Canopy cleaning in St John's

How it works

Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and leave you the report. The visit itself takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. For a place like St John's, we load the van from the survey notes so the work can be done in one visit where possible.

  1. We look at the canopy, filters and troughs first.
  2. Out of hours, the range is switched off, cooled and covered.
  3. We lift out the filters and scrape the plenum and housing.
  4. Inside and out, the hood and its troughs are cleaned.
  5. Filters are refitted, the area cleaned down and the photo report put together.

Getting ready for the visit

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Let us know about permits to work or site inductions
  • Dig out any earlier paperwork for the system

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Canopy cleaning in St John's, done properly

Every TR19® Grease clean includes the canopy, but some sites need the canopy done between full cleans. Where that is the case, we will be clear that the ducts and fan aren’t included, so your records stay accurate. We are often asked to deal with a hood coated in old grease and condensation and grease dripping together, on canopy light fittings, wall canopies and plenum chambers.

In a smaller place like St John's, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.

Each visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What staff can safely do

Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Do you need canopy cleaning in St John's?

Air straight off the range hits the canopy first. Grease from the vapour lands on the canopy’s inner surfaces, its joints and its filters, and the plenum behind them collects the rest.

These are the problems we see most often:

  • Filters that clog soon after cleaning
  • Wet, greasy drips from the hood
  • Poor capture at the hood
  • A hood coated in old grease

Church and community hall kitchens, near St John's Church or anywhere around St John's, are easy to forget, but their extracts collect grease like any other.

Questions to ask before booking

Common questions in St John's

Do you clean school canteen extracts around St John's out of term?

Yes, out-of-term visits are normal for schools. There are about 11 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of St John's. Booking early in the term gives the best choice of holiday dates.

Who would carry out a food hygiene inspection at a kitchen in St John's?

The local authority for St John's is Woking council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

What if parts of the system can’t be reached?

They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.

What kinds of canopies do you clean?

Canopies in pubs, restaurants, hotels, schools, care homes, offices and other kitchens. Whatever is cooked under it, the canopy is cleaned the same thorough way, with the equipment off and cool.

Do you work in St John's?

Yes. Our area takes in London and the counties of South East England, St John's included.

Do you clean the grease filters as part of a canopy clean?

We remove the filters to reach the plenum, then clean and refit them. Any that are damaged are noted on the report.

How much notice do you need?

It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.

How long will it take to clean the canopy?

A single canopy with a light build-up is fairly quick, but large or heavily soiled canopies take longer. We will tell you what to expect.

Part by part

Wall canopies

Wall canopies sit against a wall over a cooking line. Grease often collects where the canopy meets the wall, and we clean that join along with the inside of the hood.

Plenums and filter housings

Behind the grease filters is the plenum. Grease that slips past the filters settles there, so it’s scraped and degreased on every canopy clean.

Honest limits

We’d rather tell you now than book work that will not help, so here are the limits:

  • Poor airflow from a fan that needs repair
  • Faulty canopy lights or wiring (a job for an electrician)
  • A canopy undersized for the equipment

If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think.

What the work covers

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

Canopy cleaning in St John's: the local picture

Food Standards Agency data counts about 34 cafés, restaurants and staff canteens and about 19 takeaways across St John's and its immediate surroundings (about a mile and a half). Any of those kitchens with a canopy has a hood that needs cleaning inside and out. The fire and rescue service for St John's is Surrey Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Environmental health officers from Woking council inspect food businesses in St John's. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand.

Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to St John's is Brookwood Hospital, about 1 mile west. Term dates shape school work: for a school like The Winston Churchill School A Specialist Sports College, an extract clean fits neatly into a half-term or summer break.

Why deal with it now?

Fresh grease comes off far more easily than old. Over months, the heat hardens it into a stubborn coating, which makes a later clean slower and harder. A site near St John's that has to close at short notice is hard to cover for.

The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before any work starts.

Between visits

Think of this as the after-treatment advice, in brief:

  • Check and empty canopy gutters regularly
  • Avoid harsh scourers that scratch the canopy
  • Leave the extract running until cooking stops
  • Never run the range with a filter out

A full system clean comes with a TR19 certificate from the BESCA Vent Hygiene Elite portal. If the job covers only the canopy, the paperwork reflects that.

The best thing a kitchen can do for its canopy is keep the filters clean. Keep them on a regular cleaning or exchange cycle, and never cook with one missing. Less grease gets into the plenum as a result.
