Ventilation duct cleaning in Roe Green
Supply ducts carry air into the rooms and extract ducts take it away. Over time, both collect dust and debris, some of which ends up back in the rooms. We clean the ductwork, grilles and diffusers to TR19® Air. The work covers general extract ductwork, toilet extract systems and supply ductwork, and common reasons people get in touch are musty smells from the ventilation and ventilation full of debris from building work.
In a village or hamlet like Roe Green, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Roe Green: your questions answered
Can the work in Roe Green be done at night or at weekends?
Yes, we can come after you close and finish before you open. That way a site in Roe Green doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Is Roe Green within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Roe Green included. A survey first, from pictures or a visit, means we arrive with the right kit.
How long does ventilation cleaning take?
Typically, the work takes a weekend for a modest system, with large buildings phased floor by floor. Large buildings can be phased, often out of hours, to fit around the building.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. We typically quote within one working day, and there’s a 24/7 line for emergencies.
What happens if parts of the ductwork cannot be reached?
Those sections are recorded as not cleaned in the report, so it’s clear what’s outstanding. We can fit new access panels so they’re covered next time.
Can you price the work without visiting?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.

What affects the cost of ventilation duct cleaning
Your quote is based on your site. We take into account:
- Any permits to work or inductions
- Where the site is and how we reach it
- Whether several sites go on one quote
- Access, including roofs, risers and ceiling voids
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before any work starts.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Problems your staff have spotted
- When the site is open and when it’s quiet
- The postcode and the type of business
- Any previous report or certificate
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 work begins.
What happens on the day
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, tidy up and leave you the report. On site, the work takes a shift or two for a small system, longer for a whole building. If the van will struggle with a lane or gateway near Roe Green, let us know and we will plan around it.
- We survey the system from drawings, pictures or a site visit.
- We inspect inside the ductwork at set points and photograph it.
- The area below is protected and the system switched off.
- We clean the ductwork, grilles and diffusers through access panels.
- A certificate and before and after pictures follow, with anything not reached recorded.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
- Arrange a key holder or contact on site
How to get a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, give us a ring on 0345 646 2711 or use the quote form.
Advice
For landlords and multi-site operators
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.

What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Signs you need ventilation duct cleaning in Roe Green
Moisture in ducts makes dust stick. Condensation and leaks turn loose dust into a stubborn layer, and it becomes harder to remove.
If you notice any of these, it’s worth a diagnosis:
- Dusty supply ductwork that hasn’t been cleaned in years
- Grilles and diffusers streaked with dirt
- Duct runs that can’t be reached for cleaning
- Ductwork that hasn’t been inspected
School buildings such as Sandon Junior Mixed and Infant School are normally done in the holidays, so classrooms aren’t disturbed.
What to look for in a quote
- What paperwork you get at the end
- Whether they recommend a next date
- Whether they’re fully insured
- Whether the whole system is included, or only the parts that are easy to reach
What happens if it’s left?
Leave dust in the ductwork and it keeps building. Every year adds to the job, and the more gets blown back into the rooms. A fault that closes a site in a village like Roe Green affects everyone who depends on it.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Design problems with the ductwork layout
- Cooking extract ducts, which are a separate specialist clean
- Building management settings that run the plant
