Extract fan repair in Petts Wood

How the job changes from site to site

Fan controls

We check the controls as part of every diagnosis, because a fan that will not start isn’t always a failed motor.

Motors and bearings

Motors and bearings take the most strain in a kitchen extract fan. Hot, greasy air and long days wear them down.

Extract fan repair in Petts Wood, done properly

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. We find out why and put it right, by repairing the fan or replacing it. The work covers fan motors, bearings and roof and wall fans, and common reasons people get in touch are a belt-driven fan that squeals and an old fan that needs replacing.

London extract fans often sit on rooftops, exposed to the weather as well as the grease, and in time, bearings, belts and motors fail. A fan that is noisy or vibrating is giving a warning.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How the visit works

We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes a few hours for most repairs, longer for a full fan replacement. In Petts Wood, as across London, we usually work overnight or at weekends and hand the site back ready to open.

  1. You describe the fault and we arrange a visit.
  2. We isolate the fan before touching it.
  3. We diagnose the fault, checking the controls as well as the fan.
  4. A fixed quote for the repair or replacement follows.
  5. We fix the fault and run the fan to check it.

Getting ready for the visit

  • Mention any locked doors, roof access or ceiling voids
  • Tell us about site rules, permits or sign-in
  • Plan for cooking equipment or plant to be off before we arrive

Getting a quote

For a fixed quote, give us a ring on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You’ll typically have a quote within one working day.

Petts Wood questions

Who would carry out a food hygiene inspection at a kitchen in Petts Wood?

That’s Bromley council, whose environmental health officers carry out food hygiene inspections in Petts Wood. 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 out to a failed extract fan in Petts Wood out of hours?

We run a 24/7 emergency line for failed extract fans, and Petts Wood is part of our area. The number to ring is 0345 646 2711. A photo of the fan’s rating plate helps.

Are you fully insured?

Yes. Full insurance covers our work, and we have been trading since 2009.

How long does an extract fan repair take?

Typically, a fan repair takes a few hours for most repairs, longer for a full fan replacement. If parts have to be ordered, we will tell you how long that is likely to be.

Who has the legal duty for fire safety?

Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.

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 it takes a risk-based approach.

Is TR19 a legal requirement?

No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005 in England and Wales.

Do you survey before quoting?

Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.

Do you need extract fan repair in Petts Wood?

Not every problem is mechanical. A failed speed controller or a wiring fault can stop a fan so we check the controls before blaming the motor.

It’s time to book a visit if you see:

  • A fan that will not start at all
  • A squealing belt on start-up
  • Weak extraction and a smoky kitchen
  • An extract fan that rattles or knocks

If you run a kitchen close to Petts Wood station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush.

Questions to ask before you book

  • Whether the price is fixed
  • Whether VAT is included
  • Exactly which parts of the system are covered
  • Proof of accreditation you can verify

What affects the quote in Petts Wood

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • When the work can happen, such as evenings, overnight or weekends
  • Parking and loading at the site
  • The scale of the work
  • Site requirements such as sign-in and permits

When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.

What to send for a quote

The more you tell us, the more accurate the quote. When you get in touch, it helps to send:

  • Detail shots of panels, filters and grilles
  • Any previous report or certificate
  • The roof, plant room or outside wall the system runs to
  • Any symptoms, from odd noises to smells or leaks

To help us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, ring 0345 646 2711 or send us an email.

Extract fan repair around Petts Wood

Food Standards Agency records list about 103 restaurants, cafés and works canteens and about 57 takeaways and sandwich shops within 1.5 miles or so of the middle of Petts Wood. For any of them with a canopy, the extract fan is what keeps the kitchen usable. Food hygiene inspections in Petts Wood are the job of Bromley council’s environmental health team. Food hygiene rules expect food premises to have suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month. London extract fans are often at the end of long duct runs, on roofs or in basements.

A fan that rarely runs, like one in a hall kitchen near St Francis Church or elsewhere in Petts Wood, can seize between uses. Holidays are the time to replace a tired kitchen fan at schools such as Crofton Junior School, rather than mid-term.

What a clean will not put right

Before booking, it helps to know what’s not included:

  • Ductwork designed too small for the kitchen’s cooking
  • Gas interlock faults that a Gas Safe registered engineer must deal with
  • A greasy canopy and duct that a fan repair won’t touch

If you’re not sure, just phone us on 0345 646 2711, or send details by email and we will give you a straight answer before booking.

Parts of the system we cover

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

What staff can safely do

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.

For landlords and multi-site operators

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.

Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
