AHU Cleaning in Chalkwell
Cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Chalkwell, surveyed first and signed off with a written report and photos. Ask us for a fixed quote.
- Units needing a clean before a new tenant or handover
- Drain trays holding standing water
- Filters that are clogged or overdue
Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Keep filter changes on time and recorded
- Clear leaves and litter away from the intake
- Keep the certificate and photo report with the plant records
- Diary the inspection date recommended in the report
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
About our AHU cleaning in Chalkwell
We clean air handling units for buildings in Chalkwell and across Southend-on-Sea, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. We’re often asked to deal with drain trays holding standing water and plant that needs cleaning after a refit, on dampers and louvres, supply and extract fans and internal panels.
Around a place like Chalkwell, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 0.9 miles north-east of Chalkwell is Southend University Hospital, the nearest hospital.

Why it’s worth doing now in Chalkwell
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. In a smaller place like Chalkwell, a site that has to close is felt quickly.
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 play a part.

- Photo reports with every job
- A fixed price before any work starts

Landlords, agents and facilities managers
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.

What else we do in Chalkwell
How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and we clear up before we go. In a smaller place like Chalkwell, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
How to prepare
- Have your last certificate or report to hand
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote

Common questions in Chalkwell
Do you work at weekends in Chalkwell?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Chalkwell needn’t be disturbed. Just call 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Do you cover smaller places like Chalkwell?
Yes. Chalkwell 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.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What happens if you can’t reach some of it?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can quote for both.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
