Ventilation cleaning in Holwellbury
Ventilation duct cleaning for Holwellbury and the surrounding area: diagnosis first, then a fixed quote, the work and a report with pictures. Ask us for a fixed quote.
- Dust marks around grilles and ceiling diffusers
- Blocked general extract ductwork
- Damp or stale smells from grilles
Between visits
Aftercare is simple, and it helps at the next visit:
- Diary the next TR19® Air inspection
- Switch the ventilation off or cover grilles during dusty building work
- Tell your facilities team about dirty diffusers
- Keep the TR19 certificate and photo report in the maintenance log
If there’s building work planned, protect the ventilation. Switch it off or cover the grilles while dusty work goes on.
Make sure there are enough access panels to inspect and clean the ducts. Hidden sections are the ones that get worst.
Ventilation duct cleaning in Holwellbury
Dust in ventilation ductwork is not only a cleanliness issue. It slows the air, strains the fans and can be blown back out of the grilles. Cleaning restores the clear airway the system was designed with. The work covers toilet extract systems, grilles and diffusers and hospitals and care homes, and the jobs we see most are extract ducts clogged with lint and dust and stuffy rooms and stale air.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Different parts, different methods
Schools and colleges
The work is fitted around term dates and events and agree access with the site team.
Grilles and diffusers
Dark streaks round a ceiling diffuser can be a sign of dirty supply air. The grilles are cleaned and the ducts behind inspected.
FAQs for Holwellbury
Will you come out to Holwellbury?
Yes. Villages and rural sites across the South East are part of our work, Holwellbury included. Let us know about access, parking and anything unusual about getting there when you book.
Can you come to Holwellbury after we close?
Yes, we can come after you close and finish before you open. It means the site in Holwellbury keeps running as normal. When you give us a ring on 0345 646 2711, or send details by email, mention when the site is quiet.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
Can you look after several sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.
Do you survey the system first?
Yes. TR19® Air is inspection-led, so we look inside the ducts at set points and record what we find. Cleaning is recommended where it’s needed.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What information do you need?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
What about areas you cannot get to?
Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
Honest limits
In fairness, there are a few things this work won’t fix:
- Ducts that are damaged, corroded or leaking and need replacing
- Condensation caused by the building rather than the ducts
- Controls and BMS faults that affect the system
If in doubt, call us on 0345 646 2711 or use the quote form and we will say what we think.

What affects the quote in Holwellbury
You’ll get a fixed price before work begins. It takes into account:
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
- The size of the system
- One-off work versus a regular cycle
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711, or email photos, and we’ll explain what it covers.
What we need to know
There’s no need for technical detail. It helps if you can send:
- The roof, plant room or outside wall the system runs to
- Photos showing the whole system and its surroundings
- Where the site is and what kind of site it is
- The times we could work without disrupting the site
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or email photos.
How it works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes a day or less for a small system and a series of visits for a large one. Visits to a village like Holwellbury are booked in advance, at a time that suits whoever runs the site.
- We look at the system and any earlier reports.
- We inspect the ducts at chosen points to see where cleaning is needed.
- The work area is protected and the system switched off.
- We clean the system and remove the debris from site.
- We report on the work, listing any inaccessible sections and the next inspection date.
Preparing for the visit
- Let us know when the site is closed or quiet
- Make sure someone can let us in and lock up afterwards
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.
