Kitchen duct cleaning in Flaunden
Duct Doctor has been cleaning kitchen extract systems since 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’re fully insured, with CHAS, SafeContractor and ISO 9001. The work covers horizontal duct runs, extract fans and plenums and filters, and the jobs we see most are grease smells coming from the extract and an inspection that picked up a dirty extract. Need a TR19 duct cleaning contractor for Flaunden? Duct Doctor has covered London and the South East since 2009, with a certificate and photo report after every clean.
Before we clean, we look at where the grease is: wet film or deposit thickness readings show which parts of the duct need the most attention, and readings afterwards go into your report.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Grease, kitchens and Flaunden
Food Standards Agency records list about 3 restaurants, cafés and works canteens across Flaunden and its immediate surroundings (about a mile and a half). Any of them cooking under a canopy is sending grease into its ductwork every service. In Flaunden, food businesses are inspected by environmental health officers from Dacorum council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Flaunden is covered by Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Chenies Manor House, about 1.6 miles south, is one of the historic houses near Flaunden; if you run event catering at a venue like that, cleans can be booked between functions. A hospital like Hemel Hempstead Hospital, about 4.5 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Flaunden is about 3 miles north-east of Amersham, in Hertfordshire. Whatever kind of site you run in Flaunden, we can take on kitchen extract cleaning.

Questions from Flaunden
Which fire service covers Flaunden?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Flaunden. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Is Flaunden within the area you cover?
Yes, we work in villages as well as towns, and Flaunden is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you quote from photos?
Normally, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we normally come back within one working day. Some sites still need a visit, and we’ll say so.
What about areas you cannot get to?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
Do you clean the whole extract system or just the canopy?
Every part the air passes through, as far as access allows. Where there aren’t enough access panels to reach a section, it’s recorded, and we can fit new ones.
What paperwork comes with a kitchen extract clean?
Yes, a TR19 certificate, along with a photo report. The report lists what was cleaned, anything we couldn’t reach and when the next clean is due.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Why it’s worth doing now in Flaunden
Putting it off simply moves the grease further down the duct. Fat that was soft and easy to remove hardens with heat and time, and that takes more work to shift. Staying on a regular cycle keeps each clean manageable. A fault that closes a site in a village like Flaunden affects everyone who depends on it.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711, or email photos for straight advice and a fixed quote.

When to call us in Flaunden
Grease in an extract starts as vapour. As the air cools on its way through the duct, the fat condenses and sticks, building a layer that gets thicker with every service. Filters catch some of it, but never all.
The symptoms we are asked about most are:
- Ductwork thick with old, hardened grease
- Proof of cleaning requested by an insurer
- Stale cooking odours from the system
- Grease dripping from the canopy or filters
If you run a church or community hall kitchen, near Church of St Mary Magdalene (Church of England) or elsewhere in Flaunden, its extract still collects grease from every lunch and event.
Questions to ask before you book
- Whether the quote is based on a survey or pictures
- When they can work, and whether that’s outside your opening hours
- If the quote is a fixed price or an estimate
- Whether a written report and photos are included
What the work involves, part by part
Schools, hospitals and care homes
Even a kitchen that cooks only a few hours a day needs cleaning at least every 12 months under BESA guidance. Holidays make it simple to schedule.
Extract fan and discharge
At the end of the system is the discharge, which can collect grease and stain the surface around it. It’s cleaned as far as safe access allows, and any limits are recorded.

When something else is needed
We won’t sell you work that doesn’t address the problem, so these are the things it will not cover:
- A duct that’s holed or coming apart
- Extraction that cannot cope with the cooking because of its design
- A grease trap that needs emptying
If you are not sure, just give us a ring on 0345 646 2711, or send details by email and we will give you a straight answer.
Where we work
- Horizontal duct runs
- Extract fans
- Vertical risers
- Discharge points
- Canopies and hoods
- Plenums and filters
How the visit works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes a single shift for most kitchens, with long duct runs and tall risers needing more time. Somewhere as small as Flaunden, the date and timings are agreed with you well before the day.
- First the diagnosis: a survey of the whole system and its access points.
- We record grease levels at set points, then fix the price.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Find the previous report, if there is one
- Clear loose items from the work area
Getting a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
How we price kitchen extract cleaning
A fixed price needs a few facts first. We look at:
- What state the system is in
- How many systems or sites are involved
- A single visit or a regular plan
- Whether we need access equipment or extra panels
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.
What to send for a quote
When you contact us, it’s useful to have:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The site address and the type of premises
- The times we could work without disrupting the site
- Any access panels or hatches you can see
We do not publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, call us on 0345 646 2711, or email photos.
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. Reaching it takes a specialist with the right equipment.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
