Ductwork cleaning for kitchens and businesses in St Helens
Every duct has its own route. A few metres to an outside wall, or a riser up through the building to a roof fan. We map the route during the survey, so we know where to get in and how long it will take. We are often asked to deal with stale grease odours from the duct and grease leaking from duct joints, on horizontal duct runs, vertical risers and bends and junctions.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Ductwork cleaning around St Helens
St Helens lies within about 2 miles of the sea. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. Food Standards Agency data counts about 19 restaurants, cafés and canteens within roughly a mile and a half of the centre of St Helens. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. St Helens is covered by Hampshire and Isle of Wight Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Church and community hall kitchens, near St Catherine-by-the-Green or anywhere around St Helens, are easy to forget, but their extracts collect grease like any other. If you run catering at a historic house or estate in the area (Yaverland Manor is about 2.1 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning.

Leave it or put it right?
Old grease in a duct for a kitchen in St Helens doesn’t stay soft. It bakes into a hard layer that takes far longer to remove, which makes each delayed clean a bigger one. It’s worth booking a check, because nobody sees inside a duct day to day.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before work begins.

How the job changes from site to site
Vertical risers
Cleaning a riser needs access along its height. Any part that cannot be safely reached is recorded.
Horizontal duct runs
Long horizontal runs need access panels at regular intervals. Any stretch out of reach is noted and can fit extra panels.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
What we do, step by step
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. The work itself takes from a few hours to more than one visit, depending on duct length and access. For a village or hamlet like St Helens, tell us about narrow lanes, gates and parking when you book.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Out of hours, the area is protected and the access panels opened.
- Heavy deposits come out by hand, then each section is degreased.
- We close up, re-test, photograph and record anything out of reach.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in

Questions from St Helens
Who is the fire and rescue service for St Helens?
Hampshire and Isle of Wight Fire and Rescue Service is the fire and rescue service for St Helens. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you do school kitchen extract cleaning in St Helens in the summer holidays?
Yes, and it’s the easiest time to do it. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of St Helens, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
How long does it take to clean extract ducts?
Duct length, access and grease levels all affect it. As a guide, it takes from a few hours to more than one visit, depending on duct length and access.
What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
How do you clean inside the ductwork?
After a survey and grease readings, the duct is opened up through its access panels. Each run and riser is scraped and degreased, then the readings are repeated.
What’s the cleaning interval for extract ductwork?
At least as often as BESA guidance sets for your cooking hours. Kitchens cooking 12 to 16 hours a day need it at least every 3 months, while lighter use can go longer.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Ask for a grease thickness test if the kitchen gets busier
- Consider fitting panels where the report shows gaps
- Tell us if grease leaks from the ductwork
- Leave a way through to the access panels
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
Extra access panels mean more of the duct gets cleaned each time. Grease you can reach is grease that gets removed.
Signs you need ductwork cleaning in St Helens
Damaged or poorly fitted filters let more grease into the duct. The duct then takes grease that the filters should have stopped and it fills faster.
Clients usually contact us when they notice something like this:
- Smells of old cooking grease from the ductwork
- An insurer asking for TR19 evidence
- A grease test showing the duct is overdue
- Years of grease along the duct floor
If you look after a school kitchen, at a school such as St Helens Primary School or anywhere near St Helens, the holidays are the usual time for a TR19® clean.
