About our AHU cleaning in St Mary's Bay
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. The work covers drain trays, heating and cooling coils and dampers and louvres, and common reasons people get in touch are units that have only ever had filter changes and filters that are clogged or overdue.
In a smaller place like St Mary's Bay, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What we are called out for in St Mary's Bay
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
It’s time to book a visit if you see:
- Units that have only ever had filter changes
- Intake sections clogged with outdoor debris
- Stale or musty smells from the ventilation
- Dirty coils holding back the airflow
Classrooms and halls at schools such as The Marsh Academy are easiest to work in when pupils are away.
What your quote should include
- When they can work, and whether that’s outside your opening hours
- What happens if part of the system cannot be accessed
- What paperwork you get at the end
- Proof of accreditation you can verify
Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Between visits
Simple habits between visits make a real difference. We recommend:
- Note any water around the unit or leaks below it
- Book the next check in line with the report
- Check the drain tray is emptying during routine visits
- Stick to the filter change plan
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

Part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Common questions in St Mary's Bay
Can you get to a site in St Mary's Bay?
Yes. St Mary's Bay is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you work in St Mary's Bay outside opening hours?
Yes, nights and weekends are routine for us. The work in St Mary's Bay can fit around your hours. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
What happens if you can’t reach some of it?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded for your maintenance team to follow up.
What’s included in an AHU clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, with new panels fitted where necessary.
What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Honest limits
Not every problem is solved by AHU cleaning, and we’ll tell you before any work starts. It won’t put right:
- Damaged coils beyond cleaning
- Airflow problems caused by the system’s design
- Breakdowns that need a mechanical engineer
If you’re not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer.

What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes half a day to a full day per unit, with large plant planned over several shifts. Visits to a place like St Mary's Bay are planned ahead, so we arrive with what the survey says the job needs.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
