What affects the quote in Courtsend
Every site gets its own quote. These are the things that affect it:
- Where the site is and how we reach it
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
- How big the system is
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before we start.
What we need to know
We can often survey from pictures. Try to include:
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Then phone us on 0345 646 2711 or email us.
About our AHU cleaning in Courtsend
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. If you have filters that are clogged or overdue and units that have only ever had filter changes, we can put it right, from heating and cooling coils, filter sections and internal panels onwards.
For a building in or near Courtsend, 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.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

For landlords and multi-site operators
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
What a clean will not put right
In fairness, there are a few things this work will not fix:
- Airflow problems caused by the system’s design
- Ductwork downstream of the unit, which is a separate clean
- Mechanical faults with motors, belts or bearings
Not sure which it is? You can ring 0345 646 2711 or drop us a line and we’ll tell you honestly.
Where we work

A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. Planning a trip to Courtsend ahead is easier for everyone than a rushed one.
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.
Why book with us
- A written report with pictures after every visit
- Trading since 2009
- Fixed quotes from a survey or photos
- Survey first, then a fixed quote

Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We’ll flag anything we notice during the clean.
How often do AHUs need cleaning?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Is a quote from pictures possible?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
