Ventilation duct cleaning in North Lee, done properly
Ventilation duct cleaning is something we carry out for buildings in North Lee and right across Buckinghamshire, from offices and schools to hospitals, care homes and shops. Each building gets a survey first and a fixed quote. Typical jobs include supply ducts with years of dust inside and ductwork with too few access panels to clean, on toilet extract systems, grilles and diffusers and hospitals and care homes.
In a village or hamlet like North Lee, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
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. Cleaning inside ducts and units is specialist work.
What affects the quote in North Lee
The survey tells us what the work involves. The main factors are:
- The size of the system
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
- Working hours and out-of-hours timing
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
Asking for a quote
What to send for a quote:
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
- Any previous report or certificate
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Getting a quote doesn’t take long. Call or email with a few details and you will usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
North Lee questions
Can you work in North Lee outside opening hours?
Yes, nights and weekends are routine for us. That way a site in North Lee does not have to lose a day’s trading. When you give us a ring on 0345 646 2711 or send us an email, mention when the site is quiet.
Can you get to a site in North Lee?
Yes. Villages and rural sites across the South East are part of our work, North Lee included. Photos of the system and directions to the site help us plan the visit.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. Some sites still need a visit, and we will say so.
What happens if parts of the ductwork cannot be reached?
We clean what we can reach and note the rest. Fitting access panels tends to be the answer, and we can fit them.
What should I send you?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we will ask.
What is TR19® Air?
TR19® Air is the part of BESA’s TR19® that covers general supply and extract ventilation, rather than kitchen extract. It’s risk-based and led by inspection, while TR19® Grease covers kitchen extract systems.
When to call us in North Lee
Moisture in ducts makes dust stick. Where there’s condensation or a leak, dust clings and builds faster, which is harder to shift later.
What we’re most often called out for:
- Systems with no record of inspection or cleaning
- Ductwork with too few access panels to clean
- Dust marks around grilles and ceiling diffusers
- Ducts that need a clean before handover
Healthcare ventilation, from large hospitals like Stoke Mandeville Hospital (about 1.7 miles north) to small clinics, depends on clean filters, coils and ducts.
Before you book anyone
- How areas they cannot reach will be recorded
- What insurance they carry
- Whether the quote is based on a survey or photos
- What records you’ll receive afterwards
What we do, step by step
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Pictures of the system and its access let us plan the work in North Lee before we set off.
- We start by looking at the layout of the ductwork and how it can be reached.
- Inspection comes next, with pictures of the inside of the ducts.
- We protect the rooms beneath and switch the system off.
- We clean the ductwork, grilles and diffusers through access panels.
- A certificate and before and after pictures follow, with anything not reached recorded.
How to prepare
- Name a contact who can let us in at the agreed time
- Let us know about parking and loading
- Let us know when the site is closed or quiet

Looking after it afterwards
Once we’ve finished, these simple steps help:
- Keep grilles and diffusers dusted
- Make sure nothing is stacked against extract grilles
- Diary the next TR19® Air inspection
- File each ventilation report with the building records
A TR19® certificate and photo report follow every clean. BESA advises keeping certificates in the maintenance log, with the date, location and technician on record.
Make sure there are enough access panels to inspect and clean the ducts. Hidden sections are the ones that get worst.
What a clean won’t put right
We won’t sell you work that does not address the problem, so these are the things it won’t cover:
- Design problems with the ductwork layout
- Leaks from roofs, pipes or walls into the ductwork
- Cooking extract ducts, which are a separate specialist clean
Not sure which it is? You can call us on 0345 646 2711 or send us an email and we will tell you honestly.
