Ductwork cleaning for kitchens and businesses in Grovehill
Many ducts were installed with too few access doors. Where a section can’t be reached, TR19 expects it to be recorded on the report, and new panels can be fitted to reach it in future. An honest report beats a guess. If you’re dealing with thick deposits at the bottom of a vertical duct and grease seeping out of the duct seams, we can help, from multi-storey ducts, access panels and horizontal duct runs onwards.
Kitchens around a place like Grovehill are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Your questions about ductwork cleaning in Grovehill
Do you clean school canteen extracts around Grovehill out of term?
Yes, and it’s the easiest time to do it. With about 35 schools and colleges on the FSA’s register within roughly a mile and a half of Grovehill, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Which fire authority looks after Grovehill?
That is Hertfordshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
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.
What if parts of the system can’t be reached?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Can you clean ductwork with no access panels?
Any section we cannot reach is recorded on the report, in line with TR19. New panels can be fitted to reach them in future.
Do you install duct access panels?
Yes, we fit access panels where the duct needs them. It means more of the duct can be cleaned next time, and the report will show where they’re needed.
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Report any grease dripping from duct joints
- Get panels fitted where the duct couldn’t be cleaned
- Never cook with a filter missing
- Keep to the interval on the report
After the clean, the same points are tested again, giving you before and after readings. Photos of each section go alongside them.
Keep the fan on throughout service. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
Leave it or put it right?
TR19® is not law, but the duty to manage fire risk is. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. It’s easy to lose track of when the work was last done on a quieter site.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before we start.

What ductwork cleaning looks like in Grovehill
Look up Grovehill on the FSA’s food hygiene register and you’ll find about 93 restaurants, cafés and works canteens and about 64 sandwich bars and takeaways within about 1.5 miles of central Grovehill. The duct above a busy canopy coats itself in grease long before anyone sees it. Grovehill is covered by Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Kitchens in Grovehill get their food hygiene inspections from Dacorum council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
Historic houses near Grovehill, such as High Elms Manor about 4.8 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hemel Hempstead Hospital is the nearest hospital to Grovehill, about less than half a mile south-west.

Do you need ductwork cleaning in Grovehill?
Damaged or poorly fitted filters let more grease into the duct. The duct then takes grease that the filters should have stopped, and build-up speeds up.
Look out for any of the following:
- Gaps where access panels were never fitted
- Hardened, baked-on grease in long horizontal runs
- A duct nobody has opened in years
- Smells of old cooking grease from the ductwork
If you run a church or community hall kitchen, near Alexandra Road Congregational Church or elsewhere in Grovehill, its extract still collects grease from every lunch and event.
What to look for in a quote
- What insurance they carry
- Whether they recommend a next date
- If they look at the system before pricing
- Whether the whole system is included, or only the parts that are easy to reach
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes anything from a few hours to several visits, depending on the length of duct, and the area is cleaned down before we leave. For a site near Grovehill, the work is booked around your opening hours, evenings and weekends included.
- First the duct route is traced and every access point noted.
- We measure grease thickness at set points before cleaning.
- Access panels are opened and heavy deposits scraped out by hand.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- We test again, take photos and note any part that couldn’t be reached.
Before we arrive
- Tell us about site rules, permits or sign-in
- Arrange a key holder or contact on site
- Let us know about parking and loading
How to get a quote

Advice
What a clean won’t put right
It’s worth knowing the limits before booking:
- Duct sealed behind fixed ceilings or walls

- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we’ll say what we think.

How the job changes from site to site
Horizontal duct runs
The underside of a horizontal duct collects the most grease. Thick deposits are scraped out by hand before degreasing, then the walls and roof are cleaned too.
Multi-storey and shared buildings
Ducts in taller or shared buildings often run past other occupiers. Access is planned with the building’s managers, so the clean is done safely and quietly.
