Ventilation duct cleaning in Upper Holloway
In a building in Upper Holloway, the people inside spend hours breathing what the ventilation delivers. Clean ducts are part of a healthy building, as much as clean filters and a well-kept AHU. Typical jobs include grilles and diffusers streaked with dirt and ductwork never cleaned since it was installed, across general extract ductwork, supply ductwork and toilet extract systems.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Upper Holloway, dust and debris build up in the units and ductwork over time.
We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Upper Holloway questions
Do you clean school ventilation in Upper Holloway in the holidays?
Yes, and it’s the easiest time to do it. There are about 47 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Upper Holloway. You can give us a ring on 0345 646 2711, or send details by email with the dates the site is empty.
Is parking a problem for work in Upper Holloway?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Do you work evenings and weekends?
Yes. We fit the work around when the building is in use. Schools are often done in the holidays and offices out of hours.
Are you accredited?
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 are fully insured.
How does TR19 Air differ from TR19 Grease?
The two cover different systems: general ventilation for TR19® Air and kitchen extract for TR19® Grease. TR19® Air takes an inspection-led, risk-based approach.
What information do you need?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we will ask.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What happens if parts of the ductwork cannot be reached?
Accessible sections are cleaned and the others recorded. Fitting access panels tends to be the answer, and we can quote for them.
What the work involves, part by part
Schools and colleges
Schools and colleges are easiest to clean during the holidays, with nobody in the classrooms.
Grilles and diffusers
Dust marks around grilles can point to dirt further back in the system. We clean the grilles and look at what’s behind them.
What we do, step by step
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the ventilation duct cleaning, tidy up and leave you the report. The visit itself takes from one overnight visit to a phased programme over several weeks. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Upper Holloway.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- We photograph the ducts, then clean each section in turn.
- Grilles and diffusers are cleaned and refitted.
- After pictures are taken and the certificate and report issued.
Before we arrive
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms
- Arrange a key holder or contact on site
Getting a quote
We do not 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 send you a fixed quote. To get going, call us on 0345 646 2711, or send details by email.
Related advice
Staff cleaning versus specialist work
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
What affects the cost of ventilation duct cleaning
The quote reflects the site in front of us. We consider:
- One-off work versus a regular cycle
- The scale of the work
- Working hours and out-of-hours timing
- The number of sites or systems
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.
Asking for a quote
When you call or email, it’s useful to have:
- The roof, plant room or outside wall the system runs to
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see
- The site address and the type of premises
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Do you need ventilation duct cleaning in Upper Holloway?
Planned maintenance tends to focus on fans and filters, not the ducts. A building in Upper Holloway can have well-serviced plant and dirty ductwork at the same time.
It’s time to book a visit if you see:
- Ductwork that hasn’t been inspected
