How we handle ventilation duct cleaning in Merton
A dusty duct in a building in Merton is more than an eyesore. It slows the air, strains the fans and can be blown back out of the grilles. A clean puts the system back as it should be. We’re often asked to deal with dust marks around grilles and ceiling diffusers and rooms that feel airless when the system runs, across general extract ductwork, supply ductwork and toilet extract systems.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Merton is normally planned out of hours. Loading and parking are planned with the building first.
We have been trading since 2009, and we are 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.

Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. 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.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Why deal with it now?
An inspection-led approach avoids cleaning ducts that do not need it. Putting the inspection off just means you do not know where you stand. Every month a London system goes without attention adds to what has to be done later.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before we start.

Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Include grilles in the cleaning rota
- Get leaks near ductwork fixed quickly
- Report dust blowing from grilles straight away
- File each ventilation report with the building records
Pass the paperwork to your facilities or maintenance team, so it’s all in one place. Year on year, it shows how fast dust builds up.
Keep filters changed on time. Overdue or badly fitted filters let dust into the supply ducts.
What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes a shift or two for a small system, longer for a whole building, and the area is cleaned down before we leave. We fit London jobs around the building rather than the other way round, so a visit in Merton is typically out of hours.
- First we check the layout and any past paperwork.
- 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.
- The report records what was cleaned, anything not reached and a next inspection date.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload

To get a fixed quote, phone us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll usually have a quote within one working day.

Part by part
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.
Supply ductwork
Supply ductwork delivers conditioned air to each room. Fine dust that gets past the filters settles along the runs, and it’s cleaned out through access panels.
What ventilation duct cleaning can’t fix
Not every problem is solved by ventilation duct cleaning, and we will tell you before any work starts. It will not put right:
- Grease in kitchen extract systems, cleaned to TR19® Grease instead
- A system that isn’t designed to move enough air
- Damaged ductwork beyond cleaning
If you are not sure, just ring 0345 646 2711, or email photos and we will give you a straight answer.

Ventilation in Merton buildings
There are about 39 schools, colleges and universities, about 49 caring premises (care homes, nurseries and hospitals) and about 5 hotels, B&Bs and guest houses on the FSA’s food hygiene register within 1.5 miles or so of the middle of Merton. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. The nearest hospital to Merton is St George's Hospital, about 1.1 miles north-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
For schools like Merton Abbey Primary School, the holidays are the usual time to inspect and clean ventilation. If you run an office near Haydons Road station, its supply ductwork can gather dust for years before anyone looks inside. If you run a surgery, dental practice or care home near Merton, clean ventilation matters as much to you as to a hospital like St George's Hospital (about 1.1 miles north-east).

Merton questions
Can ventilation in schools around Merton be cleaned out of term?
Yes, holiday work suits schools best. There are about 39 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Merton. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you work in Merton outside opening hours?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
Will you look at the ducts before quoting?
Yes. We always survey first, on site or from pictures and drawings, and then quote a fixed price.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. We normally quote within one working day, and emergencies are covered by our 24/7 line.
How often should ventilation ductwork be cleaned?
Under TR19® Air, the answer comes from inspecting the ducts. Heavily used buildings, or those with vulnerable occupants, may need attention more often.
