Hertfordshire · Canopy and hood cleaning
Sandridge canopy cleaning
For canopy cleaning in Sandridge, one call is all it takes, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- A greasy hood noticed by an inspector
- Smoke hanging around the canopy during service
- Wet, greasy drips from the hood
Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Check and empty canopy gutters regularly
- Report new drips or smells from the canopy
- Use non-abrasive cloths on the hood
- Refit filters the right way round and fully seated
The report gives a recommended next clean date. It reflects how long the kitchen cooks and how much grease we removed, in line with BESA guidance.
Clean filters are the canopy’s first defence. Keep them on a regular cleaning or exchange cycle, and never cook with one missing. Less grease gets into the plenum as a result.
Canopy cleaning in Sandridge
If the canopy in Sandridge is dripping, sticky or overdue a clean? Send us a photo of the hood and filters when you give us a ring on 0345 646 2711 or send us an email, and we’ll send you a fixed quote for canopy cleaning, normally within one working day. We’re often asked to deal with a hood coated in old grease and a canopy flagged at an environmental health inspection, across canopy light fittings, plenum chambers and grease gutters.
Somewhere as small as Sandridge, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Staff cleaning versus specialist work
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, and that’s where we come in.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Canopy cleaning around Sandridge
Look up Sandridge on the FSA’s food hygiene register and you’ll find about 12 restaurants, cafés and works canteens and about 9 takeaways and sandwich shops in Sandridge and the streets around it, up to about 1.5 miles out. Where they cook under a hood, the plenum behind the filters is where grease hides. Sandridge sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Sandridge, food businesses are inspected by environmental health officers from St Albans City council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
A hall kitchen that only cooks for events, whether near St Leonard's Church or elsewhere in Sandridge, still needs its extract cleaned, just less often. A hospital like St Albans City Hospital, about 2.1 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Your questions about canopy cleaning in Sandridge
Can you get to a site in Sandridge?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Can you come to Sandridge after we close?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Sandridge needn’t be disturbed. Just call 0345 646 2711, or email photos with your opening times and we will plan around them.
Which accreditations do you hold?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
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.
How much does canopy cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, normally ready within one working day.
Do we need to close while you work?
Not normally. We need the work area to ourselves while we’re on site, so we book a time when it would be closed anyway.
Does the law say we must follow TR19?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
What happens if it’s left?
Baked-on grease gets harder to shift the longer it stays. Heat from the range bakes canopy grease into a hard, dark layer, so the longer it’s left, the longer the clean takes. Rural sites cannot always move to another kitchen or room when something fails.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.

What else we do in Sandridge
When to call us in Sandridge
Grease does not build up any differently in Sandridge: it comes down to how long the kitchen cooks and what’s on the menu. Frying and grilling load a canopy far faster than steaming or boiling.
What we are most often called out for:
- A canopy that no longer draws the smoke away
- Greasy streaks across the canopy
- Grease channels that no longer drain
- Condensation and grease dripping together
Term dates shape school work: for a school like Sandridge School, an extract clean fits neatly into a half-term or summer break.

- Whether a written report and pictures are included
- How VAT is shown on the quote
- Whether the work can be done while the site is closed
What we do, step by step
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes a few hours, depending on the size of the canopy and how much grease has built up. The timing of a visit to Sandridge is set by you, and the travel is our side of the planning.
- The canopy is checked from pictures or on a visit.
- 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.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Tell us about site rules, permits or sign-in
- Find the previous report, if there is one
How to get a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.

What affects the quote in Sandridge
The diagnosis comes before the price. We look at:
- When the work can happen, such as evenings, overnight or weekends
- The condition of the system
- Parking and loading at the site
- The number of sites or systems
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
What a clean won’t put right
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- Grease filters too damaged to refit (they need replacing)
- Faulty canopy lights or wiring (a job for an electrician)
- Weak extraction caused by a failing fan motor
If you are not sure, just call us on 0345 646 2711, or send details by email and we’ll give you a straight answer.
