Extract fan repair in Patchetts Green

Extract fan repair for kitchens and businesses in Patchetts Green

Before anything is ordered, we diagnose. We look at the motor, the belts or direct drive, the impeller and the mountings and the speed control too. After that, you get a fixed price for what’s needed. We are often asked to deal with an overheating extract motor and vibration spreading from the fan into the ducts, across bearings, fan motors and roof and wall fans.

Rural kitchens often have fans mounted on outside walls or roofs, exposed to the weather. Weather and grease together wear out motors and bearings.

Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Do you need extract fan repair in Patchetts Green?

Some grease always slips past the filters and reaches the fan. Deposits gather on the blades, never quite evenly, so the fan runs out of balance and the noise follows.

These are the problems we see most often:

  • Vibration spreading from the fan into the ducts
  • A failed fan that needs a replacement
  • A fan that whines, hums or grinds
  • A knocking noise from the extract fan

Occasional-use kitchens, such as a hall kitchen near Church of St John the Baptist or elsewhere in Patchetts Green, are where a stiff or seized fan can turn up.

Patchetts Green questions

Who do I call if an extract fan fails in Patchetts Green?

Extract fan emergencies in Patchetts Green are covered around the clock. Ring 0345 646 2711 at any hour and describe the fault. Details of the make and model help us plan the repair.

Can you get to a site in Patchetts Green?

Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.

Do you work with multi-site operators?

Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.

Does the report say when we need you again?

Yes. We put a recommended next date on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, and fire dampers need testing at least once a year.

What makes a kitchen extract fan rattle or whine?

Noise typically comes from grease build-up, bearings, belts or loose fixings. Each sounds a little different and we find the exact cause on site.

How much notice do you need?

The more notice, the better, especially for out-of-hours work. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.

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.

Does a fan repair include cleaning the ductwork?

The ductwork is a separate job. We’ll tell you what we see, so you can decide whether to book a TR19 clean.

What affects the cost of extract fan repair

The diagnosis comes before the price. The main factors are:

  • The number of sites or systems
  • Where the site is and how we reach it
  • Site rules, permits and inductions
  • The size of the system

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

What we need to know

To help us quote quickly, send us:

  • Your opening hours and when the area is out of use
  • A few general shots of the system
  • Any access panels or hatches you can see
  • The postcode and the type of business

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

What we do, step by step

There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes part of a day for most faults, with a return visit if parts have to be ordered. A few photos of the system help us make the most of a visit to a place like Patchetts Green.

  1. A visit is booked, in the evening or overnight if that suits.
  2. We isolate the extract and open the fan housing.
  3. We inspect every moving part and the fixings.
  4. We explain the options and quote a fixed price.
  5. The fan is repaired or replaced, then checked running.

Preparing for the visit

  • Plan for cooking equipment or plant to be off before we arrive
  • Tell us about site rules, permits or sign-in
  • Make sure someone can let us in and lock up afterwards

How to get a 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. Add the site type and your opening hours, and many jobs can be priced from that alone.

Why act early in Patchetts Green

A noisy fan rarely fixes itself. Bearings that are left to wear can fail suddenly, and that often happens mid-service. A repair booked now is simpler than an emergency later. Our emergency line runs 24/7, but a planned visit to Patchetts Green is calmer for everyone.

One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.

Why us?

  • Ventilation hygiene specialists since 2009
  • Photo reports with every job
  • CHAS, SafeContractor and ISO 9001
  • A single point of contact for sites across the South East and London

What the work involves, part by part

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.

Direct-drive fans

Direct-drive fans are compact and common in kitchen extracts. If the motor has gone, a replacement unit is often the sensible option, and we’ll explain why.

Multi-site and managed buildings

Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.

What a clean won’t put right

A few issues sit outside what this work can do:

  • An extract system that was undersized from the start
  • Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
  • Smells from the discharge that need odour control equipment

If in doubt, phone us on 0345 646 2711 or drop us a line and we’ll say what we think.
