Ductwork cleaning in Gravesend, done properly
Nobody sees duct grease building, so nobody notices it until something goes wrong. A flare-up drawn up from the range can light it, and fire can then run along the ductwork to other parts of the building. Cleaning the duct takes that fuel away. We’re often asked to deal with stale grease odours from the duct and thick crusts of old grease along the duct, across bends and junctions, access panels and vertical risers.
Many kitchens in a town like Gravesend were fitted into buildings built for something else, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Where the duct cannot be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.
The paperwork matters as much as the work. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

How we price ductwork cleaning
You will get a fixed price before any work starts. It takes into account:
- Whether we need access equipment or extra panels
- One-off work versus a regular cycle
- Whether several sites go on one quote
- The times the site is available
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
Helping us quote
When you call or email, it’s useful to have:
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Detail shots of panels, filters and grilles
- Wide pictures of the system and the area around it
Getting a quote does not take long. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Why deal with it now?
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. Catching it early in Gravesend means you choose the day.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Why Gravesend businesses choose us
- Full insurance on every job
- One number for every site across the South East and London
- A fixed price before any work starts
- CHAS and SafeContractor accredited, with ISO 9001

What happens on the day
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a shift or more, depending on the length of the runs and the number of access points, and the area is cleaned down before we leave. For a site in a town like Gravesend, tell us your opening hours, where we can park and how we reach the roof or plant.
- We map the duct route and check where the access panels are.
- Set points along the runs are tested for grease.
- We open the panels and scrape out the heaviest grease.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Tell us about site rules, permits or sign-in
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
To get a fixed quote, phone us on 0345 646 2711 or email us 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 usually come back within one working day.
Advice
Grease, kitchens and Gravesend
The coast is only about 2 miles from Gravesend. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. The FSA’s food hygiene register includes about 55 bars, pubs and nightclubs and about 3 hotels, B&Bs and guest houses in and around Gravesend, up to about a mile and a half out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Fire safety in Gravesend falls to Kent 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.
For schools such as Whitehill Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. If you cook for passing trade around Gravesend station, the extract can be cleaned between your last and first customer.

When to call us in Gravesend
Grease settles fastest where the air slows down. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
If you notice any of these, it’s worth a diagnosis:
- Duct runs with no cleaning record
- Grease pooling at the foot of the riser
- Fat dripping from the ductwork
- A duct clean needed for an insurer
If you run catering at a healthcare site, such as a hospital like Gravesham Community Hospital about 1 mile north-west, the extract may need cleaning more often than a part-time kitchen.
Questions to ask before booking
- What insurance they carry
- How VAT is shown on the quote
- What happens if part of the system can’t be accessed
- Whether the whole system is included, or only the parts that are easy to reach
Aftercare tips
How long the results last depends on use and care. We suggest:
- Make sure filters are seated properly
- Keep to the interval on the report
- Consider fitting panels where the report shows gaps
- Store the certificate with the fire risk assessment
Any section of duct we couldn’t reach is listed on the report and why. We can fit access panels so those sections are cleaned next time.
Keep the fan on throughout service. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.

Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Honest limits
A few issues sit outside what this work can do:
- A damper stuck open in the duct
- Parts of the duct with no way in
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
Not sure which it is? You can call 0345 646 2711 or email us and we will tell you honestly.
