Extractor fan repair in Woolmer Green
Extract fan repair for Woolmer Green, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- A fan that whines, hums or grinds
- A fan that won’t start at all
- Poor airflow at the canopy
Part by part
Belt-driven fans
In a belt-driven fan, the motor drives the impeller by belt. Belts wear, stretch and slip, so we check the pulleys and bearings as well.
Impellers and housings
The impeller is the bladed wheel that moves the air. Grease on it throws it out of balance and cause vibration.
How we handle extract fan repair in Woolmer Green
A faulty fan does not always mean a new one. Sometimes cleaning the impeller or renewing worn parts is enough, and that is what we’ll recommend. Where the motor has burnt out or the unit is past saving, a replacement suited to the system goes in. If you have a squealing belt on start-up and poor airflow at the canopy, we can put it right, from belts and pulleys, fan housings and kitchen extract fans onwards.
In a village or hamlet like Woolmer Green, the kitchens with extract fans are few, wherever there are any. When one fails, the cooking stops, and our 24/7 emergency line covers rural addresses too.
We have been trading since 2009, as 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.

Common problems we fix in Woolmer Green
Grease that gets past the filters ends up on the fan. It builds up on the impeller blades unevenly, so the fan runs out of balance and the noise follows.
Common reasons sites call us are:
- A fan running too slowly to clear the kitchen
- A motor that trips out or overheats
- A whining or grinding extract motor
- A dead fan motor
If you look after a church or hall kitchen near Church of St Michael and All Angels, or anywhere in Woolmer Green, test the extract fan before a big event rather than on the day.

For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
What we do, step by step
We turn up 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 anything from an hour or two to a full visit, depending on the fault. A quick note on how to find the site and where to park makes a visit to Woolmer Green run smoothly.
- We start with the symptoms, such as rattling, humming, slow running or a fan that won’t start.
- The fan is isolated and opened up so we can see inside.
- 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.
- We fix or replace the fan, then test it running before we leave.
Before we arrive
- Find the previous report, if there is one
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet
How to get a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Common questions in Woolmer Green
Who do I call if an extract fan fails in Woolmer Green?
Day or night, a failed fan in Woolmer Green can be reported on our emergency line. Call 0345 646 2711 and tell us what the fan is doing, or not doing. A photo of the fan’s rating plate helps.
Can you get to a site in Woolmer Green?
Yes, Woolmer Green is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
What do you do with what you remove?
It leaves the site with us when we go. While we work, it’s kept contained so the area stays clean.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
How much time does a fan repair need?
That depends on what’s wrong, but as a guide it takes a few hours on site, depending on the fault and the access to the fan. You will know more once we’ve found the fault.
What happens if you cannot reach some of it?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.

Honest limits
A few issues sit outside what this work can do:
- Grease build-up in the rest of the extract system
- An extract system that was undersized from the start
- Odour complaints that need filtration rather than a fan repair
If in doubt, phone us on 0345 646 2711, or email photos and we’ll say what we think before you book.
Parts of the system we cover
- Belts and pulleys
- Fan motors
- Fan housings
- Roof and wall fans
- Kitchen extract fans
- Bearings
In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.

- What state the system is in

What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before any work starts.
