Windsor · 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 Windsor, and certify it to the TR19 Grease standard your insurer expects.
Windsor
Windsor 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 Peascod Street to High Street and Clewer, 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.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Windsor schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - hotel and riverside restaurant kitchens, pub and gastropub kitchens, visitor-attraction catering 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 Windsor 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 Peascod Street and Clewer, 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 Windsor 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 Windsor hotels, care homes and gyms.
On the ground in Windsor
We are in Windsor's ductwork and plant every week. The proof is the jobs, not the stock photos.
A family-run library in Windsor had dust and debris gathered in the branch ducts feeding its reading room, leaving the air barely moving. We isolated the zones, brushed out the internal ducting and washed down the fan coil unit. Airflow came back up to spec and the system was left visibly clean, and the client booked us back in there and then. The receptionist kept us going with a steady supply of brews through the morning.
When it is due
Ductwork rarely warns you politely. In a busy Windsor kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Peascod Street cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Windsor insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying High 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 Windsor 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 Clewer 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 Windsor fire logbook.
Why it matters
Three duties push every Windsor 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 Windsor 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 Peascod 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 Windsor 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. Food hygiene inspections by Royal Borough of Windsor and Maidenhead take in the condition of the building, ventilation included, so a grease-laden system can cost you on the rating an Environmental Health Officer awards - never mind the smell and the dropping extraction your kitchen team works under.
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 Peascod Street kitchen sits in a tighter band than a daytime High 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 a Peascod Street operator's insurer and fire risk assessor expect.
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 Clewer conversions where the run was boxed in with no hatches.
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 Peascod Street and Clewer where the runs are long and awkward.
Yes - from Peascod Street and High Street kitchens to the offices, schools and industrial units across Windsor and the wider Berkshire.
Yes. We work overnight, early mornings and closing days for the Peascod Street and High Street 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 Windsor offices, schools and public buildings, and the lint-heavy laundry ducts in the Berkshire hotels and care homes, alongside kitchen grease ducts.
Local knowledge
Windsor was known for centuries for the quality of its beer, until the last of its breweries closed in 1931 and the trade fell silent for eighty years before returning to the Vansittart Estate in 2010. Modern premises hide their process air inside sealed ductwork, where grease and debris build 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.
