About our extract fan repair in Knapp
Working on a fan in Knapp means switching the extract off first, so the job is fitted around the kitchen’s hours. Evenings, overnight and weekends are all possible, and a fan that dies mid-service can go straight to our 24/7 line. Typical jobs include an old fan that needs replacing and a fan that keeps cutting out, across kitchen extract fans, fan housings and roof and wall fans.
A callout to a small place like Knapp goes better when we know what we’re looking at: pictures of the fan, its rating plate and how to reach it all help.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Part by part
Fan controls
Where the fault is in the building’s electrical supply, an electrician is needed. If that’s the cause, we’ll say so so you know who to call.
Belt-driven fans
With belts and pulleys, there’s more to wear. That means more to check, but often a simpler repair.
Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
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.
Why deal with it now?
In kitchens with an interlocked gas supply, no extract can mean no cooking. Even without an interlock, cooking without extraction isn’t sensible, so a failing fan is worth dealing with early. It’s simpler to plan the work at Knapp now than to arrange it in a hurry later.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

What a clean will not put right
In fairness, some problems need a different fix:
- Problems with the gas supply or its interlock valve

Your questions about extract fan repair in Knapp
Who inspects food businesses in Knapp?
In Knapp, it’s Test Valley council that carries out food hygiene inspections. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
Is there an emergency callout for extract fans in Knapp?
We run a 24/7 emergency line for failed extract fans, and Knapp is part of our area. Phone 0345 646 2711 and we’ll talk through the fault and access. A photo of the fan’s rating plate helps.
Do you survey before quoting?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
Is repair an option before replacing the whole fan?
It depends on the fault. After diagnosing, we explain whether it can be repaired and quote a fixed price for the option you choose.
What will a fan repair or replacement cost?
It depends on the fault, the parts and the access. After diagnosing, you get a fixed quote before any work starts.
Does a fan repair include cleaning the ductwork?
Often it makes sense to do both. A full clean takes in the whole extract, including the fan, with a certificate and photo report.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we are fully insured.
What affects the cost of extract fan repair
Sites vary more than people expect. The main factors:
- The condition we find in the survey
- How easy every part is to reach
- A single visit or a regular plan
- Any permits to work or inductions
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- Wide photos of the system and the area around it
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
- Any access panels or hatches you can see
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Extract fan repair in Knapp: local notes
Kitchens in Knapp get their food hygiene inspections from Test Valley council. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. So a failed fan is worth fixing before the next service, not the next month.
If you manage a school such as Ampfield Church of England Primary School and the kitchen fan is getting louder, the next break is the time to deal with it. Occasional-use kitchens, such as a hall kitchen near Church of St Mark or elsewhere in Knapp, are where a stiff or seized fan can turn up.

Managing agents and facilities teams in Knapp
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.

The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, which takes a few hours for most repairs, longer for a full fan replacement. A few pictures of the system help us make the most of a visit to a place like Knapp.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- The fan is isolated and opened up so we can see inside.
- 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.
How to prepare
- Name a contact who can let us in at the agreed time
- Mention any sign-in, permit or induction we need
- Let us know how we reach the system, including roofs, risers and plant rooms
