What ventilation duct cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what ventilation duct cleaning will not do:
- Ventilation that is undersized for the building
- Cooking extract ducts, which are a separate specialist clean
- Building management settings that run the plant
Not sure which it is? You can give us a ring on 0345 646 2711 or send us an email and we’ll tell you honestly before you book.

Ventilation duct cleaning in Darenth, done properly
Toilet, washroom and general extract ducts gather dust, fluff and debris. Supply ducts carry anything the filters miss. We clean both, keeping the work tidy and the building protected. Typical jobs include rooms that feel airless when the system runs and supply ducts with years of dust inside, across supply ductwork, offices and schools and hospitals and care homes.
Work in a small place like Darenth starts with agreeing access and timings.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Include grilles in the cleaning rota
- Keep vents and grilles clear of shelving and stock
- Store cleaning certificates where auditors can find them
- Protect the system from construction dust
Before any works, think about the ducts. Switch it off or cover the grilles while dusty work goes on.
TR19® Air works through regular inspection. Inspecting on a schedule catches build-up before it becomes a big clean.
Signs you need ventilation duct cleaning in Darenth
It matters for the people inside: dirt in the ducts can come back out of the grilles, slow the air and add strain on fans. In hospitals, care homes and schools, clean air is especially important.
Most sites get in touch when they notice one of these:
- Musty smells from the ventilation
- Dust marks around grilles and ceiling diffusers
- Ventilation full of debris from building work
- Stuffy rooms and stale air
If you manage a school such as Greenlands Primary School, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- How VAT is shown on the quote
- What’s included in the scope, part by part
- What happens if part of the system can’t be accessed
- Whether they’re fully insured
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. 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.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes a weekend for a modest system, with large buildings phased floor by floor. Rural roads and tight entrances are worth telling us about before a visit to Darenth.
- First the system is surveyed, on site or from pictures and drawings.
- We inspect inside the ductwork at set points and photograph it.
- The area below is protected and the system switched off.
- Dust and debris are removed from ducts, grilles and diffusers.
- A certificate and before and after pictures follow, with anything not reached recorded.
Before we arrive
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.

- Where the site is and how we reach it
- The condition of the system
- Site requirements such as sign-in and permits

- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
- Problems your staff have spotted

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
FAQs for Darenth
Do you do school ventilation cleaning in Darenth in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Darenth, it pays to plan holiday dates ahead. Send us your term dates when you ring 0345 646 2711, or email photos, and we’ll fit the work in.
Can the work in Darenth be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Darenth needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
How often should ventilation ductwork be cleaned?
It depends on the building, how the system is used and what inspection finds. Inspecting regularly shows when cleaning is needed.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Is TR19 cleaning required by law?
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 cleaning to TR19® is the recognised way to show grease is under control.
