Work in a small place like Theydon Garnon starts with agreeing access and timings.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Different parts, different methods
Extract ductwork
Extract fans pull air through these ducts, so a blocked duct strains them. Clearing the duct helps the fan do its job.
Offices and retail
In offices and retail, we often work evenings, overnight or at weekends so staff and customers are not disturbed.
When to call us in Theydon Garnon
Refits and building work send dust into ventilation systems, especially when the system runs during the work. Plaster, wood and masonry dust can sit in the ducts for years.
If you notice any of these, it’s worth a diagnosis:
- Ventilation that needs a TR19® Air inspection
- Grilles and diffusers streaked with dirt
- Blocked general extract ductwork
- Damp or stale smells from grilles
School buildings such as Theydon Bois Primary School are typically done in the holidays, so classrooms are not disturbed.
Comparing quotes

- How they set the interval to the next visit
- Whether a written report and photos are included
When it’s something else
In fairness, there are a few things this work won’t fix:
- Leaking or broken duct sections
- Building management settings that run the plant
- Damp or mould problems coming from the building fabric
Not sure which it is? You can call 0345 646 2711 or drop us a line and we’ll tell you honestly.

Why act early in Theydon Garnon
Facilities teams are regularly asked to show evidence of ventilation hygiene. A TR19® certificate and photo report from a recent clean give them that. Somewhere as small as Theydon Garnon, losing a kitchen or building to a fault is felt by everyone who uses it.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.

How we price ventilation duct cleaning
We don’t publish a price list, because no two systems are the same. The quote depends on:
- What state the system is in
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
- When the work can happen, such as evenings, overnight or weekends
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Asking for a quote
What to send for a quote:
- Problems your staff have spotted
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
To get a fixed quote, ring 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You will typically have a quote within one working day.
Theydon Garnon questions
Do you work in villages like Theydon Garnon?
Yes. Theydon Garnon is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Do you do school ventilation cleaning in Theydon Garnon in the summer holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Theydon Garnon. Send us your term dates when you give us a ring on 0345 646 2711 or use the quote form, and we’ll fit the work in.
How often should ventilation ductwork be cleaned?
That varies with the building, the filters and how hard the system works. Regular inspection tells you when it’s due.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained so the area stays clean.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Will you clean the vents in the rooms?
Yes, along with the ducts behind them. They show up in the photo report before and after.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
Do we need to close while you work?
Not typically. The area we are working in has to be out of use while we are there, so we book a time when it would be closed anyway.

What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.

The process
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, and that takes a shift or two for a small system, longer for a whole building. If you can send photos, we can arrive in Theydon Garnon knowing what to expect.
- First the system is surveyed, on site or from photos and drawings.
- We inspect inside the ductwork at set points and photograph it.
- The area below is protected and the system switched off.
- We clean the ductwork, grilles and diffusers through access panels.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Let us know about parking and loading
- Have your last certificate or report to hand

Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
