Extract fan repair in Lower Morden

Extract fan repair for kitchens and businesses in Lower Morden

Every fan job begins with finding the fault. A noisy fan might need cleaning, new bearings or a new belt; a dead fan can point to the motor or its controls. We explain the problem, and what it will take, before we start. The work covers roof and wall fans, fan housings and fan motors, and common reasons people get in touch are a whining or grinding extract motor and an extract fan that rattles or knocks.

In London, getting a new fan to the roof or plant room can take planning, and in Lower Morden, parking and lifting are part of that. Repairs can be done out of hours so the kitchen keeps trading.

Good records are part of the job. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

When it’s something else

Not every problem is solved by extract fan repair, and we will tell you before any work starts. It will not put right:

  • Smells from the discharge that need odour control equipment
  • Wiring and supply faults beyond the fan itself
  • A system that needs redesigning rather than repairing

Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we will tell you honestly before you book.

What happens on the day

Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes part of a day for most faults, with a return visit if parts have to be ordered. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Lower Morden.

  1. First, you tell us the symptoms: noise, shaking, weak extraction or no power.
  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. You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
  5. The repair or replacement is carried out and the fan is run and checked.

Advice

How we price extract fan repair

Some jobs are bigger than they look, and some smaller. The main factors:

  • Site requirements such as sign-in and permits
  • When the work can happen, such as evenings, overnight or weekends
  • Travel, parking and unloading
  • Whether several sites go on one quote

No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

What we need to know

We can often survey from photos. Try to include:

  • Your opening hours and when the area is out of use
  • Any symptoms, from odd noises to smells or leaks
  • Close-ups of filters, grilles, hatches or access panels
  • Where the plant sits or the system leaves the building, such as a roof or outside wall

For extract fan repair in Lower Morden, give us a ring on 0345 646 2711 or email us. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. A fixed quote usually follows within one working day.

Leave it or put it right?

An overloaded motor is under constant strain. That shortens its life and a burnt-out motor is a bigger job than a worn belt. Catching it early keeps the repair small. A booked night’s work in Lower Morden costs you no trading time; an unplanned closure does.

We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711, or send details by email, and we’ll explain what it covers.

Different parts, different methods

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.

Belt-driven fans

Squealing at start-up often points to a belt. Belts are checked for wear, tension and alignment and replaced if they’re worn.

What your team can do, and what needs us

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

Signs you need extract fan repair in Lower Morden

Blocked filters and greasy ducts make the fan work harder. An overworked motor overheats and may cut out or fail.

The symptoms we’re asked about most include:

  • A belt-driven fan that squeals
  • A knocking noise from the extract fan
  • An extract that vibrates through the ductwork
  • An overheating extract motor

For school kitchens, at schools like Aragon Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time.

What your quote should include

  • What records you’ll receive afterwards
  • How they set the interval to the next visit
  • Whether a survey comes first
  • Which accreditations they hold, and whether you can check them

Our hiring checklist

What extract fan repair looks like in Lower Morden

The FSA’s food hygiene register shows about 150 restaurants, cafés and canteens and about 73 takeaways and sandwich shops within about 1.5 miles of central Lower Morden. Wherever they cook under a canopy, a failed extract fan stops the kitchen. In Lower Morden, food businesses are inspected by environmental health officers from Merton council. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. A kitchen without a working fan has a problem to fix quickly. We ask about access first for a London fan job, because roofs and basements need planning.

If you run a café or takeaway near St Helier station, a failed fan in the middle of service is exactly what our 24/7 emergency line is for. Hall kitchens near St Martin's, or anywhere around Lower Morden, often use their fans only now and then, and an idle fan can stick.

FAQs for Lower Morden

Do you cover Lower Morden for emergency fan repairs?

We run a 24/7 emergency line for failed extract fans, and Lower Morden is part of our area. The number to ring is 0345 646 2711. Details of the make and model help us plan the repair.

Which environmental health team covers Lower Morden?

That’s Merton council, whose environmental health officers carry out food hygiene inspections in Lower Morden. If the extract fan has failed, it’s worth having the repair booked, and the details to hand, before an officer visits.

What about areas you cannot get to?

The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.

Will you fit a new fan if ours can’t be repaired?

Yes. If repair is not sensible, we replace the fan. The replacement has to suit the ductwork and the cooking so we confirm that first.

Will I get paperwork for my records?

Yes. You get a written report with photos after every visit, covering the work, any areas we couldn’t access and the recommended next date. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.

Are you accredited?

Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Who has the legal duty for fire safety?

In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.

Can you repair a fan rather than replace it?

Often, yes. Many faults are fixed by cleaning the impeller or renewing worn parts and we only recommend replacement when repair does not make sense.
