Managing agents and facilities teams in Maypole
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
AHU cleaning for kitchens and businesses in Maypole
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. The work covers dampers and louvres, filter sections and supply and extract fans, and the jobs we see most are filters that are clogged or overdue and blocked condensate drains and slimy trays.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Maypole, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What affects the quote in Maypole
Some jobs are bigger than they look, and some smaller. The main factors:
- Site requirements such as sign-in and permits
- Where the site is and how we reach it
- The number of sites or systems
- How big the system is
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before work begins.
Helping us quote
You don’t need the technical terms. Just send:
- Any previous report or certificate
- Detail shots of panels, filters and grilles
- Problems your staff have spotted
- Where the site is and what kind of site it is
To get a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We usually come back within one working day.
Maypole buildings and their air
For Maypole, the closest hospital is Orpington Hospital, roughly 2 miles west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. London plant rooms are often on roofs or in basements reached through occupied floors.
School buildings such as Chelsfield Primary School are typically done in the holidays, so classrooms aren’t disturbed. Workplaces around Knockholt station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
Maypole is about 3 miles south-east of Orpington, in Greater London. If you need AHU cleaning in Maypole, please call us on 0345 646 2711 or drop us a line for a fixed quote.

What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
How the visit works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes from a few hours for a compact unit to a day or more for a large one. Night and weekend working is normal for us in London, and a site in Maypole is no exception.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Dig out any earlier paperwork for the system
- Tell us about site rules, permits or sign-in
- Name a contact who can let us in at the agreed time
Get a fixed quote
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, give us a ring on 0345 646 2711 or drop us a line.
Advice
Aftercare tips
After the visit, a few habits help the work last:
- Do not ignore odours coming through the grilles
- Keep filter changes on time and recorded
- Book the next check in line with the report
- Don’t store bins or materials near the intake
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Why act early in Maypole
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. Leaving it on a busy London site only adds to the work.
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 work begins.
Why choose Duct Doctor in Maypole
- Survey first, then a fixed quote
- A written report with photos after each visit

- In business since 2009

Common problems we fix in Maypole
Whatever surrounds a building in Maypole, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Most sites get in touch when they notice one of these:
- Dirty filters cutting the airflow
- Stale or musty smells from the ventilation
- Plant that needs cleaning after a refit
- Drain trays holding standing water
Healthcare buildings such as Orpington Hospital, about 2 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Maypole, yours matters too.

Common questions in Maypole
Is parking a problem for work in Maypole?
A loading bay, a visitor permit or off-street space near the site in Maypole makes the visit easier to plan. Night visits tend to make loading easier on London streets.
Is Maypole in your area for AHU cleaning?
Yes, Maypole is covered. A fixed quote usually follows within one working day of the survey details.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Can you clean the AHU out of hours?
Yes. We time the work to fit the building’s hours. Healthcare and care settings are planned with staff.
What if parts of the system can’t be reached?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
