Hertfordshire · Ductwork cleaning
Green Tye ductwork cleaning
Our technicians work in Green Tye on cleaning of kitchen extract ductwork, horizontal runs and vertical risers through access panels. Out-of-hours visits, a fixed quote and a written report with photos on every job.
- Hardened, baked-on grease in long horizontal runs
- Readings above 200 microns from a grease thickness test
- Stale grease odours from the duct
When it’s something else
To be straight with you, there are a few things this work will not fix:
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- Fire dampers that don’t close (they need testing and remedials)
- Ductwork that was poorly designed
If in doubt, ring 0345 646 2711 or email us and we will say what we think.
Parts of the system we cover
- Vertical risers
- Attenuators
- Multi-storey ducts
- Bends and junctions
- Access panels
- Horizontal duct runs
Ductwork cleaning in Green Tye, done properly
Not every duct has enough access panels. TR19 calls for any section we couldn’t reach to be recorded, and new panels can be fitted to reach it in future. It’s better to know than to assume. If you have grease seeping out of the duct seams and a rancid smell from the extract duct, 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 paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

How the visit works
A visit follows the same order every time: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes a few hours for a short run, longer for long runs and tall risers. A few photos of the system help us make the most of a visit to a place like Green Tye.
- 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.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Before we arrive
- Arrange a key holder or contact on site
- Tell us the best time to work, such as after service or at a weekend
- Mention any locked doors, roof access or ceiling voids

What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Your questions about ductwork cleaning in Green Tye
Can the work in Green Tye be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Green Tye needn’t be disturbed. Just call 0345 646 2711 or drop us a line with your opening times and we will plan around them.
Who enforces fire safety at workplaces in Green Tye?
Green Tye is in the area of Hertfordshire 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.
Do you install duct access panels?
Yes, extra panels can be fitted. It means more of the duct can be cleaned next time, and the report will show where they’re needed.
How often should kitchen ducts be cleaned?
It depends mostly on daily cooking hours. Kitchens cooking 12 to 16 hours a day need it at least every 3 months, while lighter use can go longer.
How long will the duct clean take?
It depends on the length of the duct, the number of access panels and how much grease there is. Typically it takes from a few hours to more than one visit, depending on duct length and access.
Is TR19 cleaning required by law?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005, which applies in England and Wales.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
How is kitchen extract ductwork cleaned?
Each section is cleaned through its own panel. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.
When to call us in Green Tye
Grease settles fastest where the air slows down. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
What we’re most often called out for:
- Grease seeping out of the duct seams
- Stale grease odours from the duct
- Ductwork that has never been cleaned
- Gaps where access panels were never fitted
Historic houses near Green Tye, such as Much Hadham Palace about 1.3 miles north-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Take a look at what affects the cost or our accreditations.
What affects the cost of ductwork cleaning
You will get a fixed price before we start. It takes into account:
- Whether we need access equipment or extra panels
- The times the site is available
- Site rules, permits and inductions
- The condition we find in the survey
What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before any work starts.
What to send for a quote
What to send for a quote:
- The times we could work without disrupting the site
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
How the job changes from site to site
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.
Vertical risers
Risers often pass through floors and walls, where fire dampers may be fitted. Damper testing is a separate service.
