How we price ductwork cleaning
A fixed price needs a few facts first. We check:
- A single visit or a regular plan
- Working hours and out-of-hours timing
- What state the system is in
- How many systems or sites are involved
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
What we need to know
There’s no need for technical detail. Just send:
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The paperwork from the last visit, if you have it
- Your opening hours and when the area is out of use
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Ductwork cleaning for kitchens and businesses in Felden
Once air leaves the canopy, it travels through ductwork that most people never see. Every horizontal run and vertical riser collects grease along the way and a fire in the duct can spread through the building. We clean it from the inside, through access panels, to BESA TR19® Grease. If you’re dealing with duct runs that can’t be reached and smells of old cooking grease from the ductwork, we can put it right, from attenuators, horizontal duct runs and vertical risers onwards.
In a smaller place like Felden, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
What we are called out for in Felden
Many ducts do not have enough access panels. Stretches with no way in may never have been touched, and the grease there keeps building out of sight.
Most sites get in touch when they notice one of these:
- Readings above 200 microns from a grease thickness test
- Duct runs with no cleaning record
- Grease seeping out of the duct seams
- Stale grease odours from the duct
Where a hall near Church of St Mary, or anywhere in Felden, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Questions to ask before booking
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What happens if part of the system cannot be accessed
- When the next visit should be, and why
- What’s included in the scope, part by part
What happens if it’s left?
Old grease in a duct for a kitchen in Felden does not stay soft. Heat and age turn it into a thick, stubborn crust, so the later the clean, the bigger the job. A planned visit to Felden fits your hours; an emergency doesn’t.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before we start.

How the visit works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes a few hours for a short run, longer for long runs and tall risers. Tell us when your site near Felden is quiet and the visit will be booked for then.
- 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.

- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool

Advice
Common questions in Felden
Who is the fire and rescue service for Felden?
Fire safety enforcement in Felden is handled by Hertfordshire Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Can you clean school kitchen extracts in Felden during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Felden, the Food Standards Agency lists about 17 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What information do you need?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
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 have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How the job changes from site to site
Attenuators and discharge
Near the discharge, the air has cooled the most, which can mean heavier deposits. We include it in the clean and the readings.
Access panels
Panels have to seal properly once they’re closed so the duct stays tight. We’ll tell you if any panel needs replacing.
When something else is needed
In fairness, there are a few things this work won’t fix:
- Undersized or badly laid-out ducts
- An extract fan that has stopped working
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we will tell you honestly.
Where we work
- Access panels
- Horizontal duct runs
- Attenuators
- Vertical risers
- Bends and junctions

Grease, kitchens and Felden
The FSA’s data shows about 16 pubs and bars registered across Felden and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. In Felden, 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. A dated certificate in the maintenance file answers the question before it’s asked. Felden sits within the area of Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Bursars and site managers at schools such as Nash Mills Church of England Primary School tend to book extract cleaning for when the kitchen is empty. For kitchens close to Apsley station, where the day often starts early and ends late, the extract can be cleaned overnight.
