About our canopy cleaning in Sopwell

Grease troughs, seams and the inside edge of the canopy are the spots a daily wipe misses. We scrape the heavy deposits, then degrease the surfaces with methods that suit the build-up, using hot water or steam where it helps. The work covers island canopies, plenum chambers and canopy light fittings, and the jobs we see most are grease channels that no longer drain and grease filters blocking between washes.

Size does not change the work: a kitchen in a place like Sopwell gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.

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.

When it’s something else

Canopy cleaning cannot fix everything, and we’d rather say so up front. It does not solve:

  • Weak extraction caused by a failing fan motor
  • Ductwork and fans beyond the canopy (those need a full TR19 clean)
  • A hood that does not cover the cooking line

Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly before you book.

What we work on in Sopwell

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

What affects the cost of canopy cleaning

We quote each job individually. This is what makes a difference:

  • Where the site is and how we reach it
  • How many systems or sites are involved
  • How easy every part is to reach
  • When the work can happen, such as evenings, overnight or weekends

You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or use the quote form, and we’ll explain what it covers.

What we need to know

A few details help us quote accurately. With your enquiry, please include:

  • Wide pictures of the system and the area around it
  • The site address and the type of premises
  • Any access panels or hatches you can see
  • The paperwork from the last visit, if you have it

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, you get a fixed price before work begins.

Signs you need canopy cleaning in Sopwell

Filters that are missing, damaged or badly seated leave gaps. The plenum and housing behind them then take far more grease than they should, which shows up as heavy deposits when the filters come out.

Clients typically contact us after spotting one of these:

  • Grease channels that no longer drain
  • An EHO comment about the canopy
  • A filter housing caked in grease
  • Wet, greasy drips from the hood

Bursars and site managers at schools such as Mandeville Primary School tend to book extract cleaning for when the kitchen is empty.

Choosing a duct cleaning contractor

Canopy cleaning around Sopwell

There are about 147 restaurants, cafés and canteens and about 41 takeaways within about 1.5 miles of central Sopwell, according to the Food Standards Agency’s register. Where they cook under a hood, the plenum behind the filters is where grease hides. Sopwell sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Sopwell, food businesses are inspected by environmental health officers from St Albans City council. 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.

Healthcare kitchens, like those at hospitals such as Napsbury Hospital (about 1.5 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands. Volunteers running a hall kitchen near St. Julian's Church, or anywhere in Sopwell, may not know when the extract was last cleaned, and a grease test settles it.

Sopwell is about 1 mile south of St Albans, in Hertfordshire. Anywhere in AL1, we cover canopy cleaning for commercial sites. Sopwell is one of 381 towns, villages and districts in Hertfordshire where we work for commercial clients. There’s also a page for London, about 19 miles away.

We cover every part of the AL1, AL2 and AL3 postcode area for canopy cleaning and the roads nearby. Canopy cleaning is available to premises on Nuns Lane, Jenny Lane and Vesta Avenue and nearby roads. If your site is just outside Sopwell, we cover St Stephens (1 mile north-west), St Albans (1 mile north), Park Street (1 mile south), Chiswell Green (1 mile south-west) and Frogmore (1 mile south).

Green spaces nearby include Grebe House Wildlife Garden and Verulamium Lake.

Keeping the system healthy

Once we have finished, these simple steps help:

  • Empty the grease troughs before they fill
  • Do not scrape the canopy with metal tools
  • Wipe the canopy down at close every day
  • Leave the extract running until cooking stops

Keep the photo report with your maintenance log, so it’s ready when an EHO, insurer or fire officer asks. Before and after photos speak for themselves.

Wipe the canopy surfaces at the end of each day. It will not replace a professional clean, but it slows the build-up you can see.

How the visit works

Your staff do not 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. Afterwards, the area is left tidy and the written report follows. Evenings, weekends or a closed day all work for a site in a place like Sopwell.

  1. We start by checking the canopy, filters and plenum.
  2. The range is turned off and allowed to cool before we cover it.
  3. Filters come out and the plenum behind them is scraped and degreased.
  4. Inside and out, the canopy and its grease channels are degreased.
  5. Filters go back, the area is cleaned down and photos are taken.

Getting ready for the visit

  • Let us know about permits to work or site inductions
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Dig out any earlier paperwork for the system

FAQs for Sopwell

Can you clean school kitchen extracts in Sopwell during the holidays?

Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 6 schools, colleges and universities with registered kitchens within about a mile and a half of Sopwell. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Do you work in villages like Sopwell?

Yes. Sopwell is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.

Which accreditations do you hold?

BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we’re fully insured.

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

The filters come out so the plenum behind them can be cleaned, then clean and refit them. We’ll tell you if any need replacing.

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.

Can you look after several sites?

Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.

How long is a canopy clean?

One lightly soiled hood doesn’t take long, while long canopies, several hoods or heavy deposits take more time. You’ll know before we start.

Do you clean canopies in all kinds of kitchens?

Wall canopies, island canopies and single hoods over individual appliances. The method is the same: filters out, plenum and housing cleaned, canopy degreased inside and out.

Landlords, agents and facilities managers

From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

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 are happy to quote for all of it.

What the work involves, part by part

Grease troughs and gutters

A blocked or full trough is the usual cause of grease dripping from the canopy. Cleaning it clears the drip.

School and staff canteen kitchens

A canteen canopy may cook fewer hours, but it still collects grease. BESA guidance still sets a minimum interval for the whole system, and the canopy is part of it.
