About our ductwork cleaning in Cold Harbour
In doctor’s terms, the ductwork is the system’s arteries: diagnose where grease has built up, clear it and confirm the result. Readings taken before and after show the difference, alongside before and after photos. If you have a duct clean needed for an insurer and a rancid smell from the extract duct, we can help.
For a kitchen in or near Cold Harbour, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Why it’s worth doing now in Cold Harbour
A partly blocked duct slows the airflow. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy, and grease may start to leak from joints. Systems in rural buildings are often out of sight and out of mind.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.

Your questions about ductwork cleaning in Cold Harbour
Can a school canteen extract in Cold Harbour be done out of term time?
Yes. The holidays are the usual time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Cold Harbour, it pays to plan holiday dates ahead. You can call us on 0345 646 2711 or use the quote form with the dates the site is empty.
Is Cold Harbour within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
What happens to the waste?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.
How do you know if the ductwork needs cleaning?
A grease thickness test gives the answer. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
What about areas you cannot get to?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
What’s involved in cleaning extract ducts?
After a survey and grease readings, the duct is opened up through its access panels. We clean the runs and risers section by section, and test again when we’re done.
Can you clean ductwork with no access panels?
Without a way in, a section cannot be cleaned properly. We record those sections on the report and can fit access panels.
Can extra access doors be added to the duct?
Yes. The survey or clean shows where sections couldn’t be reached, and we can fit them so those sections are cleaned in future.

How we price ductwork cleaning
The diagnosis comes before the price. The main factors are:
- How big the system is
- A single visit or a regular plan
- Any permits to work or inductions
- Access, including roofs, risers and ceiling voids
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
What to send for a quote
What to send for a quote:
- Your opening hours and when the area is out of use
- Any previous report or certificate
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
What we’re called out for in Cold Harbour
The further the air travels from the cooking, the cooler it gets. As it cools, the grease it carries condenses onto the duct walls, so duct runs keep collecting grease long after the canopy.
Look out for any of the following:
- Years of grease along the duct floor
- Heavy grease at the base of a riser
- Fat dripping from the ductwork
- A duct clean needed for an insurer
If you run catering at a historic house or estate in the area (Harleyford Manor is about 3.3 miles north), event kitchens in older buildings often have awkward duct runs that need planning.
What to look for in a quote

What happens on the day
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us.

- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.

Advice
Kitchen extracts in Cold Harbour
There are about 5 restaurants, cafés and canteens across Cold Harbour and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. The duct above a busy canopy coats itself in grease long before anyone sees it. Food hygiene inspections in Cold Harbour are the job of Windsor and Maidenhead council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Cold Harbour is covered by 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.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Cold Harbour is St Mark's Hospital, about 2.8 miles north-east. Volunteers running a hall kitchen near Saint Peter, or anywhere in Cold Harbour, may not know when the extract was last cleaned, and a grease test settles it.

Near you in Cold Harbour

Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Facilities teams in offices, schools and healthcare sites book us too across Windsor and Maidenhead. Work can be phased by floor, building or site around the people who use them.
Staff cleaning versus specialist work
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 will take a look and give you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
What ductwork cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Parts of the duct with no way in
- A worn-out fan that needs replacing
- Undersized or badly laid-out ducts
If you are not sure, just call 0345 646 2711, or email photos and we’ll give you a straight answer before you book.
