Ductwork cleaning in Farnborough, done properly

Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, with each certificate issued through the BESCA portal. We’re often asked to deal with proof of duct cleaning for the insurer and grease pooling at the foot of the riser, across bends and junctions, horizontal duct runs and vertical risers.

For a pub, café or restaurant in a town like Farnborough, losing a day’s trade to cleaning is not an option, so cleans are booked after closing, early in the morning or on a quiet day. By the next service, the kitchen is ready to cook in again.

Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What ductwork cleaning can’t fix

To be straight with you, there are a few things this work won’t fix:

  • Fire dampers that do not close (they need testing and remedials)
  • Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
  • Ductwork that was poorly designed

If you’re not sure, just call us on 0345 646 2711, or send details by email and we’ll give you a straight answer before you book.

What the work covers

  • Horizontal duct runs
  • Vertical risers
  • Bends and junctions
  • Attenuators
  • Access panels
  • Multi-storey ducts

What staff can safely do

Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.

What the work involves, part by part

Access panels

We can fit new access panels where the duct needs them, so the next clean reaches more of the system. We’ll recommend where they should go.

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.

Kitchen extracts in Farnborough

The FSA’s food hygiene register includes about 28 pubs and bars and about 5 hotels and B&Bs in and around Farnborough, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Fire safety in Farnborough falls to Hampshire and Isle of Wight Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s Rushmoor council that sends environmental health officers to food businesses in Farnborough. 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.

If you run a church or community hall kitchen, near Church of St Christopher or elsewhere in Farnborough, its extract still collects grease from every lunch and event. For schools such as Tower Hill Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

Common questions in Farnborough

Which fire and rescue service is responsible for Farnborough?

Farnborough is in the area of Hampshire and Isle of Wight Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

Can the work in Farnborough be done at night or at weekends?

Yes, we can come after you close and finish before you open. The work in Farnborough can fit around your hours. Tell us your opening hours when you ask for a quote.

Is TR19 a legal requirement?

No, not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurance policies ask for proof of TR19® cleaning. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.

What happens if there aren’t enough access panels?

We clean everything we can reach and record what we cannot. Extra panels can be installed, and we can do that for you.

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.

Which sectors do you work in?

Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.

What information do you need?

A short description and a few pictures plus the address and your hours. If we need more, we will ask.

What about areas you can’t get to?

We record them on the report, with photos where possible, and we explain what access is needed, for example new access panels.

Leave it or put it right?

Grease narrows the duct and slows the air. Less air moves, so heat and smoke stay in the kitchen while the fan strains and grease can drip from duct joints. In a town like Farnborough, a problem caught early is a planned visit, not an emergency.

We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or email us, and we will explain what it covers.

The process

Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes a few hours for a short run, longer for long runs and tall risers. For a site in a town like Farnborough, tell us your opening hours, where we can park and how we reach the roof or plant.

  1. First we diagnose: the route, the access and the grease levels.
  2. You get a fixed price before work starts.
  3. We clean section by section, working from panel to panel.
  4. We take extra care at bends and at the foot of risers.
  5. The duct is signed off with readings, photos and a next clean date.

Getting ready for the visit

  • Mention any sign-in, permit or induction we need
  • Make sure equipment near the work can be switched off and left to cool
  • Agree a time when the area can be out of use

Getting a quote

Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.

Advice

What affects the quote in Farnborough

Before we fix a price, we need to know a few things. We check:

  • Working hours and out-of-hours timing
  • Parking and loading at the site
  • How big the system is
  • How easy every part is to reach

Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.

Asking for a quote

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

  • The roof, plant room or outside wall the system runs to
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • The postcode and the type of business
  • Your opening hours and when the area is out of use

To help us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Then call 0345 646 2711 or use the quote form.

Signs you need ductwork cleaning in Farnborough

A vertical riser can run up several floors. Grease collects on the riser walls and gathers at the bottom as liquid grease runs down. Panels along the riser make proper cleaning possible.

Any of these means the system needs a check-up:

  • Years of grease along the duct floor
  • Duct runs that cannot be reached
  • A grease test showing the duct is overdue
  • Duct runs with no cleaning record

If you run catering at a healthcare site, such as a hospital like Frimley Park Hospital about 2 miles north-east, the extract may need cleaning more often than a part-time kitchen.

Before booking anyone

  • Whether VAT is included
  • What insurance they carry
  • When they can work, and whether that’s outside your opening hours
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
