Maidenhead · 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 Maidenhead, and certify it to the TR19 Grease standard your insurer expects.
Maidenhead
Maidenhead rates around 1,470 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.
The city's kitchens sit in tight, mixed stock - King Street, Queen Street, Nicholsons - with long concealed duct runs up to roof fans. We clean the full run to the TR19 Grease standard, canopy to fan, including the horizontal and vertical sections a canopy-only clean leaves coated.
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 - the local college, St Mark's Hospital, York Road and the town hotels - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Maidenhead 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 King Street and Nicholsons, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Maidenhead 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 Maidenhead hotels, care homes and gyms.
On the ground in Maidenhead
We are in Maidenhead's ductwork and plant every week. The proof is the jobs, not the stock photos.
A public library in Maidenhead had fine atmospheric particulate and grey dust settling inside the supply ducts feeding the archive room. We ran manual push-rod brushes and high-filtration HEPA vacuums gently through the linings without generating vibration, leaving the supply air clean and protecting the rare books. The archive is held to strict humidity and temperature, so we worked under its monitors throughout.
When it is due
Ductwork rarely warns you politely. In a busy Maidenhead 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 King Street line, grease crusting at the filter rims, or a Maidenhead 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 Queen Street 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 Maidenhead 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 Nicholsons 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 Maidenhead 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 Maidenhead 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 King 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 Maidenhead 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. Royal Borough of Windsor and Maidenhead food hygiene inspections assess the physical condition of premises, ventilation included. A grease-clogged system can count against the rating 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 King Street kitchen sits in a tighter band than a daytime Queen Street cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Maidenhead run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Queen Street cookline is back in service for the next shift.
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 Nicholsons conversions where the run was boxed in with no hatches.
Yes. We work overnight, early mornings and closing days for the King Street and Queen 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 Maidenhead offices, schools and public buildings, and the lint-heavy laundry ducts in the Berkshire 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 King Street and Nicholsons where the runs are long and awkward.
Yes - from King Street and Queen Street kitchens to the offices, schools and industrial units across Maidenhead and the wider Berkshire.
