Ductwork cleaning for sites in Great Hormead

Ductwork cleaning in Great Hormead

Grease in a duct is hidden, which is exactly why it’s dangerous. Flames pulled in from the cooking line can ignite it, and fire can then run along the ductwork to other parts of the building. Removing it is the whole point. If you’re dealing with thick deposits at the bottom of a vertical duct and duct runs with no cleaning record, we can help, from bends and junctions, horizontal duct runs and attenuators onwards.

In a small place like Great Hormead, 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.

For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

How it works

A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, clear away and hand over the paperwork. On site, the work takes a shift or more, depending on the length of the runs and the number of access points. For a village or hamlet like Great Hormead, tell us about narrow lanes, gates and parking when you book.

  1. We start by working out how the duct runs and where it can be opened.
  2. Set points along the runs are tested for grease.
  3. Through the access panels, thick grease is removed by hand first.
  4. Horizontal runs and risers are then degreased by the method that suits the deposit.
  5. We test again, take photos and note any part that couldn’t be reached.

How to prepare

  • Mention any parking or loading restrictions
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Name a contact who can let us in at the agreed time

How to get a quote

The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

Advice

What we’re called out for in Great Hormead

Ducts in Great Hormead gather grease for the same reasons as ducts anywhere: hours of cooking, the type of food and how well the filters are kept. BESA guidance sets minimum intervals of 3, 6 or 12 months depending on daily use.

Keep an eye out for any of the following:

  • Fat dripping from the ductwork
  • Thick deposits at the bottom of a vertical duct
  • Smells of old cooking grease from the ductwork
  • Gaps where access panels were never fitted

If you look after a school kitchen, at a school such as Hormead Church of England (VA) First School or anywhere near Great Hormead, the holidays are the usual time for a TR19® clean.

Questions to ask before booking

  • If the quote is a fixed price or an estimate
  • Whether a written report and pictures are included
  • Whether they’re fully insured
  • How VAT is shown on the quote

Honest limits

An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:

If in doubt, give us a ring on 0345 646 2711 or use the quote form and we will say what we think.

Great Hormead questions

Can you work in Great Hormead outside opening hours?

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just ring 0345 646 2711 or send us an email with your opening times and we’ll plan around them.

Do you work in villages like Great Hormead?

Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.

How is kitchen extract ductwork cleaned?

We survey the route, test the grease, then open the access panels. We clean the runs and risers section by section, then the readings are repeated.

Are you accredited?

We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.

What happens if you can’t reach some of it?

We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.

Is TR19 a legal requirement?

No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.

What happens if there are not enough access panels?

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

What paperwork do you give after a duct clean?

A full system clean comes with a TR19 certificate and a photo report. It includes readings, pictures and any unreachable sections.

Looking after it afterwards

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

  • Report any grease dripping from duct joints
  • Run the extract fan throughout service
  • Ask for a grease thickness test if the kitchen gets busier
  • Never cook with a filter missing

Grease readings are taken again at the same set points, so the report shows the before and after figures. Photos of each section go alongside them.

Grease that never reaches the duct never needs cleaning out of it. Keep the filters clean, well fitted and in place whenever you cook.

Why it’s worth doing now in Great Hormead

Grease left in a duct in Great Hormead hardens over time. Heat and age turn it into a thick, stubborn crust, which makes each delayed clean a bigger one. In a small place like Great Hormead, a system that fails can take a site out of use.

No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

Different parts, different methods

Access panels

Access panels are the doors that let us into the duct. Where there are none, those sections cannot be cleaned, and TR19 expects them to be recorded.

Attenuators and discharge

The last section of duct before the discharge is often the coolest, so it can collect more grease than expected. We include it in the clean and the readings.

Landlords, agents and facilities managers

Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.

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 photos, so records stay tidy.
