How we handle extract fan repair in Knox Bridge

Everything a kitchen extract does depends on the fan. When it starts to rattle, hum or slow down, the cooking area soon fills with heat and fumes. Our engineers track down the fault and fix it, by repairing the fan or replacing it. Typical jobs include weak extraction and a smoky kitchen and a knocking noise from the extract fan, across belts and pulleys, roof and wall fans and fan motors.

A callout to a small place like Knox Bridge goes better when we know what we’re looking at: pictures of the fan, its rating plate and how to reach it all help.

We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Knox Bridge questions

Who do I call if an extract fan fails in Knox Bridge?

Our emergency line runs 24/7, and Knox Bridge is within the area we cover. Ring 0345 646 2711 at any hour and describe the fault. A photo of the fan’s rating plate helps.

Do you cover smaller places like Knox Bridge?

Yes. Villages and rural sites across the South East are part of our work, Knox Bridge included. Photos of the system and directions to the site help us plan the visit.

What is TR19?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.

Will we have to shut during the visit?

Not normally. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.

Will you tell us when the next visit is due?

Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.

How much does an extract fan repair cost?

The price depends on the diagnosis. Once we have looked at it, you get a fixed quote for the repair or the replacement.

Do you replace extract fans as well as repair them?

Yes, when repair does not make sense. The replacement has to suit the ductwork and the cooking so we confirm that first.

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.

Staff cleaning versus specialist work

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

The process

The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, which takes a few hours on site, depending on the fault and the access to the fan. Somewhere like Knox Bridge, lanes, gates and parking are worth mentioning in advance.

  1. We ask what the fan is doing, from noise and vibration to a full stop.
  2. The fan is isolated and opened up so we can see inside.
  3. Each part is checked in turn: motor, bearings, drive, impeller and fixings.
  4. We explain the fault and give you a fixed price for the fix.
  5. We fix or replace the fan, then test it running before we leave.

Preparing for the visit

  • Dig out any earlier paperwork for the system
  • Let us know when the site is closed or quiet
  • Plan for cooking equipment or plant to be off before we arrive

Ask for a quote

Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, call 0345 646 2711, or send details by email.

Advice

When to call us in Knox Bridge

Over the years, mountings loosen and rubber mounts break down. The fan’s movement then travels into the ductwork and structure and that’s a common source of rattles.

Keep an eye out for these warning signs:

  • An old fan that needs replacing
  • A whining or grinding extract motor
  • A belt-driven fan that squeals
  • A fan shaking on its mountings

For kitchens in and around Knox Bridge, our emergency line runs 24/7.

What your quote should include

  • Whether the price is fixed
  • When they can work, and whether that is outside your opening hours
  • When the next visit should be, and why
  • Whether inaccessible sections are listed on the report

Our hiring checklist

Managing agents and facilities teams in Knox Bridge

Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.

Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.

Keeping the system healthy

Looking after the system between visits is straightforward, and it helps at the next visit:

  • Tell us about a new rattle or whine straight away
  • Make sure the fan is cleaned with the rest of the system
  • Keep a record of any trips or stoppages
  • Keep the emergency number where staff can see it

Your kitchen can get back to normal as soon as the fan is running. We leave the area tidy and explain anything you need to know.

A scheduled maintenance plan keeps the whole system on a regular cycle, so the fan is looked at as part of each visit and problems are spotted sooner.

When something else is needed

In fairness, some problems need a different fix:

  • Odour complaints that need filtration rather than a fan repair
  • A system that needs redesigning rather than repairing
  • Grease throughout the ductwork, which needs a full TR19 clean

If you are not sure, just phone us on 0345 646 2711 or use the quote form and we’ll give you a straight answer.

Where we work

  • Fan motors
  • Bearings
  • Belts and pulleys
  • Roof and wall fans
  • Fan housings
  • Kitchen extract fans

Part by part

Impellers and housings

The impeller does the work of moving air through the system. Grease on it throws it out of balance and cause vibration.

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 itself may be failing.
