Hertfordshire · Canopy and hood cleaning
Allen's Green canopy cleaning
Deep cleaning of kitchen canopies, hoods, plenums and grease filters, inside and out for commercial sites in Allen's Green and across Hertfordshire. CHAS, SafeContractor and ISO 9001, and fully insured.
- Canopy gutters full of old fat
- A plenum thick with grease behind the filters
- A sticky, discoloured canopy
Why act early in Allen's Green
A canopy clean in Allen's Green now stops the grease spreading further. It takes a few hours for most canopies, out of hours so service carries on. Put off, the grease simply moves further into the system. Somewhere as small as Allen's Green, losing a kitchen or building to a fault is felt by everyone who uses it.
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and why the quote is fixed before work begins.

Canopy cleaning in Allen's Green, done properly
We clean canopies in Allen's Green when the kitchen isn’t cooking: after service, overnight or at the weekend. The equipment underneath is switched off, left to cool and sheeted, and the kitchen is left ready for the next service. We’re often asked to deal with smoke hanging around the canopy during service and a hood coated in old grease, across plenum chambers, wall canopies and baffle filters.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
A written report with photos follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Grease, kitchens and Allen's Green
The Food Standards Agency lists about 3 pubs, bars and clubs as registered food businesses within about 1.5 miles of central Allen's Green. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. The fire and rescue service for Allen's Green is Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Kitchens in Allen's Green get their food hygiene inspections from East Hertfordshire 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.
Where a hall near Former Church of St Anne, or anywhere in Allen's Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does. A hospital like Herts and Essex Hospital, about 3.4 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

When to call us in Allen's Green
Moisture in the air mixes with the grease on the canopy. As the canopy cools, condensation forms and runs with the grease. The result is sticky streaks and drips onto the range.
Look out for any of the following:
- A greasy hood noticed by an inspector
- Condensation running down the canopy
- Poor capture at the hood
- Canopy gutters full of old fat
If your kitchen is in a listed or historic building, like the houses around Allen's Green (Much Hadham Palace is about 2.2 miles north-west), fitting access panels needs care.
What to look for in a quote

- Which accreditations they hold, and whether you can check them
- What records you’ll receive afterwards
What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

What else we do in Allen's Green
Common questions in Allen's Green
Can you come to Allen's Green after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
Which council inspects kitchens in Allen's Green?
The local authority for Allen's Green is East Hertfordshire council, and its environmental health team does the inspecting. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Does a canopy clean meet TR19?
TR19® Grease is about the whole extract, from canopy to discharge. Cleaning the canopy alone leaves the ducts, risers and fan untouched, and the report will say what was covered.
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.
How long will it take to clean the canopy?
That depends on the size of the canopy and how much grease is on it. Typically it takes an hour or two for one small canopy, longer where there are several.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
The process
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes a few hours, depending on the size of the canopy and how much grease has built up, and the area is cleaned down before we leave. Pictures of the system and its access let us plan the work in Allen's Green before we set off.
- The canopy is checked from pictures or on a visit.
- 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.
- We put the filters back, tidy up and photograph the finished canopy.
Preparing for the visit
- Clear the space around the work
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Getting a quote does not take long. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Related advice
When something else is needed
Canopy cleaning can’t fix everything, and we’ll tell you before work begins. It does not solve:
- Grease filters too damaged to refit (they need replacing)
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
- A fan that cannot pull enough air because it’s worn out
If you’re not sure, just call 0345 646 2711 or drop us a line and we’ll give you a straight answer before you book.
What the work covers
- Wall canopies

Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site around the people who use them.
Fixed quotes for canopy cleaning in Allen's Green
Some jobs are bigger than they look, and some smaller. The main factors:
- Where the site is and how we reach it
- One-off work versus a regular cycle
- The size of the system
- The condition we find in the survey
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.
