How we handle ductwork cleaning in Coulsdon
In doctor’s terms, the ductwork is the system’s arteries: find the blockages, clear them, then check the flow is right. Readings taken before and after show the difference, alongside before and after pictures. Typical jobs include grease pooling at the foot of the riser and ductwork that has never been cleaned, across vertical risers, horizontal duct runs and multi-storey ducts.
Kitchens in Coulsdon, 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.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Different parts, different methods
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.
Vertical risers
Risers carry the extract up through the building to the roof. Grease collects on the walls and at the foot of the riser, which is one of the points we test.
Honest limits
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- Faulty fire dampers
- A duct that is too small or badly routed for the kitchen (a design issue)
- Parts of the duct with no way in
Not sure which it is? You can phone us on 0345 646 2711 or email us and we’ll tell you honestly.

FAQs for Coulsdon
How do you handle parking and loading in Coulsdon?
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.
Who enforces fire safety at workplaces in Coulsdon?
Fire safety enforcement in Coulsdon is handled by London Fire Brigade. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you work in Coulsdon?
Yes. Our area takes in London and the counties of South East England, Coulsdon included.
How long does ductwork cleaning take?
Short runs are quick, but long or complex ducts may take several visits. We plan the work around your kitchen.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Do I get a certificate for ductwork cleaning?
When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. The report shows readings, pictures and any sections we couldn’t reach.
What do you need from me for a quote?
Just the basics: 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.
Why deal with it now?
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. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.

What we are called out for in Coulsdon
A duct with too few access doors cannot be fully cleaned. Stretches with no way in may never have been touched, and the grease there keeps building out of sight.
Keep an eye out for these warning signs:
- Readings above 200 microns from a grease thickness test
- Duct runs with no cleaning record
- Stale grease odours from the duct
- An insurer asking for TR19 evidence
If you run catering at a healthcare site, such as a hospital like Purley War Memorial Hospital about 2 miles north-east, the extract may need cleaning more often than a part-time kitchen.
Questions to ask before booking
- Whether the quote shows VAT
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What hours they’ll be on site
- Whether inaccessible sections are listed on the report
Ductwork cleaning in Coulsdon: the local picture
According to Food Standards Agency records, there are about 10 bars, pubs and nightclubs in Coulsdon and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Coulsdon is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
For schools such as Smitham Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. Commuter trade near Coulsdon South station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
What we do, step by step
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes anything from a few hours to several visits, depending on the length of duct. Loading bays, visitor permits and roof access are the first things we ask about for a site in Coulsdon.
- First we diagnose: the route, the access and the grease levels.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, pictures and a recommended next clean date complete the job.
How to prepare
- Clear loose items from the work area
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
We don’t publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, ring 0345 646 2711, or email photos.

Keeping the system healthy
Once we’ve finished, these simple steps help:
- Book the next clean before the recommended date
- Keep access panels clear of stored items
- Keep grease filters clean and fitted whenever you cook
- Tell us if grease leaks from the ductwork
The report gives a recommended next clean date, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Extra access panels mean more of the duct gets cleaned each time. Grease you can reach is grease that gets removed.
