Extract fan repair in Sleaford, done properly
Working on a fan in Sleaford 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. If you have a squealing belt on start-up and a dead fan motor, we can put it right.
In a village or hamlet like Sleaford, the kitchens with extract fans are few, wherever there are any. A failed fan stops the kitchen, and our 24/7 emergency line covers rural addresses too.
We are 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, trading since 2009.

Sleaford questions
What if my kitchen extract fan stops in Sleaford at night?
We run a 24/7 emergency line for failed extract fans, and Sleaford is part of our area. Use 0345 646 2711, our emergency number, at any time. A photo of the fan’s rating plate helps.
Will you come out to Sleaford?
Yes, we work in villages as well as towns, and Sleaford is covered. Photos of the system and directions to the site help us plan the visit.
Why is our extract fan so noisy?
It can be one of a few things, including bearings, belts, grease and mounts. The safest step is a proper diagnosis before it leads to a breakdown.
Will you fit a new fan if ours cannot be repaired?
Yes. A replacement is matched to the system it’s going into, and you get a fixed quote first.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and pictures.
Different parts, different methods
Direct-drive fans
An impeller coated in grease vibrates straight into the motor bearings. Sometimes a clean is all it needs as long as the bearings are still sound.
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 may be near the end of its life.
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
What we do, step by step
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes a few hours for most repairs, longer for a full fan replacement. Seeing the system in pictures first means the trip to Sleaford can be planned properly.
- A visit is booked, in the evening or overnight if that suits.
- The extract is switched off and the fan opened up.
- We inspect every moving part and the fixings.
- You hear whether repair or replacement makes sense, with a fixed quote.
- We complete the work and check the fan runs smoothly.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about permits to work or site inductions
How to get a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
Advice
Also in Sleaford
When a fan fails in Sleaford
There are about 4 restaurants, cafés and canteens within roughly a mile and a half of the centre of Sleaford, according to the Food Standards Agency’s register. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. It’s East Hampshire council that sends environmental health officers to food businesses in Sleaford. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. A kitchen without a working fan has a problem to fix quickly. We cover Sleaford, about 41 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
Occasional-use kitchens, such as a hall kitchen near Church of All Saints or elsewhere in Sleaford, are where a stiff or seized fan can turn up. If you run a school kitchen, at a school such as Mill Chase Academy or nearby, a fan that is getting noisy is best repaired in the holidays before it fails in term.

Why deal with it now?
Wherever the kitchen is, Sleaford included, the fan often sits on an outside wall or roof, so its noise doesn’t stay in the kitchen. Dealing with the fault brings the noise back down before it becomes a nuisance. If the system at a site near Sleaford fails, there may be nowhere nearby to move to.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before work begins.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
