About our ductwork cleaning in Maple Cross
Each extract duct we take on in Maple Cross goes through the full routine: readings at set points, heavy grease scraped out by hand, then degreasing to suit the deposit. Post-clean readings and pictures complete the record. If you have years of grease along the duct floor and high readings at a recent grease test, we can help.
In a small place like Maple Cross, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What ductwork cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what ductwork cleaning will not do:
- A failed fan motor at the end of the duct (a fan repair job)
- Undersized or badly laid-out ducts
- Duct sealed behind fixed ceilings or walls
If in doubt, give us a ring on 0345 646 2711, or email photos and we’ll say what we think.
Where we work
- Attenuators
- Multi-storey ducts
- Horizontal duct runs
- Bends and junctions
- Access panels
- Vertical risers
When to call us in Maple Cross
Air cools as it moves away from the canopy. Cooling air drops its grease onto the inside of the duct, so duct runs keep collecting grease long after the canopy.
If you notice any of these, it’s worth a diagnosis:
- Thick crusts of old grease along the duct
- A rancid smell from the extract duct
- Ductwork that has never been cleaned
- Grease pooling at the foot of the riser
Healthcare kitchens, like those at hospitals such as Harefield Hospital (about 1.7 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Common questions in Maple Cross
Which fire service covers Maple Cross?
Maple Cross 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.
Which council inspects kitchens in Maple Cross?
Food hygiene inspections in Maple Cross are carried out by Three Rivers council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
How often should kitchen ducts be cleaned?
The duct is cleaned as part of the whole system, at intervals set by BESA guidance, from every 3 months for heavy use to every 12 months for light use. Grease thickness testing shows whether that’s often enough.
What do you need from me for a quote?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then ring 0345 646 2711 or drop us a line.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Can you price the work without visiting?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
When is the ductwork cleaned?
Only while we’re working, and we work around you. Most kitchens book overnight or weekend cleans, so no service is lost.
Why deal with it now?
A dirty duct is something insurers ask about. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. Your certificate and photo report show the ducts were cleaned. A fault that closes a site in a village like Maple Cross affects everyone who depends on it.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.

What else we do in Maple Cross
What the work involves, part by part
Vertical risers
A riser takes the duct up through one or more floors. Grease runs down the walls and gathers at the base, which is one of the points we test.
Horizontal duct runs
A long flat run can’t be cleaned from one end. Where the gaps between panels are too long, we record what couldn’t be reached and can fit extra panels.
Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Maple Cross kitchens: local notes
The Food Standards Agency lists about 5 pubs and bars as registered food businesses within about 1.5 miles of central Maple Cross. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Fire safety in Maple Cross falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. It’s Three Rivers council that sends environmental health officers to food businesses in Maple Cross. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready.
Church and community hall kitchens, near Church of St Thomas of Canterbury or anywhere around Maple Cross, are easy to forget, but their extracts collect grease like any other.

The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes from a few hours to more than one visit, depending on duct length and access, and we clear up before we go. Somewhere as small as Maple Cross, the date and timings are agreed with you well before the day.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about permits to work or site inductions
