Stanley · 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 Stanley, and certify it to the TR19 Grease standard your insurer expects.
Stanley
Stanley 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.
Right across Stanley, from Clifford Road through Thorneyholme Terrace to Shield Row, cooklines share tight roof space and vent through concealed ducting few operators ever see inside. We clean that entire path to the TR19 Grease standard, canopy through to fan, taking in the level pulls and the risers where grease settles thickest and a fire would run.
It is not only kitchens: we also clean the dry supply and extract ductwork in Stanley offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - care-home kitchens, school and college canteens, pub and hotel kitchens and the busy town-centre takeaways - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Stanley 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 Clifford Road and Shield Row, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Stanley 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 Stanley hotels, care homes and gyms.
On the ground in Stanley
We are in Stanley's ductwork and plant every week. The proof is the jobs, not the stock photos.
The changing-room extract grilles at a privately owned Stanley health centre were clogged with fine dust and barely pulling any air. I cleared the grilles, brushed out the flexible branches and cleaned the blades on the inline extract fan. The stale air lifted from the changing rooms and extraction was back to a proper rate, and the difference was obvious straight away. The duty manager took a short photo report for their maintenance log.
When it is due
Ductwork rarely warns you politely. In a busy Stanley kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Clifford Road cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Stanley insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Thorneyholme Terrace kitchen needs it far more often than a daytime cafe - and your certificate states the interval, so the next clean is never a guess.
How it runs
Inspect the full Stanley 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 Shield Row 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 Stanley fire logbook.
Why it matters
Three duties push every Stanley 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 Stanley 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 Clifford Road 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 live TR19 Grease certificate is what a Stanley insurer treats as evidence the system is maintained. Miss it and a fire claim may be reduced or refused - an expensive surprise once the damage is done.
Hygiene and environmental health. A food hygiene visit from Durham County Council weighs the physical state of the premises, ventilation counted within it. A grease-blocked extract can pull down the rating an Environmental Health Officer sets, quite apart from the stale smell and the tired airflow your staff work beneath all shift.
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 Clifford Road kitchen sits in a tighter band than a daytime Thorneyholme Terrace 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 Clifford Road operator's insurer and fire risk assessor expect.
Yes. The fan at the top of a Shield Row 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 Shield Row conversions where the run was boxed in with no hatches.
Yes. We clean the dry ductwork and air-handling in Stanley offices, schools and public buildings, and the lint-heavy laundry ducts in the County Durham hotels and care homes, alongside kitchen grease ducts.
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 Clifford Road and Shield Row where the runs are long and awkward.
Yes - from Clifford Road and Thorneyholme Terrace kitchens to the offices, schools and industrial units across Stanley and the wider County Durham.
Local knowledge
Tanfield Lea was once home to the Ever Ready company's largest British battery factory, one of the biggest employers the town ever had, its floors humming with production long after the pits began to close. Modern premises hide their dust and grease inside sealed ductwork instead, where debris builds unseen until airflow fails or fire finds a path. We clean and inspect ventilation and extract ductwork across Stanley, Tanfield Lea and Annfield Plain, then hand over photographic before-and-after evidence of every run. What cannot be seen is exactly what an inspection and a fire risk assessment want proven.
