Managing agents and facilities teams in Bexley
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
Extract fan repair for kitchens and businesses in Bexley
Before anything is ordered, we diagnose. We look at the motor, the belts or direct drive, the impeller and the mountings, along with the fan’s controls. Then you’re given a fixed quote for the repair or the replacement. The work covers roof and wall fans, kitchen extract fans and belts and pulleys, and the jobs we see most are a humming noise from the fan motor and an overheating extract motor.
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.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

In-house cleaning or a specialist?
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.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
How the job changes from site to site
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.
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 talk you through it.
Between visits
Aftercare is simple, and it helps at the next visit:
- Get a noisy fan checked rather than slowed down
- Report new noises from the fan early
- Don’t cook with gaps in the filter bank
- Make sure the isolator and controls are easy to reach
Once the fan is running smoothly, keep the filters clean. Less grease on the impeller means less wear and fewer faults.
The fan is part of every full TR19 clean. Keeping grease off the impeller is one of the simplest ways to protect it, so planned cleaning helps the fan last.
When to call us in Bexley
Fan bearings don’t last for ever, especially in a hot, greasy airstream. Worn bearings whine, rumble or grind and a seized bearing stops the fan.
It’s time to book a visit if you see:
- An extract that vibrates through the ductwork
- A fan that won’t start at all
- A belt-driven fan that squeals
- An old fan that needs replacing
If you run a school kitchen, at a school such as Old Bexley Church of England School or nearby, a fan that’s getting noisy is best repaired in the holidays before it fails in term.

Bexley: your questions answered
Can parking be tricky for a job in Bexley?
Tell us where a van can stop near your site in Bexley, and about any building rules on loading. Much of our London work is done overnight, which helps.
Can you come to Bexley after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
Does a fan repair include cleaning the ductwork?
Often it makes sense to do both. A full clean takes in the whole extract, including the fan, with a certificate and photo report.
How much does an extract fan repair cost?
We cannot price it without knowing the fault. Once we’ve looked at it, you get a fixed quote for the repair or the replacement.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Can you repair a fan rather than replace it?
It depends on the fault. After diagnosing, we explain whether it can be repaired, then give you a fixed quote.
Which sectors do you work in?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.

What else we do in Bexley
What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes an hour or two to diagnose, then longer if parts or a new fan are needed. Getting kit into a London building takes planning, so let us know where we can load and park in Bexley.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- With the fan safely isolated, we open it up for a proper look.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- We explain the fault and give you a fixed price for the fix.
- We fix or replace the fan, then test it running before we leave.
Before we arrive
- Clear loose items from the work area
- Have your last certificate or report to hand
- Name a contact who can let us in at the agreed time
Get a fixed quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before any work starts.

When something else is needed
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Problems with the electrical supply to the fan (an electrician’s job)
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- Odour complaints that need filtration rather than a fan repair
If you’re not sure, just give us a ring on 0345 646 2711, or email photos and we will give you a straight answer before you book.

Extract fan repair around Bexley
There are about 146 cafés, restaurants and staff canteens and about 48 takeaways within 1.5 miles or so of the middle of Bexley, according to the Food Standards Agency’s register. Those that cook under a canopy rely on a fan that runs every hour they’re open. In London, a fan on a roof or in a basement can take planning to reach, with parking and loading to arrange. In Bexley, food businesses are inspected by environmental health officers from Bexley 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.
If you look after a church or hall kitchen near Parish Church of St John the Evangelist, or anywhere in Bexley, test the extract fan before a big event rather than on the day. For a takeaway near Bexley station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.
