About our ventilation duct cleaning in Carpenders Park
Everyone in the building breathes the air the ventilation brings in. Keeping the ducts clean is a sensible part of looking after them, alongside filter changes and AHU maintenance. We’re often asked to deal with ductwork that hasn’t been inspected and grilles and diffusers streaked with dirt, on grilles and diffusers, hospitals and care homes and general extract ductwork.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Carpenders Park is usually planned out of hours. Loading and parking are planned with the building first.
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, and we are fully insured.

Carpenders Park questions
Can the work in Carpenders Park be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Can a school’s ventilation in Carpenders Park be done out of term time?
Yes. The holidays are the usual time for school work. With about 11 schools and colleges on the FSA’s register within roughly a mile and a half of Carpenders Park, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you inspect before cleaning?
Yes. Every job is surveyed first, from pictures, drawings or a site visit, and then quote a fixed price.
What is TR19® Air?
It’s BESA’s guidance for ventilation hygiene in general supply and extract systems, rather than kitchen extract. It’s risk-based and led by inspection, and kitchen extract falls under TR19® Grease.
Do we lose a day’s trading?
Not usually. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.

Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.

What a clean will not put right

- Building management settings that run the plant
- A system that isn’t designed to move enough air
If you’re not sure, just call us on 0345 646 2711, or send details by email and we will give you a straight answer.
What the work covers

How it works
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. In Carpenders Park, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- 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.
- 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.
How to prepare
- Move anything stored near the system
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids

Related advice
In-house cleaning or 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.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
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.
Grilles and diffusers
Grilles and diffusers are where the ducts meet the room. They’re cleaned along with the ductwork, so dust on them is not blown back in.
Why it’s worth doing now in Carpenders Park
Smells, dust around grilles and stuffy rooms are signs the system needs attention. Acting early keeps the clean simpler. In Carpenders Park, as across London, ductwork often passes through shared risers and other people’s space.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.
