About our ventilation duct cleaning in Fortis Green
Everyone in the building breathes the air the ventilation brings in. Clean ducts are part of a healthy building, alongside filter changes and AHU maintenance. The work covers general extract ductwork, offices and schools and grilles and diffusers, and people most often call us about dusty supply ductwork that hasn’t been cleaned in years and systems with no record of inspection or cleaning.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Fortis Green.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Switch the ventilation off or cover grilles during dusty building work
- Flag any dust coming out of the vents
- Log every filter change
- Diary the next TR19® Air inspection
We recommend when the system should next be inspected, based on what we found. Put it in the diary now so it is not missed.
Keep filters changed on time. Overdue or badly fitted filters let dust into the supply ducts.
Do you need ventilation duct cleaning in Fortis Green?
Ductwork is hidden above ceilings and in risers, so nobody sees the build-up. Grilles may be wiped, but the ducts behind them rarely are.
It’s time to book a visit if you see:
- Poor airflow from the vents
- Supply ducts with years of dust inside
- Damp or stale smells from grilles
- Construction dust left in ducts after a refit
If you manage a school such as Fortismere School, ventilation cleaning is best booked for the holidays.
Questions to ask before booking
- If they look at the system before pricing
- Whether a written report and photos are included
- When the next visit should be, and why
- Exactly which parts of the system are covered
Different parts, different methods
Hospitals and care homes
Dust control matters during work in occupied care settings. The area is protected, and debris contained and removed.
Schools and colleges
Holidays and weekends are the natural time to clean school ventilation, when classrooms are empty.
When something else is needed
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Damp or mould problems coming from the building fabric
- Ducts that are damaged, corroded or leaking and need replacing
- Design problems with the ductwork layout
Not sure which it is? You can ring 0345 646 2711 or use the quote form and we’ll tell you honestly.

How it 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 a weekend for a modest system, with large buildings phased floor by floor. Before any visit in Fortis Green, we agree where the van can stop and how equipment reaches the system.
- First the system is surveyed, on site or from pictures and drawings.
- We inspect inside the ductwork at set points and photograph it.
- The area below is protected and the system switched off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Preparing for the visit
- Arrange a key holder or contact on site
- Clear the space around the work
- Let us know when the site is closed or quiet

Fortis Green: your questions answered
Do you work overnight in Fortis Green?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Is parking a problem for work in Fortis Green?
Tell us where a van can stop near your site in Fortis Green, and about any building rules on loading. Much of our London work is done overnight, which helps.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Can you quote from photos?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Ventilation in Fortis Green buildings
Food Standards Agency data includes about 51 schools, colleges and universities and about 49 caring premises (care homes, nurseries and hospitals) in Fortis Green and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. In London, ventilation plant is often on the roof or below ground, so the work is normally done out of hours. About 0.7 miles north of Fortis Green is Coppetts Wood Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you run a surgery, dental practice or care home near Fortis Green, clean ventilation matters as much to you as to a hospital like Coppetts Wood Hospital (about 0.7 miles north).

Why deal with it now?
An inspection-led approach avoids cleaning ducts that do not need it. Skipping it leaves you guessing. A building in Fortis Green may have flats or offices above and alongside, and a fault in the system can affect them too.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, call us on 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.
