Extract fan repair in Northfleet
Kitchens in Northfleet call us about extract fans and motors that are noisy, slow or dead, we diagnose the fault and give you a fixed quote to repair or replace it. When the fan gives up mid-service, our 24/7 emergency line is there. If you have a fan that won’t start at all and a squealing belt on start-up, we can help, from bearings, roof and wall fans and belts and pulleys onwards.
Extract fans on buildings in towns like Northfleet are often on a flat roof or an outside wall, exposed to wind and rain as well as grease. Belts, bearings and motors wear out in the end.
A written report with photos follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How the visit works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. The work itself takes anything from an hour or two to a full visit, depending on the fault. A few photos of the system and its access points help us plan a visit in Northfleet.
- We take details of the symptoms and book a time that suits the kitchen.
- On site, the fan is safely isolated.
- The fan and its controls are checked to pin down the fault.
- A fixed quote for the repair or replacement follows.
- We fix the fault and run the fan to check it.
Before we arrive

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. 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.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Different parts, different methods
Fan controls
Controls are checked as well as the fan itself, because a fan that won’t start is not always a failed motor.
Motors and bearings
The motor and its bearings work hardest. Hot, greasy air and long days wear them down.
Signs you need extract fan repair in Northfleet
Some grease always slips past the filters and reaches the fan. It builds up on the impeller blades unevenly, so the fan runs out of balance and the noise follows.
If you notice any of these, it’s worth a diagnosis:
- A fan that keeps cutting out
- A squealing belt on start-up
- An extract fan that rattles or knocks
- A fan worn beyond sensible repair
If you look after a church or hall kitchen near Church of All Saints, or anywhere in Northfleet, test the extract fan before a big event rather than on the day.
Questions to ask before booking
- How areas they can’t reach will be recorded
- Proof of insurance
- What records you will receive afterwards
- Exactly which parts of the system are covered
What staff can safely do
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Why act early in Northfleet
Left alone, vibration spreads its damage. It loosens fixings, strains duct connections and wears the housing, so a small repair can grow into a bigger one. A fresh certificate on file is the best thing to have when someone asks to see your records.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.
Why choose Duct Doctor in Northfleet
- Out-of-hours work and a 24/7 emergency line

Extract fan repair in Northfleet: local notes
Northfleet is within about 3 miles of the coast. Rust and grease together wear a fan out sooner, and coastal air speeds up the rust. Food Standards Agency data counts about 108 cafés, restaurants and staff canteens and about 59 sandwich bars and takeaways across Northfleet and its immediate surroundings (about a mile and a half). A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. In Northfleet, food businesses are inspected by environmental health officers from Gravesham council. Food hygiene rules expect food premises to have suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month.
Holidays are the time to replace a tired kitchen fan at schools such as Northfleet Technology College, rather than mid-term.
