Extractor fan repair in Portsmouth
Extract fan repair and replacement for commercial sites in Portsmouth. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- A fan rattling in its housing
- A worn or slipping fan belt
- A fan that won’t start at all
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Keep the emergency number where staff can see it
- Write down when the fan misbehaves
- Don’t turn the fan down to hide a noise
- Make sure the isolator and controls are easy to reach
Once we’re done, the extract is back in service. We clear up after ourselves and explain anything you need to know.
Noise is normally the first sign of a fan problem. Booking a check at this stage keeps it a planned job rather than an emergency during service.
About our extract fan repair in Portsmouth
Grease is hard on extract fans. Deposits on the impeller throw it out of balance, which shakes the bearings and mountings. So when we repair extract fan, we look at the grease too and can arrange a TR19® clean of the whole system at the same time. The work covers belts and pulleys, bearings and kitchen extract fans, and people most often call us about a fan that won’t start at all and a knocking noise from the extract fan.
A kitchen in a busy place like Portsmouth may run its fan from opening to close, which wears out belts, bearings and motors. Grease on the impeller unbalances it and strains the motor.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Why deal with it now?
Fan noise tends to get worse, not better. Worn bearings can seize without much warning, and that often happens mid-service. A repair booked now is simpler than an emergency later. A gap in the records is hard to explain after an incident, so it pays to keep the work current.
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before any work starts.
Why choose Duct Doctor in Portsmouth

Part by part
Roof and wall-mounted fans
Noise from an outside fan can carry beyond the kitchen. Loose fixings and worn mounts are often the cause.
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.
Common questions in Portsmouth
Which council inspects kitchens in Portsmouth?
Kitchens in Portsmouth are inspected by Portsmouth council’s environmental health officers. If the extract fan has failed, it’s worth having the repair booked, and the details to hand, before an officer visits.
Can you come to Portsmouth after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Portsmouth keeps running as normal. Tell us your opening hours when you ask for a quote.
Do you cover Portsmouth?
Yes. Portsmouth is part of the area we cover, within the South East and London area we cover.
Do you recommend a next date?
Yes. The report recommends when the next visit should be, based on use and what we found.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Do we lose a day’s trading?
Not typically. The area we’re working in has to be out of use while we are there, so the visit goes in a quiet slot.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Common problems we fix in Portsmouth
Blocked filters and greasy ducts make the fan work harder. A motor that strains runs hot, trips out or eventually burns out.
Keep an eye out for any of the following:
- An old fan that needs replacing
- A squealing belt on start-up
- A motor that trips out or overheats
- An extract fan that rattles or knocks
If you run a church or community hall kitchen, near St Wilfrid or elsewhere in Portsmouth, an extract fan that rarely runs can seize or fail when it’s needed.

What else we do in Portsmouth
Extract fans in Portsmouth
Portsmouth is within about 1 mile of the coast. Motor mounts, bolts and housings on outdoor fans corrode faster close to the coast. Food Standards Agency records list about 262 restaurants, cafés and works canteens and about 152 takeaways within roughly a mile and a half of the centre of Portsmouth. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. It’s Portsmouth council that sends environmental health officers to food businesses in Portsmouth. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. A kitchen without a working fan has a problem to fix quickly.
For a takeaway near Fratton station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7. For school kitchens, at schools like Manor Infant School for example, a planned fan repair in the holidays avoids losing lunches in term time.

Fixed quotes for extract fan repair in Portsmouth
The diagnosis comes before the price. We look at:
- Travel, parking and unloading
- What state the system is in
- The size of the system
- The number of sites or systems
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
What we need to know
You don’t need the technical terms. It helps if you can send:
- The paperwork from the last visit, if you have it
- A few general shots of the system
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price, before we start.
How the visit works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes a few hours on site, depending on the fault and the access to the fan. A big building in Portsmouth does not have to shut: the work can be spread across a few evenings or weekends.
- We take details of the symptoms and book a time that suits the kitchen.
- On site, the fan is safely isolated.
- We diagnose the fault, checking the controls as well as the fan.
- A fixed quote for the repair or replacement follows.
- The work is done and the fan is tested running.
How to prepare
- Tell us where we can park and unload
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or email us.

What extract fan repair can’t fix
In fairness, there are a few things this work won’t fix:
- Grease throughout the ductwork, which needs a full TR19 clean
- Ductwork designed too small for the kitchen’s cooking
- Gas interlock faults that a Gas Safe registered engineer must deal with
Not sure which it is? You can call 0345 646 2711 or email us and we will tell you honestly.
