Bisham kitchen extract cleaning
We cover Bisham for kitchen extract cleaning. Out-of-hours visits, a fixed quote and a written report with photos as standard.
- An inspection that picked up a dirty extract
- Grease drips onto cooking equipment
- A kitchen taken over without any extract records
What happens on the day
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes a single shift for most kitchens, with long duct runs and tall risers needing more time, and we clear up before we go. A quick note on how to find the site and where to park makes a visit to Bisham run smoothly.
- First the diagnosis: a survey of the whole system and its access points.
- We record grease levels at set points, then fix the price.
- We arrive after close, protect the area and contain the waste.
- Heavy deposits are scraped by hand and the system degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
Getting ready for the visit
- Let us know about parking and loading
- Mention any sign-in, permit or induction we need
- Arrange a key holder or contact on site
Get a fixed quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Kitchen extract cleaning for kitchens and businesses in Bisham
The ducts are where most of the grease hides. Access panels let us into the duct runs and risers, removing thick grease by hand, then using degreasers, hot water or steam to suit the deposit. Any section we can’t reach is recorded on the report, and new panels can be fitted. Common call-outs are for rancid smells from grease in the duct and a system with no record of a TR19 clean, across discharge points, plenums and filters and canopies and hoods. Kitchen extract cleaning, TR19 cleaning, extraction cleaning: whatever you call it, in Bisham it means the same thing to us: the whole system, cleaned and certificated.
We clean every reachable part of the system in Bisham: canopy, plenum, filters, ducts, risers and fan, and the discharge where it can be reached.
Work in a small place like Bisham starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

How we price kitchen extract cleaning
The survey tells us what the work involves. The main factors are:
- When the work can happen, such as evenings, overnight or weekends
- Parking and loading at the site
- The number of sites or systems
- Whether we need access equipment or extra panels
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before any work starts.
What we need to know
When you call or email, these details help:
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
Getting a quote does not take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
When something else is needed
In fairness, there are a few things this work won’t fix:
- A damper that sticks or has a damaged link
- A fan motor that has burnt out
- A duct that is holed or coming apart
If you are not sure, just ring 0345 646 2711 or drop us a line and we’ll give you a straight answer.

Kitchen extracts in Bisham
Food Standards Agency records include about 19 pubs and bars and about 5 hotels, B&Bs and guest houses in Bisham and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Bisham sits within the area of Buckinghamshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Environmental health officers from Windsor and Maidenhead council inspect food businesses in Bisham. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Bursars and site managers at schools such as Bisham Church of England Academy tend to book extract cleaning for when the kitchen is empty. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Marlow Community Hospital is the nearest hospital to Bisham, about 1.1 miles north.
Bisham is about 1 mile south of Marlow, in Buckinghamshire. Every kind of commercial site in Bisham, kitchen extract cleaning is something we can help with.

Signs you need kitchen extract cleaning in Bisham
Hours of cooking are the biggest factor. Under BESA guidance, heavy use of 12 to 16 hours a day means a clean at least every 3 months, moderate use every 6 months and light use every 12. Those are minimums, and grease readings can show a kitchen needs cleaning sooner.
What we are most often called out for:
- Stale cooking odours from the system
- A system with no record of a TR19 clean
- Missing paperwork after a change of operator
- Years of baked-on grease in the ducts
Where a hall near Church of All Saints, or anywhere in Bisham, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Common questions in Bisham
Which environmental health team covers Bisham?
In Bisham, it’s Windsor and Maidenhead council that carries out food hygiene inspections. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Who is the fire and rescue service for Bisham?
Bisham is in the area of Buckinghamshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained to keep the area clean.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
How often should a kitchen extract be cleaned?
Under BESA guidance, the minimum depends on how long you cook each day: 3-monthly for heavy use, 6-monthly for moderate use and 12-monthly for light use. Measured grease levels set the real interval.
Can you quote from pictures?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
Do you work in Bisham?
Yes. We cover Bisham and across Buckinghamshire, as part of our work across South East England and London. To book, give us a ring on 0345 646 2711 or use the quote form.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
Part by part
Extract fan and discharge
Some systems have attenuators to cut noise, and they hold grease. Where they can be cleaned, they are, and the report notes anything that cannot.
Schools, hospitals and care homes
Some healthcare kitchens never fully close. We plan the clean around meal times and work in a contained, tidy way with as little disruption as possible.
Between visits
Simple habits between visits make a real difference. We recommend:
- Clean grease off the canopy surfaces regularly
- Tell us when the extract starts to drip or smell
- Empty any grease troughs or cups on the canopy
- Clean the grease filters regularly between TR19 cleans
Every clean ends with a photo report. Before and after pictures show each part of the system, alongside a list of what was cleaned, anything out of reach and the recommended next clean date.
Keep the fan on throughout service. Switching it off early leaves vapour to settle on the canopy and plenum, and the next clean has more to do.
Why deal with it now?
Putting it off simply moves the grease further down the duct. Over time, soft grease bakes into a harder, thicker crust, which is slower to clean. Staying on a regular cycle keeps each clean manageable. Systems in rural buildings are often out of sight and out of mind.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.
