How it works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes a few hours for a short run, longer for long runs and tall risers. Somewhere as small as South Harefield, the date and timings are agreed with you well before the day.
- We trace the duct and find every way in.
- We take grease readings along the route.
- 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.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear the space around the work
- Find the previous report, if there is one

Ductwork cleaning in South Harefield
Nobody sees duct grease building, so nobody notices it until something goes wrong. Flames pulled in from the cooking line can ignite it, and fire can then run along the ductwork to other parts of the building. Cleaning the duct takes that fuel away. The work covers access panels, multi-storey ducts and bends and junctions, and the jobs we see most are grease leaking from duct joints and readings above 200 microns from a grease thickness test.
In a small place like South Harefield, 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.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
How we price ductwork cleaning
The survey tells us what the work involves. We look at:

- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

- Photos showing the whole system and its surroundings

Grease, kitchens and South Harefield
The FSA’s data shows about 11 pubs and bars registered in and around South Harefield, up to about a mile and a half out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. South Harefield sits within the area of Buckinghamshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Kitchens in South Harefield get their food hygiene inspections from Hillingdon council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you run catering at a healthcare site, such as a hospital like Harefield Hospital about 1.2 miles north, the extract may need cleaning more often than a part-time kitchen. If you run a church or community hall kitchen, near Church of St Mary the Virgin or elsewhere in South Harefield, its extract still collects grease from every lunch and event.

Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Get panels fitted where the duct couldn’t be cleaned
- Never cook with a filter missing
- Keep access panels clear of stored items
- Flag drips from the duct straight away
After the clean, the same points are tested again, giving you before and after readings. Photos of each section go alongside them.
Grease that never reaches the duct never needs cleaning out of it. Keep the filters clean, well fitted and in place whenever you cook.
When something else is needed
Some problems need a different service or another trade:
- Leaking duct joints that need repair
- A failed fan motor at the end of the duct (a fan repair job)
- Duct sealed behind fixed ceilings or walls
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we’ll tell you honestly.

What the work involves, part by part
Multi-storey and shared buildings
A fire in a duct in a shared building can affect far more than one kitchen, so the responsible person has more reason to keep it clean. Your certificate and report give building managers the record they need.
Vertical risers
Risers often pass through floors and walls, where fire dampers may be fitted. Damper testing is a separate service.
Signs you need ductwork cleaning in South Harefield
A vertical riser can run up several floors. Grease clings to the walls and can run down to the base, where it can pool. Access along its height is needed to clean it properly.
Keep an eye out for these warning signs:
- Hardened, baked-on grease in long horizontal runs
- Grease pooling at the foot of the riser
- Ductwork that has never been cleaned
- Grease leaking from duct joints
For schools such as Harefield Infant School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.
