Ductwork cleaning for kitchens and businesses in Norwood Green
No two duct runs are the same, in Norwood Green or anywhere else. A few metres to an outside wall, or a riser up through the building to a roof fan. The survey traces the route, so we know where to get in and how long it will take. The work covers bends and junctions, vertical risers and multi-storey ducts, and people most often call us about thick deposits at the bottom of a vertical duct and sections of duct with no access panels.
London kitchens tend to trade late and open early, so work in Norwood Green is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

When it’s something else
In fairness, there are a few things this work won’t fix:
- A worn-out fan that needs replacing
- A duct that’s too small or badly routed for the kitchen (a design issue)
- Fire dampers that don’t close (they need testing and remedials)
If you are not sure, just call us on 0345 646 2711, or email photos and we will give you a straight answer.

How we price ductwork cleaning
The quote reflects the site in front of us. We take into account:
- The condition of the system
- Whether we need access equipment or extra panels
- Whether it’s a one-off visit or part of a schedule
- The times the site is available
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
What we need to know
We can often survey from pictures. Try to include:
- Problems your staff have spotted
- Your opening hours and when the area is out of use
- Any access panels or hatches you can see
- Photos showing the whole system and its surroundings
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Common problems we fix in Norwood Green
Wherever the kitchen is, in Norwood Green or elsewhere, the duct fills in the same way: daily cooking hours, the menu and the state of the filters. Under BESA guidance, the minimum interval is 3, 6 or 12 months, by daily cooking hours.
Look out for these warning signs:
- A duct nobody has opened in years
- Duct runs that can’t be reached
- A duct clean needed for an insurer
- Stale grease odours from the duct
Historic houses near Norwood Green, such as Osterley House about 0.6 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Norwood Green questions
Which environmental health team covers Norwood Green?
The local authority for Norwood Green is Ealing council, and its environmental health team does the inspecting. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Which fire and rescue service is responsible for Norwood Green?
It’s London Fire Brigade, which covers Norwood Green. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can extra access doors be added to the duct?
Yes, we install duct access panels. Panels go where they give the best access to sections that couldn’t be reached, and we will recommend where.
How long will the duct clean take?
It takes from a few hours to more than one visit, depending on duct length and access. The survey tells us how long your duct needs.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
What information do you need?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
What if parts of the system cannot be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
Ductwork cleaning in Norwood Green: the local picture
Food Standards Agency records list about 221 cafés, restaurants and staff canteens and about 101 sandwich bars and takeaways within 1.5 miles or so of the middle of Norwood Green. The duct above a busy canopy coats itself in grease long before anyone sees it. Norwood Green 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. Environmental health officers from Ealing council inspect food businesses in Norwood Green. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Bursars and site managers at schools such as St Mary's Church of England Primary Norwood Green tend to book extract cleaning for when the kitchen is empty. If you run catering at a healthcare site, such as a hospital like St Bernard's Hospital about 1 mile north-east, the extract may need cleaning more often than a part-time kitchen.

Aftercare tips
To keep the system working properly between visits:
- Keep the fan on while anything is cooking
- Do not block access panels with shelving or stock
- Tell us if grease leaks from the ductwork
- Make sure filters are seated properly
Grease readings are taken again at the same set points, so the report shows the before and after figures. Photos of each section go alongside them.
Have access panels fitted where sections cannot be reached. It doesn’t stop grease forming, but it stops it building unseen.
How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a shift or more, depending on the length of the runs and the number of access points. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Norwood Green.
- We start by working out how the duct runs and where it can be opened.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- We test again, take photos and note any part that couldn’t be reached.
How to prepare
- Tell us about site rules, permits or sign-in
- Have your last certificate or report to hand
- Tell us the best time to work, such as after service or at a weekend

Advice
Why it’s worth doing now in Norwood Green
Grease narrows the duct and slows the air. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy and grease can drip from duct joints. London sites work long hours, and the longer a job is left, the bigger it gets.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.

Facilities teams in offices, schools and healthcare sites book us too in Norwood Green and across Greater London. Work can be phased by floor, building or site to keep disruption down.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
