Ventilation duct cleaning in Hounslow, Greater London
Ventilation duct cleaning across Hounslow and nearby, timed so the site keeps working and finished with a written report and photos.

Ventilation duct cleaning in Hounslow
Inspection comes first. We look inside the ductwork at set points and record what’s there, and cleaning is recommended where the inspection shows it’s due. That keeps the work in proportion to the risk. The work covers general extract ductwork, toilet extract systems and hospitals and care homes, and common reasons people get in touch are musty smells from the ventilation and grilles and diffusers streaked with dirt.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Hounslow, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What happens on the day
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes from one overnight visit to a phased programme over several weeks. In a London area like Hounslow, parking, loading and building access are planned before the day of the work.
- We agree timings that suit the building, including evenings and weekends.
- We open the ductwork through its access panels.
- We photograph the ducts, then clean each section in turn.
- We clean the grilles and diffusers and put them back.
- We take after photos and send the certificate and report.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system
- Let us know about permits to work or site inductions

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
What happens if it’s left?
An inspection-led approach avoids cleaning ducts that don’t need it. Skipping it leaves you guessing. A building in Hounslow may have flats or offices above and alongside, and a fault in the system can affect them too.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before work begins.

Different parts, different methods
Grilles and diffusers
Grilles and diffusers are where the ducts meet the room. We clean them as part of the job, so dust on them isn’t blown back in.
Supply ductwork
We check supply ducts at intervals along each run before deciding what to clean.
Signs you need ventilation duct cleaning in Hounslow
Moisture in ducts makes dust stick. Where there’s condensation or a leak, dust clings and builds faster, which is harder to shift later.
These are the problems we see most often:
- Ducts that need a clean before handover
- Ductwork never cleaned since it was installed
- Ventilation that needs a TR19® Air inspection
- Poor airflow from the vents
School buildings such as Chatsworth Primary School are typically done in the holidays, so classrooms aren’t disturbed.

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. 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.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
What ventilation duct cleaning looks like in Hounslow
The FSA’s food hygiene register lists about 40 schools, colleges and universities, about 52 hospitals, care homes and childcare premises and about 13 hotels and B&Bs with registered kitchens or food service within 1.5 miles or so of the middle of Hounslow. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot. Hounslow’s nearest hospital, South Middlesex Hospital, is about 0.9 miles south-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
For workplaces around Hounslow station with mechanical ventilation, cleaning can be done in the evening or at weekends. South Middlesex Hospital, about 0.9 miles south-east, is the nearest hospital to Hounslow, and healthcare sites of every size need their supply air kept clean.

Common questions in Hounslow
Can a school’s ventilation in Hounslow be done out of term time?
Yes, and it’s the easiest time to do it. There are about 40 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hounslow. Tell us your holiday dates and we will book the visit for when the site is empty.
What do you need to know about parking in Hounslow?
Tell us where a van can stop near your site in Hounslow, and about any building rules on loading. Night visits tend to make loading easier on London streets.
Do you provide a report?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
Can you clean ventilation out of hours?
Yes. We fit the work around when the building is in use. Holidays suit schools, and evenings or weekends suit offices.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
What does TR19 Air cover?
It’s BESA’s guidance for ventilation hygiene in general supply and extract systems, beyond the kitchen. It works on inspection and risk, and kitchen extract falls under TR19® Grease.
Do you clean grilles and diffusers?
Yes. Where they can be removed, they’re taken down, cleaned and refitted. The rest are cleaned where they are.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
