How we handle extract fan cleaning in Grubb Street
Any fan serving a kitchen in Grubb Street is cleaned the same careful way as anywhere else: we isolate it, open the housing, scrape the impeller and degrease the lot. The result is photographed for your records. We are often asked to deal with hot, greasy smells near the fan and a fan that hums, whines or rumbles, across fan housings, discharge points and roof-mounted fans.
In a small place like Grubb Street, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

The process
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, and that takes a couple of hours per fan, depending on its size and the build-up. Visits to a village like Grubb Street are booked in advance, at a time that suits whoever runs the site.
- The fan is found and its type, access and isolation checked.
- We isolate the power before opening the housing.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- We reassemble, run and photograph the fan.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
How to get a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Then give us a ring on 0345 646 2711 or send us an email.
Advice
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
How we price extract fan cleaning
We do not publish a price list, because no two systems are the same. What we look at:
- What state the system is in
- Parking and loading at the site
- One-off work versus a regular cycle
- The scale of the work
A single site or a whole portfolio, 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.
Asking for a quote
To speed up the quote, send us:
- When the site is open and when it’s quiet
- Wide pictures of the system and the area around it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Where the site is and what kind of site it is
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Signs you need extract fan cleaning in Grubb Street
Poor filters mean a greasier fan. When filters don’t seal, grease goes straight through to the fan, so the fan takes far more than it should.
The symptoms we’re asked about most include:
- A heavily greased fan housing
- A fan shaking on its mounts
- A noisy fan that has got louder over time
- A fan left out of previous cleans
If you run catering at a healthcare site, such as a hospital like Darent Valley Hospital about 2.3 miles north-west, the extract may need cleaning more often than a part-time kitchen.
What your quote should include
- Whether the whole system is included, or only the parts that are easy to reach
- When the next visit should be, and why
- Whether the figure could change on the day
- How VAT is shown on the quote
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, and that’s where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Your questions about extract fan cleaning in Grubb Street
Can school kitchens in Grubb Street be cleaned in the holidays?
Yes, and it’s the easiest time to do it. Around Grubb Street, the Food Standards Agency lists about 8 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Can you get to a site in Grubb Street?
Yes. Villages and rural sites across the South East are part of our work, Grubb Street included. A survey first, from photos or a visit, means we arrive with the right kit.
Do you repair extract fans as well as clean them?
Fan repair and replacement is part of what we do. If cleaning shows a worn motor, bearings or impeller, we will tell you and quote for the repair.
Is there a survey before the work?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
What should I send you?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Call us any time and explain what’s happened.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.

Kitchen extracts in Grubb Street
There are about 9 cafés, restaurants and staff canteens and about 7 takeaways across Grubb Street and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. The fan at the end of each of those extracts collects grease that slows it and wears the motor. Kent Fire and Rescue Service covers Grubb Street. 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. It’s Dartford council that sends environmental health officers to food businesses in Grubb Street. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
Where a hall near Church of Saint Mary Magdalene, or anywhere in Grubb Street, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Bursars and site managers at schools such as Greenlands Primary School tend to book extract cleaning for when the kitchen is empty.

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Keep the grease filters clean and in place
- Tell us if the extract feels weaker
- Watch for grease marks around the outlet
- Leave a clear route to the fan
The area around the fan is left clean, with waste grease removed. On a roof or outside wall, we leave the surrounding area tidy.
Do not run the kitchen with the extract off. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.
