Dumbarton · 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 Dumbarton, and certify it to the TR19 Grease standard your insurer expects.
Dumbarton
Dumbarton 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 Dumbarton, from College Street through Quarry Knowe to Dalreoch, 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.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Dumbarton schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - hospital kitchens, college refectories, hotel and pub kitchens and the busy town-centre takeaways - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Dumbarton insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard is written in film thickness: once grease reaches a set depth the run has to be cleaned and proven again. In the crowded roof voids off College Street and Dalreoch, a wipe of the canopy and filters never reaches the ductwork behind them, where the grease that carries fire quietly gathers. We work the whole Dumbarton run through hatches already in place and others we cut, bring it back to bright metal, note grease depths at fixed stations before and after, and certify to TR19 Grease with the closing figures logged.
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 Dumbarton hotels, care homes and gyms.
On the ground in Dumbarton
We are in Dumbarton's ductwork and plant every week. The proof is the jobs, not the stock photos.
Fine building dust had settled across the dry ventilation ducting and ceiling diffusers at a much-loved Dumbarton veterinary practice. We power-brushed the fresh-air ducting under HEPA negative pressure and cleared out the air handling unit. Airflow came back up to spec and the whole system was left visibly clean, which the team were glad to have sorted. We left a set of comparison images and a clean certificate for their health and safety folder.
When it is due
Ductwork rarely warns you politely. In a busy Dumbarton kitchen these are the tells.
Watch for steam that hangs in the room, cooking smells creeping back over the tables, a canopy weeping onto a College Street line, grease crusting at the filter rims, or a Dumbarton insurer or fire assessor calling for a TR19 certificate you do not hold. How often it needs doing rides on the cooking load - a hard-frying Quarry Knowe kitchen far more than a quiet daytime cafe - and the certificate fixes that interval, so the next clean is planned, not chanced.
How it runs
Inspect the full Dumbarton 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 Dalreoch 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 Dumbarton fire logbook.
Why it matters
Three duties push every Dumbarton operator to keep ductwork clean, and they reinforce one another.
Fire safety law. Under the Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006, the duty-holder for a Dumbarton 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 College 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 Dumbarton 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. West Dunbartonshire Council food hygiene inspections assess the physical condition of premises, ventilation included. A grease-clogged system can count against the result 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 College Street kitchen sits in a tighter band than a daytime Quarry Knowe cafe. We measure the grease load and confirm your interval.
Yes. We work overnight, early mornings and closing days for the College Street and Quarry Knowe kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes - from College Street and Quarry Knowe kitchens to the offices, schools and industrial units across Dumbarton and the wider West Dunbartonshire.
Yes. We clean the dry ductwork and air-handling in Dumbarton offices, schools and public buildings, and the lint-heavy laundry ducts in the West Dunbartonshire 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 College Street and Dalreoch where the runs are long and awkward.
Yes. The fan at the top of a Dalreoch 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 Dalreoch conversions where the run was boxed in with no hatches.
Local knowledge
In 1938 Hiram Walker raised a vast grain distillery at the meeting of the Clyde and Leven to fill the Ballantine's blend, and at its height it was the largest grain distillery in Europe, its bonded warehouses at Dumbuck famously guarded by a gaggle of a hundred white geese known as the Scotch Watch. The distillery towers came down in the 2000s to make way for the Lomondgate development. 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 the town, then hand over photographic before-and-after evidence of every run.
