Ductwork cleaning for sites in Knatts Valley

Ductwork cleaning for kitchens and businesses in Knatts Valley

In doctor’s terms, the ductwork is the system’s 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 pictures. The work covers access panels, multi-storey ducts and horizontal duct runs, and people most often call us about duct runs that can’t be reached and years of grease along the duct floor.

Somewhere as small as Knatts Valley, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.

Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Knatts Valley questions

Who would carry out a food hygiene inspection at a kitchen in Knatts Valley?

In Knatts Valley, it’s Sevenoaks council that carries out food hygiene inspections. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.

Which fire service covers Knatts Valley?

Kent Fire and Rescue Service is the fire and rescue service for Knatts Valley. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Do you install duct access panels?

Yes. The survey or clean shows where sections couldn’t be reached, and fitting them means future cleans are more complete.

Where does the waste go?

It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.

How long does it take to clean extract ducts?

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.

What should I send you?

Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.

Which accreditations do you hold?

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

Do you have insurance?

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

Do you need ductwork cleaning in Knatts Valley?

Many ducts do not have enough access panels. Stretches with no way in may never have been touched, and the grease there keeps building out of sight.

Most sites get in touch when they notice something like this:

  • A grease test showing the duct is overdue
  • Smells of old cooking grease from the ductwork
  • Thick deposits at the bottom of a vertical duct
  • Grease seeping out of the duct seams

If your kitchen is in a listed or historic building, like the houses around Knatts Valley (Lullingstone Castle is about 2.8 miles north-west), fitting access panels needs care.

Our hiring checklist

What affects the cost of ductwork cleaning

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

  • What state the system is in
  • The times the site is available
  • Travel, parking and unloading
  • One-off work versus a regular cycle

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.

Helping us quote

When you contact us, it’s useful to have:

  • Any access panels or hatches you can see
  • Any previous report or certificate
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Wide pictures of the system and the area around it

Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Then call us on 0345 646 2711 or send us an email.

Multi-site and managed buildings

Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

What happens on the day

A visit follows the same order every time: protect the area, make the system safe, carry out the ductwork cleaning, clear away and hand over the paperwork. On site, the work takes anything from a few hours to several visits, depending on the length of duct. The timing of a visit to Knatts Valley is set by you, and the travel is our side of the planning.

  1. Diagnosis: a survey of the duct’s route, size and access.
  2. You get a fixed price before work starts.
  3. We clean section by section, working from panel to panel.
  4. Bends, risers and the base of each riser get extra attention.
  5. Readings, photos and a recommended next clean date complete the job.

Preparing for the visit

  • Mention any sign-in, permit or induction we need
  • Mention any locked doors, roof access or ceiling voids
  • Allow time for equipment near the work to be turned off and cool down

Different parts, different methods

Bends and transitions

A bend can hold far more grease than a straight run of the same length. We clean it back by hand and with degreaser, and test it before and after.

Access panels

Every section of duct is cleaned through an access panel. Without them, parts of the duct can’t be reached and the report has to say so.
