Different parts, different methods
Supply ductwork
We check supply ducts at intervals along each run to see where cleaning is needed.
Hospitals and care homes
Dust control matters during work in occupied care settings. We protect the work area and take everything away.
How we handle ventilation duct cleaning in South Darenth
When the work is finished, you get a TR19® certificate and before and after pictures. The report lists what we cleaned, any sections not reached and a recommended next inspection, giving the ventilation a clean bill of health on paper. We’re often asked to deal with duct runs that can’t be reached for cleaning and ductwork never cleaned since it was installed, on toilet extract systems, hospitals and care homes and supply ductwork.
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.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

FAQs for South Darenth
Will you come out to South Darenth?
Yes, we work in villages as well as towns, and South Darenth is covered. Photos of the system and directions to the site help us plan the visit.
Is South Darenth in your area for ventilation duct cleaning?
Yes, South Darenth is within the area we cover across London and the South East. A fixed quote usually follows within one working day of the survey details.
Who is the responsible person?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.
What should I send you?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
How long does ventilation cleaning take?
Typically, the work takes a shift or two for a small system, longer for a whole building. Large buildings can be phased, often out of hours, to fit around the building.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
Can we book visits on a schedule?
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.
Will we have to shut during the visit?
Not normally. The area we’re working in has to be out of use while we are there, so we book a time when it would be closed anyway.
What affects the quote in South Darenth
A fixed price needs a few facts first. We look at:
- How big the system is
- Site rules, permits and inductions
- Access, including roofs, risers and ceiling voids
- Travel, parking and unloading
What you pay depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.
What we need to know
To speed up the quote, please include:
- When the site is open and when it’s quiet
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Wide pictures of the system and the area around it
- Where the site is and what kind of site it is

When it’s something else
Not every problem is solved by ventilation duct cleaning, and we’d rather say so up front. It doesn’t solve:
- Kitchen extract ductwork, which needs a TR19® Grease clean
- Damaged ductwork beyond cleaning
- Damp or mould problems coming from the building fabric
If you’re not sure, just give us a ring on 0345 646 2711, or email photos and we will give you a straight answer before booking.
Where we work
- Toilet extract systems
- General extract ductwork
- Supply ductwork
- Grilles and diffusers
- Hospitals and care homes
- Offices and schools
Multi-site and managed buildings
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
Facilities teams in offices, schools and healthcare sites book us too across Kent. Work can be phased by floor, building or site to keep disruption down.
How it works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the ventilation duct cleaning, clear away and leave you the report. On site, the work takes a weekend for a modest system, with large buildings phased floor by floor. Visits to a village like South Darenth are booked in advance, at a time that suits whoever runs the site.
- We survey the system from drawings, pictures or a site visit.
- Ducts are inspected at access points and the condition recorded.
- Floors and furniture are covered and the ventilation turned off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Before we arrive
- Agree a time when the area can be out of use
- Arrange a key holder or contact on site
- Mention any parking or loading restrictions
Ask for a quote
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To start, give us a ring on 0345 646 2711 or email us.

What your team can do, and what needs us
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.
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 grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
