How we handle ventilation duct cleaning in Dunsfold
We get into the ducts through access panels at intervals along the system. If some sections can’t be reached, the report says so, and we can fit new panels for the next clean. Typical jobs include construction dust left in ducts after a refit and dusty supply ductwork that hasn’t been cleaned in years, on grilles and diffusers, toilet extract systems and supply ductwork.
For a building in or near Dunsfold, access is agreed in advance and the visit is planned around the journey.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
Honest limits
A few issues sit outside what this work can do:
- Damaged ductwork beyond cleaning
- Kitchen extract ductwork, which needs a TR19® Grease clean
- Ventilation that is undersized for the building
If you are not sure, just call 0345 646 2711 or use the quote form and we’ll give you a straight answer.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Between visits
Here’s the after-treatment advice, short and simple:
- Make sure nothing is stacked against extract grilles
- Keep the TR19 certificate and photo report in the maintenance log
- Log every filter change
- Diary the next TR19® Air inspection
Keep up with filter changes to protect the ducts. Overdue filters are the quickest way to undo a duct clean.
Protect the system during building work by turning it off or covering the openings.
What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards.

Other services in Dunsfold
What we are called out for in Dunsfold
Refits and building work send dust into ventilation systems, especially when the system runs during the work. That dust can stay in the ducts long after the builders leave.
Any of these means the system needs a check-up:
- Blocked general extract ductwork
- Ventilation that needs a TR19® Air inspection
- Dusty supply ductwork that hasn’t been cleaned in years
- Dust marks around grilles and ceiling diffusers
In Dunsfold, we look inside the system before deciding what needs cleaning.

- How easy every part is to reach
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before any work starts.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Where the site is and what kind of site it is

Questions from Dunsfold
Do you cover smaller places like Dunsfold?
Yes, Dunsfold is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Do you offer ventilation duct cleaning in Dunsfold?
Yes, Dunsfold is covered. You can call us on 0345 646 2711, or email photos and tell us what needs doing.
Do you look at the system first?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.
Who is responsible for fire safety on the premises?
The law calls them the responsible person. That is generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.
What if parts of the system cannot be reached?
Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
Will we have paperwork to show the system was cleaned?
Yes. Every clean comes with a TR19® certificate and a photo report. BESA advises keeping certificates in the maintenance log.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
How much notice do you need?
Earlier is better, especially for out-of-hours work. We usually quote within one working day, and emergencies are covered by our 24/7 line.
