Blackwood · TR19 Grease
We clean the full commercial duct run - grease, dry and laundry ductwork, canopy to roof fan - for kitchens, offices and industrial sites across Blackwood, and certify it to the TR19 Grease standard your insurer expects.
Blackwood
Blackwood rates hundreds of food premises, and behind a large share sits an extract duct a canopy clean never reaches - plus the dry ductwork and air-handling that keep its offices and public buildings running.
The city's kitchens sit in tight, mixed stock - Hall Street, Gordon Road, Oakdale - with long concealed duct runs up to roof fans. We clean the full run to the TR19 Grease standard, canopy to fan, including the horizontal and vertical sections a canopy-only clean leaves coated.
Beyond the kitchens, we clean the dry ductwork and air-handling in offices, schools and public buildings, and the lint-heavy laundry ducts in hotels and care homes. High-output kitchens - pub and hotel kitchens, workplace canteens, cafes and the busy town-centre takeaways - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Blackwood insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard works in grease-film thickness, fixing the depth at which a run must be cleaned and re-tested. In the shared roof voids around Hall Street and Oakdale, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Blackwood run through existing and newly cut inspection hatches, strip it to bare metal, log grease-depth readings at fixed points before and after, and issue a TR19 Grease certificate with the post-clean depths recorded.
By system
The fire risk. Fried-food extract coats duct walls in combustible grease; cleaned canopy to fan and certified to TR19 Grease.
Supply and general extract in offices and public buildings, carrying dust and debris that throttles airflow and loads the air-handling unit; cleaned to TR19.
The hidden one. Tumble-dryer ducting packs with lint - highly combustible - in Blackwood hotels, care homes and gyms.
On the ground in Blackwood
We are in Blackwood's ductwork and plant every week. The proof is the jobs, not the stock photos.
A popular Blackwood library had its fan coil unit and main supply runs laden with dust and debris after years without a clean. We ran rotary brushes and a negative-air machine through the branch runs, then fitted fresh supply filters. Air through the occupied areas came up noticeably fresher and the dust complaints stopped, and the client was really pleased. The site's resident cat kept a close eye on us from the top of the stairs.
When it is due
Ductwork rarely warns you politely. In a busy Blackwood kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Hall Street line, a rim of grease at the filters, or a Blackwood insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Gordon Road kitchen needs it far more often than a quiet cafe - and your certificate sets the date, so nothing is left to chance.
How it runs
Inspect the full Blackwood run, find the access gaps in the concealed sections, agree scope and frequency.
Fit inspection hatches where the run is sealed - common in the older Oakdale conversions - and protect the kitchen.
Canopy to roof fan, down to bare metal, with before-and-after grease-depth evidence.
TR19 Grease certificate, grease-depth record and next-due date for your Blackwood fire logbook.
Why it matters
Three duties push every Blackwood operator to keep ductwork clean, and they reinforce one another.
Fire safety law. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for a Blackwood premises must assess and manage fire risk. A grease-laden duct is one of the most serious risks in any catering building, because a flare-up on a Hall Street cookline can travel the ductwork and spread fire through concealed voids. The Health and Safety at Work etc. Act 1974 and the HSE reinforce the same duty of care.
Insurance. A current TR19 Grease certificate is the evidence your Blackwood insurer expects. Without it, a fire claim can be reduced or refused outright - an expensive gap to find after the event.
Hygiene and environmental health. When Caerphilly County Borough Council carries out a food hygiene inspection it judges the physical state of the premises, and ventilation is part of that. A grease-choked extract can pull down the rating an Environmental Health Officer gives, on top of the odour and the weakening airflow your staff put up with.
It is set by cooking hours under TR19 Grease - roughly every three months for heavy use of 12 to 16 hours a day, every six for moderate, every twelve for light. A hard-frying Hall Street kitchen sits in a tighter band than a daytime Gordon Road cafe. We measure the grease load and confirm your interval.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Hall Street operator's insurer and fire risk assessor expect.
The full run, canopy through the concealed horizontal and vertical ductwork to the roof fan - the hidden sections a canopy-only clean leaves loaded, which matters in the tight stock around Hall Street and Oakdale where the runs are long and awkward.
Little, if it is planned. We survey the Blackwood run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Gordon Road cookline is back in service for the next shift.
Yes. We clean the dry ductwork and air-handling in Blackwood offices, schools and public buildings, and the lint-heavy laundry ducts in the Caerphilly hotels and care homes, alongside kitchen grease ducts.
Yes. The fan at the top of an Oakdale or city-centre riser is where grease throws off the blades and the run ends - we degrease it and its housing, because a loaded fan is what finally stops a system pulling.
We fit compliant access panels where the ductwork has none, so every internal section can be reached, cleaned, inspected and certified - common in the older Oakdale conversions where the run was boxed in with no hatches.
Local knowledge
The Sirhowy Tramroad was built through Blackwood in 1797, laid before the settlement grew so that its wagons ran straight down what is now the High Street. The coal and iron trade it served is gone, and modern premises hide their dust inside sealed ductwork instead, where grease and debris build unseen until airflow fails or fire finds a path. We clean and inspect ventilation and extract ductwork across the town, from Oakdale to Pontllanfraith, then hand over photographic before-and-after evidence of every run. What the tramroad once carried in the open now moves hidden overhead, and it needs the same clear path.
