Canopy cleaning across Petersham

About our canopy cleaning in Petersham

Think of the canopy as the mouth of the extract. A dirty canopy passes more grease further into the system. Our diagnosis starts there, and the treatment is a thorough degrease of the hood, plenum and housing. If you have a canopy flagged at an environmental health inspection and poor capture at the hood, we can help.

In London, few kitchens can spare a day to close, so extract cleaning in Petersham is typically done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.

Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

For landlords and multi-site operators

Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building around the people who use them.

We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.

Do you need canopy cleaning in Petersham?

Steam and condensation make canopy grease harder to deal with. As the canopy cools, condensation forms and runs with the grease. Drips onto the cooking line are a common result.

If you notice any of these, it’s worth a diagnosis:

  • Filters that never seem to stay clean
  • Fat running down the front of the hood
  • A hood coated in old grease
  • Wet, greasy drips from the hood

Where a hall near St Peter's Church, or anywhere in Petersham, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Choosing a duct cleaning contractor

When it’s something else

Not every problem is solved by canopy cleaning, and we’d rather say so up front. It doesn’t solve:

  • Filters that no longer seal in the housing
  • A canopy too small for the cooking under it (that’s a design question)
  • Faulty canopy lights or wiring (a job for an electrician)

If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think.

Where we work

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

What happens if it’s left?

If the canopy waits for the next full clean, grease keeps adding up. In a busy kitchen, the canopy and plenum can need attention between TR19 cleans, and readings or a look behind the filters will show it. London sites work long hours, and the longer a job is left, the bigger it gets.

When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.

Looking after it afterwards

How long the results last depends on use and care. We suggest:

  • Keep every filter in place while cooking
  • Keep grease cups and drawers emptied
  • Report new drips or smells from the canopy
  • Clean the baffle filters often

The kitchen is handed back clean, with the sheeting gone and the waste removed. Every filter is refitted and checked ready for the next service.

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.

Questions from Petersham

Who is the fire and rescue service for Petersham?

Petersham is in the area of London Fire Brigade. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.

Do you clean school canteen extracts around Petersham out of term?

Yes, and it’s the easiest time to do it. Around Petersham, the Food Standards Agency lists about 13 schools and colleges with registered kitchens within a mile and a half or so. Just phone us on 0345 646 2711 or email us with your term dates and we will plan around them.

What do you do with what you remove?

We take it away when we go. While we work, it’s kept contained so the area stays clean.

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.

Can you look after several sites?

Yes. You deal with one contact for every site in our area, with visits on a regular schedule.

Do you clean canopies in all kinds of kitchens?

Single hoods, long wall canopies and island canopies alike. The survey tells us how best to clean yours, from pictures or a visit.

Do you offer maintenance contracts?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.

Will I get a report after the canopy clean?

A photo report shows the canopy and plenum before and after. If the canopy is cleaned as part of a full TR19 clean, a TR19 certificate is issued too.

What canopy cleaning looks like in Petersham

There are about 224 restaurants, cafés and canteens and about 21 sandwich bars and takeaways within roughly a mile and a half of the centre of Petersham, according to the Food Standards Agency’s register. Where they cook under a hood, the plenum behind the filters is where grease hides. Fire safety in Petersham falls to London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from Richmond-Upon-Thames council inspect food businesses in Petersham. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.

If you look after a school kitchen, at a school such as The Russell Primary School or anywhere near Petersham, the holidays are the usual time for a TR19® clean. A hospital like South Middlesex Hospital, about 1.7 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

What staff can safely do

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

How it works

A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and leave you the report. On site, the work takes a few hours, depending on the size of the canopy and how much grease has built up. We fit London jobs around the building rather than the other way round, so a visit in Petersham is normally out of hours.

  1. We look at the canopy, filters and troughs first.
  2. Out of hours, the range is switched off, cooled and covered.
  3. With the filters removed, the plenum and filter channels are cleaned.
  4. Inside and out, the hood and its troughs are cleaned.
  5. We put the filters back, tidy up and photograph the finished canopy.

Preparing for the visit

  • Clear loose items from the work area
  • Tell us the best time to work, such as after service or at a weekend
  • Have your last certificate or report to hand
