Stonehaven · 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 Stonehaven, and certify it to the TR19 Grease standard your insurer expects.
Stonehaven
Stonehaven rates dozens 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 Allardice Street to Barclay Street and Arbuthnott Street, 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.
The same crews clean dry ventilation and air-handling ductwork in offices, schools and civic buildings, plus the combustible lint runs behind hotel and care-home dryers. High-turnover sites - harbour chip shops, hotel kitchens, and care-home and school canteens - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Stonehaven 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 Allardice Street and Arbuthnott Street, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Stonehaven 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 Stonehaven hotels, care homes and gyms.
On the ground in Stonehaven
We are in Stonehaven's ductwork and plant every week. The proof is the jobs, not the stock photos.
A town-centre primary school in Stonehaven had a heavy blanket of dust and debris settled through the classroom supply ducting serving the main rooms. We cleaned the fresh-air ducting with air whips under negative pressure and renewed the AHU panel filters. Air through the main floor felt noticeably fresher and the dust complaints stopped.
When it is due
Ductwork rarely warns you politely. In a busy Stonehaven kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto an Allardice Street cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Stonehaven insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Barclay Street 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 Stonehaven 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 Arbuthnott Street conversions - and protect the kitchen.
Canopy to roof fan, down to bare metal, with before-and-after grease-depth evidence.

Why it matters
Three duties push every Stonehaven 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 Stonehaven 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 an Allardice 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 Stonehaven 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 Aberdeenshire Council weighs the physical state of the premises, ventilation counted within it. A grease-blocked extract can pull down the result 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 Allardice Street kitchen sits in a tighter band than a daytime Barclay Street 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 an Allardice Street operator's insurer and fire risk assessor expect.
Yes. We work overnight, early mornings and closing days for the Allardice Street and Barclay Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
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 Allardice Street and Arbuthnott Street where the runs are long and awkward.
Yes. We clean the dry ductwork and air-handling in Stonehaven offices, schools and public buildings, and the lint-heavy laundry ducts in the Aberdeenshire hotels and care homes, alongside kitchen grease ducts.
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 Arbuthnott Street conversions where the run was boxed in with no hatches.
Yes. The fan at the top of an Arbuthnott Street 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.
Local knowledge
Every Hogmanay, Stonehaven's High Street fills for the Fireballs ceremony, when swingers march the length of the town whirling blazing wire cages overhead to burn off the old year. Fire and hot metal demand respect, and so does the greasy dust that collects inside kitchen and workshop ductwork. We strip and clean ducting back to bare metal, photograph access hatches before and after, and log the work so the fire risk in the run is measured rather than guessed.
