Ductwork cleaning for kitchens and businesses in Colney Butts
Nobody sees duct grease building, so nobody notices it until something goes wrong. A flare-up drawn up from the range can light it, and fire can then run along the ductwork to other parts of the building. Removing it is the whole point. If you have grease seeping out of the duct seams and a duct clean needed for an insurer, we can help, from horizontal duct runs, attenuators and multi-storey ducts onwards.
In a smaller place like Colney Butts, 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.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What we are called out for in Colney Butts
Grease in a duct running from a kitchen in Colney Butts is as much a fire risk as in any building. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
Look out for these warning signs:
- A duct nobody has opened in years
- Readings above 200 microns from a grease thickness test
- Smells of old cooking grease from the ductwork
- A duct clean needed for an insurer
If you run catering at a healthcare site, such as a hospital like Watford General Hospital about under half a mile south-west, the extract may need cleaning more often than a part-time kitchen.
What to look for in a quote
- What’s included in the scope, part by part
- Whether inaccessible sections are listed on the report
- Whether the figure could change on the day
- Whether a survey comes first
How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes a few hours for a short run, longer for long runs and tall risers. Tell us about any gates, ladders or locked plant areas at your site near Colney Butts when you book.
- 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.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Before we arrive
- Name a contact who can let us in at the agreed time
- Have your last certificate or report to hand
- Mention any sign-in, permit or induction we need
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

What affects the quote in Colney Butts
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether several sites go on one quote
- The size of the system
- A single visit or a regular plan
- Where the site is and how we reach it
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
- The site address and the type of premises
- Detail shots of panels, filters and grilles
We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, call 0345 646 2711 or email us.
Colney Butts kitchens: local notes
Food Standards Agency records include about 44 pubs, bars and clubs and about 6 hotels and guest houses within about 1.5 miles of central Colney Butts. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Colney Butts, food businesses are inspected by environmental health officers from Watford council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector. The fire and rescue service for Colney Butts is Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Where a hall near St Mary's Church, or anywhere in Colney Butts, hosts lunch clubs or events, its extract gathers grease just as a café’s does. School kitchens, at schools like Watford Grammar School for Girls for example, are normally cleaned in the holidays so no lunches are lost.

Around Colney Butts

What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Check readings when the menu changes
- Tell us if grease leaks from the ductwork
- Keep to the interval on the report
- Ask us about extra access panels where sections cannot be reached
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.
Book the next duct clean before the date passes. 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
Ductwork cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- A worn-out fan that needs replacing
- Duct sealed behind fixed ceilings or walls
- Undersized or badly laid-out ducts
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we will tell you honestly before booking.

Why act early in Colney Butts
A fire in a greasy duct is hard to reach and hard to stop. It can travel through the ductwork to other parts of the building, which is why the duct matters as much as the canopy. Booking ahead lets us plan the trip to Colney Butts at a time that suits you.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before work begins.

Questions from Colney Butts
Who would carry out a food hygiene inspection at a kitchen in Colney Butts?
In Colney Butts, it’s Watford council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Is Colney Butts within the area you cover?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Where does the waste go?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
What paperwork do you give after a duct clean?
A photo report, with readings and before and after photos, plus a TR19 certificate for a full system clean. The report says when the next clean is due.
Will the duct clean disrupt the kitchen?
When the kitchen is closed. Larger systems may be cleaned over several nights, with the kitchen ready to cook each morning.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
What happens if you can’t reach some of it?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
