AHU cleaning near Dagenham Green

How we handle AHU cleaning in Dagenham Green

All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. The work covers internal panels, dampers and louvres and supply and extract fans, and the jobs we see most are drain trays holding standing water and air handling units with blocked filters.

London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Dagenham Green, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.

For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.

When something else is needed

AHU cleaning can’t fix everything, and we’d rather say so up front. It won’t put right:

  • A system that is undersized for the building
  • Damaged coils beyond cleaning
  • Breakdowns that need a mechanical engineer

Not sure which it is? You can give us a ring on 0345 646 2711 or send us an email and we’ll tell you honestly.

Where we work

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

Signs you need AHU cleaning in Dagenham Green

Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.

What we’re most often called out for:

  • Air handling units with blocked filters
  • Odours coming through the supply air
  • Drain trays holding standing water
  • Plant that has been serviced but not cleaned

Healthcare buildings such as Barking Community Hospital, about 2.3 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Dagenham Green, yours matters too.

What to look for in a quote

  • Whether the figure could change on the day

Our hiring checklist

Ventilation in Dagenham Green buildings

Going by the FSA’s register, there are about 23 schools, colleges and universities and about 17 caring premises (care homes, nurseries and hospitals) serving food across Dagenham Green and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. About 2.3 miles west of Dagenham Green is Barking Community Hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. In London, ventilation plant is often on the roof or below ground, so the work is usually done out of hours.

School buildings such as Marsh Green Primary School are usually done in the holidays, so classrooms are not disturbed. If you manage shops or offices close to Dagenham Dock station, a TR19® Air inspection shows whether the ductwork needs cleaning.

Why deal with it now?

If people in a building in Dagenham Green complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. Shared walls, risers and roofs mean a problem at one London site seldom stays put.

What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before we start.

  • Evenings, overnight and weekends, plus 24/7 emergency callout
  • One contact for all your sites in London and the South East
  • Fully insured
  • A written report with photos after each visit

Aftercare tips

After the visit, a few habits help the work last:

  • Flag stale or damp smells in the supply air
  • Watch for drips or damp patches near the plant
  • Keep the certificate and photo report with the plant records
  • Plan the next inspection before the last report gets filed away

Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.

Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.

Staff cleaning versus specialist work

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.

FAQs for Dagenham Green

Is parking a problem for work in Dagenham Green?

London parking can be tight, so details of loading bays and permits help. If the building has a loading slot system, we’ll book into it.

Can you work in Dagenham Green outside opening hours?

Yes, out-of-hours work is a big part of what we do. That way a site in Dagenham Green does not have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.

Do you work in Dagenham Green?

Yes. Dagenham Green is part of the area we cover, as part of our area across London and the South East.

Can you set up regular visits?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.

What’s TR19?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.

Do you give a certificate after the clean?

Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.

How long does an AHU clean take?

The work takes anything from half a day for one small unit to several shifts for a plant room full of them. Bigger units can be phased, and you can call 0345 646 2711 or drop us a line to plan it.

How far ahead should we book?

That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.

What we do, step by step

Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, clear away and hand over the paperwork. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Before any visit in Dagenham Green, we agree where the van can stop and how equipment reaches the system.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. Before cleaning, each section is photographed.
  3. We work through the unit from the intake to the outlet.
  4. The fan and drain tray are cleaned and the drain checked.
  5. After photos are taken and the certificate issued.

How to prepare

  • Have your last certificate or report to hand
  • Name a contact who can let us in at the agreed time
  • Tell us about site rules, permits or sign-in
