Signs you need ventilation duct cleaning in Dorking
Planned maintenance tends to focus on fans and filters, not the ducts. A building in Dorking can have well-serviced plant and dirty ductwork at the same time.
Common reasons sites call us include:
- Toilet and washroom extracts full of fluff
- Ductwork never cleaned since it was installed
- Systems missing access panels
- Ventilation that needs a TR19® Air inspection
Workplaces around Dorking Deepdene station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

About our ventilation duct cleaning in Dorking
Toilet, washroom and general extract ducts gather dust, fluff and debris. Supply ducts pick up whatever gets past the filters. Both are cleaned, with the area protected and the mess contained. If you are dealing with dirty diffusers dropping dust into rooms and odours carried round the building by the ducts, we can put it right, from supply ductwork, offices and schools and general extract ductwork onwards.
Buildings in towns like Dorking often have ventilation added in stages, with units on the roof or in a plant room. The work starts with an inspection to decide what needs cleaning, so you’re not paying for more than the system needs.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Common questions in Dorking
Do you work at weekends in Dorking?
Yes. We work evenings, overnight and at weekends. That way a site in Dorking doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we’ll book within them.
Can ventilation in schools around Dorking be cleaned out of term?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Dorking. Just give us a ring on 0345 646 2711, or send details by email with your term dates and we will plan around them.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
What information do you need?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.

Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Is Dorking in your area?
Yes. Our technicians work in Dorking, within the South East and London area we cover.
What affects the quote in Dorking
The quote reflects the site in front of us. We consider:
- One-off work versus a regular cycle
- The number of sites or systems
- How big the system is
- Site rules, permits and inductions
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.
Asking for a quote
We can often survey from pictures. The most useful are:
- Detail shots of panels, filters and grilles
- Where the site is and what kind of site it is
- The times we could work without disrupting the site
- Any previous report or certificate
To help us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or email photos.
Between visits
After the visit, a few habits help the work last:
- Wipe grilles and diffusers during routine cleaning
- Flag any dust coming out of the vents
- Log every filter change
- Protect the system from construction dust
What was cleaned is listed, along with any parts that weren’t accessible, with photos before and after. If access panels are needed, we will say where.
Fix leaks and damp near the ductwork quickly, as moisture makes dust stick.
What ventilation duct cleaning cannot fix
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Ventilation that’s undersized for the building
- Ducts that are damaged, corroded or leaking and need replacing
- Building management settings that run the plant
If in doubt, call 0345 646 2711 or drop us a line and we will say what we think.
Where we work
- General extract ductwork
- Hospitals and care homes
- Toilet extract systems
- Supply ductwork
- Grilles and diffusers
- Offices and schools
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes from one overnight visit to a phased programme over several weeks. Work in Dorking is usually booked after closing, early in the morning or on a closed day.
- First we check the layout and any past paperwork.
- Inspection points are chosen and the ducts examined.
- We cover the area below and turn off the system.
- Ducts, grilles and diffusers are cleaned and the debris taken away.

Why deal with it now?
If a building in Dorking has just been refitted, now is the time to clean the ductwork. Otherwise construction dust left in the ducts is blown out once the system runs. With a fire risk assessment or inspection due, getting the work done first puts you on the front foot.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
