Ventilation Duct Cleaning in Lashenden
One call covers TR19 Air cleaning of general supply and extract ventilation ductwork in commercial buildings in Lashenden, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Ventilation that needs a TR19® Air inspection
- Ventilation full of debris from building work
- Damp or stale smells from grilles
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Stick to the filter change schedule
- Keep grilles and diffusers dusted
- Diary the next TR19® Air inspection
- Store cleaning certificates where auditors can find them
A TR19® certificate and photo report follow every clean. Keep them in the maintenance log, with the date, location and technician recorded.
Good filter maintenance protects the ductwork. Overloaded or poorly seated filters let dust straight through.
How we handle ventilation duct cleaning in Lashenden
Toilet, washroom and general extract ducts gather dust, fluff and debris. Supply ducts carry anything the filters miss. Both are cleaned, with the area protected and the mess contained. If you’re dealing with blocked general extract ductwork and duct runs that can’t be reached for cleaning, we can help, from general extract ductwork, offices and schools and grilles and diffusers onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

The process
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a shift or two for a small system, longer for a whole building. Somewhere as small as Lashenden, the date and timings are agreed with you well before the day.
- First we check the layout and any past paperwork.
- We inspect the ducts at chosen points to see where cleaning is needed.
- The work area is protected and the system switched off.
- 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
- Tell us where we can park and unload
- Arrange a key holder or contact on site
- Agree a time when the area can be out of use
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Advice
For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
When the building owner and the occupier are different, 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.
What affects the cost of ventilation duct cleaning
A fixed price needs a few facts first. We look at:
- Whether several sites go on one quote
- The condition we find in the survey
- Site requirements such as sign-in and permits
- Whether it’s a one-off visit or part of a schedule
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
Helping us quote
To speed up the quote, please include:
- The times we could work without disrupting the site
- Wide photos of the system and the area around it
- The paperwork from the last visit, if you have it
- How we’d reach plant on a roof or in a plant room
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before work begins.

About 40 miles out from central London, Lashenden is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included. About 3.9 miles south of Lashenden is Benenden Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Around Lashenden, as anywhere, ventilation cleaning begins with an inspection. If you run a surgery, dental practice or care home near Lashenden, clean ventilation matters as much to you as to a hospital like Benenden Hospital (about 3.9 miles south).

Common questions in Lashenden
Can you work in Lashenden outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The work in Lashenden can fit around your hours. Tell us your opening hours when you ask for a quote.
Do you offer ventilation duct cleaning in Lashenden?
Yes. We work across London and the South East, and Lashenden is part of that. Get in touch with the details and we will arrange a survey.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
How much notice should we give?
Earlier is better, especially for out-of-hours work. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Will you clean the vents in the rooms?
Yes. Removable grilles come down for cleaning and go back up. The rest are cleaned where they are.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
Honest limits
Ventilation duct cleaning cannot fix everything, and we’d rather say so up front. It does not solve:
- Ducts that are damaged, corroded or leaking and need replacing
- Problems with how the system is controlled
- Ventilation that’s undersized for the building
If in doubt, call us on 0345 646 2711 or use the quote form and we will say what we think.
