About our ductwork cleaning in Little Amwell
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Grease settles along every metre of it and a fire in the duct can spread through the building. We clean it from the inside, through access panels, to BESA TR19® Grease. Common call-outs are for an insurer asking for TR19 evidence and grease pooling at the foot of the riser, on horizontal duct runs, access panels and multi-storey ducts.
In a small place like Little Amwell, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. 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. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes from a few hours to more than one visit, depending on duct length and access. A quick note on how to find the site and where to park makes a visit to Little Amwell run smoothly.
- First the duct route is traced and every access point noted.
- Grease readings are taken at set points along the duct.
- Access panels are opened and heavy deposits scraped out by hand.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- 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
- Dig out any earlier paperwork for the system
- Mention any locked doors, roof access or ceiling voids

How the job changes from site to site
Attenuators and discharge
The last section of duct before the discharge is often the coolest, so it can collect more grease than expected. We include it in the clean and the readings.
Horizontal duct runs
Grease settles on the floor of a flat duct run. We scrape out the heavy layer first, then the walls and roof are cleaned too.

Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Ask for a grease thickness test if the kitchen gets busier
- Keep the fan on while anything is cooking
- File each certificate and photo report in the maintenance log
- Diarise the next duct clean
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
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.
Signs you need ductwork cleaning in Little Amwell
Many ducts don’t have enough access panels. Stretches with no way in may never have been touched, and grease there keeps thickening unseen.
Clients normally contact us after spotting something like this:
- An insurer asking for TR19 evidence
- Duct runs that cannot be reached
- A grease test showing the duct is overdue
- Fat dripping from the ductwork
Where a hall near Church of the Holy Trinity, or anywhere in Little Amwell, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
