Extract fan cleaning in Stonebridge Park
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. Typical jobs include grease escaping from the fan outlet and a fan that hums, whines or rumbles, across centrifugal fans, discharge points and fan housings.
In London, few kitchens can spare a day to close, so extract cleaning in Stonebridge Park is normally done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Aftercare tips
After the visit, a few habits help the work last:
- Check the report shows the fan was cleaned
- Listen for new noises or vibration from the fan
- Note any drop in extraction at the canopy
- Never cook with a filter missing
File the photo report with your other extract records. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
Do not run the kitchen with the extract off. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
Extract fan cleaning around Stonebridge Park
Food Standards Agency data counts about 312 cafés, restaurants and staff canteens and about 295 takeaways in Stonebridge Park and the streets around it, up to about 1.5 miles out. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Food hygiene inspections in Stonebridge Park are the job of Brent council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. Stonebridge Park sits within the area of London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.

The process
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 photos. Most of the time goes on the work itself, and that takes a few hours where there are several fans or heavy deposits. Getting kit into a London building takes planning, so let us know where we can load and park in Stonebridge Park.
- The fan is found and its type, access and isolation checked.
- It’s isolated so it can’t run while we work.
- Grease is scraped off the impeller blades and casing.
- Blades, housing and surrounds are degreased with care around the electrics.
- It’s closed up, run, checked and photographed for the report.
Preparing for the visit
- Mention any parking or loading restrictions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know when the site is closed or quiet
Get a fixed 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.
Advice
Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
How the job changes from site to site
Wall fans
Grease can mark the outside wall around the fan. We clean the fan and check the outlet.
Roof-mounted fans
Many kitchen extracts end at a fan on the roof. We clean them where they can be safely reached, and anything we can’t reach is recorded.

Why it’s worth doing now in Stonebridge Park
Grease on a roof fan can also escape outside. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

Questions from Stonebridge Park
Can you clean school kitchen extracts in Stonebridge Park during the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 41 schools and colleges with food registrations within roughly a mile and a half of Stonebridge Park. You can give us a ring on 0345 646 2711 or use the quote form with the dates the site is empty.
How do you handle parking and loading in Stonebridge Park?
Tell us where a van can stop near your site in Stonebridge Park, and about any building rules on loading. Night visits tend to make loading easier on London streets.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Do we need to close while you work?
Not normally. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
What should I send you?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
What does extract fan cleaning cost?
It depends on the site, so we quote each one individually. To get one, give us a ring on 0345 646 2711 or drop us a line and tell us about the site and its opening hours.
Why is my extract fan noisy?
An unbalanced impeller, usually from uneven grease, is a common cause. We clean the fan and tell you if anything else, like worn bearings, is to blame.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
When to call us in Stonebridge Park
A fan on a roof or hidden in a ceiling void is easy to forget. If it wasn’t included in past cleans, it may hold years of grease, and the report will show it.
Common reasons sites call us are:
- A heavily greased fan housing
- A fan left out of previous cleans
- Grease around the motor and its mounts
- Hot, greasy smells near the fan
If you run catering at a healthcare site, such as a hospital like Neasden Hospital about 0.6 miles north-east, the extract may need cleaning more often than a part-time kitchen.
