Ductwork cleaning in Wallington, Hertfordshire
Ductwork cleaning for Wallington, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- A rancid smell from the extract duct
- High readings at a recent grease test
- Grease pooling at the foot of the riser
What a clean will not put right
Not every problem is solved by ductwork cleaning, and we’d rather say so up front. It will not put right:
- Fire dampers that don’t close (they need testing and remedials)
- Ductwork that was poorly designed
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
If in doubt, call us on 0345 646 2711 or use the quote form and we’ll say what we think before booking.

How we handle ductwork cleaning in Wallington
Duct cleaning is the hardest part of an extract clean, and the part most often skipped. Sections with no way in can go uncleaned for years. Each section we can reach is cleaned, and any we can’t is written down, so you know exactly where you stand. The work covers attenuators, access panels and horizontal duct runs, and the jobs we see most are hardened, baked-on grease in long horizontal runs and a duct clean needed for an insurer.
In a small place like Wallington, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from a few hours to several visits, depending on the length of duct. Pictures of the system and its access let us plan the work in Wallington before we set off.
- 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.
- Bends, risers and the base of each riser get extra attention.
- Readings, photos and a recommended next clean date complete the job.
Getting ready for the visit
- Let us know about parking and loading
- Clear loose items from the work area

How to get a quote
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, you get a fixed price before work begins.

Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep the fan on while anything is cooking
- Keep to the interval on the report
- Get panels fitted where the duct couldn’t be cleaned
- Never cook with a filter missing
The report gives a recommended next clean date, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Keep to the cleaning interval on the report. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.

Kitchen extracts in Wallington
Wallington is about 34 miles from central London, well within the area we cover across London and the South East. Visits are booked around your hours, evenings and weekends included. Wallington is covered by Hertfordshire Fire and Rescue Service. 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.
A hall kitchen that only cooks for events, whether near Church of St Mary or elsewhere in Wallington, still needs its extract cleaned, just less often. If your kitchen is in a listed or historic building, like the houses around Wallington (Hinxworth Place is about 4.9 miles north-west), fitting access panels needs care. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Wallington is Fairfield Hospital, about 5.6 miles west.

Part by part
Vertical risers
Cleaning a riser needs access along its height. Any part that cannot be safely reached is recorded.
Horizontal duct runs
A long flat run cannot be cleaned from one end. Where the gaps between panels are too long, we record what couldn’t be reached and can fit extra panels.
What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Why it’s worth doing now in Wallington
A fire in a greasy duct is hard to reach and hard to stop. The duct can carry it to rooms, floors or roof spaces well away from the kitchen, so cleaning the duct is as important as cleaning the hood. A planned visit to Wallington is easier to arrange than an emergency callout.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.

Wallington: your questions answered
Who inspects food businesses in Wallington?
That’s North Hertfordshire council, whose environmental health officers carry out food hygiene inspections in Wallington. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can you get to a site in Wallington?
Yes, Wallington is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Is a quote from pictures possible?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.
How can I tell if my extract ducts are dirty?
A grease thickness test gives the answer. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
Are you fully insured?
Yes, we are fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.
How often should kitchen ducts be cleaned?
BESA guidance sets minimum intervals by daily cooking hours: 3-monthly for heavy use, 6-monthly for moderate and 12-monthly for light use. Grease readings may show it needs doing sooner.
What’s involved in cleaning extract ducts?
We get into the duct through its access panels. Thick deposits are removed by hand before degreasing, such as degreasers, hot water or steam.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
