Grease filter exchange in Coalhill

Good filters only work when they fit properly. Gaps in the filter bank are a direct route into the plenum and every filter is checked when we swap them. Damaged filters are flagged so they can be replaced. If you are dealing with grease left in baffles after washing and filters so greasy the air can barely pass, we can put it right, from baffle filters, island canopies and wall canopies onwards.

Somewhere as small as Coalhill, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.

We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What happens if it’s left?

Grease-loaded filters are a fire risk in their own right. Flames from the range can be drawn up into the canopy, and from there into the duct. Keeping filters clean takes some of that fuel away. Somewhere as small as Coalhill, losing a kitchen or building to a fault is felt by everyone who uses it.

One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before we start.

In-house cleaning or a specialist?

If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

What grease filter exchange looks like in Coalhill

Look up Coalhill on the FSA’s food hygiene register and you will find about 8 restaurants, cafés and works canteens within roughly a mile and a half of the centre of Coalhill. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. It’s Chelmsford council that sends environmental health officers to food businesses in Coalhill. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. Essex County Fire and Rescue Service covers Coalhill. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.

If you run catering at a healthcare site, such as a hospital like Baddow Hospital about 4.1 miles north, the extract may need cleaning more often than a part-time kitchen. Danbury Place, about 4.5 miles north, is one of the historic houses near Coalhill; if you run event catering at a venue like that, cleans can be booked between functions.

Coalhill is about 3 miles north of Wickford, in Essex. We carry out grease filter exchange for commercial premises of every kind in Coalhill and the rest of Essex.

What a clean won’t put right

We’d rather tell you now than book work that will not help, so here are the limits:

  • Grease deep in the extract system
  • Extraction problems caused by the fan rather than the filters
  • An extract that was undersized from the start

If in doubt, call 0345 646 2711, or email photos and we’ll say what we think.

Where we work

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

Coalhill: your questions answered

Who enforces fire safety at workplaces in Coalhill?

Essex County Fire and Rescue Service is the fire and rescue service for Coalhill. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

Will you come out to Coalhill?

Yes, we work in villages as well as towns, and Coalhill is covered. Let us know about access, parking and anything unusual about getting there when you book.

How long does the visit take?

We will confirm the time with your quote. For a typical site, it takes a short visit, depending on how many filters the canopies hold.

Can we skip TR19 cleans if the filters are changed regularly?

It is not. Clean filters help keep grease down, but the ducts and plenum still need cleaning at the right interval.

Can you set up regular visits?

Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.

What types of premises do you cover?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.

What should go in our maintenance log?

Each report and certificate we give you, kept together in your maintenance log with your in-house cleaning records. BESA advises that certificates record the date, location and technician.

Which accreditations do you hold?

Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

When to call us in Coalhill

Wherever you are, Coalhill included, filter washing is the job that gets skipped when the kitchen is busy. A missed wash or two is all it takes for filters to fill with grease.

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

  • Grease dripping from the canopy
  • Filters that come out of the sink still dirty
  • Filters left unwashed on busy weeks
  • A canopy running with filters missing

Church and community hall kitchens, near Church of St Peter or anywhere around Coalhill, are easy to forget, but their extracts collect grease like any other.

What to look for in a quote

  • Whether they recommend a next date
  • If they look at the system before pricing
  • Whether VAT is included
  • When they can work, and whether that is outside your opening hours

Choosing a duct cleaning contractor

What we do, step by step

Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the grease filter exchange, tidy up and hand over the paperwork. On site, the work takes a short visit, depending on how many filters the canopies hold. Photos of the system and how to reach it help us plan a visit to Coalhill.

  1. We start by noting how many filters you have and what type they are.
  2. Together we set how often the filters should be changed.
  3. Each visit starts with the used filters being removed.
  4. Clean, dry filters are fitted in their place, with no gaps left between them.
  5. If a filter is damaged or the plenum needs attention, we tell you.

Getting ready for the visit

  • Have your last certificate or report to hand
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Agree a time when the area can be out of use

Get a fixed quote

The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Fixed quotes for grease filter exchange in Coalhill

You’ll get a fixed price before we start. It takes into account:

  • Where the site is and how we reach it
  • Working hours and out-of-hours timing
  • The scale of the work
  • Any permits to work or inductions

The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before any work starts.

Helping us quote

We can often survey from photos. Try to include:

  • Any symptoms, from odd noises to smells or leaks
  • Any access panels or hatches you can see
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Wide photos of the system and the area around it

There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, call us on 0345 646 2711 or drop us a line.

Between visits

Once we have finished, these simple steps help:

  • Clean the canopy surfaces regularly
  • Look out for drips from the canopy
  • Keep every filter in place during service
  • Tell us if a filter is bent or damaged

The next exchange is already in the diary. If cooking increases, we can change filters more often to match.

If filters are already dripping, they’re overdue. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.
