Leave it or put it right?

A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. A busy site in Stepney builds up dirt and wear quickly, so putting it off makes the eventual job larger.

You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.

AHU cleaning in Stepney, done properly

A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. Common call-outs are for condensate trays that won’t empty and dirty coils holding back the airflow, across heating and cooling coils, drain trays and supply and extract fans.

London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Stepney is normally planned out of hours. Parking and loading are agreed with the building in advance.

It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

AHU cleaning around Stepney

There are about 89 schools, colleges and universities, about 64 hospitals, care homes and childcare premises and about 39 hotels and guest houses on the FSA’s food hygiene register across Stepney and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Stepney’s nearest hospital, The Royal London Hospital, is about under half a mile west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Ventilation cleaning in London buildings is typically planned for evenings or weekends.

If you manage shops or offices close to Whitechapel station, a TR19® Air inspection shows whether the ductwork needs cleaning. If you manage a school such as Redlands Primary School, ventilation cleaning is best booked for the holidays. Hospitals such as The Royal London Hospital (about under half a mile west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Stepney are no different.

Stepney is about 2 miles south of Hackney, in Greater London. Stepney gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with photos. Stepney is one of 764 places in Greater London we cover for AHU cleaning.

The process

There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes from a few hours for a compact unit to a day or more for a large one. We fit London jobs around the building rather than the other way round, so a visit in Stepney is typically out of hours.

  1. We look at the unit and the plant area during the survey.
  2. We sheet the area and the unit is isolated.
  3. Dirt and debris are removed from each section.
  4. We clean the coils and clear the tray and drain.
  5. We close every panel, hand the unit back and send the report and certificate.

How to prepare

  • Plan for cooking equipment or plant to be off before we arrive
  • Clear the space around the work
  • Let us know when the site is closed or quiet

Different parts, different methods

Heating and cooling coils

Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.

Drain trays

Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.

How we price AHU cleaning

The diagnosis comes before the price. The main factors are:

  • The number of sites or systems
  • Parking and loading at the site
  • The condition of the system
  • Whether it’s a one-off visit or part of a schedule

Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.

What to send for a quote

Before you ask for a quote, gather:

  • Any access panels or hatches you can see
  • 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

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Between visits

No system stays clean for ever, but care slows the build-up. A few tips:

  • Report musty smells from the vents straight away
  • Plan the next inspection before the last report gets filed away
  • Keep inspection doors on the unit in good order
  • File each AHU report in the maintenance log

The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.

Change or clean filters on time. Once filters clog, dirt starts getting past them.

What a clean will not put right

It’s worth knowing the limits before booking:

  • Leaking heating or cooling coils
  • Ductwork downstream of the unit, which is a separate clean
  • Airflow problems caused by the system’s design

If you are not sure, just call us on 0345 646 2711, or send details by email and we will give you a straight answer.

Managing agents and facilities teams in Stepney

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.

Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.

Your questions about AHU cleaning in Stepney

Is parking a problem for work in Stepney?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.

Do you work overnight in Stepney?

Yes, out-of-hours work is a big part of what we do. That way a site in Stepney does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.

When should our AHU next be cleaned?

Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.

Where does the waste go?

Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We do not leave it behind.

Will the ventilation be off while you clean?

Yes. We cannot clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.

Which sectors do you work in?

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

Do you have a 24/7 line?

Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.

Do you offer maintenance contracts?

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