Ductwork cleaning in Great Offley, Hertfordshire
Looking for ductwork cleaning in Great Offley? We survey first, send you a fixed quote and work around your opening hours, then sign off with a report and photos.
- Hardened, baked-on grease in long horizontal runs
- Gaps where access panels were never fitted
- Smells of old cooking grease from the ductwork
The process
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes a shift or more, depending on the length of the runs and the number of access points. For a village or hamlet like Great Offley, tell us about narrow lanes, gates and parking when you book.
- First the duct route is traced and every access point noted.
- Grease readings are taken at set points along the duct.
- Access panels are opened and heavy deposits scraped out by hand.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Mention any parking or loading restrictions
- Mention any locked doors, roof access or ceiling voids
Getting a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

About our ductwork cleaning in Great Offley
The ductwork is where an extract clean is won or lost. 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. If you are dealing with proof of duct cleaning for the insurer and years of grease along the duct floor, we can help.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Between visits
Think of this as the after-treatment advice, in brief:
- Store the certificate with the fire risk assessment
- Never cook with a filter missing
- Tell us if grease leaks from the ductwork
- Keep access panels clear of stored items
The report names every part of the duct that couldn’t be reached and why. You can then decide whether to have access panels fitted.
The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.
What ductwork cleaning cannot fix
We will always give you a straight diagnosis, so here’s what ductwork cleaning will not do:
- A duct that’s too small or badly routed for the kitchen (a design issue)
- An extract fan that has stopped working
- Fire dampers that do not close (they need testing and remedials)
If in doubt, call 0345 646 2711 or email us and we’ll say what we think before booking.

What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
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.
Questions from Great Offley
Which fire service covers Great Offley?
Great Offley is in the area of Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can the work in Great Offley be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
How long will the duct clean take?
Short runs are quick, while long ducts and tall risers can need more than one visit. Visits are planned out of hours.
How is kitchen extract ductwork cleaned?
We get into the duct through its access panels. Heavy grease is scraped out by hand, then the surfaces are degreased with a method that suits the deposit, such as degreasers, hot water or steam.
What’s the cleaning interval for extract ductwork?
The minimum depends on how long the kitchen cooks each day: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Measured grease sets the real interval.
What shows that the ducts need a clean?
The date on the last certificate is the first thing to check. If it’s overdue, or there isn’t one, a clean is due, and grease readings will confirm how urgent it is.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.

How the job changes from site to site
Multi-storey and shared buildings
A duct that climbs several floors may be cleaned over more than one visit. We agree a sequence that suits the building, out of hours where possible.
Vertical risers
Risers carry the extract up through the building to the roof. Grease runs down the walls and gathers at the base, which is one of the points we test.
