About our ductwork cleaning in California
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Grease settles along every metre of it, and that is where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. We are often asked to deal with sections of duct with no access panels and stale grease odours from the duct, across access panels, vertical risers and multi-storey ducts.
In a smaller place like California, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What ductwork cleaning looks like in California
Look up California on the FSA’s food hygiene register and you will find about 92 cafés, restaurants and staff canteens and about 57 takeaways within about 1.5 miles of central California. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. It’s Buckinghamshire council that sends environmental health officers to food businesses in California. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Buckinghamshire Fire and Rescue Service covers California. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
For schools such as Oak Green School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. For kitchens close to Aylesbury station, where the day often starts early and ends late, the extract can be cleaned overnight.
California is about 1 mile south of Aylesbury, in Buckinghamshire. We carry out ductwork cleaning for businesses, landlords and public buildings in California and the rest of Buckinghamshire. California is one of 263 towns, villages and districts in Buckinghamshire where we work for commercial clients. Milton Keynes is in our area too, about 16 miles from California.
Here we cover the HP21, HP20 and HP19 postcode area for ductwork cleaning. If you need ductwork cleaning at premises on Lee Road, Penn Road and Eaton Road or a nearby road, our technicians can take on the work. California sits on or near the A41 and A418, which makes travel easy for ductwork cleaning. We also cover the places around California: Aylesbury (1 mile north), Walton (1 mile east), Queens Park (1 mile east), Southcourt (1 mile south) and New Zealand (1 mile north). Within a short drive, we also cover High Wycombe (13 miles south), Chesham (11 miles south-east), Buckingham (15 miles north-west), Amersham (13 miles south-east), Princes Risborough (6 miles south) and Haddenham (6 miles south-west).
Landmarks near California
Around California, our work takes us to kitchens and buildings near Pebble Brook School, Buckinghamshire UTC and King's Head Inn and the streets around them. California has its own railway station: Aylesbury station. A little further out are Friars Square (within half a mile north-east) and Dinton Castle (3.4 miles west). The countryside around California includes Beacon Hill.
When to call us in California
Grease filters that do not seal let fat straight through. The duct then takes grease that the filters should have stopped and it fills faster.
Signs it’s time to call us include:
- High readings at a recent grease test
- Sections of duct with no access panels
- A duct nobody has opened in years
- Hardened, baked-on grease in long horizontal runs
A hall kitchen that only cooks for events, whether near Church of St Mary or elsewhere in California, still needs its extract cleaned, just less often.
Questions to ask before booking
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the price is fixed
- Whether the quote shows VAT
- How they set the interval to the next visit
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Managing agents and facilities teams in California
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
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 can quote for the whole system.
California: your questions answered
Which fire authority looks after California?
Buckinghamshire Fire and Rescue Service is the fire and rescue service for California. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Can you work in California outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in California does not have to lose a day’s trading. Your opening times are the first thing we ask for.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
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.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Can you quote from photos?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How the visit works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes from a few hours to more than one visit, depending on duct length and access. Tell us when your site near California is quiet and the visit will be booked for then.
- First we diagnose: the route, the access and the grease levels.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, photos and a recommended next clean date complete the job.
How to prepare
- Name a contact who can let us in at the agreed time
- Tell us about site rules, permits or sign-in
- Have your last certificate or report to hand
Ask for a quote
To help us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, ring 0345 646 2711 or use the quote form.
Advice
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Keep access panels clear of stored items
- Book the next clean before the recommended date
- Consider fitting panels where the report shows gaps
- Never cook with a filter missing
After the clean, the same points are tested again, giving you before and after readings. Photos of each section go alongside them.
Have access panels fitted where sections cannot be reached. It doesn’t stop grease forming, but it stops it building unseen.
What the work involves, part by part
Access panels
Every section of duct is cleaned through an access panel. Where there are none, those sections cannot be cleaned and the report has to say so.
Horizontal duct runs
A long flat run can’t be cleaned from one end. Any stretch out of reach is noted and can fit extra panels.

How we price ductwork cleaning
The diagnosis comes before the price. We look at:
- Where the site is and how we reach it
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
- How many systems or sites are involved
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- 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
- Any access panels or hatches you can see
- The postcode and the type of business
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.
