Ventilation duct cleaning in Winchmore Hill
When the work is finished, you get a TR19® certificate and before and after pictures. 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. The work covers general extract ductwork, toilet extract systems and grilles and diffusers, and the jobs we see most are ventilation full of debris from building work and dirty diffusers dropping dust into rooms.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Winchmore Hill, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
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.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Get leaks near ductwork fixed quickly
- Log every filter change
- Switch the ventilation off or cover grilles during dusty building work
- Store cleaning certificates where auditors can find them
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.
Keep filters changed on time. Overloaded or poorly seated filters let dust straight through.
Do you need ventilation duct cleaning in Winchmore Hill?
Planned maintenance tends to focus on fans and filters, not the ducts. A building in Winchmore Hill can have well-serviced plant and dirty ductwork at the same time.
Signs it’s time to call us include:
- Supply ducts with years of dust inside
- Ventilation full of debris from building work
- Systems with no record of inspection or cleaning
- Poor airflow from the vents
School buildings such as St. Paul's School are normally done in the holidays, so classrooms aren’t disturbed.
Questions to ask before booking
- Whether the whole system is included, or only the parts that are easy to reach
- What happens if part of the system cannot be accessed
- Which accreditations they hold, and whether you can check them
- Whether they’re fully insured
Managing agents and facilities teams in Winchmore Hill
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Facilities teams in offices, schools and healthcare sites book us too in Winchmore Hill and across Greater London. Larger estates can be phased building by building to keep disruption down.
How the visit works
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes anything from a single shift for a small office to a planned programme of nights for a large building. Loading bays, visitor permits and roof access are the first things we ask about for a site in Winchmore Hill.
- First the system is surveyed, on site or from photos and drawings.
- Inspection comes next, with photos of the inside of the ducts.
- Floors and furniture are covered and the ventilation turned off.
- Dust and debris are removed from ducts, grilles and diffusers.
- You get a TR19® certificate and photo report, with any unreached sections noted.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
Ask for a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Fixed quotes for ventilation duct cleaning in Winchmore Hill
There’s no set price list, because no two systems are the same. The quote depends on:
- Travel, parking and unloading
- The scale of the work
- The condition of the system
- The times the site is available
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711 or send us an email, and we’ll explain what it covers.
What we need to know
There’s no need for technical detail. It helps if you can send:
- A few general shots of the system
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
- Any access panels or hatches you can see
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Part by part
Supply ductwork
Anything in a supply duct can end up in the rooms it feeds. We clean the runs so it isn’t blown back in.
Hospitals and care homes
Dust control matters during work in occupied care settings. We protect the work area and take everything away.
Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. 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.
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. Leave those to us.
