How we handle ductwork cleaning in Blacknest
Ductwork in Blacknest is cleaned the same thorough way as everywhere else we work: readings at set points, heavy grease scraped out by hand, then degreasing to suit the deposit. Readings are taken again afterwards and pictures go into your report. The work covers horizontal duct runs, attenuators and multi-storey ducts, and common reasons people get in touch are sections of duct with no access panels and years of grease along the duct floor.
Somewhere as small as Blacknest, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What ductwork cleaning can’t fix
In fairness, some problems need a different fix:
- Faulty fire dampers
- An extract fan that has stopped working
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we will tell you honestly before booking.
What the work covers
- Bends and junctions
- Attenuators
- Vertical risers
- Multi-storey ducts
- Access panels
- Horizontal duct runs
Different parts, different methods
Bends and transitions
Wherever the duct turns or changes size, grease builds up. Slowing air leaves grease behind, so these points get extra attention.
Access panels
Panels have to seal properly once they’re closed, so grease and air stay inside the duct. We’ll tell you if any panel needs replacing.
What affects the cost of ductwork cleaning
A fixed price needs a few facts first. We look at:
- How easy every part is to reach
- Site requirements such as sign-in and permits
- Whether several sites go on one quote
- The size of the system
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.
What we need to know
What to send for a quote:
- A few general shots of the system
- Your last certificate, test record or report
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
For a fixed quote, call 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
How the visit works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes from a few hours to more than one visit, depending on duct length and access. Pictures of the system and its access let us plan the work in Blacknest before we set off.
- Diagnosis: a survey of the duct’s route, size and access.
- You get a fixed price before work starts.
- Each section is cleaned in turn through its access panel.
- Bends, risers and the base of each riser get extra attention.
- Readings, photos and a recommended next clean date complete the job.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Plan for cooking equipment or plant to be off before we arrive
- Mention any locked doors, roof access or ceiling voids
How to get a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, ring 0345 646 2711 or use the quote form.
Advice
What we’re called out for in Blacknest
The further the air travels from the cooking, the cooler it gets. As it cools, the grease it carries condenses onto the duct walls, which is why ducts go on gathering grease well beyond the filters.
Any of these means the system needs a check-up:
- A grease test showing the duct is overdue
- Grease seeping out of the duct seams
- Sections of duct with no access panels
- Years of grease along the duct floor
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Blacknest is Heatherwood Hospital, about 2.7 miles west.
What your quote should include
- Proof of insurance
- When they can work, and whether that’s outside your opening hours
- Whether VAT is included
- What happens if part of the system can’t be accessed
Kitchen extracts in Blacknest
The FSA’s food hygiene register shows about 22 cafés, restaurants and staff canteens within roughly a mile and a half of the centre of Blacknest. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. In Blacknest, food businesses are inspected by environmental health officers from Windsor and Maidenhead council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for Blacknest is Royal Berkshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Historic houses near Blacknest, such as St Leonard's Hill about 4.2 miles north, are a reminder that older buildings with event kitchens can have long, awkward duct routes. For schools such as Holy Trinity CofE Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Your questions about ductwork cleaning in Blacknest
Will you come out to Blacknest?
Yes. Blacknest is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Do you work overnight in Blacknest?
Yes, nights and weekends are routine for us. That way a site in Blacknest doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
How do you know if the ductwork needs cleaning?
Signs include grease dripping from joints, smells and a fan working harder, but the only sure way is to measure. Grease thickness testing shows exactly where the duct stands.
What if part of the duct cannot be reached?
Ductwork needs access to be cleaned. Those parts are listed, and we can install panels so they’re reached next time.
What does ductwork cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we will typically reply within one working day.
How long does it take to clean extract ducts?
Duct length, access and grease levels all affect it. Typically it takes anything from a few hours to several visits, depending on the length of duct.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Ring any time and tell us what’s happened.
Do I get a certificate for ductwork cleaning?
When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. It includes readings, pictures and any unreachable sections.

What else we do in Blacknest
Managing agents and facilities teams in Blacknest
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Why deal with it now?
Fire inside a duct is out of sight and out of reach. It can travel through the ductwork to other parts of the building, which is why the duct matters as much as the canopy. With notice, the visit to Blacknest can be fitted around your bookings and events.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.
