Canopy cleaning for kitchens and businesses in Grendon Underwood

Think of the canopy as the mouth of the extract. If it’s coated in grease, everything downstream gets more of it. We start the check-up there, and the treatment is a thorough degrease of the hood, plenum and housing. If you’re dealing with smoke hanging around the canopy during service and filters that clog soon after cleaning, we can put it right, from grease gutters, island canopies and plenum chambers onwards.

For a kitchen in or near Grendon Underwood, 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.

Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Honest limits

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

  • Grease in the duct runs and risers behind the canopy
  • A hood that does not cover the cooking line
  • Poor airflow from a fan that needs repair

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

When to call us in Grendon Underwood

Most canopies have troughs or channels that catch running grease. Left to fill up, they spill over, and grease ends up dripping from the canopy edge.

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

  • Fat running down the front of the hood
  • Canopy gutters full of old fat
  • Condensation and grease dripping together
  • Grease filters blocking between washes

Where a hall near Church of St Leonard, or anywhere in Grendon Underwood, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What your quote should include

  • What hours they’ll be on site
  • Whether a written report and pictures are included
  • What insurance they carry
  • How they set the interval to the next visit

Questions to ask before booking

How the job changes from site to site

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.

Plenums and filter housings

The plenum is the space behind the filters where air gathers before entering the duct. Grease that slips past the filters settles there, so it’s scraped and degreased on every canopy clean.

Looking after it afterwards

Looking after the system between visits is straightforward, and it makes the next visit easier:

  • Keep grease cups and drawers emptied
  • Leave the extract running until cooking stops
  • Wash or exchange the filters on a regular cycle
  • Avoid harsh scourers that scratch the canopy

We point out anything we noticed while the canopy was apart: bent or poorly fitting filters, a light cover that’s cracked, or troughs that fill too quickly. It’s a short list of what to watch, not a sales pitch.

Empty the grease troughs and cups before they fill. Most canopy drips start with a full trough, so make emptying them part of the closing routine.

For landlords and multi-site operators

For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.

What staff can safely do

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. The inside of ducts and units needs a specialist.

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

What happens on the day

Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes a few hours, depending on the size of the canopy and how much grease has built up. Pictures of the system and its access let us plan the work in Grendon Underwood before we set off.

  1. The canopy is checked from pictures or on a visit.
  2. Once the kitchen has closed, the cooking line is cooled and sheeted.
  3. With the filters removed, the plenum and filter channels are cleaned.
  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.

Before we arrive

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Let us know about permits to work or site inductions
  • Allow time for equipment near the work to be turned off and cool down

Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Common questions in Grendon Underwood

It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.

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 for anything urgent, ring our 24/7 emergency line.

Will I get a report after the canopy clean?

A photo report, with before and after pictures of the canopy and plenum. It also gives a recommended date for the next clean.

Which canopies and hoods do you clean?

Most commercial kitchen canopies, from one small hood to a long run of canopies. The survey tells us how best to clean yours, from photos or a visit.

Can you set up regular visits?

Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
