- Uncertainty over how often to clean

Leave it or put it right?
Skipping grease testing leaves the cleaning interval to guesswork. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, which you will not know without measuring. Nothing in a duct, damper or fan improves by being left.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.

TR19 inspection in Amersham
Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. From the numbers, you can see whether cleaning is due. If you are dealing with missing TR19 certificates or history and surveys needed before quoting a full clean, we can put it right, from post-clean checks, wet film thickness tests and pre-clean surveys onwards.
Most kitchens in a town like Amersham can’t close for a day, so the work is done after service, overnight or on a closed day. By the next service, the kitchen is ready to cook in again.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Design faults in the extract system
- The legal duty, which stays with the responsible person
- Heavy deposits found on test, which still need cleaning
If in doubt, call 0345 646 2711 or use the quote form and we’ll say what we think before booking.

FAQs for Amersham
Do you work overnight in Amersham?
Yes, nights and weekends are routine for us. The work in Amersham can fit around your hours. Your opening times are the first thing we ask for.
Which fire authority looks after Amersham?
That is Buckinghamshire Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What about areas you cannot get to?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
What is post-clean verification?
A post-clean check records grease readings and pictures after the work, whoever did the clean.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What information do you need?
A short description and a few photos, with the address and opening hours. If we need more, we’ll ask.
Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.

What happens on the day
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. For a site in a town like Amersham, tell us your opening hours, where we can park and how we reach the roof or plant.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
Before we arrive
- Have your last certificate or report to hand
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
For TR19 inspection in Amersham, call us on 0345 646 2711, or send details by email. Tell us what kind of premises it is and when it’s open, plus pictures or the previous report if they’re to hand. A fixed quote usually follows within one working day.
Advice
What affects the cost of TR19 inspection
We quote each job individually. This is what makes a difference:
- Any permits to work or inductions
- How big the system is
- How easy every part is to reach
- Whether several sites go on one quote
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before we start.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- The times we could work without disrupting the site
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Kitchen extracts in Amersham
The FSA’s food hygiene register shows about 52 restaurants, cafés and canteens and about 15 sandwich bars and takeaways across Amersham and its immediate surroundings (about a mile and a half). A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Amersham is covered by Buckinghamshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Food hygiene inspections in Amersham are the job of Buckinghamshire council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand.
For kitchens close to Amersham station, where the day often starts early and ends late, the extract can be cleaned overnight. If you run a church or community hall kitchen, near St. Michael and All Angels or elsewhere in Amersham, its extract still collects grease from every lunch and event.

What’s near Amersham
Locally, jobs take us to businesses close to The Pheasant Public House, Woodside Junior School and Dr Challoner's Grammar School. There’s a railway station in Amersham itself: Amersham station. A little further out are Amersham Hospital (1.2 miles south-west) and Amersham Fair Organ Museum (under half a mile north-east). The countryside around Amersham includes Sands Bank.
Common problems we fix in Amersham
Looking at a canopy tells you little about what’s in the duct. A system can look clean at the filters and be heavily coated further in, which is why readings matter.
Clients typically contact us when they notice one of these:
- Sites with gaps in their extract records
- Uncertainty over how often to clean
- Parts of the system left out of past cleans
- Surveys needed before quoting a full clean
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Amersham is Amersham Hospital, about 1.2 miles south-west.
What to look for in a quote
- Proof of insurance
- When the next visit should be, and why
- Whether a survey comes first
- Whether the work can be done while the site is closed
What the work involves, part by part
Horizontal duct runs
Bends and long runs can hold heavy deposits, out of sight of the kitchen.
Extract fan and discharge
We look at where the extract discharges outside, since grease reaches the very end of the system.
