Ventilation duct cleaning in Chipperfield
Beyond the kitchen, TR19® Air covers the ordinary supply and extract systems that serve offices, schools and other buildings. It works by inspecting first and cleaning where the risk calls for it, so every job starts with a look inside the ducts. Typical jobs include poor airflow from the vents and duct runs that can’t be reached for cleaning, on toilet extract systems, supply ductwork and general extract ductwork.
For a building in or near Chipperfield, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
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.
Your questions about ventilation duct cleaning in Chipperfield
Can you get to a site in Chipperfield?
Yes, we work in villages as well as towns, and Chipperfield is covered. A survey first, from photos or a visit, means we arrive with the right kit.
Do you do school ventilation cleaning in Chipperfield in the summer holidays?
Yes, out-of-term visits are normal for schools. Around Chipperfield, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. You can give us a ring on 0345 646 2711 or drop us a line with the dates the site is empty.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
What about areas you cannot get to?
We record them on the report, with photos where possible, and we explain what access is needed, for example new access panels.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
How much time does a ventilation clean need?
Typically, the work takes a shift or two for a small system, longer for a whole building. Bigger sites are split into stages, and we’ll confirm the plan when we quote.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
When something else is needed
Some problems need a different service or another trade:
- Kitchen extract ductwork, which needs a TR19® Grease clean
- Leaking or broken duct sections
- Ventilation that is undersized for the building
Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we will tell you honestly before booking.
What the work covers
- General extract ductwork
- Offices and schools
- Supply ductwork
- Grilles and diffusers
- Hospitals and care homes
- Toilet extract systems
What the work involves, part by part
Schools and colleges
Schools and colleges are easiest to clean during the holidays, when classrooms are empty.
Hospitals and care homes
In healthcare and care settings, there’s no quiet time. The work is sequenced with staff so care carries on.
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Stick to the filter change schedule
- Flag any dust coming out of the vents
- Keep grilles and diffusers dusted
- Do not block grilles with furniture or storage
What was cleaned is listed, along with any parts that weren’t accessible, with photos before and after. We’ll suggest where new access panels would help.
Protect the system during building work by switching it off or covering the grilles.
Why act early in Chipperfield
After building work, cleaning the ventilation before people move back in makes sense. Otherwise the dust from the works comes out of the grilles once it’s switched back on. It’s simpler to plan the work at Chipperfield now than to arrange it in a hurry later.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before any work starts.
Why book with us
- Full insurance on every job
- In business since 2009
- A fixed price before any work starts
- We diagnose before we treat
