Dudswell ventilation duct cleaning
Ventilation duct cleaning for businesses, landlords and public buildings in Dudswell. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Grilles and diffusers streaked with dirt
- Supply ducts with years of dust inside
- Ductwork with too few access panels to clean
Why deal with it now?
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. In a place like Dudswell, ductwork and fans are easy to forget until something goes wrong.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, ring 0345 646 2711 or email us for straight advice and a fixed quote.

How we price ventilation duct cleaning
You will get a fixed price before we start. It’s based on:
- What state the system is in
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
- Where the site is and how we reach it
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Wide photos of the system and the area around it
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Common problems we fix in Dudswell
Filters never catch everything, and that fine dust settles along the supply ducts. Extract ducts collect whatever the rooms give off: dust, fibres and lint.
Signs it’s time to call us include:
- Ventilation full of debris from building work
- Ductwork that hasn’t been inspected
- Damp or stale smells from grilles
- Dust marks around grilles and ceiling diffusers
Hospitals such as Hemel Hempstead Hospital (about 5.9 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Dudswell are no different.

Supply ductwork
We check supply ducts at intervals along each run to see where cleaning is needed.
Hospitals and care homes
In care settings, keeping dust contained is a priority. The area is protected, and debris contained and removed.
What ventilation duct cleaning cannot fix
In fairness, there are a few things this work won’t fix:
- Damp or mould problems coming from the building fabric
- Grease in kitchen extract systems, cleaned to TR19® Grease instead
- Ventilation that’s undersized for the building
If in doubt, call us on 0345 646 2711 or drop us a line and we will say what we think.

Questions from Dudswell
Can the work in Dudswell be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. That way a site in Dudswell does not have to lose a day’s trading. When you call us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Can you clean school ventilation in Dudswell during the holidays?
Yes, holiday work suits schools best. There are about 6 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Dudswell. Send us your term dates when you ring 0345 646 2711 or send us an email, and we will fit the work in.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Are grilles and diffusers included?
Yes, along with the ducts behind them. You’ll see them in the before and after pictures.
Will we have to shut during the visit?
Not normally. We need the work area to ourselves while we are on site, so we book a time when it would be closed anyway.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.
What should I send you?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a shift or two for a small system, longer for a whole building. We agree a date with you, plan the drive to Dudswell and turn up when the site is quiet.
- First we plan when the work can happen, often out of hours.
- Access panels are opened along each run.
- Before photos are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- After photos are taken and the certificate and report issued.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure someone can let us in and lock up afterwards
- Plan for cooking equipment or plant to be off before we arrive

Between visits
To keep the system working properly between visits:
- Don’t run the ventilation while builders are sanding or cutting
- Store cleaning certificates where auditors can find them
- Tell your facilities team about dirty diffusers
- Make sure nothing is stacked against extract grilles
If there’s building work planned, protect the ventilation. Turn off the system or cover the openings during dusty jobs.
Fix leaks and damp near the ductwork quickly, as wet dust is much harder to clean.
