About our ductwork cleaning in Seven Sisters
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it and a fire in the duct can spread through the building. We clean it from the inside, through access panels, to BESA TR19® Grease. If you’re dealing with grease pooling at the foot of the riser and stale grease odours from the duct, we can put it right, from attenuators, bends and junctions and multi-storey ducts onwards.
In London, few kitchens can spare a day to close, so extract cleaning in Seven Sisters is normally done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
What happens on the day
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes from a few hours to more than one visit, depending on duct length and access. A name and number for whoever controls access to the building in Seven Sisters saves time on the night.
- First we diagnose: the route, the access and the grease levels.
- 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.
- The duct is signed off with readings, pictures and a next clean date.
Preparing for the visit
- Let us know when the site is closed or quiet
- Mention any sign-in, permit or induction we need
- Mention any parking or loading restrictions
Get a fixed quote
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.

What affects the quote in Seven Sisters
The diagnosis comes before the price. We look at:
- Where the site is and how we reach it
- Site requirements such as sign-in and permits
- What state the system is in
- Whether it’s a one-off visit or part of a schedule
What you pay depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
What we need to know
Photos let us diagnose from a distance. Try to include:
- Any previous report or certificate
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The times we could work without disrupting the site
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Honest limits
To be straight with you, some problems need a different fix:
- Undersized or badly laid-out ducts
- Duct sealed behind fixed ceilings or walls
- Faulty fire dampers
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we’ll tell you honestly before you book.

What else we do in Seven Sisters
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Consider fitting panels where the report shows gaps
- Keep grease filters clean and fitted whenever you cook
- File each certificate and photo report in the maintenance log
- Run the extract fan throughout service
Every panel we open is refitted when we finish, and the surrounding area is left clean. Grease and dirty water are contained and removed.
Book the next duct clean before the date passes. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
When to call us in Seven Sisters
Many ducts do not have enough access panels. Stretches with no way in may never have been touched, and the grease there keeps building out of sight.
It’s time to book a visit if you see:
- A duct clean needed for an insurer
- A grease test showing the duct is overdue
- Stale grease odours from the duct
- Hardened, baked-on grease in long horizontal runs
For schools such as Earlsmead Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
Before you book anyone
- Whether the figure could change on the day
- Whether they’re fully insured
- How VAT is shown on the quote
- When the next visit should be, and why
Questions from Seven Sisters
Can you come to Seven Sisters after we close?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Seven Sisters needn’t be disturbed. Your opening times are the first thing we ask for.
Which fire and rescue service is responsible for Seven Sisters?
It’s London Fire Brigade, which covers Seven Sisters. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do we need to close while you work?
Not usually. We need the work area to ourselves while we’re on site, so the visit goes in a quiet slot.
Who has the legal duty for fire safety?
That depends on who controls the premises. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
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.
Can you price the work without visiting?
Usually, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we normally come back within one working day. If photos aren’t enough, we’ll survey first.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then call us on 0345 646 2711 or drop us a line.
Where does the waste go?
We take it away when we go. During the work, it’s contained so the area stays clean.

Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. Kitchens in Seven Sisters get their food hygiene inspections from Haringey council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
