How we handle ductwork cleaning in Amwell
If the ducts in Amwell haven’t been cleaned for a while, or nobody is sure when they were? Tell us about the system when you call 0345 646 2711 or email us, and we’ll give you a fixed quote for ductwork cleaning, normally within one working day. The work covers bends and junctions, horizontal duct runs and multi-storey ducts, and common reasons people get in touch are duct runs that can’t be reached and a rancid smell from the extract duct.
Work in a small place like Amwell starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
The paperwork matters as much as the work. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Staff cleaning versus specialist work
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.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Honest limits
We’d rather tell you now than book work that will not help, so here are the limits:
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- A worn-out fan that needs replacing
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.
Where we work
- Bends and junctions
- Vertical risers
- Multi-storey ducts
- Access panels
- Horizontal duct runs
- Attenuators
Why it’s worth doing now in Amwell
A partly blocked duct slows the airflow. Less air moves, so heat and smoke stay in the kitchen while the fan strains, and grease may start to leak from joints. Out of sight is the usual reason a rural system goes too long without attention.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before work begins.
Why us?
- Full insurance on every job
- Fixed quotes, normally within one working day
- Ventilation hygiene specialists since 2009
- A written report with pictures after every visit

Aftercare tips
Once we’ve finished, these simple steps help:
- Ask for a grease thickness test if the kitchen gets busier
- Tell us if grease leaks from the ductwork
- File each certificate and photo report in the maintenance log
- Diarise the next duct clean
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.
Run the extract the whole time the kitchen is cooking. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
Questions from Amwell
Do you do school kitchen extract cleaning in Amwell in the summer holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Amwell. Just ring 0345 646 2711, or send details by email with your term dates and we’ll plan around them.
Do you work in villages like Amwell?
Yes, we work in villages as well as towns, and Amwell is covered. Photos of the system and directions to the site help us plan the visit.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
How long does ductwork cleaning take?
It depends on the length of the duct, the number of access panels and how much grease there is. As a guide, it takes a few hours for a short run, longer for long runs and tall risers.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
What shows that the ducts need a clean?
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.
When is the ductwork cleaned?
Out of hours, at a time that suits the kitchen. Larger systems may be cleaned over several nights, with the kitchen ready to cook each morning.
Can you clean ductwork with no access panels?
Sections out of reach are written down on the report, as TR19 expects. We can fit new access panels so they’re cleaned next time.
What affects the cost of ductwork cleaning
Before we fix a price, we need to know a few things. We check:
- Site requirements such as sign-in and permits
- The condition of the system
- How many systems or sites are involved
- The times the site is available
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
We can often survey from photos. Try to include:
- The postcode and the type of business
- Your opening hours and when the area is out of use
- Wide photos of the system and the area around it
- Any previous report or certificate
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, you get a fixed price before we start.

When to call us in Amwell
A greasy duct is a fire path, in Amwell as anywhere. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
These are the problems we see most often:
- Readings above 200 microns from a grease thickness test
- Stale grease odours from the duct
- Heavy grease at the base of a riser
- Duct runs with no cleaning record
Healthcare kitchens, like those at hospitals such as St Albans City Hospital (about 3.4 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.
Before you book anyone
- Whether the figure could change on the day
- Proof of accreditation you can verify
- When they can work, and whether that is outside your opening hours
- When the next visit should be, and why
Grease, kitchens and Amwell
The Food Standards Agency lists about 3 bars, pubs and nightclubs as registered food businesses across Amwell and its immediate surroundings (about a mile and a half). A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. It’s St Albans City council that sends environmental health officers to food businesses in Amwell. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Amwell falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you look after a school kitchen, at a school such as St Helen's Church of England Primary School or anywhere near Amwell, the holidays are the usual time for a TR19® clean. Childwickbury Manor, about 2.6 miles south-west, is one of the historic houses near Amwell; if you run event catering at a venue like that, cleans can be booked between functions.

How the visit works

- 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, pictures and a recommended next clean date complete the job.
Before we arrive
- Agree a time when the area can be out of use
- Clear the space around the work
