How the job changes from site to site
Restaurant and pub kitchens
Grills, fryers and woks send a lot of fat into the extract, and measured readings show whether the minimum interval is enough.
Grease filters
We clean the grease filters as part of the job, and put back so they seat correctly. We will tell you if any need replacing.
Kitchen extract cleaning in Wealdstone
Duct Doctor has been cleaning kitchen extract systems since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001 and are fully insured. Common call-outs are for proof of cleaning requested by an insurer and fat running down the canopy edge, across plenums and filters, horizontal duct runs and vertical risers. Searching for commercial kitchen extraction cleaning in Wealdstone? Duct Doctor has covered London and the South East since 2009, as a BESCA Vent Hygiene Elite member.
Before we clean, we look at where the grease is: grease readings at set points tell us where the heaviest deposits are, and readings afterwards go into your report.
In London, few kitchens can spare a day to close, so extract cleaning in Wealdstone is normally done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

When to call us in Wealdstone
Grease in the extract matters because it burns. A flare-up on the range can be drawn up into the canopy and duct, and once grease in the duct catches, fire can spread through the building’s ductwork. That is why controlling extract grease belongs in the fire risk assessment.
It’s time to book a visit if you see:
- An extract that has never been cleaned to TR19
- A TR19 certificate needed for the insurer
- Fat running down the canopy edge
- A smoky, hot kitchen with weak extraction
A kitchen near Harrow & Wealdstone station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
Questions to ask before booking
- Whether the price is fixed
- Which accreditations they hold, and whether you can check them
- Exactly which parts of the system are covered
- Whether they’re fully insured
Kitchen extract cleaning around Wealdstone
Food Standards Agency data counts about 243 cafés, restaurants and staff canteens and about 91 takeaways and sandwich shops in Wealdstone and the streets around it, up to about 1.5 miles out. Wherever food is cooked under a canopy, the extract above it gathers grease and needs cleaning on a schedule. London jobs normally start after the last service, with loading and roof access agreed with the building first. In Wealdstone, food businesses are inspected by environmental health officers from Harrow council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Northwick Park Hospital is the nearest hospital to Wealdstone, about 1.3 miles south. Bursars and site managers at schools such as Marlborough Primary School tend to book extract cleaning for when the kitchen is empty.

How we price kitchen extract cleaning
There’s no set price list, because no two systems are the same. The quote depends on:
- Any permits to work or inductions
- The condition we find in the survey
- The number of sites or systems
- Travel, parking and unloading
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
When you call or email, these details help:
- Your opening hours and when the area is out of use
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.

In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is 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. Cleaning inside ducts and units is specialist work.
How it works
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from a few hours to a full night, depending on the size of the system. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Wealdstone.
- We survey the system first, from your photos and details or on a site visit.
- Grease readings are taken at set points and you get a fixed quote.
- On the day, cooking equipment is switched off and left to cool, and everything nearby is sheeted.
- The whole route is cleaned, from the canopy through the ductwork to the fan and the discharge.
- Finally the system is re-tested and photographed, and the certificate and report follow.
How to prepare
- Name a contact who can let us in at the agreed time
- Mention any parking or loading restrictions
- Clear loose items from the work area
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

What happens if it’s left?
Grease that is left only gets thicker. BESA guidance says the mean should not go above 200 microns between cleans, and anywhere reaching 500 microns or more needs a spot clean right away. The longer it’s left, the bigger the job becomes. A building in Wealdstone may have flats or offices above and alongside, and a fault in the system can affect them too.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, call us on 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.

For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
Your questions about kitchen extract cleaning in Wealdstone
Can parking be tricky for a job in Wealdstone?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
Do you work at weekends in Wealdstone?
Yes, nights and weekends are routine for us. That way a site in Wealdstone does not have to lose a day’s trading. Let us know the hours you are closed and we will book within them.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Are you accredited for kitchen extract cleaning?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Do I have to clean my extract to TR19 by law?
The legal duty sits in the Fire Safety Order 2005 rather than in TR19 itself. In practice, TR19 is how kitchens show they’re managing grease, and an insurer may refuse or reduce a claim without it.
Will my insurer ask for a TR19 certificate?
Because a dirty extract can spread a fire through a building. Many policies say the extract must be cleaned to TR19, and a claim may be reduced without proof, so keep every certificate.
How long will the clean take?
That depends on the size of the system, the amount of grease and the number of access points. Most jobs take anything from a few hours to a full night, depending on the size of the system.
How much notice do you need?
Earlier is better, especially for out-of-hours work. We normally quote within one working day, and emergencies are covered by our 24/7 line.
