Extract fan repair for kitchens and businesses in Crayford
Grease and fans do not mix. Deposits on the impeller throw it out of balance, which shakes the bearings and mountings. That’s why we check the grease whenever we work on a fan and can arrange a TR19® clean of the whole system at the same time. The work covers roof and wall fans, bearings and fan housings, and people most often call us about a humming noise from the fan motor and a failed fan that needs a replacement.
In a smaller place like Crayford, a failed extract fan means a closed kitchen, and a closed kitchen loses trade. Our 24/7 emergency line is there for exactly that.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Keeping the system healthy
Once we have finished, these simple steps help:
- Write down when the fan misbehaves
- Report new noises from the fan early
- Make sure the isolator and controls are easy to reach
- Get a noisy fan checked rather than slowed down
Your kitchen can get back to normal as soon as the fan is running. We clear up after ourselves and talk you through what we found.
When filters block, the fan works harder. Keeping filters clean eases the strain and protects the motor.
Leave it or put it right?
An overloaded motor is under constant strain. Every hour of strain takes its toll and a burnt-out motor is a bigger job than a worn belt. Catching it early keeps the repair small. Light use slows the build-up but does not stop it.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before we start.

What the work involves, part by part
Belt-driven fans
Belt drives have more moving parts than direct-drive fans. That means more to check, but often a simpler repair.
Motors and bearings
Rumbling and grinding normally come from the bearings. We diagnose whether it’s the bearings or the motor itself before recommending a fix.
Questions from Crayford
Who inspects food businesses in Crayford?
Kitchens in Crayford are inspected by Bexley council’s environmental health officers. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
Can you come to Crayford after we close?
Yes, nights and weekends are routine for us. It means the site in Crayford keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Will I get paperwork for my records?
Yes. It’s the record insurers and inspectors ask to see: a written, dated record with photos of what we did and anything we couldn’t access.
Are you accredited?
We’re 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.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
Should the fan be cleaned as well as repaired?
The ductwork is a separate job. We’ll point out grease where we find it, so you can decide whether to book a TR19 clean.
Which records should we keep?
Everything that shows the system is looked after: reports, certificates, pictures and your own cleaning or check logs. A single log for each site works best.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
The process
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes part of a day for most faults, with a return visit if parts have to be ordered. For a site near Crayford, the work is booked around your opening hours, evenings and weekends included.
- We start with the symptoms, such as rattling, humming, slow running or a fan that won’t start.
- Power to the fan is isolated before we open the housing.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
- The repair or replacement is carried out and the fan is run and checked.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Dig out any earlier paperwork for the system
- Tell us the best time to work, such as after service or at a weekend

Fixed quotes for extract fan repair in Crayford
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Site rules, permits and inductions
- A single visit or a regular plan
- How easy every part is to reach
- The size of the system
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
What to send for a quote:
- Problems your staff have spotted
- Where the site is and what kind of site it is
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Do you need extract fan repair in Crayford?
Some faults are in the controls rather than the fan. A failed speed controller or a wiring fault can stop a fan so we check the controls before blaming the motor.
The symptoms we are asked about most include:
- A dead fan motor
- An extract that vibrates through the ductwork
- An overheating extract motor
- A fan running too slowly to clear the kitchen
If you cook near Crayford station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early.
Questions to ask before booking
- What’s included in the scope, part by part
- How areas they cannot reach will be recorded
- If the quote is a fixed price or an estimate
- Whether VAT is included
Extract fan repair in Crayford: local notes
Food Standards Agency records list about 90 restaurants, cafés and works canteens and about 65 takeaways in Crayford and the streets around it, up to about 1.5 miles out. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. About 12 miles out from central London, Crayford is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included. Kitchens in Crayford get their food hygiene inspections from Bexley council. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. That makes a fan repair urgent rather than something to put off.
If you manage a school such as Wentworth Primary School and the kitchen fan is getting louder, the next break is the time to deal with it. Hall kitchens near Church of St Paulinus, or anywhere around Crayford, often use their fans only now and then, and an idle fan can stick.
