
Think of this as the after-treatment advice, short and simple:
- Tell us if grease leaks from the ductwork
- Get panels fitted where the duct couldn’t be cleaned
- Store the certificate with the fire risk assessment
- Book the next clean before the recommended date
Keep the certificate and report with the fire risk assessment. An insurer, fire officer or EHO may ask to see it, and the photos make the duct’s condition easy to see.
Some signs mean the duct needs attention sooner: grease leaking from duct joints, smells, or a fan that sounds rough. Testing will show whether any section has reached 500 microns.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

What else we do in Mitcham
What we do, step by step
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes a shift or more, depending on the length of the runs and the number of access points. Security desks and permits-to-work are routine in London, so let us know what your building in Mitcham needs from us.
- The duct route is surveyed and every access point found.
- 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.
- We close up, re-test, photograph and record anything out of reach.
Preparing for the visit
- Clear loose items from the work area
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms

Related advice
Signs you need ductwork cleaning in Mitcham
Slow air leaves the most grease behind. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
Keep an eye out for these warning signs:
- An insurer asking for TR19 evidence
- High readings at a recent grease test
- Ductwork that has never been cleaned
- Grease seeping out of the duct seams
A kitchen near Mitcham Eastfields station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Mitcham questions
Can school kitchens in Mitcham be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Mitcham, the Food Standards Agency lists about 30 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you ring 0345 646 2711, or send details by email, and we will fit the work in.
Who is the fire and rescue service for Mitcham?
It’s London Fire Brigade, which covers Mitcham. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
How do you clean inside the ductwork?
We open each access panel and clean the section it reaches. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.
Can you set up regular visits?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
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.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Why deal with it now?
There’s no law that names TR19. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, including the grease inside the extract ductwork. In Mitcham, a planned overnight visit is much easier than closing unexpectedly.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
