Ductwork cleaning in Granborough
Every duct has its own route. A few metres to an outside wall, or a riser up through the building to a roof fan. The survey traces the route, so we know where to get in and how long it will take. The work covers bends and junctions, attenuators and horizontal duct runs, and common reasons people get in touch are an insurer asking for TR19 evidence and grease leaking from duct joints.
In a small place like Granborough, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
The paperwork matters as much as the work. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

How the visit works
Your trading hours come first. 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 job takes anything from a few hours to several visits, depending on the length of duct. We agree a date with you, plan the drive to Granborough and turn up when the site is quiet.
- We map the duct route and check where the access panels are.
- We measure grease thickness at set points before cleaning.
- Through the access panels, thick grease is removed by hand first.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- We test again, take pictures and note any part that couldn’t be reached.
Getting ready for the visit
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards
- Let us know when the site is closed or quiet
Ask for a quote
Getting a quote doesn’t take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Advice
When something else is needed
It’s worth knowing the limits before booking:
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- Faulty fire dampers
- Ductwork that was poorly designed
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly before you book.
Where we work
- Vertical risers
- Multi-storey ducts
- Attenuators
- Horizontal duct runs
- Access panels
- Bends and junctions
Between visits
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
- Get panels fitted where the duct couldn’t be cleaned
- Don’t block access panels with shelving or stock
- Keep your cleaning records together
Any section of duct we couldn’t reach is listed on the report and why. We can fit access panels so those sections are cleaned next time.
Keep to the cleaning interval on the report. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Ductwork cleaning around Granborough
Look up Granborough on the FSA’s food hygiene register and you will find about 6 restaurants, cafés and works canteens and about 5 takeaways in and around Granborough, up to about a mile and a half out. Behind every canopy among them is a run of ductwork that collects grease out of sight. Buckinghamshire Fire and Rescue Service covers Granborough. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from Buckinghamshire council inspect food businesses in Granborough. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
If your kitchen is in a listed or historic building, like the houses around Granborough (Claydon House is about 2.9 miles west), fitting access panels needs care. Volunteers running a hall kitchen near Church of St John the Baptist, or anywhere in Granborough, may not know when the extract was last cleaned, and a grease test settles it. For schools such as Sir Thomas Fremantle School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

How the job changes from site to site
Attenuators and discharge
At the end of the duct is the discharge. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We reach it from the plenum side where possible.

How we price ductwork cleaning
A fixed price needs a few facts first. We look at:
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- The condition of the system
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, call 0345 646 2711, or send details by email for straight advice and a fixed quote.
Asking for a quote
Before you ask for a quote, gather:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- When the site is open and when it’s quiet
- Detail shots of panels, filters and grilles
- The paperwork from the last visit, if you have it
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Common questions in Granborough
Who would carry out a food hygiene inspection at a kitchen in Granborough?
In Granborough, it’s Buckinghamshire council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can the work in Granborough be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Granborough keeps running as normal. Your opening times are the first thing we ask for.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Is Granborough in your area?
Yes. Granborough is part of the area we cover, within the South East and London area we cover.
What’s involved in cleaning extract ducts?
Each section is cleaned through its own panel. Grease is scraped out first, then degreased, with readings taken before and after.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
How do you know if the ductwork needs cleaning?
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.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
In-house cleaning or a specialist?
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
