About our ventilation duct cleaning in Knowl Hill
Ventilation duct cleaning is something we carry out for buildings in Knowl Hill and right across Wokingham, from offices and schools to hospitals, care homes and shops. Each building gets a survey first and a fixed quote. The work covers supply ductwork, general extract ductwork and offices and schools, and common reasons people get in touch are poor airflow from the vents and systems missing access panels.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What the work involves, part by part
Grilles and diffusers
Every duct ends at a grille or diffuser in the room. We clean them as part of the job, so the room side matches the duct side.
Supply ductwork
Dust in supply ducts can be blown straight into occupied rooms. Cleaning it deals with the source.
Looking after it afterwards
Results last longer with the right care. We suggest:
- Keep to the inspection interval in your report
- Log every filter change
- Flag any dust coming out of the vents
- Keep the TR19 certificate and photo report in the maintenance log
Change filters on schedule so the clean ducts stay clean. Overdue filters let dust straight back in.
Good filter maintenance protects the ductwork. Overloaded or poorly seated filters let dust straight through.
What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
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.
How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. 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. Visits to a village like Knowl Hill are booked in advance, at a time that suits whoever runs the site.
- First we check the layout and any past paperwork.
- We inspect the ducts at chosen points to see where cleaning is needed.
- We cover the area below and turn off the system.
- We clean the system and remove the debris from site.
- We report on the work, listing any inaccessible sections and the next inspection date.
Before we arrive
- Agree a time when the area can be out of use
- Plan for cooking equipment or plant to be off before we arrive
- Clear loose items from the work area

Managing agents and facilities teams in Knowl Hill
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
We also work for facilities teams across offices, schools and healthcare across Wokingham. Larger estates can be phased building by building around the people who use them.
What happens if it’s left?
Landlords, tenants and auditors may want proof the ventilation is looked after. A TR19® certificate and photo report from a recent clean give them that. With notice, the visit to Knowl Hill can be fitted around your bookings and events.
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 will explain each part.
