How we handle ventilation duct cleaning in Four Marks
Beyond the kitchen, TR19® Air covers the ordinary supply and extract systems that serve offices, schools and other buildings. It’s risk-based and inspection-led, so every job starts with a look inside the ducts. Typical jobs include ductwork that hasn’t been inspected and damp or stale smells from grilles, across offices and schools, toilet extract systems and grilles and diffusers.
Visits to a place like Four Marks are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

We won’t sell you work that does not address the problem, so here are the limits:
- Design problems with the ductwork layout
- Damaged ductwork beyond cleaning
- Condensation caused by the building rather than the ducts
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think before you book.
Parts of the system we cover
- Supply ductwork
- Grilles and diffusers
- Hospitals and care homes
- Offices and schools
- General extract ductwork
- Toilet extract systems
What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a day or less for a small system and a series of visits for a large one. In a smaller place like Four Marks, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We look at the system and any earlier reports.
- Inspection points are chosen and the ducts examined.
- We cover the area below and turn off the system.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- We report on the work, listing any inaccessible sections and the next inspection date.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
Getting a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.
Related advice
Different parts, different methods
Extract ductwork
General extract ductwork removes stale air from rooms, toilets and washrooms. Lint, dust and fibres gather inside and slowly narrow.
Schools and colleges
Busy classrooms send a lot of dust and fibre into extract ducts. Inspection shows when cleaning is due.
Managing agents and facilities teams in Four Marks
We also work for facilities teams across offices, schools and healthcare across Hampshire. Work can be phased by floor, building or site around the people who use them.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Your questions about ventilation duct cleaning in Four Marks
Can you come to Four Marks after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Four Marks does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Do you cover smaller places like Four Marks?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
How much does ventilation duct cleaning cost in Four Marks?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll typically reply within one working day.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Do you inspect before cleaning?
Yes, always. We check the layout, access and condition, so the quote is fixed before any work starts.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Signs you need ventilation duct cleaning in Four Marks
Ventilation hygiene often gets left out of planned maintenance. Plant can be well serviced while the ductwork goes untouched for years.
Most sites get in touch after spotting something like this:
- Ductwork that hasn’t been inspected
- Systems missing access panels
- Ventilation full of debris from building work
- Rooms that feel airless when the system runs
If you run a surgery, dental practice or care home near Four Marks, clean ventilation matters as much to you as to a hospital like Alton Community Hospital (about 3.3 miles north-east).
What your quote should include
- Whether the figure could change on the day
- Whether they recommend a next date
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the quote shows VAT
Why it’s worth doing now in Four Marks
Dust in ducts doesn’t go away on its own. The longer it’s left, the more there is to remove, and more of it finds its way back into the building. A visit arranged in advance is far less disruptive than a callout on a busy day.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, give us a ring on 0345 646 2711, or send details by email for straight advice and a fixed quote.
