How we handle ventilation duct cleaning in St John's Wood
When the work is finished, you get a TR19® certificate and before and after photos. The report lists what we cleaned, any sections not reached and a recommended next inspection, so you have it all on record. The work covers general extract ductwork, hospitals and care homes and toilet extract systems, and people most often call us about dirty diffusers dropping dust into rooms and odours carried round the building by the ducts.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in St John's Wood is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What ventilation duct cleaning looks like in St John's Wood
There are about 83 schools, colleges and universities, about 51 hospitals, care homes and childcare premises and about 80 hotels, B&Bs and guest houses on the FSA’s food hygiene register in St John's Wood and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. About less than half a mile south of St John's Wood is Hospital of St John and St Elizabeth, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
If you manage offices or shops near South Hampstead station, their ventilation can be inspected and cleaned out of hours. School buildings such as George Eliot Primary School are typically done in the holidays, so classrooms are not disturbed.
St John's Wood is about 1 mile south of Hampstead, in Greater London. We provide ventilation duct cleaning for commercial premises of every kind in St John's Wood and the rest of Greater London. We cover 764 places across Greater London, large and small.
Work in NW8, NW6 and NW3 follows the same survey, fixed quote and written report as everywhere else we cover. That includes premises on The Lane, Hall Road and Hill Road and the roads around them. You will find St John's Wood on the A5205, which makes it straightforward for our technicians to reach for ventilation duct cleaning.

Common problems we fix in St John's Wood
Moisture in ducts makes dust stick. Condensation and leaks turn loose dust into a stubborn layer, and it becomes harder to remove.
Common reasons sites call us include:
- Toilet and washroom extracts full of fluff
- Damp or stale smells from grilles
- Poor airflow from the vents
- Grilles and diffusers streaked with dirt
If you run a surgery, dental practice or care home near St John's Wood, clean ventilation matters as much to you as to a hospital like Hospital of St John and St Elizabeth (about within half a mile south).
What your quote should include
- Whether inaccessible sections are listed on the report
- How they set the interval to the next visit
- What hours they’ll be on site
- Proof of accreditation you can verify
In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
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.
How we price ventilation duct cleaning
The diagnosis comes before the price. We look at:
- The condition we find in the survey
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
- Access, including roofs, risers and ceiling voids
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.
Asking for a quote
To help us quote quickly, please include:
- Your opening hours and when the area is out of use
- The site address and the type of premises
- Any access panels or hatches you can see
- Any previous report or certificate

How the job changes from site to site
Extract ductwork
Extract ducts take air out of toilets, washrooms and general areas. Lint, dust and fibres gather inside and slowly narrow.
Hospitals and care homes
Dust control matters during work in occupied care settings. The area is protected, and debris contained and removed.

When it’s something else
Not every problem is solved by ventilation duct cleaning, and we’d rather say so up front. It won’t put right:
- Controls and BMS faults that affect the system
- Design problems with the ductwork layout
- Condensation caused by the building rather than the ducts
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we will tell you honestly.

On site, it takes anything from a single shift for a small office to a planned programme of nights for a large building. If your building in St John's Wood has sign-in rules, permits or key holders, mention them when you book.
- We agree timings that suit the building, including evenings and weekends.
- Access panels are opened along each run.
- Before photos are taken and the ducts cleaned section by section.
