Greater London · Ventilation duct cleaning
Ventilation cleaning in Lewisham
Professional ventilation duct cleaning in and around Lewisham, booked around your opening hours and finished with a written report and photos.
- Supply ducts with years of dust inside
- Dirty diffusers dropping dust into rooms
- Toilet and washroom extracts full of fluff
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Report leaks or damp near ceilings and risers
- Do not block grilles with furniture or storage
- Include grilles in the cleaning rota
- Protect the system from construction dust
Pass the paperwork to your facilities or maintenance team, so it’s all in one place. Over time, it shows how quickly the system gets dirty.
Regular inspection is the core of TR19® Air. Scheduled inspections spot dust before it becomes a major job.
Ventilation duct cleaning in Lewisham
Every ventilation system has ducts bringing air in and ducts taking it out. Over time, both collect dust and debris, some of which ends up back in the rooms. Our cleaning covers the ducts, grilles and diffusers, to TR19® Air. We’re often asked to deal with systems with no record of inspection or cleaning and construction dust left in ducts after a refit, across supply ductwork, offices and schools and toilet extract systems.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Lewisham is typically planned out of hours. Parking and loading are agreed with the building in advance.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, which takes anything from a single shift for a small office to a planned programme of nights for a large building. Night and weekend working is normal for us in London, and a site in Lewisham is no exception.
- We survey the system from drawings, pictures or a site visit.
- We inspect inside the ductwork at set points and photograph it.
- We protect the rooms beneath and switch the system off.
- We clean the ductwork, grilles and diffusers through access panels.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Plan for cooking equipment or plant to be off before we arrive
- Name a contact who can let us in at the agreed time
Ask for a quote
Getting a quote doesn’t take long. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

For Lewisham, the closest hospital is University Hospital Lewisham, roughly 0.6 miles south-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
For schools like St Saviour's Catholic Primary School, the holidays are the usual time to inspect and clean ventilation. Healthcare buildings such as University Hospital Lewisham, about 0.6 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Lewisham, yours matters too.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

Why deal with it now?
Leave dust in the ductwork and it keeps building. The longer it’s left, the more there is to remove, and the more gets blown back into the rooms. Leaving it on a busy London site only adds to the work.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, give us a ring on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

Signs you need ventilation duct cleaning in Lewisham
It matters for the people inside: dirt in the ducts can come back out of the grilles, slow the air and add strain on fans. In hospitals, care homes and schools, clean air is especially important.
The symptoms we’re asked about most include:
- Toilet and washroom extracts full of fluff
- Duct runs that cannot be reached for cleaning
- Damp or stale smells from grilles
- Stuffy rooms and stale air
If you run an office near Lewisham station, its supply ductwork can gather dust for years before anyone looks inside.

Questions from Lewisham
Do you work at weekends in Lewisham?
Yes, out-of-hours work is a big part of what we do. The work in Lewisham can fit around your hours. When you phone us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Can a school’s ventilation in Lewisham be done out of term time?
Yes, holiday work suits schools best. With about 48 schools and colleges on the FSA’s register within roughly a mile and a half of Lewisham, it pays to plan holiday dates ahead. Just phone us on 0345 646 2711 or email us with your term dates and we will plan around them.
Do you look at the system first?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
When should our ventilation next be cleaned?
Under TR19® Air, the answer comes from inspecting the ducts. Busy or sensitive buildings may need it more often.
Is Lewisham in your area?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Lewisham included.
How long does ventilation cleaning take?
It takes a day or less for a small system and a series of visits for a large one. How much ductwork there is and how easily it’s reached decide the rest.
What affects the cost of ventilation duct cleaning
We quote each job individually. This is what makes a difference:
- How many systems or sites are involved
- The condition of the system
- How easy every part is to reach
- Where the site is and how we reach it
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
When you contact us, it’s useful to have:
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Close-ups of filters, grilles, hatches or access panels
