About our TR19 inspection in Navestock Side

Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. A TR19 audit sets out the system’s condition, with readings and pictures, for sites in Navestock Side and the rest of Essex. The work covers post-clean checks, pre-clean surveys and wet film thickness tests, and the jobs we see most are heavy grease suspected in the plenum or ducts and missing access panels found on survey.

In a village or hamlet like Navestock Side, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.

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.

Questions from Navestock Side

Which fire authority looks after Navestock Side?

Navestock Side is in the area of Essex County Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

Can you work in Navestock Side outside opening hours?

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. When you ring 0345 646 2711 or email us, mention when the site is quiet.

How do you measure grease in a kitchen extract?

Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, then compare them with the TR19® Grease figures.

What does a pre-clean survey involve?

It’s a look at the whole extract before it’s cleaned, with readings and photos. The survey can be done from photos and details or on site, as suits the job.

What should I send you?

The site address, the type of premises and your opening hours, along with a few pictures and any previous report.

How often should grease be tested?

It depends on how heavily the kitchen cooks. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and testing shows if your kitchen needs more.

Do you look at the system first?

Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.

How long does a TR19 inspection take?

An inspection takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Large or multiple systems take longer, and you can call us on 0345 646 2711 or drop us a line to book it in.

What affects the cost of TR19 inspection

We do not publish a price list, because sites vary so much. The quote depends on:

  • Site requirements such as sign-in and permits
  • Whether we need access equipment or extra panels
  • Travel, parking and unloading
  • The number of sites or systems

You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or use the quote form, and we will talk you through it.

Asking for a quote

When you contact us, it’s useful to have:

  • The roof, plant room or outside wall the system runs to
  • Your last certificate, test record or report
  • Photos showing the whole system and its surroundings
  • Your opening hours and when the area is out of use

The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

For landlords and multi-site operators

We also work for facilities teams across offices, schools and healthcare in Navestock Side and across Essex. Larger estates can be phased building by building to keep disruption down.

Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.

How the job changes from site to site

Horizontal duct runs

If a run has no access panel, we note it so it can be fixed before the clean.

Vertical risers

Risers carry the extract up through the building. Grease can run down and collect at the base, so we check there.

Staff cleaning versus specialist work

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.

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.

TR19 inspection around Navestock Side

The FSA’s data shows about 9 bars, pubs and nightclubs registered within about 1.5 miles of central Navestock Side. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. In Navestock Side, food businesses are inspected by environmental health officers from Brentwood council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Navestock Side sits within the area of Essex County 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.

Hill Hall, about 4.8 miles west, is one of the historic houses near Navestock Side; if you run event catering at a venue like that, cleans can be booked between functions. Healthcare kitchens, like those at hospitals such as Brentwood Community Hospital (about 3.2 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands. A hall kitchen that only cooks for events, whether near Church of St Paul or elsewhere in Navestock Side, still needs its extract cleaned, just less often.
