Canopy cleaning in Chaulden
Duct Doctor has cleaned canopies and hoods since 2009. As a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, we treat the canopy as one part of a whole system, and we are fully insured, with CHAS, SafeContractor and ISO 9001. If you’re dealing with a filter housing caked in grease and a canopy that no longer draws the smoke away, we can put it right, from plenum chambers, canopy light fittings and grease gutters onwards.
Kitchens around a place like Chaulden are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Between visits
Aftercare is simple, and it makes the next visit easier:
- Empty the grease troughs before they fill
- Flag any change in how the canopy behaves
- Don’t scrape the canopy with metal tools
- Clean the hood’s outer surfaces daily
We clear away the sheeting, waste grease and water before we leave. Filters are back in place and seated properly ready for the next service.
Do not let canopy gutters fill to the brim. Overflowing troughs are the usual cause of drips onto the range, so make emptying them part of the closing routine.
When it’s something else
A few issues sit outside what this work can do:
- A light fitting that does not work
- A canopy undersized for the equipment
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
If in doubt, phone us on 0345 646 2711 or send us an email and we’ll say what we think.

What else we do in Chaulden
How the job changes from site to site
Plenums and filter housings
The plenum is the space behind the filters where air gathers before entering the duct. Grease that slips past the filters settles there, so it’s scraped and degreased on every canopy clean.
Island canopies
Island canopies hang over cooking in the middle of the kitchen, which means grease settles on all four sides. We clean all of them, inside and out.
Why it’s worth doing now in Chaulden
A greasy canopy is fuel directly above the flame. A flare-up can catch it and be drawn into the plenum and duct, where a fire is much harder to stop. Cleaning it removes that fuel. It’s easy to lose track of when the work was last done on a quieter site.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

Common questions in Chaulden
Can you get to a site in Chaulden?
Yes. Villages and rural sites across the South East are part of our work, Chaulden included. Photos of the system and directions to the site help us plan the visit.
Which fire authority looks after Chaulden?
Fire safety enforcement in Chaulden 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.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
How much of the canopy do you clean?
Everything from the outer face to the plenum behind the filters. Grease troughs and filter channels are emptied and degreased as part of the job.
What does canopy cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we’ll usually reply within one working day.
Are you insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do we need to close while you work?
Not normally. We need the work area to ourselves while we’re on site, so we book a time when it would be closed anyway.
Do you need canopy cleaning in Chaulden?
A canopy in Chaulden picks up grease at much the same rate as one anywhere else with the same cooking: it comes down to how long the kitchen cooks and what’s on the menu. High-heat cooking coats it fastest.
Look out for these warning signs:
- A greasy hood noticed by an inspector
- Overflowing grease troughs and gutters
- A plenum thick with grease behind the filters
- Smoke hanging around the canopy during service
School kitchens, at schools like Chaulden Junior School for example, are usually cleaned in the holidays so no lunches are lost.
Questions to ask before you book
- If they look at the system before pricing
- What insurance they carry
- When the next visit should be, and why
- What happens if part of the system can’t be accessed
The process
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. Getting to the system matters more than parking in a place like Chaulden, so let us know how to reach it.
- We start by checking the canopy and what’s behind its filters.
- We protect everything below once it has cooled.
- Thick grease is scraped away before the canopy is degreased.
- Plenum, housing, troughs and canopy are all cleaned and checked.
- The canopy is signed off with before and after photos and a next clean date.
Before we arrive
- Agree a time when the area can be out of use
- Make sure someone can let us in and lock up afterwards
- Let us know about parking and loading

What canopy cleaning looks like in Chaulden
The FSA’s data shows about 23 pubs and bars registered across Chaulden and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. It’s Dacorum council that sends environmental health officers to food businesses in Chaulden. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for Chaulden is Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
A kitchen near Hemel Hempstead station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. Healthcare kitchens, like those at hospitals such as Hemel Hempstead Hospital (about 1.4 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.
Chaulden is about 2 miles west of Hemel Hempstead, in Hertfordshire. Chaulden gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with photos. Chaulden is one of 381 towns, villages and districts in Hertfordshire where we work for canopy cleaning. Milton Keynes is in our area too, around 23 miles away.
Work in HP1 and HP3 is surveyed, quoted and booked the same way as anywhere else. Canopy cleaning is available to premises on Furze Road, London Road and Sundew Road and the roads around them. Chaulden sits on or near the A41, which makes travel easy for canopy cleaning. Close by, we work in Bourne End (1 mile west), Fields End (1 mile north-west), Potten End (2 miles north-west), Frithsden (2 miles north-west) and Bulstrode (2 miles south). Further out, we also cover Watford (7 miles south-east), St Albans (7 miles east), Welwyn Garden City (14 miles east), Harpenden (8 miles north-east), Hatfield (12 miles east) and Borehamwood (12 miles south-east).
