Extract fan repair in Denvilles
Before anything is ordered, we diagnose. We look at the motor, the belts or direct drive, the impeller and the mountings, along with the fan’s controls. After that, you get a fixed price for what’s needed. We’re often asked to deal with an extract fan that rattles or knocks and a fan worn beyond sensible repair, on fan motors, belts and pulleys and bearings.
For a fan repair near Denvilles, we plan the journey and bring what the job is likely to need, based on what you tell us about the fan.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What happens if it’s left?
A struggling motor runs hotter and works harder. Every hour of strain takes its toll, and when it finally fails, it may take other parts with it. Early attention keeps the cost and disruption down. In a smaller place like Denvilles, a site that has to close is felt quickly.
We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or use the quote form, and we will talk you through it.

Do you need extract fan repair in Denvilles?
Fan bearings do not last for ever, especially in a hot, greasy airstream. As they wear, you hear a whine or a rumble, and if they’re left they can seize.
Signs it’s time to call us include:
- Vibration spreading from the fan into the ducts
- A worn or slipping fan belt
- Weak extraction and a smoky kitchen
- A fan that keeps cutting out
If you run a church or community hall kitchen, near St Thomas à Becket Church or elsewhere in Denvilles, an extract fan that rarely runs can seize or fail when it’s needed.
What your quote should include
- Whether the quote is based on a survey or pictures
- How areas they cannot reach will be recorded
- Whether they’re fully insured
- When they can work, and whether that is outside your opening hours

What else we do in Denvilles
What the work involves, part by part
Belt-driven fans
A squeal when the fan starts is a classic belt symptom. Belts are checked for wear, tension and alignment and renew them where necessary.
Direct-drive fans
Grease on the impeller unbalances a direct-drive fan quickly. Sometimes a clean is all it needs, if the bearings haven’t been damaged.
In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
What extract fan repair can’t fix
Some problems need a different service or another trade:
- Smells from the discharge that need odour control equipment
- Grease build-up in the rest of the extract system
- An extract system that was undersized from the start
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we will tell you honestly before you book.
Parts of the system we cover
- Bearings
- Kitchen extract fans
- Fan motors
- Fan housings
- Belts and pulleys
- Roof and wall fans
What affects the quote in Denvilles
The diagnosis comes before the price. The main factors are:
- The number of sites or systems
- Any permits to work or inductions
- Whether we need access equipment or extra panels
- The size of the system
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before any work starts.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room

Extract fans in Denvilles
Denvilles is within about 1 mile of the coast. A fan exposed to sea air needs its fixings and housing checked more often than one inland. There are about 51 cafés, restaurants and staff canteens and about 44 takeaways within 1.5 miles or so of the middle of Denvilles, according to the Food Standards Agency’s register. For any of them with a canopy, the extract fan is what keeps the kitchen usable. Kitchens in Denvilles get their food hygiene inspections from Havant council. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. Getting the fan running again is the priority.
If you cook near Warblington station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early. Holidays are the time to replace a tired kitchen fan at schools such as Warblington School, rather than mid-term.

What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes an hour or two to diagnose, then longer if parts or a new fan are needed. In a smaller place like Denvilles, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We take details of the symptoms and book a time that suits the kitchen.
- We isolate the fan before touching it.
- We diagnose the fault, checking the controls as well as the fan.
- A fixed quote for the repair or replacement follows.
- The work is done and the fan is tested running.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know about parking and loading
- Agree a time when the area can be out of use
Get a fixed quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
