Ductwork cleaning in Chislehurst
Ductwork in Chislehurst is cleaned the same thorough way as everywhere else we work: we test the grease first, remove thick deposits by hand and degrease what’s left. Post-clean readings and pictures complete the record. If you have ductwork that has never been cleaned and duct runs that can’t be reached, we can put it right, from attenuators, bends and junctions and multi-storey ducts onwards.
In a London area like Chislehurst, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
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, with full insurance on top.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: 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.
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.
Grease, kitchens and Chislehurst
The FSA’s food hygiene register includes about 13 pubs, bars and clubs within about 1.5 miles of central Chislehurst. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Chislehurst is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Environmental health officers from Bromley council inspect food businesses in Chislehurst. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
For kitchens close to Chislehurst station, where the day often starts early and ends late, the extract can be cleaned overnight. Where a hall near Parish Church The Annunciation Of Blessed Virgin Mary, or anywhere in Chislehurst, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Your questions about ductwork cleaning in Chislehurst
Can you come to Chislehurst after we close?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. When you call 0345 646 2711 or send us an email, mention when the site is quiet.
Does London parking affect a job in Chislehurst?
Tell us where a van can stop near your site in Chislehurst, and about any building rules on loading. Working overnight, as we often do in London, normally makes it simpler.
What information do you need?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we’ll ask.
How long does it take to clean extract ducts?
It takes a shift or more, depending on the length of the runs and the number of access points. We’ll confirm the time when we quote.
Do we lose a day’s trading?
Not normally. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What types of premises do you cover?
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.
What happens if it’s left?
BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean straight away. Putting off the clean only pushes readings higher. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too in Chislehurst and across Greater London. Work can be phased by floor, building or site around the people who use them.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
When to call us in Chislehurst
Grease in a duct running from a kitchen in Chislehurst is as much a fire risk as in any building. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
Look out for any of the following:
- Smells of old cooking grease from the ductwork
- Readings above 200 microns from a grease thickness test
- An insurer asking for TR19 evidence
- Fat dripping from the ductwork
School kitchens, at schools like Red Hill Primary School for example, are typically cleaned in the holidays so no lunches are lost.

How it works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes a few hours for a short run, longer for long runs and tall risers, and we clear up before we go. Getting kit into a London building takes planning, so let us know where we can load and park in Chislehurst.
- First we diagnose: the route, the access and the grease levels.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, pictures and a recommended next clean date complete the job.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know about parking and loading
- Dig out any earlier paperwork for the system
Get a fixed quote
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Book the next clean before the recommended date
- Keep the fan on while anything is cooking
- Do not block access panels with shelving or stock
- Check readings when the menu changes
Any section of duct we couldn’t reach is listed on the report and why. You can then decide whether to have access panels fitted.
Extra access panels mean more of the duct gets cleaned each time. It doesn’t stop grease forming, but it stops it building unseen.
How the job changes from site to site
Access panels
Every section of duct is cleaned through an access panel. Without them, parts of the duct cannot be reached and the report has to say so.
Vertical risers
Risers often pass through floors and walls, where fire dampers may be fitted. Damper testing is a separate service.
