Biggin Hill: your questions answered

Can the work in Biggin Hill be done at night or at weekends?

Yes, we can come after you close and finish before you open. It means the site in Biggin Hill keeps running as normal. Just phone us on 0345 646 2711 or drop us a line with your opening times and we will plan around them.

Can a school canteen extract in Biggin Hill be done out of term time?

Yes. Half-terms and the summer break are the natural time for school work. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Biggin Hill. Booking early in the term gives the best choice of holiday dates.

Do you have insurance?

Yes. Full insurance covers our work and have been trading since 2009.

What happens to the waste?

Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.

Do you survey before quoting?

Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.

How much does ductwork cleaning cost in Biggin Hill?

Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll typically reply within one working day.

Are you accredited?

BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we are fully insured.

How can I tell if my extract ducts are dirty?

The date on the last certificate is the first thing to check. No record, or a passed date, means it’s due, and grease readings will confirm how urgent it is.

How we handle ductwork cleaning in Biggin Hill

We treat ductwork like a doctor treats arteries: diagnose where grease has built up, clear it and confirm the result. Grease readings before and after give you the evidence, alongside before and after photos. The work covers horizontal duct runs, bends and junctions and access panels, and people most often call us about years of grease along the duct floor and ductwork that has never been cleaned.

London kitchens tend to trade late and open early, so extract cleaning in Biggin Hill is usually done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.

Good records are part of the job. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What affects the quote in Biggin Hill

The price is fixed before any work begins. It takes into account:

  • The condition of the system
  • When the work can happen, such as evenings, overnight or weekends
  • Site rules, permits and inductions
  • The number of sites or systems

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 any work starts.

Helping us quote

You do not need the technical terms. It helps if you can send:

  • Your last certificate, test record or report
  • The site address and the type of premises
  • Your opening hours and when the area is out of use
  • Close-ups of filters, grilles, hatches or access panels

Need a price for ductwork cleaning? Please give us a ring on 0345 646 2711 or use the quote form and tell us about the site. We will explain what we’d do and send a fixed quote before anything is booked.

Different parts, different methods

Attenuators and discharge

Some systems have attenuators to reduce noise, and their linings can soak up grease. We clean what can be reached and note anything that can’t.

Multi-storey and shared buildings

Ducts in taller or shared buildings often run past other occupiers. Access is planned with the building’s managers, so the clean is done safely and quietly.

How the visit works

We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a few hours for a short run, longer for long runs and tall risers. A name and number for whoever controls access to the building in Biggin Hill saves time on the night.

  1. First we diagnose: the route, the access and the grease levels.
  2. A fixed quote follows, based on what we found.
  3. Each section is cleaned in turn through its access panel.
  4. We take extra care at bends and at the foot of risers.
  5. Readings, pictures and a recommended next clean date complete the job.

How to prepare

  • Mention any sign-in, permit or induction we need
  • Let us know about parking and loading
  • Mention any locked doors, roof access or ceiling voids

Getting a quote

Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before we start.

Advice

Why deal with it now?

TR19® is not law, but the duty to manage fire risk is. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. In Biggin Hill, as across London, ductwork often passes through shared risers and other people’s space.

Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

Between visits

How long the results last depends on use and care. We suggest:

  • Ask us about extra access panels where sections cannot be reached
  • Diarise the next duct clean
  • Keep your cleaning records together
  • Report any grease dripping from duct joints

A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.

Grease that never reaches the duct never needs cleaning out of it. Clean, properly seated filters are the duct’s best protection.

What staff can safely do

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
