The process
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, which takes a day or less for a small system and a series of visits for a large one. Visits to a village like South Mimms are booked in advance, at a time that suits whoever runs the site.
- We start by looking at the layout of the ductwork and how it can be reached.
- We inspect inside the ductwork at set points and photograph it.
- The area below is protected and the system switched off.
- Dust and debris are removed from ducts, grilles and diffusers.
- You get a TR19® certificate and photo report, with any unreached sections noted.
How to prepare
- Let us know about permits to work or site inductions
- Allow time for equipment near the work to be turned off and cool down
- Let us know when the site is closed or quiet
Getting a quote
Getting a quote doesn’t take long. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

About our ventilation duct cleaning in South Mimms
TR19® Air is the part of BESA’s TR19® that deals with general supply and extract ventilation. It’s risk-based and inspection-led, so we look before we clean. The work covers general extract ductwork, supply ductwork and grilles and diffusers, and common reasons people get in touch are systems missing access panels and toilet and washroom extracts full of fluff.
For a building in or near South Mimms, access is agreed in advance and the visit is planned around the journey.
Each visit ends with a written report and photos, 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.

Leave it or put it right?
In healthcare, care and education settings, ventilation cleaning is hard to put off. Good indoor air starts with a clean system. In a small place like South Mimms, a system that fails can take a site out of use.
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 will explain each part.

Common problems we fix in South Mimms
Planned maintenance tends to focus on fans and filters, not the ducts. A building in South Mimms can have well-serviced plant and dirty ductwork at the same time.
Look out for any of the following:
- Extract ducts clogged with lint and dust
- Dust marks around grilles and ceiling diffusers
- Ventilation that needs a TR19® Air inspection
- Rooms that feel airless when the system runs
Classrooms and halls at schools such as St Giles' CofE Primary School are easiest to work in when pupils are away.
What to look for in a quote
- Exactly which parts of the system are covered
- Whether a survey comes first
- If the quote is a fixed price or an estimate
- Whether inaccessible sections are listed on the report
What ventilation duct cleaning cannot fix

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.

FAQs for South Mimms
Do you work at weekends in South Mimms?
Yes, out-of-hours work is a big part of what we do. That way a site in South Mimms does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Do you do school ventilation cleaning in South Mimms in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of South Mimms.

What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Who is responsible for fire safety on the premises?
That depends on who controls the premises. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
What does TR19 Air cover?
TR19® Air deals with general ventilation, while TR19® Grease deals with kitchen extract. TR19® Air takes an inspection-led, risk-based approach.
What information do you need?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
What if there are not enough access panels?
Those sections are recorded as not cleaned in the report, so it’s clear what’s outstanding. New access panels can be installed so they’re covered next time.
Between visits
Once we’ve finished, these simple steps help:
- Flag any dust coming out of the vents
- Keep filters changed on time
- Keep the TR19 certificate and photo report in the maintenance log
- Keep vents and grilles clear of shelving and stock
Pass the paperwork to your facilities or maintenance team, so it’s all in one place. Year on year, it shows how fast dust builds up.
Regular inspection is the core of TR19® Air. Inspecting on a schedule catches build-up before it becomes a big clean.
For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
