How we handle canopy cleaning in Frithsden
Has the canopy started to drip or look neglected? Send us a photo of the hood and filters when you call 0345 646 2711 or drop us a line, and you will get a fixed price, usually within one working day. We are often asked to deal with poor capture at the hood and filters that never seem to stay clean, across canopy light fittings, island canopies and wall canopies.
In a village or hamlet like Frithsden, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What the work involves, part by part
Island canopies
Island canopies often have filters on two sides. We work round the canopy, cleaning each filter bank and plenum.
School and staff canteen kitchens
School and canteen kitchens often cook to set hours, which makes a canopy clean easy to schedule. Holidays and weekends work well.
When to call us in Frithsden
Moisture in the air mixes with the grease on the canopy. As the canopy cools, condensation forms, carrying grease with it. The result is sticky streaks and drips onto the range.
Clients normally contact us after spotting something like this:
- Overflowing grease troughs and gutters
- Condensation running down the canopy
- Poor capture at the hood
- Drips from the canopy onto the range
School kitchens, at schools like Potten End CofE Primary School for example, are usually cleaned in the holidays so no lunches are lost.
Before booking anyone
- What insurance they carry
- Whether a survey comes first
- If the quote is a fixed price or an estimate
- When they can work, and whether that is outside your opening hours
What affects the quote in Frithsden
A fixed price needs a few facts first. We look at:
- Access, including roofs, risers and ceiling voids
- The times the site is available
- Any permits to work or inductions
- Parking and loading at the site
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, give us a ring on 0345 646 2711 or send us an email for straight advice and a fixed quote.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Any access panels or hatches you can see
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
When it’s something else
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Weak extraction caused by a failing fan motor
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
- A light fitting that doesn’t work
Not sure which it is? You can phone us on 0345 646 2711 or email us and we will tell you honestly.
What the work covers
- Baffle filters
- Island canopies
- Plenum chambers
- Canopy light fittings
- Grease gutters
- Wall canopies
Frithsden questions
Who inspects food businesses in Frithsden?
In Frithsden, it’s Dacorum council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Is Frithsden within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Frithsden included. A survey first, from pictures or a visit, means we arrive with the right kit.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What should I send you?
Some photos and a quick description of the system plus the address and your hours. If we need more, we will ask.
Why is my canopy dripping grease?
Normally because the troughs or gutters are full, or the plenum is overloaded. With nowhere to collect, the grease overflows, and condensation can carry it too. Cleaning the canopy and plenum clears it.
What paperwork do I get after a canopy clean?
A photo report shows the canopy and plenum before and after. Full system cleans also come with a TR19 certificate.
When do you clean the canopy?
We clean out of hours as a matter of course, at night, early in the morning or at weekends. The kitchen is handed back ready to cook.
What does canopy cleaning cost?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.

What we do, step by step
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. For a village or hamlet like Frithsden, tell us about narrow lanes, gates and parking when you book.
- We look at the canopy, filters and troughs first.
- Out of hours, the range is switched off, cooled and covered.
- With the filters removed, the plenum and filter channels are cleaned.
- Inside and out, the hood and its troughs are cleaned.
- We put the filters back, tidy up and photograph the finished canopy.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Move anything stored near the system
- Arrange a key holder or contact on site

Advice
For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
What canopy cleaning looks like in Frithsden
Food Standards Agency records list about 5 restaurants, cafés and canteens in Frithsden and the streets around it, up to about 1.5 miles out. Any of those kitchens with a canopy has a hood that needs cleaning inside and out. The fire and rescue service for Frithsden is 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. Food hygiene inspections in Frithsden are the job of Dacorum council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Volunteers running a hall kitchen near Church of St Lawrence, or anywhere in Frithsden, may not know when the extract was last cleaned, and a grease test settles it. A hospital like Hemel Hempstead Hospital, about 3.1 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
