Canopy cleaning for kitchens and businesses in Portswood
The canopy is where the extract system breathes in. If it’s coated in grease, everything downstream gets more of it. We start the check-up there, and the cure is a thorough clean of the hood, the plenum and the filter housing. The work covers island canopies, baffle filters and plenum chambers, and common reasons people get in touch are canopy gutters full of old fat and a canopy flagged at an environmental health inspection.
In a smaller place like Portswood, 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. A kitchen that cooks fewer hours still builds up grease, so cleaning is planned around how much it cooks and what the readings show.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What a clean will not put right
Before booking, it helps to know what’s not included:
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
- Weak extraction caused by a failing fan motor
- Faulty canopy lights or wiring (a job for an electrician)
If you are not sure, just phone us on 0345 646 2711 or email us and we will give you a straight answer.
Parts of the system we cover
- Canopy light fittings
- Wall canopies
- Plenum chambers
- Island canopies
- Grease gutters
- Baffle filters
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Keep the fan on through service
- Give the canopy a wipe after service
- Avoid harsh scourers that scratch the canopy
- Clean the baffle filters often
The report gives a recommended next clean date. It reflects how long the kitchen cooks and how much grease we removed, in line with BESA guidance.
Clean filters are the canopy’s first defence. Keep them on a regular cleaning or exchange cycle, and make sure they’re all in place before cooking. Less grease gets into the plenum as a result.
What canopy cleaning looks like in Portswood
Portswood is within about 2 miles of the coast. Corrosion on the fan housing and cowl is worth a look at every clean, alongside the grease. According to Food Standards Agency records, there are about 74 bars, pubs and nightclubs and about 15 hotels, B&Bs and guest houses in Portswood and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Food hygiene inspections in Portswood are the job of Southampton council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready.
Volunteers running a hall kitchen near Highfield Church, or anywhere in Portswood, may not know when the extract was last cleaned, and a grease test settles it. A kitchen near St Denys station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. A hospital like Royal South Hants Hospital, about 0.9 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

What we do, step by step
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 an hour or two for one small canopy, longer where there are several. Evenings, weekends or a closed day all work for a site in a place like Portswood.
- Diagnosis first: we look behind the filters as well as at the hood.
- We protect everything below once it has cooled.
- Heavy deposits come off by hand, then the surfaces are degreased.
- We finish the plenum, troughs and canopy and check them over.
- You get photos of the result and a recommended date for the next clean.
Before we arrive
- Arrange a key holder or contact on site
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet

Part by part
Grease troughs and gutters
Grease channels around the canopy collect what runs down the inside. They’re emptied and cleaned during the job, so they can do their job again.
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.

What else we do in Portswood
Portswood: your questions answered
Is canopy cleaning any different in a coastal place like Portswood?
It can. Salt air reaches Portswood, which is within about 2 miles of the coast, and it speeds up rust. Outdoor metalwork near the sea is worth inspecting at each visit.
Who would carry out a food hygiene inspection at a kitchen in Portswood?
The local authority for Portswood is Southampton council, and its environmental health team does the inspecting. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
What causes grease to drip from the hood?
Full gutters and a heavily coated plenum are the common causes. With nowhere to collect, the grease overflows, and condensation can carry it too. Cleaning the canopy and plenum clears it.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Is Portswood in your area?
Yes. We cover Portswood and the rest of Southampton, within our South East and London area. For a fixed quote, call us on 0345 646 2711 or email us.
What about areas you can’t get to?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
What do you need from me for a quote?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply ring 0345 646 2711 or drop us a line.
Do we need to close while you work?
Usually not. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits so parts stay in use.
What affects the quote in Portswood
The survey tells us what the work involves. We look at:
- How easy every part is to reach
- How big the system is
- Travel, parking and unloading
- What state the system is in
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, give us a ring on 0345 646 2711, or email photos for straight advice and a fixed quote.
Helping us quote
Before you ask for a quote, gather:
- Problems your staff have spotted
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- Photos showing the whole system and its surroundings
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To start, ring 0345 646 2711 or use the quote form.
Why it’s worth doing now in Portswood
Drips from a dirty canopy land on the cooking line. That’s a hygiene problem as well as a fire one, and EHOs look at the cleanliness of the premises and equipment. It’s easy to lose track of when the work was last done on a quieter site.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
