Ventilation duct cleaning in Round Bush, done properly
Toilet, washroom and general extract ducts gather dust, fluff and debris. Supply ducts carry anything the filters miss. Both are cleaned, with the area protected and the mess contained. Typical jobs include ductwork with too few access panels to clean and supply ducts with years of dust inside, across toilet extract systems, hospitals and care homes and grilles and diffusers.
Work in a small place like Round Bush starts with agreeing access and timings.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
What happens on the day
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes from one overnight visit to a phased programme over several weeks. The timing of a visit to Round Bush is set by you, and the travel is our side of the planning.
- 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.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- We report on the work, listing any inaccessible sections and the next inspection date.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear loose items from the work area
- Let us know when the site is closed or quiet
How to get a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

What ventilation duct cleaning cannot fix
Ventilation duct cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Building management settings that run the plant
- Damp or mould problems coming from the building fabric
- Leaking or broken duct sections
If in doubt, call 0345 646 2711 or use the quote form and we’ll say what we think.

Why deal with it now?
Facilities teams are regularly asked to show evidence of ventilation hygiene. Having a recent certificate and photo report for a building in Round Bush answers the question. In a small place like Round Bush, a system that fails can take a site out of use.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, call 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.

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.
Supply ductwork
Dust in supply ducts can be blown straight into occupied rooms. Cleaning it deals with the source.
Round Bush: your questions answered
Can a school’s ventilation in Round Bush be done out of term time?
Yes, and it’s the easiest time to do it. There are about 8 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Round Bush. Booking early in the term gives the best choice of holiday dates.
Can you get to a site in Round Bush?
Yes, Round Bush is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Does the law say we must follow TR19?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005 in England and Wales.
Who is the responsible person?
That depends on who controls the premises. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. We usually quote within one working day, and emergencies are covered by our 24/7 line.
What happens if parts of the ductwork cannot be reached?
Accessible sections are cleaned and the others recorded. Fitting access panels tends to be the answer, and we can fit them.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.
How long will the duct cleaning take?
It takes anything from a single shift for a small office to a planned programme of nights for a large building. The size of the system and the access make the biggest difference.

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
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.
