Ductwork cleaning in Sunbury-on-Thames, done properly
The ductwork is where an extract clean is won or lost. Without enough access panels, long stretches can go years without being touched. Each section we can reach is cleaned, and any we can’t is written down, so you know exactly where you stand. If you are dealing with a grease test showing the duct is overdue and thick deposits at the bottom of a vertical duct, we can put it right, from bends and junctions, horizontal duct runs and multi-storey ducts onwards.
For a pub, café or restaurant in a town like Sunbury-on-Thames, losing a day’s trade to cleaning is not an option, so cleans are booked after closing, early in the morning or on a quiet day. The kitchen is handed back clean and ready to cook.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Tell us if grease leaks from the ductwork
- Get panels fitted where the duct couldn’t be cleaned
- Diarise the next duct clean
- Run the extract fan throughout service
The report names every part of the duct that couldn’t be reached, with the reason. We can fit access panels so those sections are cleaned next time.
Book the next duct clean before the date passes. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
Part by part
Attenuators and discharge
At the end of the duct is the discharge. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.
Vertical risers
In taller buildings, a riser may pass through several floors and fire compartments, so fire dampers may be fitted where it crosses them. Damper testing is a separate service.
Managing agents and facilities teams in Sunbury-on-Thames
Facilities teams in offices, schools and healthcare sites book us too in Sunbury-on-Thames and across Surrey. Larger estates can be phased building by building around the people who use them.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

Leave it or put it right?
A partly blocked duct slows the airflow. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy and grease can drip from duct joints. Whatever the system, dirt and wear only get worse.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

Sunbury-on-Thames is covered by Surrey Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.

How it works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from a few hours to several visits, depending on the length of duct. A few photos of the system and its access points help us plan a visit in Sunbury-on-Thames.
- We start by working out how the duct runs and where it can be opened.
- Set points along the runs are tested for grease.
- We open the panels and scrape out the heaviest grease.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- We test again, take photos and note any part that couldn’t be reached.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
- Tell us the best time to work, such as after service or at a weekend

Duct length, access and grease levels all affect it. As a guide, it takes anything from a few hours to several visits, depending on the length of duct.

Common problems we fix in Sunbury-on-Thames

The symptoms we are asked about most include:
- A rancid smell from the extract duct
- Duct runs with no cleaning record
- Fat dripping from the ductwork
- Sections of duct with no access panels
Term dates shape school work: for a school like St Ignatius RC Primary School, an extract clean fits neatly into a half-term or summer break.
