Boston · 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 Boston, and certify it to the TR19 Grease standard your insurer expects.
Boston
Boston 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.
From Market Place to Strait Bargate and Petticoat Lane, 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.
It is not only kitchens: we also clean the dry supply and extract ductwork in Boston offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - Boston College, the Pilgrim Hospital, the Market Place and the town hotels - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Boston insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Because the standard is written around film thickness, it sets the depth that triggers a clean and re-test. In the mixed roof spaces around Market Place and Petticoat Lane, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Boston run through existing hatches and new ones we cut, clean back to bright metal, take before-and-after grease-depth figures at set points, and certify it to TR19 Grease with those depths on the 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 Boston hotels, care homes and gyms.
On the ground in Boston
We are in Boston's ductwork and plant every week. The proof is the jobs, not the stock photos.
A South End food-processing unit in Boston, one of the vegetable-packing and cooked-meat plants that ring the Haven, vented a steam oven through ductwork furred with protein soil and condensate rather than fryer grease. We swabbed the run, jetted the water-soluble crust off the internal walls with a rotating lance, and flushed the collection trap at the base where cooking liquor had pooled and turned rancid. The extract fan was drawn, stripped and rebalanced, airflow re-read against the commissioning figure, and a fall and drain point added so condensate sheds outward instead of standing in the horizontal and dripping back onto the packing line.
When it is due
Ductwork rarely warns you politely. In a busy Boston kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Market Place cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Boston insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Strait Bargate 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 Boston 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 Petticoat Lane conversions - and protect the kitchen.

Why it matters
Three duties push every Boston 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 Boston 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 Market Place 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. To a Boston insurer a current TR19 Grease certificate is the proof the extract has been kept up. Let it lapse and a fire claim can be scaled back or declined outright - the kind of gap nobody wants to find with the kitchen already gutted.
Hygiene and environmental health. Boston Borough Council food hygiene inspections assess the physical condition of premises, ventilation included. A grease-clogged system can count against the rating an Environmental Health Officer awards, quite apart from the smell and the falling extract performance your staff have to work in.
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 Market Place kitchen sits in a tighter band than a daytime Strait Bargate cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Boston run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Strait Bargate cookline is back in service for the next shift.
Yes - from Market Place and Strait Bargate kitchens to the offices, schools and industrial units across Boston and the wider Lincolnshire.
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 Petticoat Lane conversions where the run was boxed in with no hatches.
Yes. The fan at the top of a Petticoat Lane 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.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Market Place operator's insurer and fire risk assessor expect.
Yes. We clean the dry ductwork and air-handling in Boston offices, schools and public buildings, and the lint-heavy laundry ducts in the Lincolnshire hotels and care homes, alongside kitchen grease ducts.
