Ductwork cleaning across Burnham Green

What happens on the day

At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes anything from a few hours to several visits, depending on the length of duct. For a village or hamlet like Burnham Green, tell us about narrow lanes, gates and parking when you book.

  1. We map the duct route and check where the access panels are.
  2. Grease readings are taken at set points along the duct.
  3. Through the access panels, thick grease is removed by hand first.
  4. The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
  5. Post-clean readings and pictures go into the report, with any unreachable section listed.

Getting ready for the visit

  • Mention any sign-in, permit or induction we need
  • Tell us the best time to work, such as after service or at a weekend
  • Let us know how we reach the system, including roofs, risers and plant rooms

How we handle ductwork cleaning in Burnham Green

Grease in a duct is hidden, which is exactly why it’s dangerous. Flames pulled in from the cooking line can ignite it, carrying a fire along the duct and into rooms far from the kitchen. Removing it is the whole point. We are often asked to deal with proof of duct cleaning for the insurer and grease seeping out of the duct seams, on multi-storey ducts, access panels and vertical risers.

Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.

The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Part by part

Vertical risers

In taller buildings, a riser may pass through several floors and fire compartments, so fire dampers may be fitted where it crosses them. We test those as a separate job.

Attenuators and discharge

At the end of the duct is the discharge. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.

What affects the cost of ductwork cleaning

Your quote is based on your site. We take into account:

  • Any permits to work or inductions
  • What state the system is in
  • Where the site is and how we reach it
  • How easy every part is to reach

A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before work begins.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in touch, it helps to send:

  • When the site is open and when it’s quiet
  • Wide pictures of the system and the area around it
  • Where the site is and what kind of site it is
  • The roof, plant room or outside wall the system runs to

The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Why deal with it now?

Dealing with the ductwork in Burnham Green now beats dealing with it after a problem. The work takes a few hours for a short run, longer for long runs and tall risers, done out of hours so the kitchen keeps cooking. Planning a trip to Burnham Green ahead is easier for everyone than a rushed one.

Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before work begins.

Between visits

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

  • Check readings when the menu changes
  • Run the extract fan throughout service
  • Never cook with a filter missing
  • Report any grease dripping from duct joints

After the clean, the same points are tested again, so the report shows the before and after figures. Photos of each section go alongside them.

The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.

Your questions about ductwork cleaning in Burnham Green

Who enforces fire safety at workplaces in Burnham Green?

It’s Hertfordshire Fire and Rescue Service, which covers Burnham Green. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Do you work at weekends in Burnham Green?

Yes, we can come after you close and finish before you open. It means the site in Burnham Green keeps running as normal. Let us know the hours you are closed and we’ll book within them.

Can you come out in an emergency?

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.

Can you set up regular visits?

Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.

How can I tell if my extract ducts are dirty?

We measure it. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. A mean above 200 microns, or 500 microns at any point, means it’s due.

Can you look after several sites?

Yes. You deal with one contact for every site in our area, with visits on a regular schedule.

Is there a survey before the work?

Yes. We always survey first, from your photos and details, or with a visit where needed. A fixed quote follows.

What happens if there aren’t enough access panels?

Ductwork needs access to be cleaned. We record those sections on the report and can fit access panels.

What ductwork cleaning looks like in Burnham Green

Food Standards Agency data counts about 7 cafés, restaurants and staff canteens in and around Burnham Green, up to about a mile and a half out. The duct above a busy canopy coats itself in grease long before anyone sees it. In Burnham Green, food businesses are inspected by environmental health officers from East Hertfordshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. Burnham Green sits within the area of 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.

Bursars and site managers at schools such as Monk's Walk School tend to book extract cleaning for when the kitchen is empty. Healthcare kitchens, like those at hospitals such as Queen Elizabeth II Hospital (about 3.6 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands. If you run catering at a historic house or estate in the area (Digswell House is about 1.9 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning.

Landlords, agents and facilities managers

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.

For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.
