Around St John's, access is normally simpler than in a town centre, though gates and roof access are worth mentioning.
- We look at the system and any earlier reports.
- 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.
- We report on the work, listing any inaccessible sections and the next inspection date.

Ventilation duct cleaning in St John's
Everyone in the building breathes the air the ventilation brings in. Clean ducts are part of a healthy building, as much as clean filters and a well-kept AHU. If you are dealing with ductwork that hasn’t been inspected and musty smells from the ventilation, we can help, from hospitals and care homes, supply ductwork and offices and schools onwards.
Visits to a place like St John's are fitted around opening hours. The method doesn’t change: inspect first, clean, then record what was done.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

A few issues sit outside what this work can do:
- Building management settings that run the plant
- Ventilation that is undersized for the building

What your team can do, and what needs us
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.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
St John's questions
Will you come out to St John's?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Do you work overnight in St John's?
Yes, evening, overnight and weekend work is normal for us. It means the site in St John's keeps running as normal. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you have a 24/7 line?
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.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Will we have to shut during the visit?
Usually not. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits to keep things running.
Will we have paperwork to show the system was cleaned?
Yes. You get a certificate with the date, location and technician, plus a photo report.
Will you clean the vents in the rooms?
Yes. Where they can be removed, they’re taken down, cleaned and refitted. The rest are cleaned where they are.
Is TR19 cleaning required by law?
Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.
Common problems we fix in St John's
Building work is one of the biggest sources of debris in ducts, especially when the system runs during the work. That dust can stay in the ducts long after the builders leave.
It’s time to book a visit if you see:
- Rooms that feel airless when the system runs
- Odours carried round the building by the ducts
- Extract ducts clogged with lint and dust
- Dust marks around grilles and ceiling diffusers
Classrooms and halls at schools such as The Winston Churchill School A Specialist Sports College are easiest to work in when pupils are away.
Questions to ask before you book
- Whether VAT is included
- Proof of insurance
- How they set the interval to the next visit
- Which accreditations they hold, and whether you can check them
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare across Surrey. Work can be phased by floor, building or site to keep disruption down.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.

Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Tell your facilities team about dirty diffusers
- Stick to the filter change schedule
- Include grilles in the cleaning rota
- Do not run the ventilation while builders are sanding or cutting
Before any works, think about the ducts. Turn off the system or cover the openings during dusty jobs.
Protect the system during building work by turning it off or covering the openings.
Why act early in St John's
Clean ducts let the air move as designed, which takes strain off the fans. Dirty ducts make the whole system work harder. It’s easy to lose track of when the work was last done on a quieter site.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.
