What extract fan repair looks like in Cranham
Look up Cranham on the FSA’s food hygiene register and you’ll find about 82 restaurants, cafés and works canteens and about 22 takeaways within 1.5 miles or so of the middle of Cranham. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Kitchens in Cranham get their food hygiene inspections from Havering 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. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement.
If you run a school kitchen, at a school such as Hall Mead School or nearby, a fan that’s getting noisy is best repaired in the holidays before it fails in term. Occasional-use kitchens, such as a hall kitchen near St Luke's Cranham or elsewhere in Cranham, are where a stiff or seized fan can turn up.

About our extract fan repair in Cranham
Diagnosis comes before parts. The motor, drive, impeller, bearings and mounts are all checked and the speed control too. Then you’re given a fixed quote for the repair or the replacement. If you are dealing with a fan that whines, hums or grinds and an old fan that needs replacing, we can help.
Replacing a fan in a London building often means working at height or in a tight plant space, and in Cranham, parking and lifting are part of that. Repairs can be done out of hours so the kitchen keeps trading.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Questions from Cranham
Is parking a problem for work in Cranham?
A loading bay, a visitor permit or off-street space near the site in Cranham makes the visit easier to plan. Working overnight, as we often do in London, normally makes it simpler.
Do you work overnight in Cranham?
Yes, out-of-hours work is a big part of what we do. That way a site in Cranham does not have to lose a day’s trading. Just call 0345 646 2711 or email us with your opening times and we will plan around them.
Will you tell us when the next visit is due?
Yes. The recommended date is 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.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
Do you replace extract fans as well as repair them?
We can. We fit replacement fans as well as repairing old ones, and we’ll explain the options.
Is TR19 a legal requirement?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and without records, many insurers may refuse or reduce a claim.
How long will the fan be out of action?
Most fan jobs take part of a day for most faults, with a return visit if parts have to be ordered, including testing. We plan the work around your service where possible.
How we price extract fan repair
Before we fix a price, we need to know a few things. We look at:
- The condition of the system
- The scale of the work
- The number of sites or systems
- How easy every part is to reach
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before any work starts.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Your last certificate, test record or report
- Any access panels or hatches you can see
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
For extract fan repair in Cranham, call us on 0345 646 2711, or email photos. Let us know the site type and the opening hours, and send photos or your last report if you can. We typically send a fixed quote within one working day.
How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a few hours on site, depending on the fault and the access to the fan. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Cranham.
- We ask what the fan is doing, from noise and vibration to a full stop.
- With the fan safely isolated, we open it up for a proper look.
- We check the motor, bearings, drive, impeller and mountings.
- You get our diagnosis and a fixed quote to repair or replace.
- Once the work is done, we run the fan and check it’s steady and quiet.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system
- Let us know when the site is closed or quiet
Getting a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Avoid lowering the speed to quieten a fault
- Report new noises from the fan early
- Keep the area around the fan controls clear
- Do not cook with gaps in the filter bank
If parts have to be ordered, we tell you how the kitchen can carry on in the meantime. The fan is completed on a return visit outside your busiest hours.
Regular TR19 cleaning includes the extract fan. Keeping grease off the impeller is one of the simplest ways to protect it, so planned cleaning helps the fan last.
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. In Cranham, a planned overnight visit is much easier than closing unexpectedly.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.
Why choose Duct Doctor in Cranham
- Fixed quotes from a survey or photos
- Work around your opening hours, with 24/7 emergency cover

Do you need extract fan repair in Cranham?
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.
Common reasons sites call us are:
- A fan that whines, hums or grinds
- A fan that will not start at all
- A knocking noise from the extract fan
- A failed fan that needs a replacement
For kitchens close to Upminster station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7.
Questions to ask before you book
- How areas they can’t reach will be recorded
- Whether the price is fixed
- Whether they’re fully insured
- Whether the work can be done while the site is closed
What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
