Your questions about ductwork cleaning in St Albans
Do you work overnight in St Albans?
Yes. We work evenings, overnight and at weekends. The work in St Albans can fit around your hours. Let us know the hours you are closed and we will book within them.
Which fire and rescue service is responsible for St Albans?
Hertfordshire Fire and Rescue Service is the fire and rescue service for St Albans. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply ring 0345 646 2711, or send details by email.
What shows that the ducts need a clean?
A grease thickness test gives the answer. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. A mean above 200 microns, or 500 microns at any point, means it’s due.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Does the law say we must follow TR19?
Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.
What if part of the duct can’t be reached?
Any section we cannot reach is recorded on the report, as TR19 expects. We can fit new access panels so they’re cleaned next time.
How much does ductwork cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we will typically reply within one working day.
Ductwork cleaning in St Albans, done properly
Not sure when the ductwork was last cleaned? Tell us about the system when you phone us on 0345 646 2711, or send details by email, and a fixed price will follow, normally within one working day. The work covers attenuators, access panels and multi-storey ducts, and people most often call us about proof of duct cleaning for the insurer and grease seeping out of the duct seams.
In the busier parts of St Albans, kitchens are often on the ground floor with flats or offices above, with risers that run up the back of the building to roof level. A riser needs proper access to be cleaned top to bottom, and anything we cannot reach goes on the report.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
What affects the quote in St Albans
You will get a fixed price before work begins. It’s based on:
- Site rules, permits and inductions
- Travel, parking and unloading
- Access, including roofs, risers and ceiling voids
- The scale of the work
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, ring 0345 646 2711, or email photos for straight advice and a fixed quote.
What we need to know
To speed up the quote, send us:
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
For a fixed quote, ring 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We usually come back within one working day.
What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. On site, it takes a few hours for a short run, longer for long runs and tall risers. In St Albans, bigger jobs are often split over several out-of-hours visits.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down

Every quote begins with a look at the system, 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.
Advice
Why act early in St Albans
Dealing with the ductwork in St Albans now beats dealing with it after a problem. It takes from a few hours to more than one visit, depending on duct length and access, done out of hours so the kitchen keeps cooking. Keeping the paperwork current for a site in St Albans is easier than explaining why it isn’t.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.

- Faulty fire dampers
- Parts of the duct with no way in
- Ductwork that was poorly designed
If you’re not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer.

Ductwork cleaning in St Albans: the local picture
Look up St Albans on the FSA’s food hygiene register and you will find about 167 restaurants, cafés and works canteens and about 44 takeaways within about 1.5 miles of central St Albans. Behind every canopy among them is a run of ductwork that collects grease out of sight. St Albans is covered by Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Food hygiene inspections in St Albans are the job of St Albans City council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you run a church or community hall kitchen, near Church of St. Peter or elsewhere in St Albans, its extract still collects grease from every lunch and event. For schools such as Loreto College, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Do you need ductwork cleaning in St Albans?
Slow air leaves the most grease behind. Flat runs, bends, reducers and the base of risers are the usual hotspots, and those are the points we pay most attention to.
These are the problems we see most often:
- Ductwork that has never been cleaned
- Heavy grease at the base of a riser
- Sections of duct with no access panels
- Readings above 200 microns from a grease thickness test
A hospital like St Albans City Hospital, about 0.9 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
What your quote should include
- Whether a survey comes first
- What records you will receive afterwards
- When the next visit should be, and why
- Whether inaccessible sections are listed on the report

What else we do in St Albans
Different parts, different methods
Horizontal duct runs
Long horizontal runs need access panels at regular intervals. Any stretch out of reach is noted and can fit extra panels.
Multi-storey and shared buildings
A duct that climbs several floors may be cleaned over more than one visit. Visits are planned around the building’s hours, out of hours where possible.
