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 on a regular cycle.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
About our extract fan repair in Grendon Underwood
Across Grendon Underwood, we deal with fan faults of every kind, from a squeal at start-up to a fan that will not run at all. The fault is diagnosed, quoted at a fixed price and put right or fit a replacement when it’s beyond repair. We are often asked to deal with an extract that vibrates through the ductwork and an extract fan that has stopped working, across belts and pulleys, kitchen extract fans and fan housings.
For a fan repair in or near Grendon Underwood, the more you tell us about the fan, the better the first visit: pictures of the fan, its rating plate and how to reach it all help.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

When something else is needed

- Problems with the gas supply or its interlock valve
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think.
Parts of the system we cover

Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
When to call us in Grendon Underwood
Not every problem is mechanical. A failed speed controller or a wiring fault can stop a fan, and a fan that will not start is not always a dead motor.
Any of these means the system needs a check-up:
- Vibration spreading from the fan into the ducts
- A worn or slipping fan belt
- An extract fan that rattles or knocks
- A fan that keeps cutting out
If you run a school kitchen, at a school such as Grendon Underwood Combined School or nearby, a fan that’s getting noisy is best repaired in the holidays before it fails in term.
Questions to ask before you book
- What hours they’ll be on site
- Which accreditations they hold, and whether you can check them
- What paperwork you get at the end
- Exactly which parts of the system are covered
Keeping the system healthy
So the system stays in good health:
- Keep the area around the fan controls clear
- Make sure every filter is in place and clean
- Make sure the fan is cleaned with the rest of the system
- Keep a record of any trips or stoppages
Once the fan is running smoothly, keep the filters clean. The less grease that reaches the fan, the longer its parts last and the quieter it runs.
Clogged filters make the fan strain. Keeping filters clean eases the strain and helps prevent overheating.
Your questions about extract fan repair in Grendon Underwood
Is Grendon Underwood within the area you cover?
Yes, we work in villages as well as towns, and Grendon Underwood is covered. The journey is planned ahead, so a few details about the route help.
Do you work overnight in Grendon Underwood?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Grendon Underwood needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Is it worth cleaning the extract while you are fixing the fan?
A repair deals with the fan, not the grease in the rest of the system. Grease on the fan typically means grease in the ducts and we can plan the two together.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Is there a survey before the work?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
Who is responsible for fire safety on the premises?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.
How we price extract fan repair
The price is fixed before any work begins. It takes into account:
- What state the system is in
- The times the site is available
- Whether several sites go on one quote
- Whether it’s a one-off visit or part of a schedule
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before we start.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Any access panels or hatches you can see
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, phone us on 0345 646 2711, or send details by email.
How the visit works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes part of a day for most faults, with a return visit if parts have to be ordered. If the van will struggle with a lane or gateway near Grendon Underwood, let us know and we will plan around it.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- Power to the fan is isolated before we open the housing.
- The impeller, bearings, belts or drive, motor and mounts are all inspected.
- We explain the fault and give you a fixed price for the fix.
- The repair or replacement is carried out and the fan is run and checked.
Before we arrive
- Have your last certificate or report to hand
- Allow time for equipment near the work to be turned off and cool down
- Move anything stored near the system
Ask for a quote
To get a fixed quote, ring 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We typically come back within one working day.
