How we handle AHU cleaning in Marden Thorn
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. The work covers internal panels, filter sections and dampers and louvres, and common reasons people get in touch are drain trays holding standing water and filters that are clogged or overdue.
For a building in or near Marden Thorn, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Fixed quotes for AHU cleaning in Marden Thorn
The price is fixed before any work begins. It’s based on:
- When the work can happen, such as evenings, overnight or weekends
- Whether several sites go on one quote
- The condition of the system
- One-off work versus a regular cycle
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

What to send for a quote:
- Your last certificate, test record or report
- Where the site is and what kind of site it is

How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. If the van will struggle with a lane or gateway near Marden Thorn, let us know and we’ll plan around it.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Clear the space around the work
- Let us know about permits to work or site inductions
How to get a quote
Photos are the quickest way to a quote: 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.

Looking after it afterwards
After the visit, a few habits help the work last:
- Report musty smells from the vents right away
- Keep inspection doors on the unit in good order
- Look at the condensate drain whenever the unit is serviced
- Keep filter changes on time and recorded
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
When to call us in Marden Thorn
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Marden Thorn, that’s air they breathe for hours at a time.
Look out for these warning signs:
- Debris and leaves in the fresh air intake
- Stale or musty smells from the ventilation
- Air handling units never cleaned inside
- Blocked condensate drains and slimy trays
For buildings in and around Marden Thorn, TR19® Air cleaning starts with an inspection.
Before booking anyone
- How areas they can’t reach will be recorded
- What paperwork you get at the end
- Whether they’re fully insured
- Whether the quote shows VAT
For landlords and multi-site operators

Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.

What a clean will not put right
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning will not do:
- Leaking heating or cooling coils
- Mechanical faults with motors, belts or bearings
- Airflow problems caused by the system’s design
If in doubt, give us a ring on 0345 646 2711, or email photos and we’ll say what we think before you book.
Parts of the system we cover
- Dampers and louvres
- Filter sections
- Drain trays
- Internal panels
- Heating and cooling coils
- Supply and extract fans
What happens if it’s left?
Standing water in a drain tray doesn’t clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. In a small place like Marden Thorn, a system that fails can take a site out of use.
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711 or send us an email, and we will explain what it covers.
