What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Ductwork cleaning in Hertingfordbury
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. The work covers attenuators, horizontal duct runs and vertical risers, and people most often call us about hardened, baked-on grease in long horizontal runs and stale grease odours from the duct.
For a kitchen in or near Hertingfordbury, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Good records are part of the job. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Hertingfordbury: your questions answered
Who enforces fire safety at workplaces in Hertingfordbury?
It’s Hertfordshire Fire and Rescue Service, which covers Hertingfordbury. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can you come to Hertingfordbury after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
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.
Do we need to close while you work?
Typically not. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages so parts stay in use.
What’s TR19?
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 accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What shows that the ducts need a clean?
We measure it. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. A mean above 200 microns, or 500 microns at any point, means it’s due.
Is Hertingfordbury in your area?
Yes. We cover Hertingfordbury and across Hertfordshire, as part of our work across South East England and London. For a fixed quote, give us a ring on 0345 646 2711, or email photos.
Leave it or put it right?
TR19® isn’t law, but the duty to manage fire risk is. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, including the grease inside the extract ductwork. In a place like Hertingfordbury, ductwork and fans are easy to forget until something goes wrong.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before work begins.

How the job changes from site to site
Horizontal duct runs
Long horizontal runs need access panels at regular intervals. Any stretch out of reach is noted and can fit extra panels.
Bends and transitions
Bends, elbows and changes of size are where grease collects most. The air slows and drops its load, so these points get extra attention.
Aftercare tips
To keep the system working properly between visits:
- Get panels fitted where the duct couldn’t be cleaned
- Keep the fan on while anything is cooking
- Store the certificate with the fire risk assessment
- Check readings when the menu changes
The report names every part of the duct that couldn’t be reached and why. We can fit access panels so those sections are cleaned next time.
Keep to the cleaning interval on the report. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
When something else is needed
To be straight with you, there are a few things this work won’t fix:
- A damper stuck open in the duct
- Ductwork that was poorly designed
- A worn-out fan that needs replacing
If you are not sure, just call us on 0345 646 2711, or send details by email and we will give you a straight answer before you book.

Ductwork cleaning around Hertingfordbury
According to Food Standards Agency records, there are about 28 pubs, bars and clubs and about 3 hotels and B&Bs in Hertingfordbury and the streets around it, up to about 1.5 miles out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. In Hertingfordbury, food businesses are inspected by environmental health officers from East Hertfordshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Hertingfordbury falls to 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.
A hall kitchen that only cooks for events, whether near Church of St Mary and St John or elsewhere in Hertingfordbury, still needs its extract cleaned, just less often. For schools such as Hollybush Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. If you run a café or takeaway near Hertford North station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

How we price ductwork cleaning
Sites vary more than people expect. The main factors:
- How easy every part is to reach
- What state the system is in
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we will price it together.
Asking for a quote
What to send for a quote:
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- Any symptoms, from odd noises to smells or leaks
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes from a few hours to more than one visit, depending on duct length and access, and the area is cleaned down before we leave. Seeing the system in photos first means the trip to Hertingfordbury can be planned properly.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- Access panels are opened and heavy deposits scraped out by hand.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Mention any parking or loading restrictions
- Dig out any earlier paperwork for the system
