About our ductwork cleaning in Colnbrook
No two duct runs are the same, in Colnbrook or anywhere else. Some run a short distance to an outside wall, others climb several floors to the roof. The survey traces the route and finds every access point before we quote. Typical jobs include years of grease along the duct floor and thick deposits at the bottom of a vertical duct, on multi-storey ducts, attenuators and vertical risers.
In a village or hamlet like Colnbrook, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
The paperwork matters as much as the work. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

FAQs for Colnbrook
Which council inspects kitchens in Colnbrook?
In Colnbrook, it’s Slough council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can you work in Colnbrook outside opening hours?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Colnbrook needn’t be disturbed. Your opening times are the first thing we ask for.
What do you need from me for a quote?
A short description and a few pictures plus the address and your hours. We’ll ask for anything else we need.
Who is responsible for fire safety on the premises?
The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
What happens to the waste?
We take it away at the end of the visit. During the work, it’s contained to keep the area clean.
What about areas you cannot get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
What paperwork do you give after a duct clean?
When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. The report shows readings, pictures and any sections we couldn’t reach.
How long will the duct clean take?
Allow a shift or more, depending on the length of the runs and the number of access points. The survey tells us how long your duct needs.
Leave it or put it right?
Grease left in a duct in Colnbrook hardens over time. Heat and age turn it into a thick, stubborn crust, which makes each delayed clean a bigger one. In a small place like Colnbrook, a system that fails can take a site out of use.
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and why the quote is fixed before work begins.

Fixed quotes for ductwork cleaning in Colnbrook
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Parking and loading at the site
- How many systems or sites are involved
- The condition we find in the survey
- Site requirements such as sign-in and permits
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before we start.
Helping us quote
To speed up the quote, send us:
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before we start.
Keeping the system healthy
So the system stays in good health:
- Run the extract fan throughout service
- Don’t block access panels with shelving or stock
- Keep grease filters clean and fitted whenever you cook
- Flag drips from the duct right away
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
The less grease gets past the canopy, the cleaner the duct stays. Keep the filters clean, well fitted and in place whenever you cook.
Grease, kitchens and Colnbrook
The FSA’s food hygiene register includes about 3 bars, pubs and nightclubs and about 6 hotels and guest houses within 1.5 miles or so of the middle of Colnbrook. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. In Colnbrook, food businesses are inspected by environmental health officers from Slough council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Colnbrook falls to Royal Berkshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
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. 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.

Honest limits
To be straight with you, some problems need a different fix:
- An extract fan that has stopped working
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
- Fire dampers that do not close (they need testing and remedials)
If you’re not sure, just call 0345 646 2711, or email photos and we’ll give you a straight answer before booking.
Parts of the system we cover
- Attenuators
- Vertical risers
- Horizontal duct runs
- Access panels
- Multi-storey ducts
- Bends and junctions
Common problems we fix in Colnbrook
Risers carry the extract up through the building. Grease collects on the riser walls and gathers at the bottom as liquid grease runs down. Panels along the riser make proper cleaning possible.
Any of these means the system needs a check-up:
- Years of grease along the duct floor
- A duct clean needed for an insurer
- Duct runs with no cleaning record
- Gaps where access panels were never fitted
School kitchens, at schools like Colnbrook Church of England Primary School for example, are usually cleaned in the holidays so no lunches are lost.

Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
