What ductwork cleaning cannot fix
Not every problem is solved by ductwork cleaning, and we’d rather say so up front. It does not solve:
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
- Ductwork that was poorly designed
- Leaking duct joints that need repair

Ductwork cleaning for kitchens and businesses in Inner Avenue
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. We clean it from the inside, through access panels, to BESA TR19® Grease. We are often asked to deal with grease seeping out of the duct seams and a rancid smell from the extract duct, across access panels, attenuators and vertical risers.
Size does not change the work: a kitchen in a place like Inner Avenue gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Why deal with it now?
A dirty duct is something insurers ask about. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. Your certificate and photo report show the ducts were cleaned. A quieter site near Inner Avenue still needs its system looked after.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before any work starts.

Different parts, different methods
Access panels
Panels have to seal properly once they’re closed, so grease and air stay inside the duct. We will tell you if any panel needs replacing.
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, so the base is one of our test points.
How it works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes a shift or more, depending on the length of the runs and the number of access points. Around Inner Avenue, access is typically simpler than in a town centre, though gates and roof access are worth mentioning.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, photos and a next clean date.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
- Tell us about site rules, permits or sign-in

Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Tell us if grease leaks from the ductwork
- Ask for a grease thickness test if the kitchen gets busier
- Keep the fan on while anything is cooking
- Never cook with a filter missing
The report gives a recommended next clean date, based on the readings and your daily cooking hours, in line with BESA guidance.
Keep the fan on throughout service. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
Your questions about ductwork cleaning in Inner Avenue
Can you clean school kitchen extracts in Inner Avenue during the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 34 schools, colleges and universities with registered kitchens within about a mile and a half of Inner Avenue. You can call us on 0345 646 2711 or send us an email with the dates the site is empty.
Can sea air affect ductwork cleaning in Inner Avenue?
It can, as Inner Avenue is within about 2 miles of the sea, where salt in the air is hard on metal. A fan housing that’s rusting near the coast can fail sooner, so it’s worth catching early.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained to keep the area clean.
Do you install duct access panels?
Yes, we do. The survey or clean shows where sections couldn’t be reached, and we can fit them so those sections are cleaned in future.
Do I get a certificate for ductwork cleaning?
Readings, pictures and, for a full clean, a TR19 certificate. The report says when the next clean is due.
How can I tell if my extract ducts are dirty?
A grease thickness test gives the answer. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. A mean above 200 microns, or 500 microns at any point, means it’s due.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
Signs you need ductwork cleaning in Inner Avenue
The further the air travels from the cooking, the cooler it gets. Cooling air drops its grease onto the inside of the duct, so duct runs keep collecting grease long after the canopy.
These are the problems we see most often:
- Thick deposits at the bottom of a vertical duct
- Gaps where access panels were never fitted
- Proof of duct cleaning for the insurer
- A rancid smell from the extract duct
If you look after a school kitchen, at a school such as Bevois Town Primary School or anywhere near Inner Avenue, the holidays are the usual time for a TR19® clean.

Grease, kitchens and Inner Avenue
The coast is only about 2 miles from Inner Avenue. Salt air speeds up corrosion of roof-level fans, discharge cowls and their fixings. According to Food Standards Agency records, there are about 103 pubs and bars and about 25 hotels and B&Bs across Inner Avenue and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Hampshire and Isle of Wight Fire and Rescue Service covers Inner Avenue. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Healthcare kitchens, like those at hospitals such as Royal South Hants Hospital (about less than half a mile south-east), often cook for long hours, which puts them in BESA’s heavier-use bands. A kitchen near St Denys station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
