Ductwork cleaning for kitchens and businesses in Sopwell
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. The work covers attenuators, bends and junctions and multi-storey ducts, and the jobs we see most are gaps where access panels were never fitted and grease leaking from duct joints.
Around a smaller place like Sopwell, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. A kitchen that cooks fewer hours still builds up grease, so cleaning is planned around how much it cooks and what the readings show.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What affects the cost of ductwork cleaning
A fixed price needs a few facts first. We look at:
- The scale of the work
- Working hours and out-of-hours timing
- How many systems or sites are involved
- Site requirements such as sign-in and permits
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711, or email photos for straight advice and a fixed quote.
What we need to know
Before you ask for a quote, gather:
- The site address and the type of premises
- Your last certificate, test record or report
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then send you a fixed quote. To start, give us a ring on 0345 646 2711 or drop us a line.
What happens if it’s left?
TR19® isn’t law, but the duty to manage fire risk is. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. Systems on quieter sites still build up dirt and wear, just more slowly.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.
Why us?
- Every visit written up, with pictures
- Work around your opening hours, with 24/7 emergency cover
- Accredited under CHAS and SafeContractor, with ISO 9001
- One number for every site across the South East and London

How it works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes anything from a few hours to several visits, depending on the length of duct. Around Sopwell, access is normally simpler than in a town centre, though gates and roof access are worth mentioning.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Clear loose items from the work area
- Tell us where we can park and unload

When to call us in Sopwell
Ducts in Sopwell gather grease for the same reasons as ducts anywhere: daily cooking hours, the menu and the state of the filters. Under BESA guidance, the minimum interval is 3, 6 or 12 months, by daily cooking hours.
Signs it’s time to call us include:
- Thick deposits at the bottom of a vertical duct
- High readings at a recent grease test
- Sections of duct with no access panels
- A rancid smell from the extract duct
If you run catering at a healthcare site, such as a hospital like Napsbury Hospital about 1.5 miles south-east, the extract may need cleaning more often than a part-time kitchen.
Questions to ask before booking
- Whether the work can be done while the site is closed
- What paperwork you get at the end
- If they look at the system before pricing
- What’s included in the scope, part by part

Other services in Sopwell
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Between visits
To keep the system working properly between visits:
- Keep your cleaning records together
- Report any grease dripping from duct joints
- Have the grease measured if cooking hours go up
- Don’t block access panels with shelving or stock
Access panels are closed and sealed back up after cleaning, and the surrounding area is left clean. Grease and dirty water are contained and removed.
Keep the fan on throughout service. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
What ductwork cleaning looks like in Sopwell
Food Standards Agency records include about 54 bars, pubs and nightclubs and about 4 hotels and guest houses in and around Sopwell, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Sopwell sits within the area of Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. It’s St Albans City council that sends environmental health officers to food businesses in Sopwell. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready.
If you run a church or community hall kitchen, near St. Julian's Church or elsewhere in Sopwell, its extract still collects grease from every lunch and event. Term dates shape school work: for a school like Mandeville Primary School, an extract clean fits neatly into a half-term or summer break.

Sopwell: your questions answered
Do you do school kitchen extract cleaning in Sopwell in the summer holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 6 schools and colleges with food registrations within roughly a mile and a half of Sopwell. Just phone us on 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Which council inspects kitchens in Sopwell?
In Sopwell, it’s St Albans City council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Will the duct clean disrupt the kitchen?
We clean while the kitchen is closed, so evenings, nights and weekends are all possible. The extract and cooking equipment need to be off.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
What should I send you?
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. Then call us on 0345 646 2711, or send details by email.
Are you fully insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
How the job changes from site to site
Horizontal duct runs
Horizontal runs carry the extract along ceilings and through voids. Grease drops out of the slowing air along them, and we clean them section by section through access panels.
Access panels
Panels have to seal properly once they’re closed so the duct stays tight. We’ll tell you if any panel needs replacing.
