Ventilation duct cleaning for kitchens and businesses in Langley
Every ventilation system has ducts bringing air in and ducts taking it out. Dust and debris build up in both, some of which ends up back in the rooms. We clean the ductwork, grilles and diffusers to TR19® Air. If you have construction dust left in ducts after a refit and blocked general extract ductwork, we can put it right, from general extract ductwork, supply ductwork and offices and schools onwards.
For a building in or near Langley, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Visits to a village like Langley are booked in advance, at a time that suits whoever runs the site.
- First the system is surveyed, on site or from pictures and drawings.
- Inspection comes next, with pictures of the inside of the ducts.
- We protect the rooms beneath and switch the system off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- A certificate and before and after pictures follow, with anything not reached recorded.
Getting ready for the visit
- Tell us where we can park and unload
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711 or use the quote form.

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
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.
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Don’t run the ventilation while builders are sanding or cutting
- Wipe grilles and diffusers during routine cleaning
- File each ventilation report with the building records
- Tell your facilities team about dirty diffusers
The report includes a recommended date for the next inspection, in line with the risk-based approach of TR19® Air. Diary it straight away so it isn’t missed.
Protect the system during building work by turning it off or covering the openings.
Why deal with it now?
In healthcare, care and education settings, ventilation cleaning is hard to put off. Clean ducts are part of providing good air for the people inside. Equipment tucked in a roof space or outbuilding near Langley rarely gets looked at unless someone books it.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, ring 0345 646 2711 or email us and we will give you an honest view and a fixed quote.

Schools and colleges
Holidays and weekends are the natural time to clean school ventilation, with nobody in the classrooms.
Extract ductwork
Extract fans pull air through these ducts, so a blocked duct strains them. A clean duct takes the load off.

At about 27 miles from central London, Langley sits well inside the area we cover. Evening, overnight and weekend visits are all possible.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Damp or mould problems coming from the building fabric
- Problems with how the system is controlled

What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
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.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
