AHU cleaning in Orsett

About our AHU cleaning in Orsett

We clean air handling units for buildings in Orsett and across Thurrock, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. Common call-outs are for air handling units due a clean after building work and air handling units with blocked filters, on internal panels, dampers and louvres and heating and cooling coils.

For a building in or near Orsett, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.

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 are fully insured.

What affects the quote in Orsett

There’s no set price list, because no two systems are the same. What we look at:

  • Site requirements such as sign-in and permits
  • The number of sites or systems
  • When the work can happen, such as evenings, overnight or weekends
  • The condition we find in the survey

You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.

Asking for a quote

Many jobs can be priced from pictures and some basics. Useful things to send:

  • How we’d reach plant on a roof or in a plant room
  • A few general shots of the system
  • Detail shots of panels, filters and grilles
  • The times we could work without disrupting the site

To get a fixed quote, call us on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.

What happens on the day

Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Orsett, lanes, gates and parking are worth mentioning in advance.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. The unit is shut down with your site team and the area protected.
  3. Filters, coils, fan section and casing are cleaned in turn.
  4. We clean out the drain tray and make sure it drains.
  5. We close up the unit and send the certificate and before and after pictures.

How to prepare

  • Find the previous report, if there is one
  • Tell us the best time to work, such as after service or at a weekend
  • Let us know about permits to work or site inductions

There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, ring 0345 646 2711, or email photos.

Advice

Honest limits

We won’t sell you work that does not address the problem, so here are the limits:

  • Ductwork downstream of the unit, which is a separate clean
  • Controls and BMS settings that run the unit
  • Mechanical faults with motors, belts or bearings

If you’re not sure, just call us on 0345 646 2711 or use the quote form and we’ll give you a straight answer before you book.

Where we work

  • Dampers and louvres
  • Drain trays
  • Heating and cooling coils
  • Supply and extract fans
  • Internal panels
  • Filter sections

Between visits

Once we’ve finished, these simple steps help:

  • Report musty smells from the vents straight away
  • Book the next check in line with the report
  • Change filters on schedule and log each change
  • Watch for drips or damp patches near the plant

The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.

Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.

Managing agents and facilities teams in Orsett

Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.

We also work for facilities teams across offices, schools and healthcare in Orsett and across Thurrock. Larger estates can be phased building by building to keep disruption down.

What the work involves, part by part

Internal casing and panels

Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.

Fans and fan sections

The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.

Your questions about AHU cleaning in Orsett

Can a school’s ventilation in Orsett be done out of term time?

Yes, holiday work suits schools best. Around Orsett, the Food Standards Agency lists about 6 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.

Will you come out to Orsett?

Yes. Villages and rural sites across the South East are part of our work, Orsett included. The journey is planned ahead, so a few details about the route help.

Which sectors do you work in?

Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.

What if parts of the system can’t be reached?

We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.

Do you have insurance?

Yes. We carry full insurance and have been trading since 2009.

Do you do ventilation duct cleaning too?

Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, with new panels fitted where needed.

How long does it take to clean an air handling unit?

It takes from a few hours for a compact unit to a day or more for a large one. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.

Do you give a certificate after the clean?

Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.

Orsett buildings and their air

There are about 6 schools, colleges and universities and about 3 hotels, B&Bs and guest houses on the FSA’s food hygiene register in Orsett and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. The nearest hospital to Orsett is Orsett Hospital, about within half a mile south. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Orsett is about 20 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible.

Wherever a school like Orsett Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. Orsett Hospital, about within half a mile south, is the nearest hospital to Orsett, and healthcare sites of every size need their supply air kept clean.

Staff cleaning versus specialist work

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.

Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
