How we handle ductwork cleaning in Nettleden
No two duct runs are the same, in Nettleden or anywhere else. Some run a short distance to an outside wall, others climb several floors to the roof. We map the route during the survey, so we know where to get in and how long it will take. The work covers multi-storey ducts, access panels and bends and junctions, and the jobs we see most are a duct nobody has opened in years and proof of duct cleaning for the insurer.
In a village or hamlet like Nettleden, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Different parts, different methods
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. The paperwork suits landlords and managing agents.
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
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. That’s our job.
How the visit works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes anything from a few hours to several visits, depending on the length of duct. If the van will struggle with a lane or gateway near Nettleden, let us know and we’ll plan around it.
- First the duct route is traced and every access point noted.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- We test again, take photos and note any part that couldn’t be reached.
How to prepare
- Tell us about site rules, permits or sign-in
- Clear loose items from the work area
- Let us know when the site is closed or quiet
How to get a quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price, before work begins.

Do you work overnight in Nettleden?

Do you do school kitchen extract cleaning in Nettleden in the summer holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Nettleden. Booking early in the term gives the best choice of holiday dates.

What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.
What should I send you?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
Do you survey before quoting?
Yes. We always survey first, either from pictures and details you send or on a site visit. A fixed quote follows.
For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.

Other services in Nettleden
Grease, kitchens and Nettleden
Food Standards Agency records include about 5 pubs and bars in and around Nettleden, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Hertfordshire Fire and Rescue Service covers Nettleden. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. In Nettleden, food businesses are inspected by environmental health officers from Dacorum council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand.
If you run catering at a healthcare site, such as a hospital like Hemel Hempstead Hospital about 3.1 miles south-east, 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 Lawrence or elsewhere in Nettleden, its extract still collects grease from every lunch and event.

Signs you need ductwork cleaning in Nettleden
Grease in a duct running from a kitchen in Nettleden is as much a fire risk as in any building. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
Clients usually contact us when they notice one of these:
- A duct nobody has opened in years
- Proof of duct cleaning for the insurer
- Duct runs that cannot be reached
- A rancid smell from the extract duct
For schools such as Great Gaddesden Church of England Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.
Questions to ask before booking
- What’s included in the scope, part by part
- Whether they’re fully insured
- What paperwork you get at the end
- Whether the work can be done while the site is closed
What happens if it’s left?
Old grease in a duct for a kitchen in Nettleden does not stay soft. It bakes into a hard layer that takes far longer to remove, so the later the clean, the bigger the job. Equipment tucked in a roof space or outbuilding near Nettleden rarely gets looked at unless someone books it.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, give us a ring on 0345 646 2711 or email us for straight advice and a fixed quote.
