AHU cleaning in Gallows Corner
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. We’re often asked to deal with drain trays holding standing water and odours coming through the supply air, on dampers and louvres, heating and cooling coils and internal panels.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. In Gallows Corner, as elsewhere, cleaning starts with an inspection of what’s there.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Change filters on schedule and log each change
- Do not ignore odours coming through the grilles
- Make sure condensate is draining away
- Keep inspection doors on the unit in good order
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
FAQs for Gallows Corner
Can you work in Gallows Corner outside opening hours?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Can parking be tricky for a job in Gallows Corner?
A loading bay, a visitor permit or off-street space near the site in Gallows Corner makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
What happens on the day
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Expect the work in Gallows Corner to happen after your last customer leaves, not during trading.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Ask for a quote
To get a fixed quote, phone us on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We usually come back within one working day.

Why deal with it now?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. It’s better booked as a planned job in Gallows Corner than handled as an emergency.

Places near Gallows Corner
What else we do in Gallows Corner
How the job changes from site to site
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.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning will not do:
- Building management system faults
- Leaking heating or cooling coils
- Airflow problems caused by the system’s design
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think.
Parts of the system we cover
- Internal panels
- Filter sections
- Dampers and louvres
- Supply and extract fans
- Heating and cooling coils
- Drain trays
What we’re called out for in Gallows Corner
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
It’s time to book a visit if you see:
- Coils clogged with dust and debris
- Air handling units with blocked filters
- Rooms that smell stuffy when the system runs
- Fan sections that haven’t been cleaned in years
Wherever a school like Royal Liberty School has ducted ventilation, a half-term visit keeps the work out of lesson time.
