- Blocked general extract ductwork
What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Day-to-day cleaning is something your team can do: 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, which is where we come in.
Ventilation duct cleaning in Lessness Heath, done properly
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. Cleaning restores the clear airway the system was designed with. The work covers grilles and diffusers, offices and schools and general extract ductwork, and people most often call us about duct runs that can’t be reached for cleaning and ducts that need a clean before handover.
London buildings tend to keep their plant on the roof or below ground, so work in Lessness Heath is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
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.

Lessness Heath buildings and their air
Food Standards Agency records list about 29 schools, colleges and universities and about 62 care, childcare and hospital premises registered as food businesses within 1.5 miles or so of the middle of Lessness Heath. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. About 0.9 miles south-east of Lessness Heath is Erith and District Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
School buildings such as Lessness Heath Primary School are typically done in the holidays, so classrooms aren’t disturbed. If you run an office near Belvedere station, its supply ductwork can gather dust for years before anyone looks inside.

What else we do in Lessness Heath
What affects the cost of ventilation duct cleaning
We do not publish a price list, because no two systems are the same. The quote depends on:
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
- Travel, parking and unloading
- Any permits to work or inductions
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’ll explain each part.
Asking for a quote
Before you ask for a quote, gather:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it

Lessness Heath: your questions answered
Do you work at weekends in Lessness Heath?
Yes, nights and weekends are routine for us. That way a site in Lessness Heath does not have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
How do you handle parking and loading in Lessness Heath?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
Do we need to close while you work?
Not typically. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
Who is responsible for fire safety on the premises?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
What about areas you can’t get to?
We record them on the report, with pictures where possible, and we tell you what would make it reachable, for example new access panels.
Do you cover Lessness Heath?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Lessness Heath included.
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Switch the ventilation off or cover grilles during dusty building work
- Tell your facilities team about dirty diffusers
- Keep vents and grilles clear of shelving and stock
- Get leaks near ductwork fixed quickly
Before any works, think about the ducts. Switch it off or cover the grilles while dusty work goes on.
Good filter maintenance protects the ductwork. Overdue or badly fitted filters let dust into the supply ducts.
What we do, step by step
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes a day or less for a small system and a series of visits for a large one. Night and weekend working is normal for us in London, and a site in Lessness Heath is no exception.
- First we plan when the work can happen, often out of hours.
- Access panels are opened along each run.
- We photograph the ducts, then clean each section in turn.
- We clean the grilles and diffusers and put them back.
- We take after pictures and send the certificate and report.
Before we arrive
- Arrange a key holder or contact on site
- Clear the space around the work
- Mention any parking or loading restrictions
Getting a quote
Getting a quote doesn’t take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Advice
Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Different parts, different methods
Extract ductwork
Extract ducts take air out of toilets, washrooms and general areas. They collect dust, lint and fibres and restrict the flow over time.
Grilles and diffusers
Dark streaks round a ceiling diffuser can be a sign of dirty supply air. We clean the grilles and look at what’s behind them.
