Hampshire · Ductwork cleaning
Ductwork cleaning in South Wonston, Hampshire
Our technicians work in South Wonston on cleaning of kitchen extract ductwork, horizontal runs and vertical risers through access panels. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- Thick deposits at the bottom of a vertical duct
- Grease seeping out of the duct seams
- A grease test showing the duct is overdue
Multi-site and managed buildings
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Ductwork cleaning in South Wonston, done properly
Grease in a duct is hidden, which is exactly why it’s dangerous. Flames pulled in from the cooking line can ignite it, carrying a fire along the duct and into rooms far from the kitchen. Removing it is the whole point. The work covers multi-storey ducts, attenuators and bends and junctions, and the jobs we see most are a duct nobody has opened in years and grease pooling at the foot of the riser.
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. Access, parking and timings are agreed before the day.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How we price ductwork cleaning
The price is fixed before any work begins. It’s based on:
- Site requirements such as sign-in and permits
- Where the site is and how we reach it
- A single visit or a regular plan
- Access, including roofs, risers and ceiling voids
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any previous report or certificate
- Your opening hours and when the area is out of use
- Wide pictures of the system and the area around it

What staff can safely do
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
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 can diagnose it and quote.
Signs you need ductwork cleaning in South Wonston
Ducts in South Wonston gather grease for the same reasons as ducts anywhere: hours of cooking, the type of food and how well the filters are kept. BESA guidance sets minimum intervals of 3, 6 or 12 months depending on daily use.
Clients typically contact us after spotting one of these:
- Thick crusts of old grease along the duct
- A duct clean needed for an insurer
- Heavy grease at the base of a riser
- Sections of duct with no access panels
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to South Wonston is Royal Hampshire County Hospital, about 4 miles south.
What your quote should include
- Whether the work can be done while the site is closed
- If they look at the system before pricing
- What records you will receive afterwards
- Whether the figure could change on the day
Questions from South Wonston
Who inspects food businesses in South Wonston?
Kitchens in South Wonston are inspected by Winchester City council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can a school canteen extract in South Wonston be done out of term time?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of South Wonston. Just give us a ring on 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
Which accreditations do you hold?
Duct Doctor is 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.
How can I tell if my extract ducts are dirty?
The date on the last certificate is the first thing to check. If it’s overdue, or there isn’t one, a clean is due, and grease readings will confirm how urgent it is.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Can you quote from pictures?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Ask for a grease thickness test if the kitchen gets busier
- File each certificate and photo report in the maintenance log
- Do not switch the extract off early
- Never cook with a filter missing
Every panel we open is refitted when we finish, and the area around them is cleaned down. Waste grease and water are taken away.
The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.
When it’s something else
A few issues sit outside what this work can do:
- Ductwork that was poorly designed
- Fire dampers that do not close (they need testing and remedials)
- Leaking duct joints that need repair
Not sure which it is? You can call 0345 646 2711 or use the quote form and we’ll tell you honestly.

- Bends and junctions
- Vertical risers
- Access panels
- Horizontal duct runs
- Attenuators

What we do, step by step
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a few hours for a short run, longer for long runs and tall risers. Visits to a village like South Wonston are booked in advance, at a time that suits whoever runs the site.
- We map the duct route and check where the access panels are.
- 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.
- Post-clean readings and photos go into the report, with any unreachable section listed.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms
