Sandhurst · 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 Sandhurst, and certify it to the TR19 Grease standard your insurer expects.
Sandhurst
Sandhurst 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.
Kitchens across Sandhurst work out of tight, mixed premises - Yorktown Road, College Town, Rackstraw Road - their extract snaking through concealed voids to roof-mounted fans. We take the whole run to the TR19 Grease standard, hood to fan, reaching the horizontal legs and vertical risers a canopy wipe never touches.
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 - military academy messes, pub and hotel kitchens, care-home kitchens and the busy town-centre takeaways - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Sandhurst 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 Yorktown Road and Rackstraw Road, 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 Sandhurst 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 Sandhurst hotels, care homes and gyms.
On the ground in Sandhurst
We are in Sandhurst's ductwork and plant every week. The proof is the jobs, not the stock photos.
At a well-known dental practice in Sandhurst, a heavy blanket of atmospheric dust had settled through the fresh-air ducting feeding the occupied rooms. We worked the dry ventilation ducting with brushes and HEPA extraction, then cleaned and refitted the ceiling diffusers. Air quality lifted across the offices and the client was really pleased with how it was turned round. We fitted the visit into the mid-afternoon lull so staff weren't disturbed.
When it is due
Ductwork rarely warns you politely. In a busy Sandhurst kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Yorktown Road line, a rim of grease at the filters, or a Sandhurst insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying College Town 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 Sandhurst 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 Rackstraw Road 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 Sandhurst fire logbook.
Why it matters
Three duties push every Sandhurst 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 Sandhurst 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 Yorktown Road 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 Sandhurst 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. When Bracknell Forest Council carries out a food hygiene inspection it judges the physical state of the premises, and ventilation is part of that. A grease-choked extract can pull down the rating an Environmental Health Officer gives, on top of the odour and the weakening airflow your staff put up with.
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 Yorktown Road kitchen sits in a tighter band than a daytime College Town 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 Yorktown Road and Rackstraw Road where the runs are long and awkward.
Yes. We work overnight, early mornings and closing days for the Yorktown Road and College Town kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes. We clean the dry ductwork and air-handling in Sandhurst offices, schools and public buildings, and the lint-heavy laundry ducts in the Berkshire hotels and care homes, alongside kitchen grease ducts.
Yes - from Yorktown Road and College Town kitchens to the offices, schools and industrial units across Sandhurst and the wider Berkshire.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Yorktown Road operator's insurer and fire risk assessor expect.
Little, if it is planned. We survey the Sandhurst run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a College Town cookline is back in service for the next shift.
Local knowledge
Sandhurst grew from four farming villages whose old holdings - Rackstraws Farm, Snaprails, Caves Farm and College Farm - survive now only as street and estate names, before the railway arrived in 1849 and the country houses and light industry followed. The workshops and kitchens that replaced the fields hide their dust and grease inside sealed ductwork, 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.
