Ventilation duct cleaning in Mitcham
Supply ducts carry air into the rooms and extract ducts take it away. Over time, both collect dust and debris, some of which ends up back in the rooms. We clean the ductwork, grilles and diffusers to TR19® Air. Typical jobs include ventilation full of debris from building work and systems missing access panels, on hospitals and care homes, toilet extract systems and grilles and diffusers.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Mitcham is usually planned out of hours. Parking and loading are agreed with the building in advance.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Mitcham questions
Can ventilation in schools around Mitcham be cleaned out of term?
Yes, holiday work suits schools best. The FSA’s register shows about 30 schools and colleges with food registrations within roughly a mile and a half of Mitcham. Just ring 0345 646 2711 or drop us a line with your term dates and we will plan around them.
How do you handle parking and loading in Mitcham?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we will book into it.
Can you price the work without visiting?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Do you survey before quoting?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.
Do we need to close while you work?
Not normally. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
When should our ventilation next be cleaned?
Inspection should decide it, in line with TR19® Air. Heavily used buildings, or those with vulnerable occupants, may need attention more often.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.

What happens on the day
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes a day or less for a small system and a series of visits for a large one. For a job in Mitcham, tell us about loading bays, permits, lifts and roof access when you book.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- We photograph the ducts, then clean each section in turn.

Advice
What ventilation duct cleaning can’t fix
To be straight with you, some problems need a different fix:
- Design problems with the ductwork layout
- Kitchen extract ductwork, which needs a TR19® Grease clean
- Leaking or broken duct sections
Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we’ll tell you honestly before you book.
Where we work
- General extract ductwork
- Hospitals and care homes
- Supply ductwork
- Offices and schools
- Grilles and diffusers
- Toilet extract systems
Aftercare tips
So the system stays in good health:
- Wipe grilles and diffusers during routine cleaning
- Switch the ventilation off or cover grilles during dusty building work
- Make sure nothing is stacked against extract grilles
- Get leaks near ductwork fixed quickly
If there’s building work planned, protect the ventilation. Switch it off or cover the grilles while dusty work goes on.
Make sure there are enough access panels to inspect and clean the ducts. Hidden sections are the ones that get worst.

Common problems we fix in Mitcham
Planned maintenance tends to focus on fans and filters, not the ducts. A building in Mitcham can have well-serviced plant and dirty ductwork at the same time.
Any of these means the system needs a check-up:
- Poor airflow from the vents
- Blocked general extract ductwork
- Ventilation full of debris from building work
- Odours carried round the building by the ducts
For schools like St Thomas of Canterbury Catholic Primary School, the holidays are the usual time to inspect and clean ventilation.
Before you book anyone
- What paperwork you get at the end
- Whether the work can be done while the site is closed
- Proof of insurance
- Proof of accreditation you can verify
What happens if it’s left?
A clean system moves air more easily, which takes strain off the fans. Leaving them means the plant works harder for the same result. A busy site in Mitcham builds up dirt and wear quickly, so putting it off makes the eventual job larger.
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’ll go through it with you.
