About our grease filter exchange in New Denham

Baffle filters and mesh filters both fill with grease. Once they’re clogged, airflow drops and the extract struggles. Regular exchange keeps the air moving. The work covers island canopies, wall canopies and baffle filters, and the jobs we see most are drips falling from the filters onto equipment and damaged filters letting grease past.

Somewhere as small as New Denham, 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.

We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Aftercare tips

Results last longer with the right care. Here’s what we suggest:

  • Make sure we can reach the canopy on exchange day
  • Keep the extract on whenever the range is in use
  • Report a dripping canopy early
  • Clean the canopy surfaces regularly

Keep an eye out for filters that have been taken out. A missing filter leaves a gap for grease so tell us if you need a replacement.

Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.

Managing agents and facilities teams in New Denham

We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.

A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. New Denham is covered by Buckinghamshire Fire and Rescue Service.

Common problems we fix in New Denham

Cooking vapour carries grease into the canopy. The filters catch much of it, and day by day they load up until the air can barely get through.

These are the problems we see most often:

  • Missing filters in the filter bank
  • Filter washing that keeps being missed
  • Weak extraction at the canopy
  • Drips falling from the filters onto equipment

If you run a church or community hall kitchen, near St Francis or elsewhere in New Denham, its extract still collects grease from every lunch and event.

Choosing a duct cleaning contractor

What happens on the day

Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. For a village or hamlet like New Denham, tell us about narrow lanes, gates and parking when you book.

  1. First, we record the size, type and number of filters in each canopy.
  2. We agree a schedule that suits how much the kitchen cooks.
  3. Each visit starts with the used filters being removed.
  4. We fit clean filters and check they sit snugly in the housing.
  5. We flag any damaged filters or anything wrong with the canopy.

Before we arrive

  • Plan for cooking equipment or plant to be off before we arrive
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Tell us the best time to work, such as after service or at a weekend

How to get a quote

Advice

What grease filter exchange cannot fix

A few issues sit outside what this work can do:

  • A canopy that doesn’t capture the vapour properly
  • A fan that is failing or too weak for the system
  • Greasy ducts and risers that a filter change will not reach

If you’re not sure, just ring 0345 646 2711 or drop us a line and we will give you a straight answer.

Where we work

  • Island canopies
  • Baffle filters
  • Wall canopies
  • Mesh filters
  • School and hospital kitchens
  • Restaurants and pubs

What happens if it’s left?

Clogged filters choke the extract. The kitchen gets hotter and smokier, and the fan works harder to pull air through. A regular exchange keeps the airflow where it should be. It’s worth booking a check, because nobody sees inside a duct day to day.

Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we will price it together.

Why book with us

  • Photo reports with every job
  • Survey first, then a fixed quote
  • Fully insured

New Denham: your questions answered

Can you work in New Denham outside opening hours?

Yes, nights and weekends are routine for us. The work in New Denham can fit around your hours. Your opening times are the first thing we ask for.

Do you do school kitchen extract cleaning in New Denham in the summer holidays?

Yes. The holidays are the usual time for school work. Around New Denham, the Food Standards Agency lists about 10 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.

What’s TR19?

TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

Is there a survey before the work?

Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.

Can you look after several sites?

Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.

Will you tell us when the next visit is due?

Yes. The recommended date is on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, while fire dampers are tested at least annually.

Is TR19 cleaning required by law?

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, which applies in England and Wales.

Are you accredited?

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

How we price grease filter exchange

A fixed price needs a few facts first. We look at:

  • Working hours and out-of-hours timing
  • Whether it’s a one-off visit or part of a schedule
  • Site rules, permits and inductions
  • What state the system is in

When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before we start.

Asking for a quote

Photos and a few facts are often enough to price the work. Useful things to send:

  • The roof, plant room or outside wall the system runs to
  • When the site is open and when it’s quiet
  • Wide pictures of the system and the area around it
  • Problems your staff have spotted
