Ductwork cleaning for kitchens and businesses in Ash
Once air leaves the canopy, it travels through ductwork that most people never see. Every horizontal run and vertical riser collects grease along the way, and that’s where a kitchen fire can travel. We clean it from the inside, through access panels, to BESA TR19® Grease. The work covers bends and junctions, access panels and attenuators, and the jobs we see most are duct runs with no cleaning record and a rancid smell from the extract duct.
For a smaller kitchen near Ash, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

What a clean won’t put right
Before booking, it helps to know what’s not included:
- Leaking duct joints that need repair
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
- Undersized or badly laid-out ducts
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly before booking.

In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Kitchen extracts in Ash
Food Standards Agency records list about 15 restaurants, cafés and works canteens and about 18 takeaways and sandwich shops within about 1.5 miles of central Ash. Behind every canopy among them is a run of ductwork that collects grease out of sight. Surrey Fire and Rescue Service covers Ash. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Kitchens in Ash get their food hygiene inspections from Guildford council. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after photos from each clean are a simple way to show the extract is in hand.
For schools such as Walsh CofE Junior School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. If you run a café or takeaway near Ash station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. A hospital like Guildford Hospital, about 4.8 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Why act early in Ash
Old grease in a duct for a kitchen in Ash does not stay soft. Heat and age turn it into a thick, stubborn crust, so the later the clean, the bigger the job. A planned visit to Ash fits your hours; an emergency does not.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before any work starts.

Common questions in Ash
Which fire service covers Ash?
Ash is in the area of Surrey Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can you get to a site in Ash?
Yes. Ash is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
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.
Can you quote from pictures?
Yes, where the photos show enough. If not, a site survey comes first, then a fixed quote.
How do you know if the ductwork needs cleaning?
We measure it. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
How often does extract ductwork need cleaning?
The duct is cleaned as part of the whole system, at intervals set by BESA guidance, from every 3 months for heavy use to every 12 months for light use. Readings tell you if it needs to be more often.
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Get panels fitted where the duct couldn’t be cleaned
- Flag drips from the duct right away
- Ask for a grease thickness test if the kitchen gets busier
- Run the extract fan throughout service
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
Watch for warning signs between cleans: drips from the ductwork, stale smells or a noisy fan. A grease thickness test can confirm whether a spot clean is needed.
Part by part
Horizontal duct runs
Long horizontal runs need access panels at regular intervals. Where the gaps between panels are too long, we record what couldn’t be reached and can fit extra panels.
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.
What we do, step by step
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. The work itself takes a shift or more, depending on the length of the runs and the number of access points. Because the survey comes first, a visit to Ash can normally be finished without a second trip.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Before we arrive
- Move anything stored near the system
- Let us know about permits to work or site inductions
- Tell us where we can park and unload
