Ductwork cleaning near Chelmsford

The process

Each visit runs to the same pattern: protect the area, make the system safe, carry out the ductwork cleaning, tidy up 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. Phased working suits larger sites in a place the size of Chelmsford, with each part handed back before the next starts.

  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, photos and a next clean date.

Preparing for the visit

  • Tell us the best time to work, such as after service or at a weekend
  • Mention any sign-in, permit or induction we need
  • Plan for cooking equipment or plant to be off before we arrive

Getting a quote

Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Then phone us on 0345 646 2711, or email photos.

Advice

About our ductwork cleaning in Chelmsford

Many ducts were installed with too few access doors. TR19 calls for any section we couldn’t reach to be recorded, and new panels can be fitted to reach it in future. It’s better to know than to assume. Typical jobs include grease pooling at the foot of the riser and hardened, baked-on grease in long horizontal runs, on attenuators, horizontal duct runs and vertical risers.

Kitchens in a place the size of Chelmsford are cleaned around trading, not the other way round: after the last cover, before breakfast or on a day the kitchen is shut. Bigger sites can be done kitchen by kitchen, so cooking carries on elsewhere.

Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

How we price ductwork cleaning

The diagnosis comes before the price. The main factors are:

  • A single visit or a regular plan
  • The number of sites or systems
  • When the work can happen, such as evenings, overnight or weekends
  • Parking and loading at the site

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, call 0345 646 2711, or send details by email for straight advice and a fixed quote.

What we need to know

A few details help us quote accurately. When you get in touch, it helps to send:

  • When the site is open and when it’s quiet
  • A few general shots of the system
  • The roof, plant room or outside wall the system runs to
  • Detail shots of panels, filters and grilles

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 we can price many jobs without a visit.

Why it’s worth doing now in Chelmsford

Grease left in a duct in Chelmsford hardens over time. Heat and age turn it into a thick, stubborn crust, so the later the clean, the bigger the job. Several systems on one site in Chelmsford are simpler to look after when the dates are set in advance.

What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.

  • Each visit written up, with photos
  • Fixed quotes, normally within one working day

Do you need ductwork cleaning in Chelmsford?

Grease in a duct running from a kitchen in Chelmsford is as much a fire risk as in any building. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.

Signs it’s time to call us include:

  • A duct nobody has opened in years
  • High readings at a recent grease test
  • Proof of duct cleaning for the insurer
  • Hardened, baked-on grease in long horizontal runs

Term dates shape school work: for a school like Trinity Road Primary School, an extract clean fits neatly into a half-term or summer break.

Questions to ask before booking

  • When they can work, and whether that’s outside your opening hours
  • Proof of insurance
  • Whether the price is fixed
  • What’s included in the scope, part by part

Our hiring checklist

Multi-site and managed buildings

We also work for facilities teams across offices, schools and healthcare across Essex. Larger estates can be phased building by building around the people who use them.

We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

Kitchen extracts in Chelmsford

The FSA’s data shows about 52 pubs, bars and clubs and about 4 hotels, B&Bs and guest houses registered within about 1.5 miles of central Chelmsford. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Chelmsford is covered by Essex County Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Kitchens in Chelmsford get their food hygiene inspections from Chelmsford council. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.

Volunteers running a hall kitchen near Church of the Holy Trinity, or anywhere in Chelmsford, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Chelmsford is Priory Hospital, about within half a mile north.

Different parts, different methods

Vertical risers

Risers are cleaned through panels at different levels. Where it cannot be reached safely, the report says so.

Attenuators and discharge

Near the discharge, the air has cooled the most, so it can collect more grease than expected. It’s tested and cleaned along with the rest.

Your questions about ductwork cleaning in Chelmsford

Do you clean school canteen extracts around Chelmsford out of term?

Yes. The holidays are the usual time for school work. There are about 33 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Chelmsford. You can give us a ring on 0345 646 2711 or use the quote form with the dates the site is empty.

Which environmental health team covers Chelmsford?

In Chelmsford, it’s Chelmsford council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.

Which sectors do you work in?

Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.

What do you need from me for a quote?

Some pictures and a quick description of the system plus the address and your hours. If we need more, we will ask.

What does TR19 mean?

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.

How long will the duct clean take?

It takes a few hours for a short run, longer for long runs and tall risers. The survey tells us how long your duct needs.

How do you know if the ductwork needs cleaning?

A grease thickness test gives the answer. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.

Is Chelmsford in your area?

Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Chelmsford.

Honest limits

It’s worth knowing the limits before booking:

  • Fire dampers that don’t close (they need testing and remedials)
  • A failed fan motor at the end of the duct (a fan repair job)
  • Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)

Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly.
