Extract fan repair in Broad Colney
Wherever your kitchen is in Broad Colney, fan work means the extract has to be isolated, so we plan it around your service. We can work in the evening, overnight or at the weekend and there’s a 24/7 emergency line if the fan fails while you’re cooking. If you have a fan that keeps cutting out and a worn or slipping fan belt, we can help, from bearings, kitchen extract fans and fan motors onwards.
For a fan repair in or near Broad Colney, the more you tell us about the fan, the better the first visit: a photo of the fan, the details on its label and the access arrangements help us plan.
Duct Doctor has been trading since 2009, and we’re 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.

What else we do in Broad Colney
What extract fan repair can’t fix
We’d rather tell you now than book work that will not help, so here are the limits:
- 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
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly before you book.
What the work covers
- Belts and pulleys
- Fan housings
- Kitchen extract fans
- Bearings
- Roof and wall fans
- Fan motors
What the work involves, part by part
Belt-driven fans
In a belt-driven fan, the motor drives the impeller by belt. Worn belts squeal and slow the fan down, so we check the pulleys and bearings as well.
Direct-drive fans
Grease on the impeller unbalances a direct-drive fan quickly. Cleaning it can cure the noise, if the bearings haven’t been damaged.
How we price extract fan repair
There’s no set price list, because no two systems are the same. The quote depends on:
- Any permits to work or inductions
- The condition we find in the survey
- Whether it’s a one-off visit or part of a schedule
- Travel, parking and unloading
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and the price is agreed before any work starts.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- A few general shots of the system
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
How it works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes an hour or two to diagnose, then longer if parts or a new fan are needed. In a small place like Broad Colney, the journey is planned ahead and the visit arranged around the site’s hours.
- You describe the fault and we arrange a visit.
- We isolate the fan before touching it.
- The fan and its controls are checked to pin down the fault.
- A fixed quote for the repair or replacement follows.
- We fix the fault and run the fan to check it.
Preparing for the visit
- Let us know about permits to work or site inductions
- Dig out any earlier paperwork for the system
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Advice
Extract fan repair in Broad Colney: local notes
Food Standards Agency data counts about 15 cafés, restaurants and staff canteens and about 9 takeaways and sandwich shops within about 1.5 miles of central Broad Colney. For any of them with a canopy, the extract fan is what keeps the kitchen usable. Kitchens in Broad Colney get their food hygiene inspections from St Albans City council. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. That’s one more reason not to keep cooking with a broken fan. About 17 miles out from central London, Broad Colney is part of the South East area we work across. Evening, overnight and weekend visits are all possible.
A fan that rarely runs, like one in a hall kitchen near Church of St Peter or elsewhere in Broad Colney, can seize between uses.

Questions from Broad Colney
Do you work overnight in Broad Colney?
Yes, nights and weekends are routine for us. That way a site in Broad Colney does not have to lose a day’s trading. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you cover smaller places like Broad Colney?
Yes, Broad Colney is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. We usually quote within one working day, and emergencies are covered by our 24/7 line.
Do you look at the system first?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Do you recommend a next date?
Yes. The interval depends on how much the system is used and what we find and the report sets out why.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
Common problems we fix in Broad Colney
When filters clog and ducts fill with grease, the fan has to strain. A motor that strains runs hot, trips out or eventually burns out.
Look out for any of the following:
- A squealing belt on start-up
- A failed fan that needs a replacement
- A knocking noise from the extract fan
- A fan that won’t start at all
School kitchens can’t easily serve lunch without extraction, so if you look after one at a school like Saint Bernadette Catholic Primary School, fix a failing fan before term starts.

Leave it or put it right?
Left alone, vibration spreads its damage. It loosens fixings, strains duct connections and wears the housing and the eventual repair is larger. Rural sites can’t always move to another kitchen or room when something fails.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.
