Kent · Ventilation duct cleaning
Ventilation duct cleaning in Stone, Kent
For TR19 Air cleaning of general supply and extract ventilation ductwork in commercial buildings in Stone, one call is all it takes: survey, fixed quote, work and sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Blocked general extract ductwork
- Duct runs that can’t be reached for cleaning
- Systems with no record of inspection or cleaning
Common problems we fix in Stone
Damp ducts hold onto dirt. Where there’s condensation or a leak, dust clings and builds faster, which is harder to shift later.
It’s time to book a visit if you see:
- Musty smells from the ventilation
- Poor airflow from the vents
- Systems with no record of inspection or cleaning
- Construction dust left in ducts after a refit
Hospitals such as Darent Valley Hospital (about 1 mile south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Stone are no different.
Before booking anyone
- Proof of accreditation you can verify
- Proof of insurance
- Whether the quote is based on a survey or pictures
- Whether the whole system is included, or only the parts that are easy to reach
Ventilation duct cleaning for kitchens and businesses in Stone
Ductwork is reached through access panels at intervals along the system. Where there are not enough panels to reach every section, we note the uncleaned parts in the report, and we can fit new panels so they’re covered next time. If you’re dealing with ventilation full of debris from building work and systems missing access panels, we can help.
For a building near Stone, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, and that takes from one overnight visit to a phased programme over several weeks. Around Stone, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- We photograph the ducts, then clean each section in turn.
- Grilles and diffusers are cleaned and refitted.
- After pictures are taken and the certificate and report issued.
Getting ready for the visit
- Move anything stored near the system
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.

Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Flag any dust coming out of the vents
- Keep vents and grilles clear of shelving and stock
- Book the next inspection on the date the report recommends
- Keep the TR19 certificate and photo report in the maintenance log
Share the report with whoever looks after the building’s maintenance, so it’s all in one place. Over time, it shows how quickly the system gets dirty.
Fix leaks and damp near the ductwork quickly, as wet dust is much harder to clean.
In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
What affects the quote in Stone
The price is fixed before any work begins. It’s based on:
- The condition of the system
- Where the site is and how we reach it
- Working hours and out-of-hours timing
- The number of sites or systems
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
- Wide pictures of the system and the area around it
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.
Your questions about ventilation duct cleaning in Stone
Do you cover smaller places like Stone?
Yes. Villages and rural sites across the South East are part of our work, Stone included. Photos of the system and directions to the site help us plan the visit.
Do you clean school ventilation in Stone in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Stone, the Food Standards Agency lists about 5 schools and colleges with registered kitchens within a mile and a half or so. Just phone us on 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
Do you survey the system first?
Yes. Inspection is the start of the TR19® Air approach and record what we find. We recommend cleaning where the inspection shows it’s due.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
What happens to the waste?
We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
How does TR19 Air differ from TR19 Grease?
It covers ventilation hygiene for supply and extract systems in offices, schools, hospitals and other buildings. Kitchen extract is covered separately, by TR19® Grease.
How much notice should we give?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What the work involves, part by part
Supply ductwork
We check supply ducts at intervals along each run before deciding what to clean.
Grilles and diffusers
Every duct ends at a grille or diffuser in the room. We clean them as part of the job, so the room side matches the duct side.
Honest limits
Before you book, it helps to know what’s not included:
- Leaks from roofs, pipes or walls into the ductwork
- A system that is not designed to move enough air
- Controls and BMS faults that affect the system
If you are not sure, just give us a ring on 0345 646 2711 or email us and we will give you a straight answer.
