About our ductwork cleaning in Garston
We’ve been trading since 2009, working across London and the South East. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with each certificate issued through the BESCA portal. We are often asked to deal with stale grease odours from the duct and grease pooling at the foot of the riser, across access panels, bends and junctions and horizontal duct runs.
Size doesn’t change the work: a kitchen in a place like Garston gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
Good records are part of the job. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Don’t switch the extract off early
- Store the certificate with the fire risk assessment
- Consider fitting panels where the report shows gaps
- Report any grease dripping from duct joints
Access panels are closed and sealed back up after cleaning, and the surrounding area is left clean. Grease and dirty water are contained and removed.
Book the next duct clean before the date passes. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
Questions from Garston
Who inspects food businesses in Garston?
That is Watford council, whose environmental health officers carry out food hygiene inspections in Garston. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can a school canteen extract in Garston be done out of term time?
Yes. The holidays are the usual time for school work. There are about 20 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Garston. Just phone us on 0345 646 2711, or send details by email with your term dates and we will plan around them.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and we normally come back within one working day. Some sites still need a visit, and we’ll say so.
How do you know if the ductwork needs cleaning?
The date on the last certificate is the first thing to check. If it’s overdue, or there isn’t one, a clean is due, and grease readings will confirm how urgent it is.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How do you clean inside the ductwork?
After a survey and grease readings, the duct is opened up through its access panels. We clean the runs and risers section by section, and test again when we’re done.
How do you protect the area?
Floors and surfaces near the work are sheeted before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Common problems we fix in Garston
Damaged or poorly fitted filters let more grease into the duct. More grease reaches the ductwork than it should, and build-up speeds up.
It’s time to book a visit if you see:
- Gaps where access panels were never fitted
- Ductwork that has never been cleaned
- Proof of duct cleaning for the insurer
- Hardened, baked-on grease in long horizontal runs
School kitchens, at schools like The Grove Academy for example, are typically cleaned in the holidays so no lunches are lost.

What the work involves, part by part
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We clean it from the canopy side or through a nearby panel.
Horizontal duct runs
Flat runs of duct link the canopy to the riser or the outside wall. They collect grease as the air cools and slows, and we clean them section by section through access panels.
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes anything from a few hours to several visits, depending on the length of duct. Around Garston, access is normally simpler than in a town centre, though gates and roof access are worth mentioning.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Heavy deposits come out by hand, then each section is degreased.
- We close up, re-test, photograph and record anything out of reach.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions
- Have your last certificate or report to hand
How to get a quote
We don’t publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711, or send details by email.

What affects the cost of ductwork cleaning
The price is fixed before any work begins. It takes into account:
- Travel, parking and unloading
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
- The size of the system
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
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 we can price many jobs without a visit.
Kitchen extracts in Garston
The FSA’s food hygiene register shows about 50 cafés, restaurants and staff canteens and about 18 takeaways in Garston and the streets around it, up to about 1.5 miles out. The duct above a busy canopy coats itself in grease long before anyone sees it. In Garston, food businesses are inspected by environmental health officers from Watford council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. The fire and rescue service for Garston 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.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Garston is Leavesden Hospital, about 1.4 miles north-west. A hall kitchen that only cooks for events, whether near Stanborough Park Church or elsewhere in Garston, still needs its extract cleaned, just less often.

Around Garston
Typical jobs here are in premises near Francis Combe Academy and Garston Park. There’s a railway station in Garston itself: Garston station. Nearby you’ll also find Leavesden Hospital (1.4 miles north-west) and Charter Place (2.3 miles south). For a walk, there’s Longspring Wood and Verulamium Lake.
Why act early in Garston
Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. Anywhere that reaches 500 microns or more needs immediate spot cleaning. Putting off the clean only pushes readings higher. A site near Garston that has to close at short notice is hard to cover for.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
