Ductwork cleaning in Thornhill, Southampton
Ductwork cleaning for commercial sites in Thornhill and across Southampton. CHAS, SafeContractor and ISO 9001, and fully insured.
- A duct clean needed for an insurer
- Smells of old cooking grease from the ductwork
- Thick crusts of old grease along the duct
Why it’s worth doing now in Thornhill
BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. Anywhere that reaches 500 microns or more needs immediate spot cleaning. Leaving the duct makes those limits harder to keep to. Light use slows the build-up but doesn’t stop it.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before any work starts.

Ductwork cleaning in Thornhill, done properly
If the ducts in Thornhill haven’t been cleaned for a while, or nobody is sure when they were? A few details about the system are a good start when you ring 0345 646 2711 or use the quote form, and we will give you a fixed quote for ductwork cleaning, typically within one working day. Typical jobs include heavy grease at the base of a riser and duct runs with no cleaning record, on access panels, attenuators and multi-storey ducts.
Size doesn’t change the work: a kitchen in a place like Thornhill gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

How we price ductwork cleaning
A fixed price needs a few facts first. We check:
- How easy every part is to reach
- The number of sites or systems
- Any permits to work or inductions
- The scale of the work
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
What we need to know
What to send for a quote:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Grease, kitchens and Thornhill
At about 3 miles from the coast, Thornhill is close enough for sea air to matter. Salt air speeds up corrosion of roof-level fans, discharge cowls and their fixings. The Food Standards Agency lists about 18 pubs, bars and clubs as registered food businesses within 1.5 miles or so of the middle of Thornhill. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Kitchens in Thornhill get their food hygiene inspections from Southampton council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after photos from each clean are a simple way to show the extract is in hand.
If your kitchen is in a listed or historic building, like the houses around Thornhill (South Stoneham House is about 2.4 miles north-west), fitting access panels needs care. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Thornhill is Moorgreen Hospital, about 1.4 miles north-east. Volunteers running a hall kitchen near St Christopher, or anywhere in Thornhill, may not know when the extract was last cleaned, and a grease test settles it.

Honest limits
It’s worth knowing the limits before booking:
- Ductwork that was poorly designed
- A worn-out fan that needs replacing
- Faulty fire dampers

Where we work
- Bends and junctions
- Horizontal duct runs
- Vertical risers

Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.

Thornhill questions
Who inspects food businesses in Thornhill?
In Thornhill, it’s Southampton council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you get to a site in Thornhill?
Yes. Villages and rural sites across the South East are part of our work, Thornhill included. Photos of the system and directions to the site help us plan the visit.
What shows that the ducts need a clean?
Start with the date of the last clean. No record, or a passed date, means it’s due, and grease readings will confirm how urgent it is.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Is a quote from pictures possible?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote normally follows within one working day. Some sites still need a visit, and we will say so.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
What’s involved in cleaning extract ducts?
Through access panels along the duct. Heavy grease is scraped out by hand, then the surfaces are degreased with a method that suits the deposit, such as degreasers, hot water or steam.
How far ahead should we book?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Have the grease measured if cooking hours go up
- Keep the fan on while anything is cooking
- Do not block access panels with shelving or stock
- Consider fitting panels where the report shows gaps
Every panel we open is refitted when we finish, and the surrounding area is left clean. Waste grease and water are taken away.
Watch for warning signs between cleans: grease leaking from duct joints, smells, or a fan that sounds rough. A grease thickness test can confirm whether a spot clean is needed.
What happens on the day
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a shift or more, depending on the length of the runs and the number of access points. Evenings, weekends or a closed day all work for a site in a place like Thornhill.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- We open the panels and scrape out the heaviest grease.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
Getting ready for the visit
- Clear the space around the work
- Agree a time when the area can be out of use
- Let us know about parking and loading
Getting a quote
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 many jobs can be priced from that alone.
Advice
What the work involves, part by part
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
Multi-storey and shared buildings
In a shared building, the duct links the kitchen to other spaces, so the responsible person has more reason to keep it clean. Your certificate and report give building managers the record they need.
