Windsor and Maidenhead · Ventilation duct cleaning
Dedworth ventilation duct cleaning
Ventilation duct cleaning for commercial sites in Dedworth and across Windsor and Maidenhead. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Grilles and diffusers streaked with dirt
- Ductwork that hasn’t been inspected
- Odours carried round the building by the ducts
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Stick to the filter change schedule
- Keep vents and grilles clear of shelving and stock
- Report dust blowing from grilles straight away
- Watch for water stains around grilles
A TR19® certificate and photo report follow every clean. Keep them in the maintenance log, with the date, location and technician recorded.
Regular inspection is the core of TR19® Air. Inspecting on a schedule catches build-up before it becomes a big clean.
How we handle ventilation duct cleaning in Dedworth
Dust in ventilation ductwork isn’t only a cleanliness issue. It slows the air, strains the fans and can be blown back out of the grilles. A clean puts the system back as it should be. If you have dirty diffusers dropping dust into rooms and systems missing access panels, we can help, from hospitals and care homes, toilet extract systems and supply ductwork onwards.
In a smaller place like Dedworth, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Ventilation in Dedworth buildings
Food Standards Agency data includes about 23 schools, colleges and universities, about 9 hospitals, care homes and childcare premises and about 9 hotels and guest houses in Dedworth and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 1.5 miles east of Dedworth is King Edward VII Hospital, the nearest hospital. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. Dedworth, about 24 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you.
Classrooms and halls at schools such as Dedworth Green First School are easiest to work in when pupils are away.

Dedworth questions
Do you work at weekends in Dedworth?
Yes, out-of-hours work is a big part of what we do. It means the site in Dedworth keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Can you get to a site in Dedworth?
Yes, Dedworth is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you clean grilles and diffusers?
Yes. Removable grilles come down for cleaning and go back up. Fixed ones are cleaned in place.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Is TR19 a legal requirement?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Who is responsible for fire safety on the premises?
In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.
How much notice should we give?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Common problems we fix in Dedworth
Filters never catch everything, and that fine dust settles along the supply ducts. Extract ducts pick up dust, fibres and fluff from the rooms they serve.
It’s time to book a visit if you see:
- Rooms that feel airless when the system runs
- Ventilation that needs a TR19® Air inspection
- Damp or stale smells from grilles
- Toilet and washroom extracts full of fluff
King Edward VII Hospital, about 1.5 miles east, is the nearest hospital to Dedworth, and healthcare sites of every size need their supply air kept clean.
Questions to ask before booking
- When they can work, and whether that’s outside your opening hours
- When the next visit should be, and why
- Whether a survey comes first
- Whether a written report and pictures are included
Leave it or put it right?
Facilities teams are regularly asked to show evidence of ventilation hygiene. Having a recent certificate and photo report for a building in Dedworth answers the question. Around Dedworth, a kitchen or building out of action is missed right away.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before work begins.

- Dust and debris are removed from ducts, grilles and diffusers.
