Chepstow · 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 Chepstow, and certify it to the TR19 Grease standard your insurer expects.
Chepstow
Chepstow 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.
Right across Chepstow, from High Street through Moor Street to Welsh Street, 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 Chepstow schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - racecourse hospitality suites, pub carveries and takeaway ranges - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Chepstow 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 High Street and Welsh Street, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Chepstow 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 Chepstow hotels, care homes and gyms.
On the ground in Chepstow
We are in Chepstow's ductwork and plant every week. The proof is the jobs, not the stock photos.
An established apartment block in Chepstow had built-up grime forming a slime layer down the bin chute, with a foul smell reaching the communal corridors. We washed the chute from the top with a rotary jet, then disinfected and deodorised the ground-floor lobby. The odour and build-up were cleared and the chute was left clean and disinfected.
When it is due
Ductwork rarely warns you politely. In a busy Chepstow 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 Chepstow insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Moor Street 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 Chepstow 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 Welsh Street 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 Chepstow fire logbook.
Why it matters
Three duties push every Chepstow 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 Chepstow 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. A live TR19 Grease certificate is what a Chepstow 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 Monmouthshire 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 High Street kitchen sits in a tighter band than a daytime Moor Street cafe. We measure the grease load and confirm your interval.
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 Welsh Street where the runs are long and awkward.
Yes - from High Street and Moor Street kitchens to the offices, schools and industrial units across Chepstow and the wider Monmouthshire.
Yes. We clean the dry ductwork and air-handling in Chepstow offices, schools and public buildings, and the lint-heavy laundry ducts in the Monmouthshire hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the High Street and Moor Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
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 Welsh Street conversions where the run was boxed in with no hatches.
Little, if it is planned. We survey the Chepstow run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Moor Street cookline is back in service for the next shift.
Local knowledge
Isambard Kingdom Brunel's tubular railway bridge opened across the Wye at Chepstow in 1852, a wrought-iron design that carried trains where the river gorge made an ordinary span impossible. Hidden structure doing unseen work describes a building's ductwork just as well. Grease, dust and debris build up out of sight inside extract runs until airflow falls and fire risk climbs. We clean ducting back to bare metal and record it, so what you cannot see is proven clean rather than assumed.
