When something else is needed
Ventilation duct cleaning can’t fix everything, and we will tell you before any work starts. It doesn’t solve:
- Ventilation that is undersized for the building
- Building management settings that run the plant
- Leaks from roofs, pipes or walls into the ductwork
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly before you book.

Ventilation duct cleaning for kitchens and businesses in Crabtree
TR19® Air is the part of BESA’s TR19® that deals with general supply and extract ventilation. It works by inspecting first and cleaning where the risk calls for it, so every job starts with a look inside the ducts. If you have blocked general extract ductwork and rooms that feel airless when the system runs, we can put it right, from grilles and diffusers, supply ductwork and offices and schools onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Why act early in Crabtree
Dust streaks around grilles and stale rooms suggest the ducts need looking at. Acting early keeps the clean simpler. Out of sight is the usual reason a rural system goes too long without attention.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.

What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Ventilation duct cleaning in Crabtree: local notes
Crabtree, about 34 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site. Crabtree’s nearest hospital, Horsham Hospital, is about 4.9 miles north-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Hospitals such as Horsham Hospital (about 4.9 miles north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Crabtree are no different. If you manage a school such as Newells Preparatory School, ventilation cleaning is best booked for the holidays.
Crabtree is about 5 miles south-east of Horsham, in West Sussex. Crabtree gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with photos.

The process
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes a weekend for a modest system, with large buildings phased floor by floor. In a small place like Crabtree, the journey is planned ahead and the visit arranged around the site’s hours.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- We photograph the ducts, then clean each section in turn.
- Grilles and diffusers are cleaned and refitted.
- After photos are taken and the certificate and report issued.
Getting ready for the visit
- Mention any parking or loading restrictions
- Clear the space around the work
- Tell us about site rules, permits or sign-in

What else we do in Crabtree
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Aftercare tips
Once we have finished, these simple steps help:
- Make sure nothing is stacked against extract grilles
- Keep to the inspection interval in your report
- Include grilles in the cleaning rota
- Report leaks or damp near ceilings and risers
Share the report with whoever looks after the building’s maintenance, so it’s all in one place. Over time, it shows how quickly the system gets dirty.
Keep filters changed on time. Overloaded or poorly seated filters let dust straight through.
