Duct cleaning in Aldenham
Ductwork cleaning across Aldenham and nearby, timed so the site keeps working and finished with a written report and pictures.

- Grease leaking from duct joints
- Grease pooling at the foot of the riser
About our ductwork cleaning in Aldenham
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 we can fit new access panels so it’s cleaned next time. An honest report beats a guess. If you are dealing with grease leaking from duct joints and smells of old cooking grease from the ductwork, we can put it right.
For a kitchen in or near Aldenham, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
The sign-off is always in writing: a dated report with photos 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.

What affects the quote in Aldenham
Sites vary more than people expect. The main factors:
- How easy every part is to reach
- The number of sites or systems
- How big the system is
- Parking and loading at the site
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.
What we need to know
What to send for a quote:
- Any previous report or certificate
- Photos showing the whole system and its surroundings
- When the site is open and when it’s quiet
- The postcode and the type of business
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Questions from Aldenham
Who carries out food hygiene inspections in Aldenham?
In Aldenham, it’s Hertsmere council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Which fire authority looks after Aldenham?
It’s Hertfordshire Fire and Rescue Service, which covers Aldenham. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Will I get a report after the ducts are cleaned?
You get a photo report with before and after photos, plus a TR19 certificate when the whole system is cleaned. Keep both in the maintenance log.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
Can you quote from photos?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.

Aldenham kitchens: local notes
According to Food Standards Agency records, there are about 7 pubs and bars in Aldenham and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Aldenham sits within the area of Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Food hygiene inspections in Aldenham are the job of Hertsmere council’s environmental health team. 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.
A hospital like Watford General Hospital, about 2.8 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Bursars and site managers at schools such as Fair Field Junior School tend to book extract cleaning for when the kitchen is empty.
Aldenham is about 2 miles east of Watford, in Hertfordshire. Whether your site is in the middle of Aldenham or further out, we cover ductwork cleaning for every kind of premises, from a single unit to a large public building. Aldenham is one of 381 places in Hertfordshire where we work for commercial clients. You can also see our page for London, about 16 miles away.

Around Aldenham
Locally, jobs take us to businesses close to Three Compasses Public House, Garston Park and Queens' School and the streets around them. Aldenham’s nearest station is Garston station, roughly 1.4 miles north-west of the centre. A little further out are Hilfield Castle (1.7 miles south-east) and Watford General Hospital (2.8 miles south-west). For a walk, there’s Stanmore Common.
Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Consider fitting panels where the report shows gaps
- Keep to the interval on the report
- Store the certificate with the fire risk assessment
- Don’t switch the extract off early
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
Keep the fan on throughout service. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, and that takes anything from a few hours to several visits, depending on the length of duct. Pictures of the system and its access let us plan the work in Aldenham before we set off.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access panel.
- We take extra care at bends and at the foot of risers.
- The duct is signed off with readings, pictures and a next clean date.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, call 0345 646 2711 or email us.
Related advice
Signs you need ductwork cleaning in Aldenham
A duct with too few access doors cannot be fully cleaned. Sections between panels go uncleaned, sometimes since the system was installed, and the grease there keeps building out of sight.
Most sites get in touch after spotting one of these:
- High readings at a recent grease test
- A duct clean needed for an insurer
- Duct runs that cannot be reached
- A rancid smell from the extract duct
Where a hall near Church of St John the Baptist, or anywhere in Aldenham, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
What your quote should include
- Whether a survey comes first
- Proof of accreditation you can verify
- Proof of insurance
- Exactly which parts of the system are covered
When something else is needed
Not every problem is solved by ductwork cleaning, and we’d rather say so up front. It doesn’t solve:
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- A failed fan motor at the end of the duct (a fan repair job)
- Fire dampers that don’t close (they need testing and remedials)
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we will say what we think before you book.
What the work covers
- Attenuators
- Access panels
- Multi-storey ducts
- Bends and junctions
- Vertical risers
- Horizontal duct runs
Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Managing agents and facilities teams in Aldenham
If you look after several sites, we can schedule visits across all of them on one quote. 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.
