Ventilation duct cleaning in Felden
We get into the ducts through access panels along each run. If some sections cannot be reached, the report says so, and we can fit new panels so they’re covered next time. Common call-outs are for stuffy rooms and stale air and ductwork with too few access panels to clean, across toilet extract systems, general extract ductwork and offices and schools.
For a building near Felden, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What happens if it’s left?
If a building in Felden has just been refitted, now is the time to clean the ductwork. Otherwise the dust from the works comes out of the grilles once it’s switched back on. You choose the date of a planned visit, and a breakdown never asks.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Wipe grilles and diffusers during routine cleaning
- Tell your facilities team about dirty diffusers
- Watch for water stains around grilles
- Keep the TR19 certificate and photo report in the maintenance log
Change filters on schedule so the clean ducts stay clean. Overdue filters let dust straight back in.
Regular inspection is the core of TR19® Air. Scheduled inspections spot dust before it becomes a major job.
Honest limits
A few issues sit outside what this work can do:
- Controls and BMS faults that affect the system
- Design problems with the ductwork layout
- Cooking extract ducts, which are a separate specialist clean
If you’re not sure, just give us a ring on 0345 646 2711, or send details by email and we will give you a straight answer.
Parts of the system we cover

- Hospitals and care homes
- Supply ductwork
- Offices and schools
- Toilet extract systems
- Grilles and diffusers
Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Different parts, different methods
Extract ductwork
General extract ductwork removes stale air from rooms, toilets and washrooms. They collect dust, lint and fibres and slowly narrow.
Hospitals and care homes
People in hospitals and care homes can be more vulnerable to poor air. Inspection-led cleaning under TR19® Air helps keep systems in good condition.
What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes from one overnight visit to a phased programme over several weeks. Tell us about any gates, ladders or locked plant areas at your site near Felden when you book.
- We survey the system from drawings, pictures or a site visit.
- We inspect inside the ductwork at set points and photograph it.
- The area below is protected and the system switched off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- A certificate and before and after photos follow, with anything not reached recorded.
How to prepare
- Let us know about parking and loading
- Find the previous report, if there is one
- Name a contact who can let us in at the agreed time
Getting a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.

When to call us in Felden
Planned maintenance tends to focus on fans and filters, not the ducts. A building in Felden can have well-serviced plant and dirty ductwork at the same time.
Most sites get in touch when they notice something like this:
- Blocked general extract ductwork
- Ductwork never cleaned since it was installed
- Ductwork that hasn’t been inspected
- Grilles and diffusers streaked with dirt
Classrooms and halls at schools such as Nash Mills Church of England Primary School are easiest to work in when pupils are away.

Felden questions
Do you cover smaller places like Felden?
Yes. Villages and rural sites across the South East are part of our work, Felden included. The journey is planned ahead, so a few details about the route help.
Can a school’s ventilation in Felden be done out of term time?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 17 schools and colleges with food registrations within roughly a mile and a half of Felden. Send us your term dates when you give us a ring on 0345 646 2711 or drop us a line, and we will fit the work in.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Will we have paperwork to show the system was cleaned?
Yes. You get a TR19® certificate and a report with before and after pictures. BESA advises keeping certificates in the maintenance log.
Is there a survey before the work?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
How long will the duct cleaning take?
It takes a shift or two for a small system, longer for a whole building. The size of the system and the access make the biggest difference.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Ring any time and tell us what’s happened.
