Northfleet Green extract fan repair
Extract fan repair in Northfleet Green from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- An extract fan that has stopped working
- A fan rattling in its housing
- Vibration spreading from the fan into the ducts
Different parts, different methods
Roof and wall-mounted fans
Many kitchen extract fans sit on a roof or an outside wall. How easy the fan is to reach shapes the job, so we ask about it early.
Impellers and housings
Grease settles inside the fan housing as well as on the blades. Both are inspected and cleaning may be part of the fix.
Extract fan repair in Northfleet Green, done properly
If an extract fan in Northfleet Green is struggling or has stopped, we diagnose the fault and give you a fixed quote for the repair or the replacement. For a fan that fails during service, there’s a 24/7 emergency callout. We are often asked to deal with a fan rattling in its housing and an overheating extract motor, on roof and wall fans, fan housings and belts and pulleys.
A callout to a small place like Northfleet Green goes better when we know what we’re looking at: a photo of the fan, the details on its label and the access arrangements help us plan.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Why it’s worth doing now in Northfleet Green
Wherever the kitchen is, Northfleet Green included, the fan often sits on an outside wall or roof, so its noise doesn’t stay in the kitchen. Dealing with the fault brings the noise back down before neighbours notice. Rural sites can’t always move to another kitchen or room when something fails.
We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or use the quote form, and we’ll talk you through it.

How we price extract fan repair
The survey tells us what the work involves. We look at:
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
- The scale of the work
- Travel, parking and unloading
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
What to send for a quote
When you contact us, it’s useful to have:
- Your last certificate, test record or report
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
If you need extract fan repair in Northfleet Green, give us a ring on 0345 646 2711, or email photos. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. A fixed quote usually follows within one working day.
Aftercare tips
Think of this as the after-treatment advice, in brief:
- Keep the fan on a planned cleaning cycle
- Don’t wait for a noisy fan to stop
- Get a noisy fan checked rather than slowed down
- Don’t cook with gaps in the filter bank
Once we’re done, the extract is back in service. We clear up after ourselves and explain anything you need to know.
A fan that’s starting to make noise is giving you a warning. Getting it checked now means a planned repair rather than an emergency during service.
Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
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.
Landlords, agents and facilities managers
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.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Common questions in Northfleet Green
Do you work at weekends in Northfleet Green?
Yes, evening, overnight and weekend work is normal for us. That way a site in Northfleet Green doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Who inspects food businesses in Northfleet Green?
Kitchens in Northfleet Green are inspected by Dartford council’s environmental health officers. A note of when the fan failed and when it was fixed shows the problem was dealt with.
Do you recommend a next date?
Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Who is the responsible person?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.
Does the law say we must follow TR19?
No. TR19® itself isn’t law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
What extract fan repair looks like in Northfleet Green
Look up Northfleet Green on the FSA’s food hygiene register and you’ll find about 12 restaurants, cafés and canteens and about 18 takeaways in and around Northfleet Green, up to about a mile and a half out. Those that cook under a canopy rely on a fan that runs every hour they’re open. Northfleet Green is about 19 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. Food hygiene inspections in Northfleet Green are the job of Dartford council’s environmental health team. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. That’s one more reason not to keep cooking with a broken fan.
If you manage a school such as Painters Ash Primary School and the kitchen fan is getting louder, the next break is the time to deal with it. If you look after a church or hall kitchen near Church of St Nicholas, or anywhere in Northfleet Green, test the extract fan before a big event rather than on the day.
