Horton: your questions answered
Can the work in Horton be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Horton keeps running as normal. Let us know the hours you are closed and we’ll book within them.
Do you work in villages like Horton?
Yes. Villages and rural sites across the South East are part of our work, Horton included. Photos of the system and directions to the site help us plan the visit.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
How much does TR19 inspection cost?
Every site is different, so each gets its own fixed quote. For a quote, call us on 0345 646 2711, or send details by email with the site type, opening hours and a few pictures.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
When should we have our next grease test?
It depends on how heavily the kitchen cooks. BESA sets minimum cleaning intervals of 3, 6 or 12 months by daily use, and grease readings help set the real interval.
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). The results are given in microns.
How we handle TR19 inspection in Horton
Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Testing is how you know where your system stands. If you’re dealing with checking the result of a recent clean and systems cleaned on a calendar with no measurements, we can put it right.
In a small place like Horton, 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.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Report grease dripping from the canopy
- Diary the next grease test and clean
- Mention new equipment or longer hours at the next test
- Keep the route to access panels clear
Keep the verification report next to the certificate it relates to. Together they show the system was cleaned and checked.
When cooking hours or the menu change, check the interval still fits. Fresh readings show whether it needs to change.
What we do, step by step
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes around an hour or two per canopy and duct system. The timing of a visit to Horton is set by you, and the travel is our side of the planning.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- You get a report with readings, pictures and recommendations.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear the space around the work
- Make sure someone can let us in and lock up afterwards

Fixed quotes for TR19 inspection in Horton
Every site gets its own quote. This is what makes a difference:
- Whether several sites go on one quote
- Site rules, permits and inductions
- Whether we need access equipment or extra panels
- The times the site is available
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before we start.
What to send for a quote
When you call or email, these details help:
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
What a clean won’t put right
Not every problem is solved by TR19 inspection, and we’d rather say so up front. It does not solve:
- Fan breakdowns, which need a repair visit
- Removing the grease, which is a separate clean
- Installation problems, which fall under design guidance such as DW172
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we will tell you honestly before you book.
Where we work
- Post-clean checks
- Deposit thickness tests
- Insurer audits

Grease, kitchens and Horton
Food Standards Agency records list about 19 cafés, restaurants and staff canteens and about 7 takeaways and sandwich shops within about 1.5 miles of central Horton. Each kitchen extract among them can be measured for grease to set the right cleaning interval. The fire and rescue service for Horton is Royal Berkshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Food hygiene inspections in Horton are the job of Windsor and Maidenhead council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
If you run catering at a healthcare site, such as a hospital like Upton Hospital about 3.3 miles north-west, the extract may need cleaning more often than a part-time kitchen. Church and community hall kitchens, near Church of St Michael or anywhere around Horton, are easy to forget, but their extracts collect grease like any other.

What we’re called out for in Horton
TR19® is the benchmark that insurers, fire officers and EHOs refer to. It is not legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and grease in the extract is part of that risk.
Keep an eye out for any of the following:
- Insurance renewals needing proof of TR19 cleaning
- Pre-clean surveys before a first TR19 clean
- Kitchens whose menu or hours have changed
- Post-clean verification after another contractor’s clean
If you run catering at a historic house or estate in the area (Frogmore House is about 2.5 miles west), event kitchens in older buildings often have awkward duct runs that need planning.
Questions to ask before booking
- Proof of insurance
- How VAT is shown on the quote
- Whether the work can be done while the site is closed
- Whether the figure could change on the day
What your team can do, and what needs us
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
