Why deal with it now?
Fresh grease comes off far more easily than old. Over months, the heat hardens it into a stubborn coating, which makes a later clean slower and harder. With notice, the visit to Datchworth can be fitted around your bookings and events.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before we start.

Canopy cleaning for kitchens and businesses in Datchworth
Duct Doctor has cleaned canopies and hoods since 2009. As a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, we treat the canopy as one part of a whole system, and we hold CHAS, SafeContractor and ISO 9001. If you’re dealing with a sticky, discoloured canopy and a canopy that no longer draws the smoke away, we can put it right, from island canopies, grease gutters and wall canopies onwards.
Work in a small place like Datchworth starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What affects the quote in Datchworth
You will get a fixed price before any work starts. It takes into account:
- Any permits to work or inductions
- Where the site is and how we reach it
- One-off work versus a regular cycle
- The condition of the system
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before we start.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- Detail shots of panels, filters and grilles
- The site address and the type of premises
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
What we do, step by step
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a few hours for most canopies. If the van will struggle with a lane or gateway near Datchworth, let us know and we will plan around it.
- We look at the canopy first, from photos or on a visit.
- Equipment below is switched off and left to cool, then sheeted.
- Filters come out and the plenum behind them is scraped and degreased.
- We degrease the canopy shell, its seams and the grease troughs.
- We refit the filters, clear up and photograph the finished canopy.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site
- Tell us the best time to work, such as after service or at a weekend

Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, phone us on 0345 646 2711, or send details by email.
Advice
Different parts, different methods
Plenums and filter housings
Filter housings hold the filters in place, and their channels fill with grease. We clean them so the filters sit tight and leave no gaps.
Pub and hotel kitchens
A hotel or pub kitchen can rarely close for long. We clean the canopy overnight or between services so the kitchen keeps trading.
Honest limits
We’d rather tell you now than book work that will not help, so here are the limits:
- Weak extraction caused by a failing fan motor
- Grease filters too damaged to refit (they need replacing)
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
If you’re not sure, just give us a ring on 0345 646 2711, or email photos and we’ll give you a straight answer.

FAQs for Datchworth
Which council inspects kitchens in Datchworth?
That’s East Hertfordshire council, whose environmental health officers carry out food hygiene inspections in Datchworth. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Who is the fire and rescue service for Datchworth?
Datchworth is in the area of Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
How much of the canopy do you clean?
Inside and out, along with its seams and grease channels. The plenum and filter housing behind the filters are cleaned too.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
Do you cover Datchworth?
Yes. We cover Datchworth and across Hertfordshire, within our South East and London area. To book, phone us on 0345 646 2711, or email photos.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
Why does grease run off the canopy edge?
Normally because the troughs or gutters are full, or the plenum is overloaded. Grease has nowhere else to go, so it runs down and drips, and condensation can carry it too. Cleaning the canopy and plenum clears it.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.

Aftercare tips
So the system stays in good health:
- Keep every filter in place while cooking
- Avoid harsh scourers that scratch the canopy
- Run the extract the whole time you’re cooking
- Check and empty canopy gutters regularly
Anything worth knowing goes into the report: damaged filters, gaps around the housing or troughs that need emptying more often. We keep it to what matters.
Tell us if the canopy starts dripping or the filters clog sooner than usual. More drips or quicker clogging often mean the cleaning interval needs looking at, which a grease thickness test can confirm.
