Your questions about AHU cleaning in Clayhall
Do you clean school ventilation in Clayhall in the holidays?
Yes, holiday work suits schools best. With about 17 schools and colleges on the FSA’s register within roughly a mile and a half of Clayhall, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Do you cover smaller places like Clayhall?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, ring 0345 646 2711, or send details by email and tell us about the site and its opening hours.
How much notice do you need?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
How long will the unit be out of action?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Large plant can be split over several shifts, and you can phone us on 0345 646 2711, or send details by email to plan it.
AHU cleaning in Clayhall
Where a building in Clayhall has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. The work covers supply and extract fans, dampers and louvres and drain trays, and common reasons people get in touch are air handling units never cleaned inside and stale or musty smells from the ventilation.
In a smaller place like Clayhall, 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.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Keeping the system healthy
Once we have finished, these simple steps help:
- Keep inspection doors on the unit in good order
- Clear leaves and litter away from the intake
- Report musty smells from the vents straight away
- Store the TR19 paperwork where auditors can find it
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.

If in doubt, call 0345 646 2711 or drop us a line and we’ll say what we think.

The process
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 from a few hours for a compact unit to a day or more for a large one. Tell us when your site near Clayhall is quiet and the visit will be booked for then.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Let us know about permits to work or site inductions

Part by part
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Managing agents and facilities teams in Clayhall
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
What happens if it’s left?
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Booking now means the visit to Clayhall is planned around you, not forced by a breakdown.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before any work starts.
Why book with us
- Survey first, then a fixed quote
- A fixed price before any work starts
- Accredited under CHAS and SafeContractor, with ISO 9001
- Fully insured

How we price AHU cleaning
The survey tells us what the work involves. We look at:
- The condition we find in the survey
- Travel, parking and unloading
- The times the site is available
- Whether several sites go on one quote
The cost depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
What we need to know
What to send for a quote:
- Any previous report or certificate
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any access panels or hatches you can see
Getting a quote does not take long. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
