When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what extract fan repair will not do:

- Problems with the electrical supply to the fan (an electrician’s job)
- Ductwork designed too small for the kitchen’s cooking
If in doubt, give us a ring on 0345 646 2711 or send us an email and we’ll say what we think before you book.

Extract fan repair for kitchens and businesses in Brookmans Park
A faulty fan doesn’t always mean a new one. Sometimes cleaning the impeller or renewing worn parts is enough and we’ll say so. When a fan is worn beyond sensible repair, a replacement suited to the system goes in. If you are dealing with a fan running too slowly to clear the kitchen and an overheating extract motor, we can put it right, from roof and wall fans, belts and pulleys and kitchen extract fans onwards.
A callout to a small place like Brookmans Park goes better when we know what we are looking at: photos of the fan, its rating plate and how to reach it all help.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Fixed quotes for extract fan repair in Brookmans Park
There’s no set price list, because sites vary so much. The quote depends on:
- Where the site is and how we reach it
- The condition we find in the survey
- The size of the system
- Access, including roofs, risers and ceiling voids
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.
What we need to know
You don’t need the technical terms. Just send:
- Problems your staff have spotted
- Photos showing the whole system and its surroundings
- The postcode and the type of business
- The times we could work without disrupting the site
To help us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Then ring 0345 646 2711 or use the quote form.
Aftercare tips
So the system stays in good health:
- Avoid lowering the speed to quieten a fault
- Don’t wait for a noisy fan to stop
- Note when the fan trips or cuts out
- Make sure staff know who to call if the fan fails
If parts have to be ordered, we tell you how the kitchen can carry on in the meantime. We then come back and fit them at a time that suits your service.
A slipping belt or a loose mount is a small job. Ignored, they can lead to bigger failures, so it’s worth acting early.
Questions from Brookmans Park
Who do I call if an extract fan fails in Brookmans Park?
Day or night, a failed fan in Brookmans Park can be reported on our emergency line. Call 0345 646 2711 and tell us what the fan is doing, or not doing. Let us know whether the fan is silent, noisy or tripping the power.
Do you cover smaller places like Brookmans Park?
Yes, we work in villages as well as towns, and Brookmans Park is covered. A survey first, from photos or a visit, means we arrive with the right kit.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
Will we have to shut during the visit?
Not usually. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
Do you recommend a next date?
Yes. The report recommends when the next visit should be, based on use and what we found.
What will a fan repair or replacement cost?
Every fan job is priced once we know the fault. Repair, parts or a full replacement all cost differently, so give us a ring on 0345 646 2711 or email us and we’ll arrange a diagnosis.
Is repair an option before replacing the whole fan?
In many cases, yes. Many faults are fixed by cleaning the impeller or renewing worn parts and we only recommend replacement when repair doesn’t make sense.
Managing agents and facilities teams in Brookmans Park
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

- An extract fan that has stopped working
- A fan that whines, hums or grinds
- A worn or slipping fan belt

What the work involves, part by part
Impellers and housings
The impeller is the bladed wheel that moves the air. Grease on it throws it out of balance and make it shake.
Direct-drive fans
Direct-drive fans have the impeller mounted straight on the motor. There are no belts, so faults tend to be in the motor, bearings or impeller.
