Duct cleaning in Northfleet Green
Our technicians work in Northfleet Green on ductwork cleaning. Out-of-hours visits, a fixed quote and a written report with pictures on every job.
- Thick deposits at the bottom of a vertical duct
- A rancid smell from the extract duct
- Ductwork that has never been cleaned
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Keep access panels clear of stored items
- Ask us about extra access panels where sections can’t be reached
- Do not switch the extract off early
- Check readings when the menu changes
File the paperwork in the maintenance log. It’s the evidence an insurer or inspector may ask for, and the photos make the duct’s condition easy to see.
Some signs mean the duct needs attention sooner: drips from the ductwork, stale smells or a noisy fan. Testing will show whether any section has reached 500 microns.
Ductwork cleaning in Northfleet Green, done properly
No two duct runs are the same, in Northfleet Green or anywhere else. Some run a short distance to an outside wall, others climb several floors to the roof. The survey traces the route, so we know where to get in and how long it will take. If you have grease pooling at the foot of the riser and grease leaking from duct joints, we can put it right.
For a kitchen in or near Northfleet Green, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Do you need ductwork cleaning in Northfleet Green?
Ducts in Northfleet Green gather grease for the same reasons as ducts anywhere: hours of cooking, the type of food and how well the filters are kept. Under BESA guidance, the minimum interval is 3, 6 or 12 months, by daily cooking hours.
Look out for these warning signs:
- Hardened, baked-on grease in long horizontal runs
- Gaps where access panels were never fitted
- Duct runs with no cleaning record
- Grease pooling at the foot of the riser
A hospital like Gravesham Community Hospital, about 2.2 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Questions to ask before booking
- Whether a written report and photos are included
- Whether a survey comes first
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- When they can work, and whether that is outside your opening hours
The process
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes from a few hours to more than one visit, depending on duct length and access. We agree a date with you, plan the drive to Northfleet Green and turn up when the site is quiet.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Let us know about permits to work or site inductions
- Mention any parking or loading restrictions
How to get a quote
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To start, phone us on 0345 646 2711, or email photos.

How the job changes from site to site
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We clean it from the canopy side or through a nearby panel.
Multi-storey and shared buildings
A fire in a duct in a shared building can affect far more than one kitchen, so the responsible person has more reason to keep it clean. Your certificate and report give building managers the record they need.

What happens if it’s left?
A fire in a greasy duct is hard to reach and hard to stop. The duct can carry it to rooms, floors or roof spaces well away from the kitchen, so cleaning the duct is as important as cleaning the hood. It’s simpler to plan the work at Northfleet Green now than to arrange it in a hurry later.

Common questions in Northfleet Green
Is Northfleet Green 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.
Can a school canteen extract in Northfleet Green be done out of term time?
Yes, out-of-term visits are normal for schools. With about 15 schools and colleges on the FSA’s register within roughly a mile and a half of Northfleet Green, it pays to plan holiday dates ahead. Just ring 0345 646 2711 or email us with your term dates and we will plan around them.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
What’s the cleaning interval for extract ductwork?
BESA guidance sets minimum intervals by daily cooking hours: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Grease readings may show it needs doing sooner.
How do you protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
How do you clean inside the ductwork?
Through access panels along the duct. Thick deposits are removed by hand before degreasing, such as degreasers, hot water or steam.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
Multi-site and managed buildings
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Facilities teams in offices, schools and healthcare sites book us too across Kent. Larger estates can be phased building by building to keep disruption down.
What affects the quote in Northfleet Green
Sites vary more than people expect. The main factors:
- How easy every part is to reach
- When the work can happen, such as evenings, overnight or weekends
- How big the system is
- The condition of the system
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Problems your staff have spotted
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- When the site is open and when it’s quiet
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Where they cook under a canopy, grease does not stop at the filters: it settles along the duct and up the riser. Kent Fire and Rescue Service covers Northfleet Green. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Kitchens in Northfleet Green get their food hygiene inspections from Dartford council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up.
