Kitchen duct cleaning in Colnbrook
The part of the system nobody sees is often the dirtiest. We reach horizontal runs and vertical risers through access panels, removing thick grease by hand, then using degreasers, hot water or steam to suit the deposit. Anything out of reach is noted in the report and extra access panels can be added. If you have a new tenancy or takeover with no cleaning history and rancid smells from grease in the duct, we can help, from horizontal duct runs, vertical risers and extract fans onwards. Extraction cleaning, hood cleaning and TR19 duct cleaning all end up in the same place: a clean that goes past the canopy into the duct and fan, backed by a certificate.
The fire risk in a kitchen extract sits in the parts nobody sees: the plenum, the duct and the fan, so that’s where most of the work in Colnbrook goes.
In a small place like Colnbrook, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

What kitchen extract cleaning cannot fix
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Fire dampers that will not close (that needs damper testing and remedials)
- Fat blocking the kitchen drains
- A canopy that is too small or a system that was badly designed
Not sure which it is? You can call 0345 646 2711, or email photos and we will tell you honestly before booking.
What we work on in Colnbrook
- Vertical risers
- Discharge points
- Plenums and filters
- Horizontal duct runs
- Canopies and hoods
- Extract fans
Do you need kitchen extract cleaning in Colnbrook?
In Colnbrook, as anywhere, grease gathers where the air slows down: long horizontal runs, bends, the base of risers and around the fan. Cooler sections of duct collect the most.
Any of these means the system needs a check-up:
- An extract that no longer clears the smoke
- Stale cooking odours from the system
- An overdue clean flagged by an EHO or fire officer
- Fat running down the canopy edge
If you run catering at a healthcare site, such as a hospital like Upton Hospital about 3.2 miles north-west, the extract may need cleaning more often than a part-time kitchen.
What your quote should include
- What happens if part of the system cannot be accessed
- Whether they’re fully insured
- What paperwork you get at the end
- Whether the quote is based on a survey or pictures
In-house cleaning or a specialist?
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Colnbrook: your questions answered
Which fire service covers Colnbrook?
Fire safety enforcement in Colnbrook is handled by Royal Berkshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Is Colnbrook within the area you cover?
Yes, Colnbrook is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
How much does kitchen extract cleaning cost in Colnbrook?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
Why do insurers care about extract cleaning?
Extract grease is fuel for a kitchen fire, which is why many insurers require TR19 cleaning. Each clean gives you a certificate and photo report to show them.
What information do you need?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
What does a TR19 kitchen extract clean include?
Everything from canopy to discharge: the canopy, the plenum behind the filters, the filters, horizontal ducts, vertical risers, the fan and the discharge, plus attenuators where fitted. Any part without access is noted.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.

What we do, step by step
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes one visit for most kitchens, while large or complex systems may need more than one. For a village or hamlet like Colnbrook, tell us about narrow lanes, gates and parking when you book.
- First the diagnosis: a survey of the whole system and its access points.
- We record grease levels at set points, then fix the price.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- The sign-off: post-clean readings, a TR19 certificate and a photo report with the next clean date.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To start, call 0345 646 2711 or use the quote form.

Kitchen extracts in Colnbrook
The FSA’s food hygiene register shows about 25 restaurants, cafés and works canteens and about 13 takeaways and sandwich shops in Colnbrook and the streets around it, up to about 1.5 miles out. Wherever food is cooked under a canopy, the extract above it gathers grease and needs cleaning on a schedule. Food hygiene inspections in Colnbrook are the job of Slough council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Royal Berkshire Fire and Rescue Service covers Colnbrook. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you look after a school kitchen, at a school such as Colnbrook Church of England Primary School or anywhere near Colnbrook, the holidays are the usual time for a TR19® clean. If you run a church or community hall kitchen, near Church of St Thomas or elsewhere in Colnbrook, its extract still collects grease from every lunch and event.

Fixed quotes for kitchen extract cleaning in Colnbrook
A fixed price needs a few facts first. We check:
- Parking and loading at the site
- Site rules, permits and inductions
- The size of the system
- How many systems or sites are involved
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- Close-ups of filters, grilles, hatches or access panels
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
What the work involves, part by part
Ductwork and risers
Bends and changes of direction trap more grease than straight runs. We test at points like these before and after cleaning, so the report shows the difference.
Extract fan and discharge
Attenuators, where fitted, can soak up grease and need attention. Where they can be cleaned, they are, and the report notes anything that cannot.
