Ventilation duct cleaning in Cold Harbour
Ventilation duct cleaning is something we carry out for buildings in Cold Harbour and right across Windsor and Maidenhead, in offices, schools, healthcare buildings and retail. Each building gets a survey first and a fixed quote. The work covers toilet extract systems, general extract ductwork and hospitals and care homes, and the jobs we see most are ductwork never cleaned since it was installed and ductwork with too few access panels to clean.
For a building in or near Cold Harbour, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Leaking or broken duct sections
- Kitchen extract ductwork, which needs a TR19® Grease clean
- A system that is not designed to move enough air
If you’re not sure, just call us on 0345 646 2711 or email us and we will give you a straight answer before booking.

How the job changes from site to site
Supply ductwork
Dust in supply ducts can be blown straight into occupied rooms. Cleaning it deals with the source.
Extract ductwork
Toilet and washroom extract can carry moisture as well as dust, so the dust tends to cling. They’re cleaned and their condition recorded.
How the visit works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a day or less for a small system and a series of visits for a large one. Somewhere as small as Cold Harbour, the date and timings are agreed with you well before the day.
- We look at the system and any earlier reports.
- We inspect the ducts at chosen points to see where cleaning is needed.
- The work area is protected and the system switched off.
- We clean the system and remove the debris from site.
- The report records what was cleaned, anything not reached and a next inspection date.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Let us know about parking and loading
- Move anything stored near the system

Why deal with it now?
Dust in ducts does not go away on its own. The longer it’s left, the more there is to remove, and the more gets blown back into the rooms. Rural sites can’t always move to another kitchen or room when something fails.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.

Your questions about ventilation duct cleaning in Cold Harbour
Do you work in villages like Cold Harbour?
Yes. Villages and rural sites across the South East are part of our work, Cold Harbour included. The journey is planned ahead, so a few details about the route help.
Do you work at weekends in Cold Harbour?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Who is the responsible person?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
Do we lose a day’s trading?
Not usually. The area we are working in has to be out of use while we are there, so the visit goes in a quiet slot.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
How much does ventilation duct cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.
Is a quote from pictures possible?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
In-house cleaning or a specialist?
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, next to our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Flag any dust coming out of the vents
- Protect the system from construction dust
- Diary the next TR19® Air inspection
- Keep filters changed on time
Pass the paperwork to your facilities or maintenance team, so the history stays together. Year on year, it shows how fast dust builds up.
Fit access panels where the ductwork cannot be reached. Hidden sections are the ones that get worst.
