Ventilation duct cleaning in Keymer
Every ventilation system has ducts bringing air in and ducts taking it out. Dust and debris build up in both, and some of it is blown back into the building. Our cleaning covers the ducts, grilles and diffusers, to TR19® Air. The work covers general extract ductwork, grilles and diffusers and supply ductwork, and people most often call us about stuffy rooms and stale air and odours carried round the building by the ducts.
For a building near Keymer, the visit is planned around how it’s used, and the journey is planned ahead. The method doesn’t change: inspect first, clean, then record what was done.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Aftercare tips
A little care between visits keeps the system in better shape. Our advice:
- Wipe grilles and diffusers during routine cleaning
- Log every filter change
- Tell your facilities team about dirty diffusers
- Keep the TR19 certificate and photo report in the maintenance log
Pass the paperwork to your facilities or maintenance team, so the history stays together. Over time, it shows how quickly the system gets dirty.
Protect the system during building work by turning it off or covering the openings.
In-house cleaning or a specialist?
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 shows an inspector that the system is looked after between visits, next to our reports.

How it works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and hand over the paperwork. On site, the work takes a weekend for a modest system, with large buildings phased floor by floor. In a place like Keymer, we fit the visit around your hours.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- Before photos are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- We take after pictures and send the certificate and report.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear the space around the work
- Find the previous report, if there is one

Advice
Ventilation in Keymer buildings
Going by the FSA’s register, there are about 3 care, childcare and hospital premises serving food within roughly a mile and a half of the centre of Keymer. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Keymer, the closest hospital is The Dene Hospital, roughly 3.2 miles north-west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. About 40 miles out from central London, Keymer is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you.
For schools like The Windmills Junior School, the holidays are the usual time to inspect and clean ventilation. Workplaces around Hassocks station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
Keymer is about 2 miles south of Burgess Hill, in West Sussex. We provide ventilation duct cleaning for commercial premises of every kind in Keymer and the rest of West Sussex. Keymer is one of 371 places in West Sussex we cover for commercial clients. We also work in Brighton, around 6 miles away.

For rail, the closest station is Hassocks station, about 0.5 miles west of the centre. Well-known places in the area include The Dene Hospital (3.2 miles north-west) and Clayton Castle (1.2 miles south-west). Not far away are Ditchling Beacon and Bedelands Farm Nature Reserve.
Why act early in Keymer
After building work, cleaning the ventilation before people move back in makes sense. Otherwise construction dust left in the ducts is blown out once the system runs. Light use slows the build-up but does not stop it.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

What a clean won’t put right
Not every problem is solved by ventilation duct cleaning, and we’ll tell you before we start. It does not solve:
- Cooking extract ducts, which are a separate specialist clean
- Controls and BMS faults that affect the system
- Condensation caused by the building rather than the ducts
If you are not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer before booking.
Where we work
- General extract ductwork
- Toilet extract systems
- Hospitals and care homes
- Offices and schools
- Grilles and diffusers
- Supply ductwork
When to call us in Keymer
Even good filters let some dust through, so fine dust settles in supply ductwork over the years. Extract ducts pick up dust, fibres and fluff from the rooms they serve.
Clients normally contact us after spotting something like this:
- Ventilation that needs a TR19® Air inspection
- Systems missing access panels
- Dirty diffusers dropping dust into rooms
- Odours carried round the building by the ducts
Hospitals such as The Dene Hospital (about 3.2 miles north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Keymer are no different.

How the job changes from site to site
Hospitals and care homes
In healthcare and care settings, there’s no quiet time. The work is sequenced with staff to keep disruption down.
Extract ductwork
A dirty extract duct makes its fan work harder. A clean duct takes the load off.

Can you work in Keymer outside opening hours?

How much does ventilation duct cleaning cost in Keymer?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, normally ready within one working day.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Do we need to close while you work?
Not typically. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.
Are grilles and diffusers included?
Yes. Removable grilles come down for cleaning and go back up. Fixed ones are cleaned in place.
What is TR19® Air?
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, and kitchen extract falls under TR19® Grease.
How much time does a ventilation clean need?
Work on site 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 phone us on 0345 646 2711 or use the quote form to arrange it.
