About our extract fan repair in St Mary's
The extract fan is what pulls smoke, heat and steam out of the kitchen. When it starts to rattle, hum or slow down, the cooking area soon fills with heat and fumes. We find out why and put it right, by repairing the fan or replacing it. The work covers fan housings, kitchen extract fans and bearings, and people most often call us about a belt-driven fan that squeals and poor airflow at the canopy.
Kitchens around a smaller place like St Mary's often have fans fitted to a wall or roof years ago. An older fan that fails may be better replaced than repaired, and we’ll explain the options.
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 are fully insured.

How it works
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes anything from an hour or two to a full visit, depending on the fault, and we clear up before we go. Your opening hours decide when we come to St Mary's, not ours.
- We start with the symptoms, such as rattling, humming, slow running or a fan that will not start.
- With the fan safely isolated, we open it up for a proper look.
- The impeller, bearings, belts or drive, motor and mounts are all inspected.
- You get our diagnosis and a fixed quote to repair or replace.
- Once the work is done, we run the fan and check it’s steady and quiet.
Preparing for the visit
- Clear loose items from the work area
- Name a contact who can let us in at the agreed time
- Let us know how we reach the system, including roofs, risers and plant rooms

Advice
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Keep the fan on a planned cleaning cycle
- Note when the fan trips or cuts out
- Get a noisy fan checked rather than slowed down
- Do not wait for a noisy fan to stop
Once we are done, the extract is back in service. We clear up after ourselves and talk you through what we found.
A fan that’s starting to make noise is giving you a warning. Getting it checked now means a planned repair rather than an emergency during service.

What a clean will not put right
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Problems with the electrical supply to the fan (an electrician’s job)
- Odour complaints that need filtration rather than a fan repair
- Problems with the gas supply or its interlock valve
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we will tell you honestly before you book.
Parts of the system we cover

What staff can safely do
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.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Extract fan repair in St Mary's: local notes
St Mary's 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 data counts about 309 cafés, restaurants and staff canteens and about 109 takeaways and sandwich shops across St Mary's and its immediate surroundings (about a mile and a half). Those that cook under a canopy rely on a fan that runs every hour they’re open. Food hygiene inspections in St Mary's are the job of Southampton council’s environmental health team. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. Getting the fan running again is the priority.
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Hope Community School Southampton, fix a failing fan before term starts. Occasional-use kitchens, such as a hall kitchen near St Mary's Church or elsewhere in St Mary's, are where a stiff or seized fan can turn up. For a takeaway near Southampton Central station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.

Why it’s worth doing now in St Mary's
It can be tempting to turn the fan down to quieten it. That reduces extraction without fixing anything, and the fault carries on developing. Diagnosing the fault properly is the lasting answer. Even a site near St Mary's that’s only busy part of the week needs its system checked on 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.

Questions from St Mary's
Do you work overnight in St Mary's?
Yes, nights and weekends are routine for us. The site is handed back ready to open. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.
Is extract fan repair any different in a coastal place like St Mary's?
It can. St Mary's is within about 1 mile of the coast, and salt air speeds up corrosion. A fan housing that’s rusting near the coast can fail sooner, so it’s worth catching early.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
Will you fit a new fan if ours cannot be repaired?
We do. A replacement is matched to the system it’s going into, and you get a fixed quote first.
What if parts of the system cannot be reached?
Anything we cannot reach goes on the report, with pictures where possible, and we tell you what would make it reachable, for example new access panels.
Do I get a report after the visit?
Yes. It’s the record insurers and inspectors ask to see: a written, dated record with pictures of what we did and anything we couldn’t access.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What the work involves, part by part
Fan controls
Every fan has controls, from a speed controller to an isolator. When they fail, the fan may not start or may run at the wrong speed.
Motors and bearings
If the motor runs hot or keeps tripping, something’s wrong. It may be straining against blocked filters or ducts or the motor may be near the end of its life.
