About our ductwork cleaning in Kinsbourne Green
Each extract duct we take on in Kinsbourne Green goes through the full routine: we test the grease first, remove thick deposits by hand and degrease what’s left. Post-clean readings and photos complete the record. If you have grease pooling at the foot of the riser and a rancid smell from the extract duct, we can put it right.
In a small place like Kinsbourne Green, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Questions from Kinsbourne Green
Which fire authority looks after Kinsbourne Green?
Fire safety enforcement in Kinsbourne Green is handled by Hertfordshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can the work in Kinsbourne Green be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. That way a site in Kinsbourne Green doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
What’s involved in cleaning extract ducts?
We open each access panel and clean the section it reaches. Grease is scraped out first, then degreased, with readings taken before and after.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
Do you survey before quoting?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Do you install duct access panels?
Yes. We’ll point out where panels are needed, and we can fit them so those sections are cleaned in future.
Is TR19 cleaning required by law?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes from a few hours to more than one visit, depending on duct length and access. We agree a date with you, plan the drive to Kinsbourne Green and turn up when the site is quiet.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Before we arrive
- Let us know about permits to work or site inductions
- Clear loose items from the work area
- Tell us where we can park and unload

Hertfordshire Fire and Rescue Service covers Kinsbourne Green.

What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Leave it or put it right?
A partly blocked duct slows the airflow. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy, and grease may start to leak from joints. A planned visit to Kinsbourne Green is easier to arrange than an emergency callout.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

Common problems we fix in Kinsbourne Green
Slow air leaves the most grease behind. Flat runs, bends, reducers and the base of risers are the usual hotspots, and those are the points we pay most attention to.
Common reasons sites call us are:
- Grease seeping out of the duct seams
- Proof of duct cleaning for the insurer
- Stale grease odours from the duct
- A duct nobody has opened in years
Historic houses near Kinsbourne Green, such as Childwickbury Manor about 4.1 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
