Different parts, different methods
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
AHU cleaning for kitchens and businesses in Mapledurham
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. The work covers supply and extract fans, heating and cooling coils and filter sections, and the jobs we see most are dirty coils holding back the airflow and air handling units due a clean after building work.
Work in a small place like Mapledurham starts with agreeing access and timings.
Good records are part of the job. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Why act early in Mapledurham
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. Somewhere as small as Mapledurham, losing a kitchen or building to a fault is felt by everyone who uses it.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

Landlords, agents and facilities managers
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.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
When it’s something else
A few issues sit outside what this work can do:
- Leaking heating or cooling coils
- Ventilation that was badly designed in the first place
- Building management system faults
If in doubt, call us on 0345 646 2711, or email photos and we will say what we think.
Where we work
- Drain trays
- Dampers and louvres
- Filter sections

How the visit works
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. The timing of a visit to Mapledurham is set by you, and the travel is our side of the planning.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Preparing for the visit
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend
- Mention any parking or loading restrictions

What affects the quote in Mapledurham
Sites vary more than people expect. What affects the quote:
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- How many systems or sites are involved
- The scale of the work
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
What we need to know
Before you ask for a quote, gather:
- The postcode and the type of business
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

Aftercare tips
After the visit, a few habits help the work last:
- Keep filter changes on time and recorded
- Don’t ignore odours coming through the grilles
- Make sure condensate is draining away
- Plan the next inspection before the last report gets filed away
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Mapledurham buildings and their air
The FSA’s food hygiene register lists about 3 schools, colleges and universities and about 9 care, childcare and hospital premises with registered kitchens or food service within 1.5 miles or so of the middle of Mapledurham. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Mapledurham is about 41 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours. Battle Hospital is the nearest hospital, about 2.5 miles south-east of Mapledurham. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you manage a school such as Purley CofE Primary School, ventilation cleaning is best booked for the holidays. If you run a surgery, dental practice or care home near Mapledurham, clean ventilation matters as much to you as to a hospital like Battle Hospital (about 2.5 miles south-east).
