Keeping the system healthy

Aftercare is simple, and it makes the next visit easier:

  • Leave the extract running until cooking stops
  • Report new drips or smells from the canopy
  • Empty the grease troughs before they fill
  • Give the canopy a wipe after service

We clear away the sheeting, waste grease and water before we leave. Filters are back in place and seated properly, and the kitchen is ready to cook.

The best thing a kitchen can do for its canopy is keep the filters clean. Wash or exchange them regularly, and make sure they’re all in place before cooking. Less grease gets into the plenum as a result.

How we handle canopy cleaning in Walter's Ash

Every TR19® Grease clean includes the canopy, but some sites need the canopy done between full cleans. Where that’s the case, we will be clear that the ducts and fan aren’t included, so your records stay accurate. If you’re dealing with a sticky, discoloured canopy and heavy deposits behind the grease filters, we can help.

For a kitchen in or near Walter's Ash, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.

Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Fixed quotes for canopy cleaning in Walter's Ash

The quote reflects the site in front of us. We take into account:

  • How many systems or sites are involved
  • When the work can happen, such as evenings, overnight or weekends
  • Site rules, permits and inductions
  • The condition we find in the survey

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call us on 0345 646 2711 or email us for straight advice and a fixed quote.

Helping us quote

You don’t need the technical terms. Just send:

  • The roof, plant room or outside wall the system runs to
  • Where the site is and what kind of site it is
  • Any access panels or hatches you can see
  • Wide photos of the system and the area around it

Getting a quote does not take long. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Why act early in Walter's Ash

When grease clogs the filters and plenum, the canopy can’t draw air as it should. Smoke and heat hang around the cooking line while the fan strains. A clean canopy and plenum let the extract do its job. Out of sight is the usual reason a rural system goes too long without attention.

No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

Each canopy in those kitchens catches grease on the inside of the hood and behind the filters. In Walter's Ash, food businesses are inspected by environmental health officers from Buckinghamshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Walter's Ash falls to Buckinghamshire 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.

How the visit works

Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Photos of the system and how to reach it help us plan a visit to Walter's Ash.

  1. We look at the canopy first, from photos or on a visit.
  2. Cooking equipment is left to cool and the area under the canopy protected.
  3. With the filters out, the plenum and housing are cleaned back.
  4. We degrease the canopy shell, its seams and the grease troughs.
  5. Clean filters are refitted and before and after photos go into your report.

Before we arrive

  • Move anything stored near the system
  • Let us know about parking and loading
  • Mention any locked doors, roof access or ceiling voids

Questions from Walter's Ash

Can a school canteen extract in Walter's Ash be done out of term time?

Yes, and it’s the easiest time to do it. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Walter's Ash, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711, or email photos, and we’ll fit the work in.

Can you work in Walter's Ash outside opening hours?

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Your opening times are the first thing we ask for.

What causes grease to drip from the hood?

Grease that builds up inside the canopy has to go somewhere. When the gutters fill, it overflows onto the range, often mixed with condensation. Cleaning removes the cause.

Do we lose a day’s trading?

Not normally. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.

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.

Where does the waste go?

It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.

Can one contract cover all our sites?

Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.

Which kinds of sites do you work on?

Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.

What a clean won’t put right

Before booking, it helps to know what’s not included:

  • Filters that no longer seal in the housing
  • Ductwork and fans beyond the canopy (those need a full TR19 clean)
  • Weak extraction caused by a failing fan motor

If you’re not sure, just call us on 0345 646 2711 or send us an email and we will give you a straight answer.

Parts of the system we cover

  • Plenum chambers
  • Baffle filters
  • Canopy light fittings
  • Wall canopies
  • Grease gutters
  • Island canopies

What your team can do, and what needs us

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

What the work involves, part by part

School and staff canteen kitchens

Canteen staff see the canopy, not the duct behind it. The canopy and plenum are both cleaned, so what’s out of sight is dealt with too.

Plenums and filter housings

The plenum is the space behind the filters where air gathers before entering the duct. It catches whatever gets past the filters, so it’s scraped and degreased on every canopy clean.
