Kitchen extract cleaning in Grubb Street, done properly
Every time food is cooked, warm vapour carries fat up into the extract. It cools inside the duct and settles as a sticky film that thickens month by month. That film is fuel, and a proper clean removes it before it becomes a fire risk. We’re often asked to deal with a system with no record of a TR19 clean and fat running down the canopy edge, on discharge points, canopies and hoods and vertical risers. Extraction cleaning, hood cleaning and TR19 duct cleaning all end up in the same place: a system that is clean inside, not just on the surface, and a certificate that proves it.
BESA sets minimum intervals by hours of cooking a day: every 3 months for 12–16 hours, every 6 months for 6–12 hours and every 12 months for 2–6 hours, adjusted by what the grease readings show.
Work in a small place like Grubb Street starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Duct Doctor has been trading since 2009, as 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.

Questions from Grubb Street
Do you clean school canteen extracts around Grubb Street out of term?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 8 schools, colleges and universities with registered kitchens within about a mile and a half of Grubb Street. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you get to a site in Grubb Street?
Yes, Grubb Street is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Is a quote from photos possible?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
What happens if you can’t reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
How long will the clean take?
Length of duct, grease levels and access all affect it. As a guide, it takes as long as the system needs, from a few hours to several planned visits.
Are you a BESCA Vent Hygiene Elite member?
We are members of Vent Hygiene Elite, the scheme run by BESCA, and we clean to BESA TR19® Grease. We hold CHAS, SafeContractor and ISO 9001 too, and we’re fully insured.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then give us a ring on 0345 646 2711 or drop us a line.
Different parts, different methods
Ductwork and risers
Bends and changes of direction trap more grease than straight runs. We test at points like these before and after cleaning, so the report shows the difference.
Canopy and plenum
Behind the grease filters sits the plenum, which daily cleaning never reaches. We take the filters out and clean the plenum and housing thoroughly.
Fixed quotes for kitchen extract cleaning in Grubb Street
Sites vary more than people expect. The main factors:
- Access, including roofs, risers and ceiling voids
- Working hours and out-of-hours timing
- Site requirements such as sign-in and permits
- How many systems or sites are involved
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before we start.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- Photos showing the whole system and its surroundings
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
Want a quote for kitchen extract cleaning? Please give us a ring on 0345 646 2711 or drop us a line and tell us about the site. We will talk you through the work and give you a fixed quote before you commit to anything.
For landlords and multi-site operators
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
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. Where responsibility is shared, records matter even more.
What happens if it’s left?
After a fire, one of the first questions is often when the extract was last cleaned. Many policies require cleaning to TR19, and an insurer can refuse or reduce a claim without proof. A current certificate is far easier to produce than an explanation. In a small place like Grubb Street, a system that fails can take a site out of use.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.

Kitchen extract cleaning in Grubb Street: the local picture
The Food Standards Agency lists about 4 bars, pubs and nightclubs as registered food businesses within 1.5 miles or so of the middle of Grubb Street. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kent Fire and Rescue Service covers Grubb Street. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. In Grubb Street, food businesses are inspected by environmental health officers from Dartford council. 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.
A hospital like Darent Valley Hospital, about 2.3 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Lullingstone Castle, about 5 miles south-west, is one of the historic houses near Grubb Street; if you run event catering at a venue like that, cleans can be booked between functions. Volunteers running a hall kitchen near Church of Saint Mary Magdalene, or anywhere in Grubb Street, may not know when the extract was last cleaned, and a grease test settles it.

For rail, the closest station is Longfield station, about 1 mile south-east of the centre. Other landmarks nearby include Stone Castle (2.6 miles north) and Darent Valley Hospital (2.3 miles north-west). Green spaces nearby include Sawyers Lake.
What we do, step by step
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes one visit for most kitchens, while large or complex systems may need more than one. Rural roads and tight entrances are worth telling us about before a visit to Grubb Street.
- First the diagnosis: a survey of the whole system and its access points.
- We record grease levels at set points, then fix the price.
- We arrive after close, protect the area and contain the waste.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
Before we arrive
- Move anything stored near the system
- Mention any parking or loading restrictions
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote
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 any work starts.

Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Keep grease collection points emptied
- File each certificate with the fire risk assessment
- Report grease drips, smells or fan noise right away
- Give the canopy a daily wipe
You leave with a date for the next clean, based on your cooking hours and the grease we measured. A 3, 6 or 12-monthly maintenance plan keeps it on track, so the date is not missed.
Wipe the canopy down regularly and empty grease troughs or collection points. A daily wipe is not a deep clean, but it helps between visits.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
