Extract fan repair for sites in Avery Hill

What your team can do, and what needs us

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.

Extract fan repair in Avery Hill, done properly

Grease and fans don’t mix. A coated impeller spins unevenly, which shakes the bearings and mountings. That’s why we check the grease whenever we work on a fan, and a full TR19® clean can be booked alongside. If you are dealing with a motor that trips out or overheats and an extract fan that rattles or knocks, we can help.

London extract fans often sit on rooftops, exposed to the weather as well as the grease, and in time, bearings, belts and motors fail. Noise and vibration are worth reporting before the fan stops.

Good records are part of the job. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

When a fan fails in Avery Hill

The FSA’s food hygiene register shows about 152 restaurants, cafés and works canteens and about 96 sandwich bars and takeaways within roughly a mile and a half of the centre of Avery Hill. For any of them with a canopy, the extract fan is what keeps the kitchen usable. It’s Greenwich council that sends environmental health officers to food businesses in Avery Hill. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. That is one more reason not to keep cooking with a broken fan. London extract fans are often at the end of long duct runs, on roofs or in basements.

If you run a kitchen close to Falconwood station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush. If you look after a church or hall kitchen near Church of Holy Trinity, or anywhere in Avery Hill, test the extract fan before a big event rather than on the day. School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Stationers' Crown Woods Academy, fix a failing fan before term starts.

For landlords and multi-site operators

Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.

We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

The process

Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the extract fan repair, clear away and hand over the paperwork. The visit itself takes a few hours on site, depending on the fault and the access to the fan. Getting kit into a London building takes planning, so let us know where we can load and park in Avery Hill.

  1. You describe the fault and we arrange a visit.
  2. On site, the fan is safely isolated.
  3. We diagnose the fault, checking the controls as well as the fan.
  4. You get a fixed price for putting it right.
  5. We fix the fault and run the fan to check it.

How to prepare

  • Allow time for equipment near the work to be turned off and cool down
  • Clear the space around the work
  • Tell us where we can park and unload

Get a fixed quote

To help us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711 or use the quote form.

When it’s something else

Extract fan repair cannot fix everything, and we will tell you before we start. It won’t put right:

  • Grease throughout the ductwork, which needs a full TR19 clean
  • Cooking smells reaching neighbours, which may need odour control
  • A system that needs redesigning rather than repairing

Not sure which it is? You can call 0345 646 2711 or email us and we will tell you honestly before you book.

Where we work

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

Leave it or put it right?

Left alone, vibration spreads its damage. Fixings work loose and joints in the ductwork can be strained and the eventual repair is larger. A busy site in Avery Hill builds up dirt and wear quickly, so putting it off makes the eventual job larger.

What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before work begins.

Why Avery Hill businesses choose us

  • Fully insured
  • Work around your opening hours, with 24/7 emergency cover
  • Every job surveyed first
  • A fixed price before any work starts

Common questions in Avery Hill

Who inspects food businesses in Avery Hill?

That’s Greenwich council, whose environmental health officers carry out food hygiene inspections in Avery Hill. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.

Is there an emergency callout for extract fans in Avery Hill?

Avery Hill is covered, and our emergency callout runs 24/7. Call 0345 646 2711 and tell us what the fan is doing, or not doing. Tell us where the fan is and how to reach it.

How far ahead should we book?

The more notice, the better, particularly for night and weekend visits. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.

Does a faulty extract fan always need replacing?

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

What happens if you can’t reach some of it?

We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.

Why is our extract fan so noisy?

An unbalanced, greasy impeller vibrates, which is a common cause of noise. Bearings, belts and mountings can also be to blame.

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 fixed quote is built on it.

Do I get a report after the visit?

Yes, on every job. The report is dated and includes pictures, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.

What affects the quote in Avery Hill

There’s no set price list, because no two systems are the same. What we look at:

  • The size of the system
  • A single visit or a regular plan
  • Site rules, permits and inductions
  • The number of sites or systems

We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or email us, and we’ll explain what it covers.

Asking for a quote

We can often survey from photos. The most useful are:

  • The postcode and the type of business
  • 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
  • Problems your staff have spotted

If you need extract fan repair in Avery Hill, call 0345 646 2711 or drop us a line. Let us know the site type and the opening hours, and send photos or your last report if you can. We normally send a fixed quote within one working day.

How the job changes from site to site

Roof and wall-mounted fans

Many kitchen extract fans sit on a roof or an outside wall. How easy the fan is to reach shapes the job and we plan around it.

Belt-driven fans

Belt drives have more moving parts than direct-drive fans. More parts to inspect, but many faults are straightforward to fix.
