- Insurers asking for TR19 evidence
- Post-clean verification after another contractor’s clean
The process
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes an hour or two for a single kitchen, longer for a large or complex system. If you can send photos, we can arrive in California knowing what to expect.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- The findings go into a report with readings, photos and a recommended next clean.
How to prepare
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
- Name a contact who can let us in at the agreed time

TR19 inspection in California
Not every kitchen fits neatly into a calendar. In a busy kitchen, grease can build faster than the minimum intervals allow for, which is why measurement matters. Our readings give your risk assessment real numbers to work from. If you have kitchens taken over with no cleaning records and extracts that may be over the 200 micron mean, we can put it right, from access surveys, deposit thickness tests and post-clean checks onwards.
Work in a small place like California starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What else we do in California
Part by part
Vertical risers
Risers carry the extract up through the building. Grease can run down and collect at the base, so the base is a key test point.
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Readings show if the cleans are frequent enough.
Why deal with it now?
After an incident, an insurer can ask to see proof of TR19 cleaning and inspection. Missing records can put a claim at risk. An up-to-date inspection report is a good place to start. A fault that closes a site in a village like California affects everyone who depends on it.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before any work starts.
Why us?
- A fixed price before any work starts
- Fully insured
- Evenings, overnight and weekends, plus 24/7 emergency callout
- One contact for all your sites in London and the South East

Looking after it afterwards
So the system stays in good health:
- Clean grease off the canopy between professional cleans
- Keep TR19 certificates, readings and reports together
- Keep to the recommended interval
- Flag changes in how much frying the kitchen does
The report recommends when the system should next be cleaned and tested, based on the readings and how the kitchen is used.
Keep filters clean and in place. Gaps around filters let grease get past them.
TR19 inspection in California: the local picture
Food Standards Agency data counts about 9 cafés, restaurants and staff canteens within 1.5 miles or so of the middle of California. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. California sits within the area of Royal Berkshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Kitchens in California get their food hygiene inspections from Wokingham council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
Volunteers running a hall kitchen near Church of St James, or anywhere in California, may not know when the extract was last cleaned, and a grease test settles it. Bursars and site managers at schools such as Gorse Ride Junior School tend to book extract cleaning for when the kitchen is empty.
California is about 3 miles south-west of Wokingham, in Wokingham. From the centre of California to the outskirts, TR19 inspection is available to all kinds of commercial premises, from a single unit to a large public building. California is one of 35 towns, villages and districts in Wokingham where we work for commercial clients. Reading is in our area too, about 7 miles from California.

Fixed quotes for TR19 inspection in California
We don’t publish a price list, because sites vary so much. What we look at:
- Site rules, permits and inductions
- Parking and loading at the site
- When the work can happen, such as evenings, overnight or weekends
- The number of sites or systems
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.
Asking for a quote
When you call or email, it’s useful to have:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
Your questions about TR19 inspection in California
Which fire authority looks after California?
It’s Royal Berkshire Fire and Rescue Service, which covers California. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you cover smaller places like California?
Yes, California is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Why survey before a clean?
It’s a look at the whole extract before it’s cleaned, with readings and photos. We can work from photos and details, or visit, whichever suits the system.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
How often should a kitchen extract be inspected?
Each report recommends when to test and clean next, based on the readings and how the kitchen is used. A risk assessment based on measured grease should set the interval.
What accreditations do you have?
Duct Doctor is 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.
When something else is needed
Before you book, it helps to know what’s not included:
- The legal duty, which stays with the responsible person
- Heavy deposits found on test, which still need cleaning
- Mechanical faults in the extract
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly.
What the work covers
- Wet film thickness tests
- Pre-clean surveys
- Insurer audits
- Deposit thickness tests
- Post-clean checks
- Access surveys
When to call us in California
Some parts of a system are hard to reach, and grease can be missed there clean after clean. An inspection of a system in California shows where access panels are missing, so panels can be fitted.
Look out for these warning signs:
- Confirming a clean reached the whole system
- Missing access panels found on survey
- Kitchens taken over with no cleaning records
- Extracts that have never been grease tested
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to California is Wokingham Hospital, about 2.6 miles north-east.
