TR19 inspection in Stone Street
Think of a TR19 inspection as the diagnosis before the treatment. We look at the system, take grease readings and photograph what we find, so the quote and the clean fit the real system. The work covers post-clean checks, deposit thickness tests and wet film thickness tests, and common reasons people get in touch are sites with gaps in their extract records and an insurer’s request for a TR19 audit.
In a small place like Stone Street, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Different parts, different methods
Horizontal duct runs
Grease settles on the floor of horizontal ducts as the air cools. Readings are taken along each run through its access panels.
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so access is planned in advance.
What affects the quote in Stone Street
A fixed price needs a few facts first. We look at:
- How big the system is
- A single visit or a regular plan
- Whether several sites go on one quote
- The condition we find in the survey
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711, or send details by email, and we’ll explain what it covers.
Helping us quote
There’s no need for technical detail. Just send:
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
TR19 inspection in Stone Street: the local picture
Food Standards Agency records list about 4 restaurants, cafés and works canteens within roughly a mile and a half of the centre of Stone Street. Each kitchen extract among them can be measured for grease to set the right cleaning interval. Stone Street is covered by Kent Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. In Stone Street, food businesses are inspected by environmental health officers from Tonbridge and Malling council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Where a hall near St Lawrence, or anywhere in Stone Street, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Ightham Mote, about 1.1 miles south-east, is one of the historic houses near Stone Street; if you run event catering at a venue like that, cleans can be booked between functions. Healthcare kitchens, like those at hospitals such as Sevenoaks Hospital (about 2.8 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands.
Stone Street is about 3 miles east of Sevenoaks, in Kent. Sites in Stone Street get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with pictures. Stone Street is one of 922 towns, villages and districts in Kent we cover for commercial clients. For sites nearby, see our Maidstone page, about 12 miles away.

Landmarks near Stone Street
In Stone Street, that means kitchens and buildings near Sevenoaks Preparatory School, Ivy Hatch Nature Reserve and The Plough pub and the streets around them. The nearest railway station is Kemsing station, roughly 1.9 miles north of the centre. Other landmarks nearby include Ightham Court (2.2 miles north-east) and Sevenoaks Hospital (2.8 miles north-west). Open spaces near Stone Street include Dryhill Nature Reserve.
Leave it or put it right?
If there’s a fire or a claim, your insurer may ask for TR19 records. Missing records can put a claim at risk. An up-to-date inspection report is a good place to start. Out of sight is the usual reason a rural system goes too long without attention.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before work begins.

When it’s something else
In fairness, some problems need a different fix:
- Sections with no access, until panels are fitted
- The legal duty, which stays with the responsible person
- The grease itself, which needs a full or spot clean
If you are not sure, just give us a ring on 0345 646 2711 or drop us a line and we will give you a straight answer before booking.
What the work covers
- Access surveys
- Post-clean checks
- Pre-clean surveys
- Deposit thickness tests
- Insurer audits
- Wet film thickness tests
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Questions from Stone Street
Who enforces fire safety at workplaces in Stone Street?
It’s Kent Fire and Rescue Service, which covers Stone Street. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you come to Stone Street after we close?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Stone Street needn’t be disturbed. Your opening times are the first thing we ask for.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
What grease levels does TR19 allow?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, with 500 microns or more anywhere needing immediate spot cleaning.
Can you verify a clean after it’s been done?
It’s an inspection after cleaning, to show what state the system was left in, for our cleans and other firms’ alike.
Can you quote from pictures?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.
How much does TR19 inspection cost in Stone Street?
Every site is different, so each gets its own fixed quote. To get one, ring 0345 646 2711 or email us with the site type, opening hours and a few photos.
Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.

The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes an hour or two for a single kitchen, longer for a large or complex system. Somewhere like Stone Street, lanes, gates and parking are worth mentioning in advance.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Getting ready for the visit
- Move anything stored near the system
- Tell us the best time to work, such as after service or at a weekend
- Mention any parking or loading restrictions
