What your team can do, and what needs us

Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

How we handle TR19 inspection in Lower Bourne

Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). The results show whether the system needs cleaning and how soon. If you have heavy grease suspected in the plenum or ducts and parts of the system left out of past cleans, we can help.

Around a smaller place like Lower Bourne, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.

Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What affects the quote in Lower Bourne

The survey tells us what the work involves. We look at:

  • A single visit or a regular plan
  • The scale of the work
  • Where the site is and how we reach it
  • Whether we need access equipment or extra panels

When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before we start.

Helping us quote

Many jobs can be priced from pictures and some basics. Send what you can of the following:

  • The paperwork from the last visit, if you have it
  • The postcode and the type of business
  • Wide photos of the system and the area around it
  • Any symptoms, from odd noises to smells or leaks

To get a fixed quote, call us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.

Do you need TR19 inspection in Lower Bourne?

Looking at a canopy tells you little about what’s in the duct. Clean filters can hide a heavy layer behind them, so readings are the reliable guide.

Clients normally contact us after spotting one of these:

  • Sites with gaps in their extract records
  • Systems cleaned on a calendar with no measurements
  • Cleaning intervals that may not suit the kitchen
  • Checking the result of a recent clean

If you run catering at a historic house or estate in the area (Farnham Castle is about 1.6 miles north), event kitchens in older buildings often have awkward duct runs that need planning.

Questions to ask before you book

  • What happens if part of the system can’t be accessed
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • If the quote is a fixed price or an estimate
  • What records you will receive afterwards

How to choose an extract cleaning contractor

What happens on the day

There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, and that takes a morning or less for one kitchen, more where there are several systems. Because the survey comes first, a visit to Lower Bourne can usually be finished without a second trip.

  1. The visit is arranged for when the kitchen is not busy.
  2. Every part of the system is examined, end to end.
  3. Grease thickness is measured at set points by WFTT or DTT.
  4. We photograph the test points and record any sections we cannot reach.
  5. The findings go into a report with readings, photos and a recommended next clean.

How to prepare

  • Let us know about permits to work or site inductions
  • Tell us the best time to work, such as after service or at a weekend
  • Make sure equipment near the work can be switched off and left to cool

Ask for 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 photos, get a survey first. Either way, the quote is fixed before any work is booked.

Lower Bourne: your questions answered

Which fire service covers Lower Bourne?

Fire safety enforcement in Lower Bourne is handled by Surrey Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Will you come out to Lower Bourne?

Yes. Lower Bourne is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.

What is a WFTT or DTT grease test?

It’s a measurement of how much grease is coating the inside of the extract, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). Each reading is recorded in microns.

Are you accredited?

Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Can you look after several sites?

Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.

Can you set up regular visits?

Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.

Do you look at the system first?

Yes. We always survey first, from your photos and details, or with a visit where needed. Then you get a fixed quote.

What information do you need?

Some photos and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.

Leave it or put it right?

Sites in Lower Bourne that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Testing gives you the evidence to set it properly. A planned visit to Lower Bourne fits your hours; an emergency does not.

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

Multi-site and managed buildings

From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.

Part by part

Vertical risers

Vertical risers take the extract up through the floors. Grease can drain down and pool at the bottom, so the base is a key test point.

Restaurants, pubs and hotels

A kitchen running from breakfast to late service builds grease quickly. Readings show if the cleans are frequent enough.
