Ventilation duct cleaning in Potters Bar, done properly
In a building in Potters Bar, the people inside spend hours breathing what the ventilation delivers. Keeping the ducts clean is a sensible part of looking after them, as much as clean filters and a well-kept AHU. If you have rooms that feel airless when the system runs and extract ducts clogged with lint and dust, we can help, from supply ductwork, toilet extract systems and offices and schools onwards.
Many schools and offices in a town like Potters Bar have a mix of older and newer ventilation. The work starts with an inspection to decide what needs cleaning, so you are not paying for more than the system needs.
A written report with pictures follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Why it’s worth doing now in Potters Bar
After building work, cleaning the ventilation before people move back in makes sense. Otherwise the dust from the works comes out of the grilles once it’s switched back on. Grease, dust and wear all build up with time.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before work begins.

Schools and colleges are easiest to clean during the holidays, when classrooms are empty.
Offices and retail
Fit-outs in offices and shops leave dust in the ventilation. Cleaning before the new occupants move in makes sense.

What else we do in Potters Bar
In-house cleaning or a specialist?
A few tasks are always specialist work: 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.
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. That part needs specialist access and equipment.

Between visits
After the visit, a few habits help the work last:
- Wipe grilles and diffusers during routine cleaning
- Stick to the filter change schedule
- Make sure nothing is stacked against extract grilles
- Report leaks or damp near ceilings and risers
Pass the paperwork to your facilities or maintenance team, so it’s all in one place. Over time, it shows how quickly the system gets dirty.
Protect the system during building work by switching it off or covering the grilles.
Fixed quotes for ventilation duct cleaning in Potters Bar
Every site gets its own quote. These are the things that affect it:
- Site rules, permits and inductions
- Whether several sites go on one quote
- Travel, parking and unloading
- The condition we find in the survey
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 we will price it together.
Helping us quote
We can often survey from pictures. The most useful are:
- Problems your staff have spotted
- A few general shots of the system
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
When it’s something else
To be straight with you, some problems need a different fix:
- Kitchen extract ductwork, which needs a TR19® Grease clean
- Leaking or broken duct sections
- Problems with how the system is controlled
If in doubt, call 0345 646 2711 or drop us a line and we will say what we think.

Does the law say we must follow TR19?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Are you insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
What does TR19 Air cover?
The two cover different systems: general ventilation for TR19® Air and kitchen extract for TR19® Grease. Under TR19® Air, inspection decides when cleaning is needed.
Who is responsible for fire safety on the premises?
The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
