Common questions in Grubb Street
Do you clean school canteen extracts around Grubb Street out of term?
Yes, holiday work suits schools best. Food Standards Agency records list about 8 schools, colleges and universities with registered kitchens within about a mile and a half of Grubb Street. Just give us a ring on 0345 646 2711 or use the quote form with your term dates and we will plan around them.
Who inspects food businesses in Grubb Street?
In Grubb Street, it’s Dartford council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
When should we have our next grease test?
Enough to be sure grease stays within the TR19® Grease figures between cleans. The readings themselves tell you if the interval needs to change.
Do you carry out TR19 audits for insurers?
Yes. We inspect the system and produce a report with grease readings, photos and any inaccessible areas. You can pass it straight to your insurer or broker.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
How much does TR19 inspection cost in Grubb Street?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we’ll usually reply within one working day.
Do you cover Grubb Street?
Yes. We work in Grubb Street and the rest of Kent, within our South East and London area. To book, ring 0345 646 2711 or drop us a line.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
TR19 inspection in Grubb Street, done properly
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. We are often asked to deal with sites with gaps in their extract records and kitchens whose menu or hours have changed, on insurer audits, pre-clean surveys and post-clean checks.
For a kitchen in or near Grubb Street, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
A written report with photos follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Managing agents and facilities teams in Grubb Street
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep grease filters clean and fitted properly
- Flag changes in how much frying the kitchen does
- Have the latest report ready for insurance renewals
- Keep access panels clear and unpainted
The report recommends when the system should next be cleaned and tested, from the measured grease and the kitchen’s hours.
Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.
Why act early in Grubb Street
Catching heavy deposits early keeps the fix small. Ignored, the layer only gets thicker. If the system at a site near Grubb Street fails, there may be nowhere nearby to move to.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before any work starts.
Why choose Duct Doctor in Grubb Street
- Every visit written up, with photos
- A single point of contact for sites across the South East and London
- Out-of-hours work and a 24/7 emergency line

What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a couple of hours for a typical kitchen extract system. Rural roads and tight entrances are worth telling us about before a visit to Grubb Street.
- We go through any past certificates and reports.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and photos recorded.
- We report back with readings and a fixed quote.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know when the site is closed or quiet
- Tell us about site rules, permits or sign-in
Ask for a quote
For a fixed quote, call 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We typically come back within one working day.
Advice
In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Do you need TR19 inspection in Grubb Street?
You can’t judge grease thickness by eye. Clean filters can hide a heavy layer behind them, so readings are the reliable guide.
Signs it’s time to call us include:
- Extracts that may be over the 200 micron mean
- Uncertainty over how often to clean
- Kitchen extract systems with no recent grease readings
- An insurer’s request for a TR19 audit
Where a hall near Church of Saint Mary Magdalene, or anywhere in Grubb Street, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Questions to ask before booking
- If the quote is a fixed price or an estimate
- What insurance they carry
- Whether the work can be done while the site is closed
- How areas they cannot reach will be recorded
Honest limits
We won’t sell you work that does not address the problem, so here are the limits:
- Ductwork that was designed or installed badly
- Mechanical faults in the extract
- The grease itself, which needs a full or spot clean
Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we will tell you honestly before booking.
