Holwellbury ductwork cleaning
Looking for ductwork cleaning in Holwellbury? We survey first, give you a fixed quote and work around your opening hours, finishing with a written report and pictures.
- High readings at a recent grease test
- Years of grease along the duct floor
- Sections of duct with no access panels
The process
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes a few hours for a short run, longer for long runs and tall risers. We agree a date with you, plan the drive to Holwellbury and turn up when the site is quiet.
- First the duct route is traced and every access point noted.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Post-clean readings and photos go into the report, with any unreachable section listed.
Before we arrive
- Move anything stored near the system
- Let us know about parking and loading
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, call 0345 646 2711, or send details by email.

Ductwork cleaning in Holwellbury, done properly
Ductwork in Holwellbury is cleaned the same thorough way as everywhere else we work: we test the grease first, remove thick deposits by hand and degrease what’s left. Post-clean readings and photos complete the record. We’re often asked to deal with duct runs with no cleaning record and years of grease along the duct floor, on horizontal duct runs, multi-storey ducts and attenuators.
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 pictures follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Grease, kitchens and Holwellbury
Look up Holwellbury on the FSA’s food hygiene register and you’ll find about 3 restaurants, cafés and works canteens and about 8 sandwich bars and takeaways within 1.5 miles or so of the middle of Holwellbury. Where they cook under a canopy, grease doesn’t stop at the filters: it settles along the duct and up the riser. Holwellbury sits within the area of 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. Environmental health officers from Central Bedfordshire council inspect food businesses in Holwellbury. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
Bursars and site managers at schools such as Derwent Lower School tend to book extract cleaning for when the kitchen is empty. Where a hall near Church of St Peter (C of E) at Corner with Holwell Road, or anywhere in Holwellbury, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What affects the quote in Holwellbury
The price is fixed before any work begins. It takes into account:
- Where the site is and how we reach it
- The scale of the work
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
What we need to know
When you contact us, it’s useful to have:
- Any previous report or certificate
- Detail shots of panels, filters and grilles
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
For a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You’ll usually have a quote within one working day.
When to call us in Holwellbury
Air cools as it moves away from the canopy. As it cools, the grease it carries condenses onto the duct walls, which is why ducts go on gathering grease well beyond the filters.
It’s time to book a visit if you see:
- Gaps where access panels were never fitted
- Readings above 200 microns from a grease thickness test
- A duct clean needed for an insurer
- Heavy grease at the base of a riser
Healthcare kitchens, like those at hospitals such as Fairfield Hospital (about 2.1 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.
Questions to ask before booking
- Whether the figure could change on the day
- What paperwork you get at the end
- Whether they recommend a next date
- If they look at the system before pricing
Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Tell us if grease leaks from the ductwork
- Get panels fitted where the duct couldn’t be cleaned
- Keep your cleaning records together
- Make sure filters are seated properly
File the paperwork in the maintenance log. An insurer, fire officer or EHO may ask to see it, and the photos make the duct’s condition easy to see.
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.
Common questions in Holwellbury
Can the work in Holwellbury be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in Holwellbury keeps running as normal. Just call 0345 646 2711, or send details by email with your opening times and we will plan around them.
Do you work in villages like Holwellbury?
Yes. Villages and rural sites across the South East are part of our work, Holwellbury included. Just mention lanes, gates or anything else about the site when you book.
Will we have to shut during the visit?
Not usually. We need the work area to ourselves while we’re on site, so we book a time when it would be closed anyway.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.
What if parts of the system can’t be reached?
Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
Do you survey before quoting?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Is a quote from photos possible?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
How the job changes from site to site
Vertical risers
Risers carry the extract up through the building to the roof. Grease runs down the walls and gathers at the base, which is one of the points we test.
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, so each section is cleaned through its access panels.
In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
