Canopy cleaning in Aspenden
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 hold CHAS, SafeContractor and ISO 9001. The work covers plenum chambers, baffle filters and wall canopies, and common reasons people get in touch are wet, greasy drips from the hood and a greasy hood noticed by an inspector.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What we do, step by step
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. On site, the work takes a few hours for most canopies. Rural roads and tight entrances are worth telling us about before a visit to Aspenden.
- 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.
- We finish the plenum, troughs and canopy and check them over.
- The canopy is signed off with before and after photos and a next clean date.
Before we arrive
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in
- Name a contact who can let us in at the agreed time

Leave it or put it right?
Grease dripping from the hood can fall onto food, pans and worktops. That is a hygiene problem as well as a fire one, and EHOs look at the cleanliness of the premises and equipment. Equipment tucked in a roof space or outbuilding near Aspenden rarely gets looked at unless someone books it.
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711, or email photos, and we’ll explain what it covers.

Do you need canopy cleaning in Aspenden?
Filters that are missing, damaged or badly seated leave gaps. 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.
Keep an eye out for these warning signs:
- Grease channels that no longer drain
- A greasy hood noticed by an inspector
- Grease filters blocking between washes
- Heavy deposits behind the grease filters
Volunteers running a hall kitchen near Parish Church of St Mary, or anywhere in Aspenden, may not know when the extract was last cleaned, and a grease test settles it.

What else we do in Aspenden
Canopy cleaning in Aspenden: the local picture
The FSA’s data shows about 6 pubs and bars registered across Aspenden 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. The fire and rescue service for Aspenden 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. It’s East Hertfordshire council that sends environmental health officers to food businesses in Aspenden. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Term dates shape school work: for a school like Millfield First and Nursery School, an extract clean fits neatly into a half-term or summer break.

Questions from Aspenden
Do you work in villages like Aspenden?
Yes, we work in villages as well as towns, and Aspenden is covered. Let us know about access, parking and anything unusual about getting there when you book.
Which fire and rescue service is responsible for Aspenden?
Fire safety enforcement in Aspenden 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.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Which canopies and hoods do you clean?
Canopies in pubs, restaurants, hotels, schools, care homes, offices and other kitchens. The routine stays the same whatever the kitchen, with the equipment off and cool.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Do we need to close while you work?
Not normally. The area we are working in has to be out of use while we’re there, so the visit goes in a quiet slot.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Part by part
School and staff canteen kitchens
In a school or workplace canteen, the canopy is often the only part of the extract staff ever see. The canopy and plenum are both cleaned, so what’s out of sight is dealt with too.
Plenums and filter housings
A plenum that hasn’t been cleaned for a long time can hold a thick layer of grease. Heavy deposits are scraped out by hand before degreasing.
Aftercare tips
Here’s the after-treatment advice, in brief:
- Report new drips or smells from the canopy
- Keep filters on a set cleaning routine
- Use non-abrasive cloths on the hood
- Wipe the canopy down at close every day
Where the canopy is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. Where only the canopy is done, the report says so clearly.
Empty the grease troughs and cups before they fill. Overflowing troughs are the usual cause of drips onto the range, so make emptying them part of the closing routine.
Honest limits
Canopy cleaning cannot fix everything, and we will tell you before we start. It doesn’t solve:
- Bent or broken filters
- Weak extraction caused by a failing fan motor
- A dirty extract fan further along the system
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.
