What happens if it’s left?
Starting with an inspection means you only clean what needs it. Putting the inspection off just means you do not know where you stand. Out of sight is the usual reason a rural system goes too long without attention.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before work begins.

About our ventilation duct cleaning in Colnbrook
When the work is finished, you get a TR19® certificate and before and after photos. 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 are often asked to deal with construction dust left in ducts after a refit and ductwork that hasn’t been inspected, across toilet extract systems, hospitals and care homes and general extract ductwork.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What affects the quote in Colnbrook
You’ll get a fixed price before any work starts. It takes into account:
- Site rules, permits and inductions
- The times the site is available
- One-off work versus a regular cycle
- How easy every part is to reach
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
Helping us quote
We can often survey from pictures. The most useful are:
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then send you a fixed quote. To start, call us on 0345 646 2711, or email photos.
Ventilation duct cleaning in Colnbrook: local notes

Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 19 miles out from central London, Colnbrook is part of the South East area we work across. Evening, overnight and weekend visits are all possible. The nearest hospital to Colnbrook is Upton Hospital, about 3.2 miles north-west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Hospitals such as Upton Hospital (about 3.2 miles north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Colnbrook are no different. Wherever a school like Colnbrook Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Questions from Colnbrook
Can you do ventilation duct cleaning in Colnbrook?
Yes, Colnbrook is within the area we cover across London and the South East. Get in touch with the details and we will arrange a survey.
Do you work overnight in Colnbrook?
Yes, out-of-hours work is a big part of what we do. That way a site in Colnbrook doesn’t have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Will we have paperwork to show the system was cleaned?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
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 you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. At the end, the area is cleaned down.
Staff cleaning versus specialist work
Staff cleaning doesn’t 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.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.

Multi-site and managed buildings
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
We also work for facilities teams across offices, schools and healthcare across Slough. Larger estates can be phased building by building to keep disruption down.
How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes from one overnight visit to a phased programme over several weeks. For a village or hamlet like Colnbrook, tell us about narrow lanes, gates and parking when you book.
- First we plan when the work can happen, often out of hours.
- Access panels are opened along each run.
- Before pictures are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- After photos are taken and the certificate and report issued.
Getting ready for the visit
- Clear loose items from the work area
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any sign-in, permit or induction we need
How to get a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
