Extract fan repair in Merrow, done properly
Not every failed fan needs replacing. Often a clean, a new belt or new bearings brings it back and we will say so. When a fan is worn beyond sensible repair, we fit a replacement matched to the duct and the kitchen. If you have a belt-driven fan that squeals and a humming noise from the fan motor, we can put it right, from belts and pulleys, fan motors and fan housings onwards.
In a smaller place like Merrow, a failed extract fan means a closed kitchen, and a closed kitchen loses trade. Our 24/7 emergency line is there for exactly that.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
For landlords and multi-site operators
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
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.
What extract fan repair looks like in Merrow
Food Standards Agency data counts about 16 restaurants, cafés and works canteens and about 4 takeaways in Merrow and the streets around it, up to about 1.5 miles out. For any of them with a canopy, the extract fan is what keeps the kitchen usable. About 26 miles out from central London, Merrow is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you. Kitchens in Merrow get their food hygiene inspections from Guildford council. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. So a failed fan is worth fixing before the next service, not the next month.
If you run a school kitchen, at a school such as Bushy Hill Junior School or nearby, a fan that’s getting noisy is best repaired in the holidays before it fails in term.
Merrow is about 2 miles east of Guildford, in Surrey. Merrow gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with pictures. Merrow is one of 395 towns, villages and districts in Surrey where we work for commercial clients.
Postcode districts we cover here for extract fan repair: GU1 and GU4. If you need extract fan repair at premises on Park Lane, Grove Road and Wykeham Road or anywhere close by, our technicians can take on the work. Nearby, we also carry out extract fan repair in Burpham (1 mile north-west), Abbotswood (1 mile west), West Clandon (2 miles north-east), Guildford (2 miles west) and Chilworth (2 miles south).

Local landmarks in Merrow
We work in commercial kitchens and buildings around St Peter's Catholic School, St Peter's Catholic School and Riverside Park and the streets around them. Merrow’s nearest station is Clandon station, roughly 1.6 miles north-east. Other landmarks nearby include Guildford Castle (2.1 miles south-west) and Surrey Infantry Museum (0.6 miles north-east). For a walk, there’s St Martha's Hill and Colyer's Hanger and Silent Pool.
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. A repair booked now is simpler than an emergency later. It’s easy to lose track of when the work was last done on a quieter site.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

Common questions in Merrow
Which council inspects kitchens in Merrow?
Kitchens in Merrow are inspected by Guildford council’s environmental health officers. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
Will you come out to Merrow?
Yes, we work in villages as well as towns, and Merrow is covered. Photos of the system and directions to the site help us plan the visit.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Can you supply and fit a replacement fan?
Yes, when repair doesn’t make sense. The replacement has to suit the ductwork and the cooking before recommending a unit.
What should go in our maintenance log?
Anything that proves the system is maintained: our reports and photos, any certificates and your in-house logs. One maintenance log per site keeps it simple.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Different parts, different methods
Motors and bearings
If the motor runs hot or keeps tripping, something’s wrong. The cause might be grease restricting the airflow, or the motor itself may be failing.
Fan controls
Every fan has controls, from a speed controller to an isolator. When they fail, the fan may not start or may run at the wrong speed.
What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes an hour or two to diagnose, then longer if parts or a new fan are needed. Evenings, weekends or a closed day all work for a site in a place like Merrow.
- We agree a time to attend, out of hours if needed.
- We isolate the extract and open the fan housing.
- We inspect every moving part and the fixings.
- We explain the options and quote a fixed price.
- We complete the work and check the fan runs smoothly.
How to prepare
- Let us know about permits to work or site inductions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Dig out any earlier paperwork for the system

What else we do in Merrow
What we are called out for in Merrow
When filters clog and ducts fill with grease, the fan has to strain. An overworked motor overheats and may cut out or fail.
Any of these means the system needs a check-up:
- A belt-driven fan that squeals
- Poor airflow at the canopy
- An overheating extract motor
- A failed fan that needs a replacement
If you look after a church or hall kitchen near Church of St John the Evangelist, or anywhere in Merrow, test the extract fan before a big event rather than on the day.
