Ductwork cleaning for kitchens and businesses in Colindale
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Grease settles along every metre of it and a fire in the duct can spread through the building. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. If you have heavy grease at the base of a riser and a duct nobody has opened in years, we can put it right.
Kitchens in Colindale, 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.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- A failed fan motor at the end of the duct (a fan repair job)
- Fire dampers that don’t close (they need testing and remedials)
If you’re not sure, just phone us on 0345 646 2711 or use the quote form and we will give you a straight answer.

How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. 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 the area is cleaned down before we leave. For a job in Colindale, tell us about loading bays, permits, lifts and roof access when you book.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- 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
- Mention any locked doors, roof access or ceiling voids
- Name a contact who can let us in at the agreed time
- Let us know about permits to work or site inductions

Advice
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Kitchen extracts in Colindale
According to Food Standards Agency records, there are about 22 pubs and bars within roughly a mile and a half of the centre of Colindale. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Night work suits London kitchens, and roads and loading bays tend to be quieter too. London Fire Brigade covers Colindale. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you look after a school kitchen, at a school such as Colindale Primary School or anywhere near Colindale, the holidays are the usual time for a TR19® clean. If you run a church or community hall kitchen, near St Matthias the Apostle church or elsewhere in Colindale, its extract still collects grease from every lunch and event.

When to call us in Colindale
Grease in a duct running from a kitchen in Colindale is as much a fire risk as in any building. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
Signs it’s time to call us include:
- Duct runs with no cleaning record
- Years of grease along the duct floor
- Duct runs that cannot be reached
- Proof of duct cleaning for the insurer
A hospital like Edgware Community Hospital, about 1.3 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Your questions about ductwork cleaning in Colindale
Which fire and rescue service is responsible for Colindale?
Colindale is in the area of London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can you work in Colindale outside opening hours?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Just call 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
What information do you need?
A short description and a few pictures plus the address and your hours. If we need more, we will ask.
Who is responsible for fire safety on the premises?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. If you are not sure, check your lease and fire risk assessment.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
How often should kitchen ducts be cleaned?
The minimum depends on how long the kitchen cooks each day: 3-monthly for heavy use, 6-monthly for moderate and 12-monthly for light use. Measured grease sets the real interval.
Managing agents and facilities teams in Colindale
We also work for facilities teams across offices, schools and healthcare across Greater London. Work can be phased by floor, building or site around the people who use them.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
What happens if it’s left?
Fire inside a duct is out of sight and out of reach. The duct can carry it to rooms, floors or roof spaces well away from the kitchen, so cleaning the duct is as important as cleaning the hood. A building in Colindale may have flats or offices above and alongside, and a fault in the system can affect them too.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before any work starts.

How the job changes from site to site
Access panels
Every section of duct is cleaned through an access panel. Where there are none, those sections cannot be cleaned and the report has to say so.
Bends and transitions
Bends, elbows and changes of size are where grease collects most. The air slows and drops its load, so these points get extra attention.
