Do you need ductwork cleaning in Telegraph Hill?
Damaged or poorly fitted filters let more grease into the duct. The duct then takes grease that the filters should have stopped, and build-up speeds up.
Any of these means the system needs a check-up:
- Stale grease odours from the duct
- Years of grease along the duct floor
- Duct runs that can’t be reached
- A duct clean needed for an insurer
Volunteers running a hall kitchen near St Catherine's Hatcham, or anywhere in Telegraph Hill, may not know when the extract was last cleaned, and a grease test settles it.

Ductwork cleaning in Telegraph Hill
If the ducts in Telegraph Hill haven’t been cleaned for a while, or nobody is sure when they were? A few details about the system are a good start when you phone us on 0345 646 2711 or use the quote form, and we’ll give you a fixed quote for ductwork cleaning, normally within one working day. We are often asked to deal with thick deposits at the bottom of a vertical duct and a duct nobody has opened in years, on multi-storey ducts, bends and junctions and vertical risers.
Kitchens in Telegraph Hill, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Telegraph Hill: your questions answered
Can the work in Telegraph Hill be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. That way a site in Telegraph Hill does not have to lose a day’s trading. Just call us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Do you clean school canteen extracts around Telegraph Hill out of term?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 76 schools and colleges with food registrations within roughly a mile and a half of Telegraph Hill. Booking early in the term gives the best choice of holiday dates.
What do you do with what you remove?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
Do you install duct access panels?
Yes, we do. We will point out where panels are needed, and we can fit them so those sections are cleaned in future.
Does the law say we must follow TR19?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
How long does it take to clean extract ducts?
Allow a shift or more, depending on the length of the runs and the number of access points. We will 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.
What should I send you?
A short description and a few photos, with the address and opening hours. If we need more, we will ask.
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Keep your cleaning records together
- Consider fitting panels where the report shows gaps
- Keep the fan on while anything is cooking
- Make sure filters are seated properly
After the clean, the same points are tested again, so the report shows the before and after figures. Photos of each section go alongside them.
Some signs mean the duct needs attention sooner: grease leaking from duct joints, smells, or a fan that sounds rough. Testing will show whether any section has reached 500 microns.
Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
What happens if it’s left?
Dealing with the ductwork in Telegraph Hill now beats dealing with it after a problem. It takes a shift or more, depending on the length of the runs and the number of access points, done out of hours so the kitchen keeps cooking. Planning ahead in Telegraph Hill lets you pick a quiet night rather than lose a busy one.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711, or email photos for straight advice and a fixed quote.

Behind every canopy among them is a run of ductwork that collects grease out of sight. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.

Part by part
Access panels
Extra panels can be installed where there are gaps, making future cleans more complete. We will recommend where they should go.
Vertical risers
Risers often pass through floors and walls, so fire dampers may be fitted where it crosses them. We test those as a separate job.
