Canopy Cleaning in Middle Assendon
Canopy cleaning for Middle Assendon, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Heavy deposits behind the grease filters
- Greasy streaks across the canopy
- Condensation running down the canopy
Keeping the system healthy
After the visit, a few habits help the work last:
- Empty the grease troughs before they fill
- Check all filters are fitted before service
- Avoid harsh scourers that scratch the canopy
- Wipe the canopy down at close every day
Anything worth knowing goes into the report: bent or poorly fitting filters, a light cover that is cracked, or troughs that fill too quickly. We keep it to what matters.
Tell us if the canopy starts dripping or the filters clog sooner than usual. It can mean the cooking has changed or the interval is too long, which a grease thickness test can confirm.
Canopy cleaning in Middle Assendon, done properly
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. The work covers wall canopies, plenum chambers and grease gutters, and the jobs we see most are grease dripping from the canopy edge and wet, greasy drips from the hood.
Somewhere as small as Middle Assendon, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What happens on the day
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a few hours, depending on the size of the canopy and how much grease has built up. We agree a date with you, plan the drive to Middle Assendon and turn up when the site is quiet.
- We start by checking the canopy and what’s behind its filters.
- We protect everything below once it has cooled.
- Heavy deposits come off by hand, then the surfaces are degreased.
- We finish the plenum, troughs and canopy and check them over.
- You get photos of the result and a recommended date for the next clean.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Move anything stored near the system
- Let us know about permits to work or site inductions
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Canopy cleaning in Middle Assendon: the local picture
Oxfordshire Fire and Rescue Service covers Middle Assendon. 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. Middle Assendon, about 36 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you.
A hall kitchen that only cooks for events, whether near Church of St James or elsewhere in Middle Assendon, still needs its extract cleaned, just less often. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Greys Court is about 1.8 miles south-west), access may need planning.

What a clean will not put right
Before you book, it helps to know what’s not included:
- Filters that no longer seal in the housing
- A light fitting that does not work
- A hood that doesn’t cover the cooking line
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we will tell you honestly.

Why deal with it now?
In Middle Assendon, as elsewhere, a greasy canopy is one of the first things an inspector sees. Keeping it clean shows the rest of the kitchen is being looked after and keeping it that way is easier than catching up. Out of sight is the usual reason a rural system goes too long without attention.
The cost depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.

Part by part
Plenums and filter housings
Behind the grease filters is the plenum. It catches whatever gets past the filters, so it’s scraped and degreased on every canopy clean.
Grease troughs and gutters
Some troughs drain to a cup or drawer, that is emptied and cleaned too, and we will show staff where it is.

Questions from Middle Assendon
Can you get to a site in Middle Assendon?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Can the work in Middle Assendon be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Middle Assendon can fit around your hours. When you ring 0345 646 2711, or email photos, mention when the site is quiet.
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.
Who is the responsible person?
In the words of the Fire Safety Order 2005, it’s the responsible person. That’s generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.
Do you have a 24/7 line?
Yes. 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.
Is the inside of the hood cleaned?
Inside and out, along with its seams and grease channels. With the filters out, the plenum and housing are cleaned as well.
What happens to the filters during the clean?
They’re taken out, cleaned and refitted. Each filter is checked for fit as it goes back, because gaps let grease through.
Are you insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
What affects the quote in Middle Assendon
We quote each job individually. These are the things that affect it:
- The number of sites or systems
- The condition we find in the survey
- Site rules, permits and inductions
- Travel, parking and unloading
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- Your opening hours and when the area is out of use
- A few general shots of the system
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
