Duct cleaning in Sherborne St John
Ductwork cleaning across Sherborne St John and nearby, timed so the site keeps working and finished with a written report and pictures.
- Duct runs with no cleaning record
- Thick deposits at the bottom of a vertical duct
- High readings at a recent grease test
What happens on the day
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a few hours for a short run, longer for long runs and tall risers. Pictures of the system and its access let us plan the work in Sherborne St John before we set off.
- 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.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Let us know about parking and loading
- Have your last certificate or report to hand

What affects the quote in Sherborne St John
The price is fixed before any work begins. It takes into account:
- The scale of the work
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
- The condition we find in the survey
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before work begins.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- The paperwork from the last visit, if you have it
- Wide photos of the system and the area around it
- The site address and the type of premises
- The times we could work without disrupting the site
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Then call 0345 646 2711, or send details by email.
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Flag drips from the duct straight away
- Keep your cleaning records together
- Ask for a grease thickness test if the kitchen gets busier
- Keep access panels clear of stored items
After the clean, the same points are tested again, giving you before and after readings. Before and after pictures sit next to the numbers.
Extra access panels mean more of the duct gets cleaned each time. Grease you can reach is grease that gets removed.
When to call us in Sherborne St John
A vertical riser can run up several floors. Grease clings to the walls and can run down to the base as liquid grease runs down. Access along its height is needed to clean it properly.
It’s time to book a visit if you see:
- Stale grease odours from the duct
- Thick crusts of old grease along the duct
- A duct nobody has opened in years
- Sections of duct with no access panels
Healthcare kitchens, like those at hospitals such as Basingstoke and North Hampshire Hospital (about 1.1 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.

Grease, kitchens and Sherborne St John
The FSA’s food hygiene register includes about 4 pubs and bars across Sherborne St John and its immediate surroundings (about a mile and a half). A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Food hygiene inspections in Sherborne St John are the job of Basingstoke and Deane council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Sherborne St John is covered by Hampshire and Isle of Wight Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Bursars and site managers at schools such as Sherborne St John Church of England Primary School tend to book extract cleaning for when the kitchen is empty. Where a hall near Church of St. Andrew, or anywhere in Sherborne St John, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What else we do in Sherborne St John
How the job changes from site to site
Bends and transitions
Grease tends to pile up at elbows. It’s scraped out and degreased, and readings are taken there before and after.
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.
Questions from Sherborne St John
Can the work in Sherborne St John be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Sherborne St John keeps running as normal. Let us know the hours you’re closed and we will book within them.
Who is the fire and rescue service for Sherborne St John?
Hampshire and Isle of Wight Fire and Rescue Service is the fire and rescue service for Sherborne St John. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Who has the legal duty for fire safety?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Do you cover Sherborne St John?
Yes. We cover Sherborne St John and across Hampshire, within our South East and London area. For a fixed quote, call us on 0345 646 2711 or drop us a line.
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
