Ventilation duct cleaning for kitchens and businesses in Chenies
Extract ducts from toilets, changing rooms and general areas collect dust and lint. Supply ducts carry anything the filters miss. We clean both, keeping the work tidy and the building protected. If you’re dealing with extract ducts clogged with lint and dust and dust marks around grilles and ceiling diffusers, we can help, from grilles and diffusers, general extract ductwork and supply ductwork onwards.
In a village or hamlet like Chenies, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Common problems we fix in Chenies
Damp ducts hold onto dirt. Where there’s condensation or a leak, dust clings and builds faster, and it becomes harder to remove.
Look out for these warning signs:
- Construction dust left in ducts after a refit
- Duct runs that cannot be reached for cleaning
- Ductwork that hasn’t been inspected
- Dirty diffusers dropping dust into rooms
School buildings such as Chenies School are typically done in the holidays, so classrooms aren’t disturbed.
Questions to ask before you book
- If they look at the system before pricing
- What hours they’ll be on site
- When the next visit should be, and why
- What happens if part of the system can’t be accessed
What happens if it’s left?
Dust in ducts does not go away on its own. Every year adds to the job, and more of it finds its way back into the building. If the system at a site near Chenies fails, there may be nowhere nearby to move to.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before work begins.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Controls and BMS faults that affect the system
- Kitchen extract ductwork, which needs a TR19® Grease clean
- Ventilation that is undersized for the building
Not sure which it is? You can call us on 0345 646 2711 or email us and we will tell you honestly.

Common questions in Chenies
Can a school’s ventilation in Chenies be done out of term time?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Chenies. Send us your term dates when you phone us on 0345 646 2711 or send us an email, and we will fit the work in.
Do you work in villages like Chenies?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
What should I send you?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
How does TR19 Air differ from TR19 Grease?
It’s BESA’s guidance for ventilation hygiene in general supply and extract systems, rather than kitchen extract. It works on inspection and risk, while TR19® Grease covers kitchen extract systems.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
Will we have to shut during the visit?
Not normally. The area we are working in has to be out of use while we are there, so we book a time when it would be closed anyway.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
How we price ventilation duct cleaning
The quote reflects the site in front of us. We consider:
- Site rules, permits and inductions
- Whether we need access equipment or extra panels
- The number of sites or systems
- Travel, parking and unloading
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, call us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.
Asking for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- The paperwork from the last visit, if you have it
- The postcode and the type of business
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.

Schools and colleges
We plan the work around the school calendar, with access agreed with the caretaker or site manager.
Offices and retail
In offices and retail, we often work evenings, overnight or at weekends to keep the space open.
Between visits
Simple habits between visits make a real difference. We recommend:
- Store cleaning certificates where auditors can find them
- Switch the ventilation off or cover grilles during dusty building work
- Book the next inspection on the date the report recommends
- Log every filter change
Pass the paperwork to your facilities or maintenance team, so it’s all in one place. Year on year, it shows how fast dust builds up.
Keep filters changed on time. Overdue or badly fitted filters let dust into the supply ducts.
What happens on the day
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Somewhere like Chenies, lanes, gates and parking are worth mentioning in advance.
- We start by looking at the layout of the ductwork and how it can be reached.
- Inspection comes next, with pictures of the inside of the ducts.
- Floors and furniture are covered and the ventilation turned off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- You get a TR19® certificate and photo report, with any unreached sections noted.
How to prepare
- Agree a time when the area can be out of use
- Mention any locked doors, roof access or ceiling voids
- Clear the space around the work
Get a fixed quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
