Canopy cleaning in Gadebridge, done properly
We have been cleaning kitchen canopies since we started trading in 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’re fully insured, with CHAS, SafeContractor and ISO 9001. The work covers wall canopies, baffle filters and grease gutters, and the jobs we see most are condensation and grease dripping together and canopy gutters full of old fat.
Around a smaller place like Gadebridge, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

FAQs for Gadebridge
Can a school canteen extract in Gadebridge be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Around Gadebridge, the Food Standards Agency lists about 20 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you come to Gadebridge after we close?
Yes, evening, overnight and weekend work is normal for us. That way a site in Gadebridge doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
How much of the canopy do you clean?
Inside and out, along with its seams and grease channels. With the filters out, the plenum and housing are cleaned as well.
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. We will tell you if any need replacing.
Is TR19 a legal requirement?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
How the visit 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 it goes on the report too. The visit takes an hour or two for one small canopy, longer where there are several. Visits to a place like Gadebridge are planned ahead, so we arrive with what the survey says the job needs.
- We look at the canopy, filters and troughs first.
- Out of hours, the range is switched off, cooled and covered.
- We lift out the filters and scrape the plenum and housing.
- Inside and out, the hood and its troughs are cleaned.
- Filters are refitted, the area cleaned down and the photo report put together.
Before we arrive
- Mention any sign-in, permit or induction we need
- Name a contact who can let us in at the agreed time
- Let us know about parking and loading
Get a fixed quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, phone us on 0345 646 2711, or email photos.

Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Tell us when the canopy starts to drip
- Do not scrape the canopy with metal tools
- Keep filters on a set cleaning routine
- Run the extract the whole time you’re cooking
A before and after photo report follows the clean. The report lists what was cleaned and any part we couldn’t get to, so the record is honest and complete.
A daily wipe of the hood keeps fresh grease from baking on. It won’t replace a professional clean, but it slows the build-up you can see.

What happens if it’s left?
Leaving the canopy until the next full clean can mean months of build-up. Some kitchens need the canopy cleaning more often than the whole system, and readings or a look behind the filters will show it. Even a site near Gadebridge that is only busy part of the week needs its system checked on a schedule.
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.

Signs you need canopy cleaning in Gadebridge
Air straight off the range hits the canopy first. Fat in that air settles on the inside of the hood, in its seams and on the filters, and the plenum behind them collects the rest.
What we are most often called out for:
- Grease channels that no longer drain
- A sticky, discoloured canopy
- Wet, greasy drips from the hood
- An EHO comment about the canopy
School kitchens, at schools like Galley Hill Primary School and Nursery for example, are typically cleaned in the holidays so no lunches are lost.

Managing agents and facilities teams in Gadebridge
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 can quote for the whole system.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Gadebridge kitchens: local notes
According to Food Standards Agency records, there are about 27 bars, pubs and nightclubs and about 3 hotels and guest houses within about 1.5 miles of central Gadebridge. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Hertfordshire Fire and Rescue Service covers Gadebridge. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Gadebridge, food businesses are inspected by environmental health officers from Dacorum council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked.
Healthcare kitchens, like those at hospitals such as Hemel Hempstead Hospital (about 1.2 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands. A hall kitchen that only cooks for events, whether near St Alban's Church or elsewhere in Gadebridge, still needs its extract cleaned, just less often.
Gadebridge is about 1 mile north-west of Hemel Hempstead, in Hertfordshire. Gadebridge gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with pictures. Gadebridge is one of 381 places in Hertfordshire we cover for canopy cleaning. For sites nearby, see our Milton Keynes page (22 miles or so).
Canopy cleaning in HP1 and HP2 is surveyed, quoted and booked the same way as anywhere else.

The countryside around Gadebridge includes Long Deans.
What a clean will not put right
It’s worth knowing the limits before booking:
- Poor airflow from a fan that needs repair
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
- A canopy undersized for the equipment
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think.

Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
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. Cleaning inside ducts and units is specialist work.
