Commercial kitchen extraction cleaning in Croxley Green
A kitchen extract system is far more than the canopy you can see. Behind it sit the plenum and grease filters, then the ductwork, risers, extract fan and discharge, and each part collects grease. Our clean follows the air from canopy to discharge, cleaning to BESA TR19® Grease. The work covers vertical risers, discharge points and horizontal duct runs, and people most often call us about an extract that has never been cleaned to TR19 and extraction mentioned at an environmental health visit. Need a TR19 duct cleaning contractor for Croxley Green? Duct Doctor has covered London and the South East since 2009, with a certificate and photo report after every clean.
Each job starts with a look at where grease has built up: grease readings at set points tell us where the heaviest deposits are, and the same readings after the clean show the result.
Somewhere as small as Croxley Green, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Part by part
Ductwork and risers
Long flat runs of duct are where grease collects. Each run is cleaned through its access panels, recording any that can’t be reached.
Canopy and plenum
Canopies vary from a single hood to long runs over several appliances, every section is cleaned and recorded in the photo report before and after.
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep the cleaning records where you can find them
- Don’t let the canopy gutters overflow
- Clean grease off the canopy surfaces regularly
- Diarise the next clean as soon as you get the certificate
A TR19 certificate notes the date, the location and the technician. File it with the fire risk assessment and the maintenance log, so it’s to hand when an insurer, fire officer or EHO asks.
Keep the outside of the canopy wiped and any grease cups emptied. A daily wipe is not a deep clean, but it helps between visits.
Croxley Green questions
Will you come out to Croxley Green?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you work overnight in Croxley Green?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
Are you a BESCA Vent Hygiene Elite member?
As a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, our work sits within an independently audited scheme. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Which parts of the extract do you clean?
A TR19 Grease clean covers the full extract route, not just the canopy. Canopy, plenum, filters, ductwork, risers, fan and discharge are all included, reached through access panels where needed.
What should I send you?
A short description and a few photos plus the address and your hours. We’ll ask for anything else we need.
How long does it take to clean a kitchen extract system?
That depends on the size of the system, the amount of grease and the number of access points. As a guide, it takes anything from a few hours to a full night, depending on the size of the system.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
What do I get after the clean?
You receive a TR19 certificate and a photo report. Certificates are issued through the BESCA Vent Hygiene Elite portal, and the report includes before and after pictures, grease readings and the recommended next clean date.

Fixed quotes for kitchen extract cleaning in Croxley Green
The survey tells us what the work involves. The main factors are:
- Whether several sites go on one quote
- How big the system is
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- Your opening hours and when the area is out of use
- Wide photos of the system and the area around it

What kitchen extract cleaning looks like in Croxley Green
Food Standards Agency records list about 48 cafés, restaurants and staff canteens and about 15 takeaways and sandwich shops across Croxley Green and its immediate surroundings (about a mile and a half). Those that fry, grill or roast under a canopy need their extracts cleaned at intervals set by how long they cook. Environmental health officers from Three Rivers council inspect food businesses in Croxley Green. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Croxley Green sits within the area of Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If you run catering at a healthcare site, such as a hospital like Watford General Hospital about 1.8 miles east, the extract may need cleaning more often than a part-time kitchen. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Chenies Manor House is about 4.2 miles north-west), access may need planning. Where a hall near St Oswald's Parish Church, or anywhere in Croxley Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Croxley Green is about 1 mile north-east of Rickmansworth, in Hertfordshire. Every kind of commercial site in Croxley Green, kitchen extract cleaning is something we can help with. Visits can be booked for evenings, overnight or weekends so trading isn’t interrupted. Across Hertfordshire, we cover 381 places, and Croxley Green is one of them.

Work in WD3 and WD18 follows the same survey, fixed quote and written report as everywhere else we cover. That includes premises on New Road, Harvey Road and Bateman Road and the roads around them. If your site is just outside Croxley Green, we cover Holywell (1 mile east), Rickmansworth (1 mile south-west), Batchworth (1 mile south-west), Chorleywood West (2 miles west) and Moor Park (2 miles south).

For rail, the closest station is Rickmansworth station, about 1.3 miles west of the centre.

Why it’s worth doing now in Croxley Green
Every week without a clean adds another layer. BESA guidance says the mean should not go above 200 microns between cleans, and anywhere reaching 500 microns or more needs a spot clean straight away. Heavy build-up takes longer to remove than regular cleans. If the system at a site near Croxley Green fails, there may be nowhere nearby to move to.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

What we do, step by step
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes as long as the system needs, from a few hours to several planned visits, and we clear up before we go. Somewhere like Croxley Green, lanes, gates and parking are worth mentioning in advance.
- First the diagnosis: a survey of the whole system and its access points.
- Grease readings set the baseline, and a fixed quote follows.
- We arrive after close, protect the area and contain the waste.
- Heavy deposits are scraped by hand and the system degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
Before we arrive
- Agree a time when the area can be out of use
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
