About our extract fan repair in Russell Hill
Everything a kitchen extract does depends on the fan. Once it turns noisy, sluggish or stops altogether, the cooking area soon fills with heat and fumes. We find out why and put it right with a repair or a replacement. If you are dealing with an overheating extract motor and a dead fan motor, we can help.
Replacing a fan in a London building often means working at height or in a tight plant space, and in Russell Hill, parking and lifting are part of that. Repairs can be done out of hours so the kitchen keeps trading.
Duct Doctor has been trading since 2009, as 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 staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
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.
Questions from Russell Hill
Can you come out to a failed extract fan in Russell Hill out of hours?
We run a 24/7 emergency line for failed extract fans, and Russell Hill is part of our area. Call 0345 646 2711 and tell us what the fan is doing, or not doing. A photo of the fan’s rating plate helps.
Does London parking affect a job in Russell Hill?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, usually makes it simpler.
What should go in our maintenance log?
Each report and certificate we give you, kept together in your maintenance log, along with your own cleaning log. BESA says certificates should show the date, location and technician.
Who has the legal duty for fire safety?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Every site has its own report.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
Should the fan be cleaned as well as repaired?
Often it makes sense to do both. A full clean takes in the whole extract, including the fan and comes with a TR19 certificate and photo report.
What accreditations do you have?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Extract fan repair around Russell Hill
Food Standards Agency data counts about 196 restaurants, cafés and works canteens and about 104 sandwich bars and takeaways in Russell Hill and the streets around it, up to about 1.5 miles out. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. London extract fans are often at the end of long duct runs, on roofs or in basements. In Russell Hill, food businesses are inspected by environmental health officers from Sutton council. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. A kitchen without a working fan has a problem to fix quickly.
School kitchens can’t easily serve lunch without extraction, so if you look after one at a school like Wallington Primary Academy, fix a failing fan before term starts. If you look after a church or hall kitchen near St. Paul's, or anywhere in Russell Hill, test the extract fan before a big event rather than on the day.

Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Don’t wait for a noisy fan to stop
- Make sure staff know who to call if the fan fails
- Avoid lowering the speed to quieten a fault
- Do not cook with gaps in the filter bank
If the fan had grease on it, the rest of the system almost certainly does too. A full TR19® clean deals with the canopy, ductwork and fan together and you get a TR19 certificate and photo report afterwards.
A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, which means the fan is seen regularly and wear is caught earlier.

What else we do in Russell Hill
Part by part
Belt-driven fans
In a belt-driven fan, the motor drives the impeller by belt. Belts wear, stretch and slip, so we check the pulleys and bearings as well.
Fan controls
Every fan has controls, from a speed controller to an isolator. A control fault can leave the fan dead or stuck at one speed.
How we price extract fan repair
Every site gets its own quote. This is what makes a difference:
- Whether it’s a one-off visit or part of a schedule
- Site rules, permits and inductions
- The scale of the work
- Whether several sites go on one quote
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.
What to send for a quote
You don’t need the technical terms. It helps if you can send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide pictures of the system and the area around it
- The site address and the type of premises
- When the site is open and when it’s quiet
To help us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711, or send details by email.
What we do, step by step
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and hand over the paperwork. On site, the work takes anything from an hour or two to a full visit, depending on the fault. Most London sites can’t stop for the day, so work in Russell Hill is normally done overnight, early in the morning or at weekends.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- 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 hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
- We fix or replace the fan, then test it running before we leave.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Move anything stored near the system
- Agree a time when the area can be out of use
Get a fixed quote
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. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building to keep disruption down.
