Wilstone extract fan repair
Professional extract fan repair in and around Wilstone, timed so the site keeps working and signed off in writing with photos.
- An extract fan that has stopped working
- A fan rattling in its housing
- A failed fan that needs a replacement
Multi-site and managed buildings
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 on a regular cycle.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
How we handle extract fan repair in Wilstone
Wherever your kitchen is in Wilstone, fan work means the extract has to be isolated, so the job is fitted around the kitchen’s hours. We can work in the evening, overnight or at the weekend, and a fan that dies mid-service can go straight to our 24/7 line. The work covers bearings, belts and pulleys and fan motors, and people most often call us about a belt-driven fan that squeals and vibration spreading from the fan into the ducts.
For a fan repair in or near Wilstone, the more you tell us about the fan, the better the first visit: photos of the fan, its rating plate and how to reach it all help.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Extract fan repair around Wilstone
The FSA’s food hygiene register shows about 4 restaurants, cafés and canteens in Wilstone and the streets around it, up to about 1.5 miles out. Those that cook under a canopy rely on a fan that runs every hour they’re open. In Wilstone, food businesses are inspected by environmental health officers from Dacorum council. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. A kitchen without a working fan has a problem to fix quickly. About 34 miles out from central London, Wilstone is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
For school kitchens, at schools like Marsworth Church of England Infant School for example, a planned fan repair in the holidays avoids losing lunches in term time.

Why deal with it now?
A noisy fan rarely fixes itself. Worn bearings can seize without much warning and the fan may stop when you’re busiest. Sorting it while it still runs is far easier to plan. Our emergency line runs 24/7, but a planned visit to Wilstone is calmer for everyone.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before we start.

The process
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the extract fan repair, tidy up and leave you the report. The visit itself takes a few hours on site, depending on the fault and the access to the fan. A few photos of the system help us make the most of a visit to a place like Wilstone.
- We ask what the fan is doing, from noise and vibration to a full stop.
- With the fan safely isolated, we open it up for a proper look.
- We check the motor, bearings, drive, impeller and mountings.
- You get our diagnosis and a fixed quote to repair or replace.
- We fix or replace the fan, then test it running before we leave.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Find the previous report, if there is one
- Agree a time when the area can be out of use
How to get a quote
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.

How the job changes from site to site
Motors and bearings
Motors and bearings take the most strain in a kitchen extract fan. Hot, greasy air and long days wear them down.
Roof and wall-mounted fans
An external fan’s rattle can be heard outside. It’s often down to loose mounts or worn bearings.
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Make sure the fan is cleaned with the rest of the system
- Write down when the fan misbehaves
- Never run the extract with filters missing
- Save our number for the 24/7 emergency line
Before we leave, the fan is run and checked. We explain the fault and the fix, and anything else we noticed is pointed out.
When filters block, the fan works harder. Changing or cleaning them on time takes load off the motor and protects the motor.
What a clean won’t put right
Some problems need a different service or another trade:
- A greasy canopy and duct that a fan repair will not touch
- An extract system that was undersized from the start
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think.

FAQs for Wilstone
Can you come out to a failed extract fan in Wilstone out of hours?
We run a 24/7 emergency line for failed extract fans, and Wilstone is part of our area. Use 0345 646 2711, our emergency number, at any time. Tell us where the fan is and how to reach it.
Is Wilstone within the area you cover?
Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.
Does a fan repair include cleaning the ductwork?
Doing both together is often sensible. A TR19 clean covers the canopy, plenum, ductwork and fan and comes with a TR19 certificate and photo report.
What happens if you can’t reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Is TR19 cleaning required by law?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
How much does an extract fan repair cost?
The price depends on the diagnosis. After we’ve checked the fan, we give you a fixed price for the repair or the replacement.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Do you recommend a next date?
Yes. How often depends on use and condition, and we explain the reasoning on the report.
Do you need extract fan repair in Wilstone?
Any kitchen that cooks for long hours works its fan hard, in Wilstone or anywhere else. Belts on a belt-driven fan stretch and wear and a slipping belt means slower fan speed and weaker extraction.
Any of these means the system needs a check-up:
- Weak extraction and a smoky kitchen
- An extract fan that has stopped working
- A belt-driven fan that squeals
- An extract that vibrates through the ductwork
If you run a church or community hall kitchen, near St Cross or elsewhere in Wilstone, an extract fan that rarely runs can seize or fail when it’s needed.
