Ventilation cleaning in Hudnall Corner

How we price ventilation duct cleaning
You will get a fixed price before we start. It’s based on:
- The condition of the system
- Site requirements such as sign-in and permits
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
Helping us quote
We can often survey from photos. Try to include:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Wide pictures of the system and the area around it
- Where the site is and what kind of site it is
- Any access panels or hatches you can see
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.
Ventilation duct cleaning in Hudnall Corner, done properly
TR19® Air is the part of BESA’s TR19® that deals with general supply and extract ventilation. It works by inspecting first and cleaning where the risk calls for it, so we look before we clean. If you have ventilation that needs a TR19® Air inspection and toilet and washroom extracts full of fluff, we can put it right.
Work in a small place like Hudnall Corner starts with agreeing access and timings.
The report is your 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, ready for your insurer.

Hudnall Corner: your questions answered
Can you come to Hudnall Corner after we close?
Yes, evening, overnight and weekend work is normal for us. That way a site in Hudnall Corner doesn’t have to lose a day’s trading. Just call us on 0345 646 2711, or email photos with your opening times and we will plan around them.
Do you clean school ventilation in Hudnall Corner in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Hudnall Corner, it pays to plan holiday dates ahead. Just phone us on 0345 646 2711 or send us an email with your term dates and we will plan around them.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
Are you fully insured?
Yes. We are fully insured, and we can share the details when you need them.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Where does the waste go?
We take it away when we go. While we work, it’s kept contained to keep the area clean.
What happens if parts of the ductwork can’t be reached?
Nothing is hidden: any section we couldn’t get into is listed. We can install panels to open those sections up.
When to call us in Hudnall Corner
Why does it matter?: dusty ducts can blow debris back into rooms, restrict airflow and make fans work harder. In hospitals, care homes and schools, clean air is especially important.
The symptoms we’re asked about most include:
- Rooms that feel airless when the system runs
- Odours carried round the building by the ducts
- Extract ducts clogged with lint and dust
- Ducts that need a clean before handover
In Hudnall Corner, we look inside the system before deciding what needs cleaning.

Different parts, different methods
Hospitals and care homes
Hospitals and care homes are occupied day and night. We plan the order of work with the site team to keep disruption down.
Schools and colleges
Classrooms full of people, paper and coats produce plenty of dust. Regular inspection keeps on top of it.
Multi-site and managed buildings
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Get leaks near ductwork fixed quickly
- Flag any dust coming out of the vents
- Keep vents and grilles clear of shelving and stock
- Wipe grilles and diffusers during routine cleaning
If there’s building work planned, protect the ventilation. Switch it off or cover the grilles while dusty work goes on.
Regular inspection is the core of TR19® Air. Inspecting on a schedule catches build-up before it becomes a big clean.
