Hertfordshire · Canopy and hood cleaning
Canopy and hood cleaning in Aldenham, Hertfordshire
Canopy cleaning in Aldenham from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Greasy streaks across the canopy
- Filters that clog soon after cleaning
- Condensation and grease dripping together
Why deal with it now?
Drips from a dirty canopy land on the cooking line. It’s a food hygiene concern as much as a fire concern, and EHOs look at the cleanliness of the premises and equipment. In a small place like Aldenham, a system that fails can take a site out of use.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Why Aldenham businesses choose us
- We diagnose before we treat
- A single point of contact for sites across the South East and London
- Accredited under CHAS and SafeContractor, with ISO 9001
- Fully insured

How we handle canopy cleaning in Aldenham
Every TR19® Grease clean includes the canopy, but a canopy can also need cleaning on its own, between full system cleans. Where that is the case, we’ll be clear that the ducts and fan are not included, so your records stay accurate. If you are dealing with poor capture at the hood and a sticky, discoloured canopy, we can put it right.
In a village or hamlet like Aldenham, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Questions from Aldenham
Which environmental health team covers Aldenham?
Kitchens in Aldenham are inspected by Hertsmere council’s environmental health officers. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Is Aldenham within the area you cover?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
What information do you need?
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 0345 646 2711, or email photos.
Where does the waste go?
We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
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.
Why does grease run off the canopy edge?
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. A canopy clean sorts it out.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Different parts, different methods
School and staff canteen kitchens
Canteens and school kitchens tend to run to a timetable, so the canopy can be cleaned when the kitchen is closed. Holidays and weekends work well.
Island canopies
Everything about an island canopy is on show so a clean, even finish matters. It’s degreased and photographed for your report.
Managing agents and facilities teams in Aldenham
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Do you need canopy cleaning in Aldenham?
The plenum is hidden behind the filters, so nobody sees it build up. Daily cleaning reaches the canopy face but rarely gets further, leaving the plenum and housing to collect grease between professional cleans.
If you notice any of these, it’s worth a diagnosis:
- Poor capture at the hood
- Canopy gutters full of old fat
- Filters that clog soon after cleaning
- A hood coated in old grease
For schools such as Fair Field Junior School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.
What your quote should include
- Proof of insurance
- How areas they can’t reach will be recorded
- If the quote is a fixed price or an estimate
- When they can work, and whether that’s outside your opening hours
The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, and that takes a few hours for most canopies. Somewhere as small as Aldenham, the date and timings are agreed with you well before the day.
- We look at the canopy first, from photos or on a visit.
- Cooking equipment is left to cool and the area under the canopy protected.
- Filters come out and the plenum behind them is scraped and degreased.
- Inside and out, the canopy and its grease channels are degreased.
- We refit the filters, clear up and photograph the finished canopy.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.

What canopy cleaning cannot fix
Not every problem is solved by canopy cleaning, and we will tell you before any work starts. It will not put right:
- A hood that does not cover the cooking line
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
- Poor airflow from a fan that needs repair
Not sure which it is? You can call us on 0345 646 2711 or send us an email and we’ll tell you honestly.

Canopy cleaning in Aldenham: the local picture
The FSA’s food hygiene register shows about 17 restaurants, cafés and canteens and about 5 takeaways and sandwich shops across Aldenham and its immediate surroundings (about a mile and a half). Every kitchen among them that cooks under a canopy has a hood, plenum and filters collecting grease. Hertfordshire Fire and Rescue Service covers Aldenham. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Environmental health officers from Hertsmere council inspect food businesses in Aldenham. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
Healthcare kitchens, like those at hospitals such as Watford General Hospital (about 2.8 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (High Elms Manor is about 2.5 miles north-west), access may need planning.
