When it’s something else

A few issues sit outside what this work can do:

  • Leaking duct joints that need repair
  • Ductwork that was poorly designed
  • Fire dampers that do not close (they need testing and remedials)

If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think before you book.

Ductwork cleaning in Tonwell

We treat ductwork like a doctor treats arteries: diagnose where grease has built up, clear it and confirm the result. Readings taken before and after show the difference, alongside before and after photos. Typical jobs include gaps where access panels were never fitted and proof of duct cleaning for the insurer, on horizontal duct runs, vertical risers and multi-storey ducts.

In a village or hamlet like Tonwell, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.

The report is your 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 affects the cost of ductwork cleaning

You will get a fixed price before we start. It takes into account:

  • The condition of the system
  • The number of sites or systems
  • How easy every part is to reach
  • Parking and loading at the site

You will not find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711 or send us an email, and we’ll talk you through it.

Asking for a quote

Photos let us diagnose from a distance. The most useful are:

  • Your opening hours and when the area is out of use
  • Where the site is and what kind of site it is
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • A few general shots of the system

What happens on the day

When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes from a few hours to more than one visit, depending on duct length and access. In a small place like Tonwell, the journey is planned ahead and the visit arranged around the site’s hours.

  1. Diagnosis: a survey of the duct’s route, size and access.
  2. A fixed quote follows, based on what we found.
  3. Each section is cleaned in turn through its access panel.
  4. Bends, risers and the base of each riser get extra attention.
  5. The duct is signed off with readings, pictures and a next clean date.

Getting ready for the visit

  • Allow time for equipment near the work to be turned off and cool down
  • Make sure someone can let us in and lock up afterwards
  • Let us know how we reach the system, including roofs, risers and plant rooms

Advice

FAQs for Tonwell

Can you work in Tonwell outside opening hours?

Yes, we can come after you close and finish before you open. Your customers, staff or residents in Tonwell needn’t be disturbed. Tell us your opening hours when you ask for a quote.

Who inspects food businesses in Tonwell?

That’s East Hertfordshire council, whose environmental health officers carry out food hygiene inspections in Tonwell. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

Can you quote from pictures?

Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote normally follows within one working day. Some sites still need a visit, and we will say so.

Are you insured?

Yes. We carry full insurance, and we have been trading since 2009.

Can you clean ductwork with no access panels?

Sections out of reach are written down on the report, in line with TR19. New panels can be fitted to reach them in future.

How can I tell if my extract ducts are dirty?

Start with the date of the last clean. No record, or a passed date, means it’s due, and grease readings will confirm how urgent it is.

How much does ductwork cleaning cost in Tonwell?

The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll normally reply within one working day.

Can we book visits on a schedule?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.

Leave it or put it right?

BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean right away. Leaving the duct makes those limits harder to keep to. Systems in rural buildings are often out of sight and out of mind.

No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

Aftercare tips

Good habits slow the build-up between visits. Our tips:

  • Keep the fan on while anything is cooking
  • Diarise the next duct clean
  • Get panels fitted where the duct couldn’t be cleaned
  • Do not block access panels with shelving or stock

You’ll have a recommended date for the next clean, based on the readings and your daily cooking hours, in line with BESA guidance.

Watch for warning signs between cleans: drips from the ductwork, stale smells or a noisy fan. A grease thickness test can confirm whether a spot clean is needed.

In-house cleaning or a specialist?

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

Tonwell kitchens: local notes

Look up Tonwell on the FSA’s food hygiene register and you will find about 4 restaurants, cafés and works canteens in Tonwell and the streets around it, up to about 1.5 miles out. The duct above a busy canopy coats itself in grease long before anyone sees it. Hertfordshire Fire and Rescue Service covers Tonwell. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Kitchens in Tonwell get their food hygiene inspections from East Hertfordshire 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.

Term dates shape school work: for a school like Tonwell St Mary's Church of England Primary School, an extract clean fits neatly into a half-term or summer break. If you run catering at a historic house or estate in the area (Aston Bury is about 4.6 miles north-west), event kitchens in older buildings often have awkward duct runs that need planning. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Tonwell is Hertford County Hospital, about 3 miles south.
