Ventilation duct cleaning in Knockholt
Everyone in the building breathes the air the ventilation brings in. Keeping the ducts clean is a sensible part of looking after them, as much as clean filters and a well-kept AHU. Typical jobs include grilles and diffusers streaked with dirt and blocked general extract ductwork, on grilles and diffusers, hospitals and care homes and offices and schools.
Work in a small place like Knockholt starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

When it’s something else
In fairness, there are a few things this work will not fix:
- Ducts that are damaged, corroded or leaking and need replacing
- Condensation caused by the building rather than the ducts
- Kitchen extract ductwork, which needs a TR19® Grease clean
If in doubt, call us on 0345 646 2711 or send us an email and we’ll say what we think.

Do you need ventilation duct cleaning in Knockholt?
Most ductwork is out of sight, so dust collects unseen. Grilles may be wiped, but the ducts behind them rarely are.
Most sites get in touch after spotting one of these:
- Systems missing access panels
- Ducts that need a clean before handover
- Supply ducts with years of dust inside
- Rooms that feel airless when the system runs
Orpington Hospital, about 3.6 miles north, is the nearest hospital to Knockholt, and healthcare sites of every size need their supply air kept clean.

It depends on the building, how the system is used and what inspection finds. Inspecting regularly shows when cleaning is needed.

Are you fully insured?

What we do, step by step
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a weekend for a modest system, with large buildings phased floor by floor, and we clear up before we go. We agree a date with you, plan the drive to Knockholt and turn up when the site is quiet.
- We look at the system and any earlier reports.
- We inspect the ducts at chosen points to see where cleaning is needed.
- We cover the area below and turn off the system.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- The report records what was cleaned, anything not reached and a next inspection date.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms
Getting 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 get going, ring 0345 646 2711 or drop us a line.
Advice
What affects the cost of ventilation duct cleaning
The survey tells us what the work involves. The main factors are:
- A single visit or a regular plan
- How easy every part is to reach
- Any permits to work or inductions
- Where the site is and how we reach it
You won’t find a price list here, 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
When you contact us, it’s useful to have:
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Multi-site and managed buildings
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.
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Store cleaning certificates where auditors can find them
- Report leaks or damp near ceilings and risers
- Keep filters changed on time
- Do not block grilles with furniture or storage
You get a TR19® certificate and a photo report after the clean. Keep them in the maintenance log, with the date, location and technician recorded.
TR19® Air works through regular inspection. Inspecting on a schedule catches build-up before it becomes a big clean.
What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
