About our ventilation duct cleaning in Three Mills
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. Common call-outs are for systems with no record of inspection or cleaning and stuffy rooms and stale air, across offices and schools, toilet extract systems and supply ductwork.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Three Mills, dust and debris build up in the units and ductwork over time.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.

- The number of sites or systems
- Whether we need access equipment or extra panels
- A single visit or a regular plan

The cost depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.

Questions from Three Mills
Is parking a problem for work in Three Mills?
A loading bay, a visitor permit or off-street space near the site in Three Mills makes the visit easier to plan. Working overnight, as we often do in London, typically makes it simpler.
Can you work in Three Mills outside opening hours?
Yes. We work evenings, overnight and at weekends. It means the site in Three Mills keeps running as normal. Your opening times are the first thing we ask for.
Do you cover Three Mills?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Three Mills included.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Do you clean grilles and diffusers?
Yes. Removable grilles come down for cleaning and go back up. The rest are cleaned where they are.
How long will the duct cleaning take?
As a guide, it takes anything from a single shift for a small office to a planned programme of nights for a large building. Large buildings can be phased, often out of hours, and we’ll confirm the plan when we quote.
What if parts of the system cannot be reached?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
Who is responsible for fire safety on the premises?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. If you’re not sure, check your lease and fire risk assessment.
Different parts, different methods
Hospitals and care homes
Patients and residents may be more sensitive to dust in the air. Inspecting and cleaning to TR19® Air supports good air quality.
Extract ductwork
Extract fans pull air through these ducts, so a blocked duct strains them. A clean duct takes the load off.
What ventilation duct cleaning can’t fix
A few issues sit outside what this work can do:
- Controls and BMS faults that affect the system
- Ducts that are damaged, corroded or leaking and need replacing
- Ventilation that’s undersized for the building
If in doubt, call 0345 646 2711 or use the quote form and we will say what we think before you book.

- Systems missing access panels
- Ventilation full of debris from building work
- Systems with no record of inspection or cleaning
- Odours carried round the building by the ducts

Three Mills buildings and their air
The FSA’s food hygiene register lists about 52 schools, colleges and universities, about 42 caring premises (care homes, nurseries and hospitals) and about 14 hotels and guest houses with registered kitchens or food service in and around Three Mills, up to about a mile and a half out. Busy, occupied buildings like these are where clean supply air matters most. London plant rooms are often on roofs or in basements reached through occupied floors. About 0.9 miles west of Three Mills is St Clement's Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you run an office near West Ham station, its supply ductwork can gather dust for years before anyone looks inside. For schools like East London Science School, the holidays are the usual time to inspect and clean ventilation.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Store cleaning certificates where auditors can find them
- Keep vents and grilles clear of shelving and stock
- Stick to the filter change schedule
- Wipe grilles and diffusers during routine cleaning
Share the report with whoever looks after the building’s maintenance, so the history stays together. Over time, it shows how quickly the system gets dirty.
Keep filters changed on time. Overloaded or poorly seated filters let dust straight through.
What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes a day or less for a small system and a series of visits for a large one. Security desks and permits-to-work are routine in London, so let us know what your building in Three Mills needs from us.
- We look at the system and any earlier reports.
- Inspection points are chosen and the ducts examined.
- We cover the area below and turn off the system.
- Ducts, grilles and diffusers are cleaned and the debris taken away.

Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Plan for cooking equipment or plant to be off before we arrive

How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
