About our ventilation duct cleaning in Marden Thorn
Ventilation duct cleaning is something we carry out for buildings in Marden Thorn and right across Kent, from offices and schools to hospitals, care homes and shops. Each building gets a survey first and a fixed quote. Common call-outs are for construction dust left in ducts after a refit and ventilation that needs a TR19® Air inspection, on general extract ductwork, grilles and diffusers and offices and schools.
Somewhere as small as Marden Thorn, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
A written report with photos follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What happens on the day
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes from one overnight visit to a phased programme over several weeks. If you can send photos, we can arrive in Marden Thorn knowing what to expect.
- 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.
- The report records what was cleaned, anything not reached and a next inspection date.
Preparing for the visit
- Arrange a key holder or contact on site
- Find the previous report, if there is one
- Allow time for equipment near the work to be turned off and cool down

What else we do in Marden Thorn
When to call us in Marden Thorn
Even good filters let some dust through, so fine dust settles in supply ductwork over the years. Extract ducts collect whatever the rooms give off: dust, fibres and lint.
If you notice any of these, it’s worth a diagnosis:
- Poor airflow from the vents
- Musty smells from the ventilation
- Ventilation that needs a TR19® Air inspection
- Ventilation full of debris from building work
Whether the building is in Marden Thorn itself or nearby, filters, coils, drain trays and ducts are all part of the work.

Between visits
How long the results last depends on use and care. We suggest:
- Watch for water stains around grilles
- Stick to the filter change schedule
- Diary the next TR19® Air inspection
- Store cleaning certificates where auditors can find them
A TR19® certificate and photo report follow every clean. BESA advises keeping certificates in the maintenance log, with the date, location and technician on record.
Good filter maintenance protects the ductwork. Overloaded or poorly seated filters let dust straight through.
For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
