Ventilation duct cleaning in Bellfields, done properly
Everyone in the building breathes the air the ventilation brings in. Clean ducts are part of a healthy building, alongside filter changes and AHU maintenance. Typical jobs include ducts that need a clean before handover and dust marks around grilles and ceiling diffusers, on hospitals and care homes, general extract ductwork and toilet extract systems.
Around a place like Bellfields, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What the work involves, part by part
Supply ductwork
We check supply ducts at intervals along each run to see where cleaning is needed.
Grilles and diffusers
Dust marks around grilles can point to dirt further back in the system. The grilles are cleaned and the ducts behind inspected.
What happens if it’s left?
Dust in ducts doesn’t go away on its own. Every year adds to the job, and more of it finds its way back into the building. A quieter site near Bellfields still needs its system looked after.
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, call 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.

Common questions in Bellfields
Is Bellfields within the area you cover?
Yes, Bellfields is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Can you come to Bellfields after we close?
Yes, nights and weekends are routine for us. It means the site in Bellfields keeps running as normal. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.
How does TR19 Air differ from TR19 Grease?
TR19® Air is the part of BESA’s TR19® that covers general supply and extract ventilation, beyond the kitchen. It works on inspection and risk, while TR19® Grease covers kitchen extract systems.
How long will the duct cleaning take?
The clean takes a day or less for a small system and a series of visits for a large one. The survey gives us a clearer idea, and you can call 0345 646 2711, or email photos to arrange it.
Will you look at the ducts before quoting?
Yes. Inspection is the start of the TR19® Air approach, with photos of the inside. We recommend cleaning where the inspection shows it’s due.
How much notice do you need?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Will we have paperwork to show the system was cleaned?
Yes. You get a certificate with the date, location and technician, plus a photo report.
Will you clean the vents in the rooms?
Yes. Where they can be removed, they’re taken down, cleaned and refitted. The rest are cleaned where they are.

What a clean won’t put right

- Condensation caused by the building rather than the ducts
- Ventilation that’s undersized for the building
- Building management settings that run the plant

The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a weekend for a modest system, with large buildings phased floor by floor, and we clear up before we go. Getting to the system matters more than parking in a place like Bellfields, so let us know how to reach it.
- We start by looking at the layout of the ductwork and how it can be reached.
- Ducts are inspected at access points and the condition recorded.
- We protect the rooms beneath and switch the system off.
- Dust and debris are removed from ducts, grilles and diffusers.
- We issue a TR19® certificate and a photo report listing what was cleaned.
How to prepare
- Tell us where we can park and unload
- Tell us the best time to work, such as after service or at a weekend
- Mention any locked doors, roof access or ceiling voids

Common problems we fix in Bellfields
Damp ducts hold onto dirt. Condensation and leaks turn loose dust into a stubborn layer, and it becomes harder to remove.
Common reasons sites call us include:
- Ductwork never cleaned since it was installed
- Dust marks around grilles and ceiling diffusers
- Stuffy rooms and stale air
- Duct runs that can’t be reached for cleaning
Hospitals such as Farnham Road Hospital (about 1.4 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Bellfields are no different.
