About our canopy cleaning in Chorleywood
Canopy cleans are done out of hours: evenings, overnight, early mornings or weekends. Cooking equipment is turned off and cooled, then covered, and the kitchen is left ready for the next service. If you have heavy deposits behind the grease filters and poor capture at the hood, we can put it right.
Size doesn’t change the work: a kitchen in a place like Chorleywood gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

What happens on the day
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes a few hours, depending on the size of the canopy and how much grease has built up. Everything the job in Chorleywood needs is worked out beforehand, from the survey.
- We look at the canopy first, from pictures or on a visit.
- The range is turned off and allowed to cool before we cover it.
- We remove the grease filters and clean the plenum and filter housing.
- Inside and out, the canopy and its grease channels are degreased.
- Clean filters are refitted and before and after photos go into your report.
Getting ready for the visit
- Arrange a key holder or contact on site
- Have your last certificate or report to hand
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Your questions about canopy cleaning in Chorleywood
Will you come out to Chorleywood?
Yes, Chorleywood is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Which fire and rescue service is responsible for Chorleywood?
That is Hertfordshire Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.
Why does grease run off the canopy edge?
Usually because the troughs or gutters are full, or the plenum is overloaded. With nowhere to collect, the grease overflows, and condensation can carry it too. A canopy clean sorts it out.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then give us a ring on 0345 646 2711 or drop us a line.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Grease, kitchens and Chorleywood
Food Standards Agency records list about 32 restaurants, cafés and canteens and about 14 takeaways and sandwich shops within roughly a mile and a half of the centre of Chorleywood. Wherever there’s a canopy over the cooking, its hood and plenum collect grease with every service. In Chorleywood, food businesses are inspected by environmental health officers from Three Rivers council. 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. The fire and rescue service for Chorleywood is Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
A hall kitchen that only cooks for events, whether near Christ Church or elsewhere in Chorleywood, still needs its extract cleaned, just less often. If you run catering at a healthcare site, such as a hospital like Harefield Hospital about 3.2 miles south, the extract may need cleaning more often than a part-time kitchen.
Chorleywood is about 5 miles west of Watford, in Hertfordshire. From the centre of Chorleywood to the outskirts, canopy cleaning is available to all kinds of commercial premises, from a single unit to a large public building. Chorleywood is one of 381 places in Hertfordshire where we work for commercial clients. London is in our area too, around 20 miles away.
We work across WD3 for canopy cleaning and the streets around it. That includes premises on South Cottage Drive, South Cottage Gardens and South Park Avenue and the roads around them. Chorleywood sits on or near the A404, which makes travel easy for canopy cleaning. If your site is just outside Chorleywood, we cover Heronsgate (1 mile south-west), Maple Cross (2 miles south), Chenies (2 miles north-west), Horn Hill (2 miles south-west) and West Hyde (3 miles south). Further out, we also cover Watford (5 miles east), Hemel Hempstead (7 miles north), St Albans (10 miles north-east), Harpenden (13 miles north-east), Hatfield (14 miles north-east) and Borehamwood (10 miles east).

Well-known places in the area include Harefield Hospital (3.2 miles south) and Chiltern Open Air Museum (2 miles south-west). For a walk, there’s Chorleywood Common and Tumbling Bay.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Use non-abrasive cloths on the hood
- Keep the fan on through service
- Keep grease cups and drawers emptied
- Keep every filter in place while cooking
We point out anything we noticed while the canopy was apart: damaged filters, gaps around the housing or troughs that need emptying more often. We keep it to what matters.
Tell us if the canopy starts dripping or the filters clog sooner than usual. More drips or quicker clogging often mean the cleaning interval needs looking at, which a grease thickness test can confirm.
What canopy cleaning cannot fix
We won’t sell you work that does not address the problem, so here are the limits:
- Bent or broken filters
- A hood that does not cover the cooking line
- A light fitting that does not work
Not sure which it is? You can call us on 0345 646 2711, or send details by email and we will tell you honestly.
What the work covers
- Wall canopies
- Plenum chambers
- Island canopies
- Baffle filters
- Canopy light fittings
- Grease gutters
What affects the cost of canopy cleaning
Your quote is based on your site. We take into account:
- The size of the system
- A single visit or a regular plan
- Travel, parking and unloading
- The condition we find in the survey
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Where the site is and what kind of site it is
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.
Common problems we fix in Chorleywood
A canopy with gaps around its filters lets grease straight through. The plenum and housing behind them then take far more grease than they should, which shows up as heavy deposits when the filters come out.
Most sites get in touch when they notice one of these:
- A sticky, discoloured canopy
- Heavy deposits behind the grease filters
- An EHO comment about the canopy
- Overflowing grease troughs and gutters
If you cook for passing trade around Chorleywood station, the extract can be cleaned between your last and first customer.

Managing agents and facilities teams in Chorleywood
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
