Ventilation duct cleaning for kitchens and businesses in Brentford
Every ventilation system has ducts bringing air in and ducts taking it out. Dust and debris build up in both, some of which ends up back in the rooms. Our cleaning covers the ducts, grilles and diffusers, to TR19® Air. The work covers offices and schools, supply ductwork and grilles and diffusers, and people most often call us about supply ducts with years of dust inside and ventilation that needs a TR19® Air inspection.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Brentford.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What your team can do, and what needs us
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.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Part by part
Extract ductwork
Toilet and washroom extract can carry moisture as well as dust, so the dust tends to cling. They’re cleaned and their condition recorded.
Supply ductwork
Supply runs are inspected at set points first before deciding what to clean.
Fixed quotes for ventilation duct cleaning in Brentford
Every site gets its own quote. These are the things that affect it:
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
What we need to know
When you call or email, these details help:
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
- Your last certificate, test record or report
If you need ventilation duct cleaning in Brentford, call 0345 646 2711 or email us. Tell us what kind of premises it is and when it’s open, and send photos or your last report if you can. A fixed quote typically follows within one working day.
For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Brentford buildings and their air
Food Standards Agency records list about 49 schools, colleges and universities, about 54 hospitals, care homes and childcare premises and about 12 hotels, B&Bs and guest houses registered as food businesses within about 1.5 miles of central Brentford. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. London plant rooms are often on roofs or in basements reached through occupied floors. About 1.4 miles south-west of Brentford is West Middlesex University 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 a surgery, dental practice or care home near Brentford, clean ventilation matters as much to you as to a hospital like West Middlesex University Hospital (about 1.4 miles south-west). If you manage offices or shops near Brentford station, their ventilation can be inspected and cleaned out of hours. For schools like St Paul's CofE Primary School, the holidays are the usual time to inspect and clean ventilation.

Common questions in Brentford
Can parking be tricky for a job in Brentford?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Do you do school ventilation cleaning in Brentford in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 49 schools and colleges on the FSA’s register within roughly a mile and a half of Brentford, it pays to plan holiday dates ahead. You can ring 0345 646 2711, or send details by email with the dates the site is empty.
Who has the legal duty for fire safety?
It depends on the building. 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.
Do we get a certificate after the clean?
Yes. You get a TR19® certificate and a report with before and after photos. Keep them in the maintenance log.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
How much does ventilation duct cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll typically reply within one working day.
Can you clean ventilation out of hours?
Yes. The work is planned around the building’s hours. Holidays suit schools, and evenings or weekends suit offices.
How much time does a ventilation clean need?
Expect it to take from one overnight visit to a phased programme over several weeks. The size of the system and the access make the biggest difference.
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Don’t run the ventilation while builders are sanding or cutting
- Do not block grilles with furniture or storage
- Flag any dust coming out of the vents
- File each ventilation report with the building records
Keep up with filter changes to protect the ducts. Overdue filters are the quickest way to undo a duct clean.
Regular inspection is the core of TR19® Air. Inspecting on a schedule catches build-up before it becomes a big clean.
How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes a day or less for a small system and a series of visits for a large one. In a London area like Brentford, parking, loading and building access are planned before the day of the work.
- First we check the layout and any past paperwork.
- Inspection points are chosen and the ducts examined.
- We cover the area below and turn off the system.
- We clean the system and remove the debris from site.
- We report on the work, listing any inaccessible sections and the next inspection date.
Before we arrive
- Dig out any earlier paperwork for the system
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms

Photos are the quickest way to a quote: 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.
