How we handle canopy cleaning in Trowley Bottom
Dripping edges and a sticky hood are the first things a visitor notices. What isn’t seen, behind the filters, tends to be worse. We clean both, so the canopy is clean where it shows and where it doesn’t. If you have a plenum thick with grease behind the filters and a greasy hood noticed by an inspector, we can help, from canopy light fittings, island canopies and wall canopies onwards.
In a village or hamlet like Trowley Bottom, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What we are called out for in Trowley Bottom
A canopy in Trowley Bottom 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. Frying and grilling load a canopy far faster than steaming or boiling.
Signs it’s time to call us include:
- Filters that clog soon after cleaning
- Condensation running down the canopy
- Grease channels that no longer drain
- A sticky, discoloured canopy
A hall kitchen that only cooks for events, whether near Church of St Leonard or elsewhere in Trowley Bottom, still needs its extract cleaned, just less often.
Questions to ask before you book
- What records you’ll receive afterwards
- Which accreditations they hold, and whether you can check them
- When they can work, and whether that’s outside your opening hours
- What happens if part of the system cannot be accessed
Your questions about canopy cleaning in Trowley Bottom
Which fire and rescue service is responsible for Trowley Bottom?
Fire safety enforcement in Trowley Bottom is handled by Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can you work in Trowley Bottom outside opening hours?
Yes. We work evenings, overnight and at weekends. It means the site in Trowley Bottom keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
How much does canopy cleaning cost in Trowley Bottom?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before we start.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Is Trowley Bottom in your area?
Yes. We cover Trowley Bottom and across Hertfordshire, as part of our work across South East England and London. To book, phone us on 0345 646 2711, or email photos.
Will I get a report after the canopy clean?
Photos of the canopy and plenum before and after. It also gives a recommended date for the next clean.
How much of the canopy do you clean?
The whole canopy, inside and out. We also remove the filters and clean the plenum and housing behind them because that is often the dirtiest part.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
How we price canopy cleaning
Your quote is based on your site. We take into account:
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
- How big the system is
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before we start.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- A few general shots of the system
- Detail shots of panels, filters and grilles
- The paperwork from the last visit, if you have it
- Problems your staff have spotted
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
What happens if it’s left?
Drips from a dirty canopy land on the cooking line. That’s a hygiene problem as well as a fire one, and environmental health officers look at the cleanliness of equipment, extraction included. Systems in rural buildings are often out of sight and out of mind.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
What you get with us
- CHAS, SafeContractor and ISO 9001
- A written report with photos after every visit
- Ventilation hygiene specialists since 2009
- One number for every site across the South East and London

Part by part
Grease troughs and gutters
Drips from the canopy edge often start in a full gutter. We clean it out so the grease has somewhere to go.
School and staff canteen kitchens
Canteen staff see the canopy, not the duct behind it. We clean it and the plenum behind the filters, so what’s out of sight is dealt with too.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
