Extract fan repair around Windmill Hill
Windmill Hill is within about 2 miles of the coast. Salt air is hard on fan housings, motors and fixings on roofs and outside walls. There are about 108 restaurants, cafés and works canteens and about 74 takeaways across Windmill Hill and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Environmental health officers from Gravesham council inspect food businesses in Windmill Hill. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. Getting the fan running again is the priority.
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Wrotham Road Primary School, fix a failing fan before term starts. If you run a church or community hall kitchen, near Christ Church Milton or elsewhere in Windmill Hill, an extract fan that rarely runs can seize or fail when it’s needed.

Extract fan repair in Windmill Hill
Extract fan repair starts with a diagnosis. Noise can come from grease on the impeller, worn bearings or a slipping belt; a dead fan can point to the motor or its controls. You hear what we’ve found before any work goes ahead. The work covers kitchen extract fans, fan housings and fan motors, and common reasons people get in touch are an old fan that needs replacing and a fan that whines, hums or grinds.
Around a place like Windmill Hill, a pub, café or care home kitchen with a failed fan can’t carry on cooking as normal. Our 24/7 emergency line is there for exactly that.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Part by part
Impellers and housings
Grease settles inside the fan housing as well as on the blades. We check both, and cleaning can form part of the repair.
Motors and bearings
Rumbling and grinding typically come from the bearings. We find out whether the bearings or the motor is at fault before recommending a fix.
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Windmill Hill: your questions answered
Do you cover smaller places like Windmill Hill?
Yes. Villages and rural sites across the South East are part of our work, Windmill Hill included. The journey is planned ahead, so a few details about the route help.
Does the sea air around Windmill Hill make a difference to extract fan repair?
It can. Salt air reaches Windmill Hill, which is within about 2 miles of the coast, and it speeds up rust. A fan housing that’s rusting near the coast can fail sooner, so it’s worth catching early.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
What do you do with what you remove?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
Can you supply and fit a replacement fan?
Yes. Where a fan is beyond repair, we replace it with one suited to the duct and the kitchen with a fixed price agreed before work begins.
What does TR19 mean?
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.
Signs you need extract fan repair in Windmill Hill
Fans everywhere, Windmill Hill included, live in a hard environment: hot, greasy, damp air for hours on end. Moisture can rust housings and fixings, and age catches up with every fan in the end.
Signs it’s time to call us include:
- A fan shaking on its mountings
- A knocking noise from the extract fan
- A fan worn beyond sensible repair
- A squealing belt on start-up
For a takeaway near Gravesend station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.

Managing agents and facilities teams in Windmill Hill

The cost depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so you know where you stand.

Keeping the system healthy
After the visit, a few habits help the work last:
- Tell us about a new rattle or whine right away
- Save our number for the 24/7 emergency line
- Keep a record of any trips or stoppages
- Make sure every filter is in place and clean
Once the fan is running smoothly, keep the filters clean. Less grease on the impeller means less wear and the quieter it runs.
The fan is part of every full TR19 clean. Keeping grease off the impeller is one of the simplest ways to protect it and that means less wear.
