Stockton-on-Tees · 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 Stockton-on-Tees, and certify it to the TR19 Grease standard your insurer expects.
Stockton-on-Tees
Stockton-on-Tees rates around 1,500 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.
From High Street to Yarm Lane and Riverside, the town's cooklines vent through long hidden ducting that climbs to a roof fan. We clean it end to end to the TR19 Grease standard - not just the canopy, but the flat and rising sections where grease really collects.
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 - the local university centre, the University Hospital of North Tees, the Stockton Globe and the borough hotels - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Stockton-on-Tees insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Grease is measured by thickness, and the standard sets the depth at which a system must be cleaned and re-tested. Around High Street and Riverside, where the concealed runs thread through mixed roof voids, a canopy-and-filter wipe leaves the ductwork itself - the long hidden sections where grease accumulates and a fire travels - untouched. We access the full Stockton-on-Tees run through existing and newly fitted inspection hatches, clean to bare metal, record before-and-after grease-depth readings at set points, and issue a TR19 Grease certificate with a post-clean depth record.
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 Stockton-on-Tees hotels, care homes and gyms.
On the ground in Stockton-on-Tees
We are in Stockton-on-Tees's ductwork and plant every week. The proof is the jobs, not the stock photos.
A launderette in Stockton-on-Tees had compacted fabric fibre and heavy lint filling more than half the cross-section of the low-level duct. We ran localised vacuum extraction and swept the long horizontal runs with non-sparking flexible rods, doubling the velocity at the dryer outlets so the elements ran safely. The launderette was at half-capacity, so we cordoned the work zone off with safety tape.
When it is due
Ductwork rarely warns you politely. In a busy Stockton-on-Tees kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a High Street line, a rim of grease at the filters, or a Stockton-on-Tees insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Yarm Lane 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 Stockton-on-Tees 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 Riverside 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 Stockton-on-Tees fire logbook.
Why it matters
Three duties push every Stockton-on-Tees 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 Stockton-on-Tees 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 High 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. Your Stockton-on-Tees insurer expects a current TR19 Grease certificate as proof the duct is clean. Without one, a fire claim can be cut back or turned down altogether - a costly thing to find only after a fire.
Hygiene and environmental health. A food hygiene visit from Stockton-on-Tees Borough 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 High Street kitchen sits in a tighter band than a daytime Yarm Lane cafe. We measure the grease load and confirm your interval.
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 Riverside conversions where the run was boxed in with no hatches.
Yes. We clean the dry ductwork and air-handling in Stockton-on-Tees offices, schools and public buildings, and the lint-heavy laundry ducts in the County Durham hotels and care homes, alongside kitchen grease ducts.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a High Street operator's insurer and fire risk assessor expect.
Yes - from High Street and Yarm Lane kitchens to the offices, schools and industrial units across Stockton-on-Tees and the wider County Durham.
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 High Street and Riverside where the runs are long and awkward.
Yes. The fan at the top of a Riverside 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.
