Different parts, different methods

Rooftop and plant room units

Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.

Fans and fan sections

Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.

AHU cleaning for kitchens and businesses in Woodside

Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote, so you know where you stand. If you have dirty coils holding back the airflow and plant that needs cleaning after a refit, we can put it right.

In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Woodside is normally planned out of hours. Loading and parking are planned with the building first.

A written report with photos follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Common questions in Woodside

Can the work in Woodside be done at night or at weekends?

Yes, we can come after you close and finish before you open. The work in Woodside can fit around your hours. Let us know the hours you are closed and we’ll book within them.

Can you clean school ventilation in Woodside during the holidays?

Yes, out-of-term visits are normal for schools. There are about 20 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Woodside. You can call 0345 646 2711, or send details by email with the dates the site is empty.

Will we get paperwork for the AHU clean?

Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.

How much does AHU cleaning cost in Woodside?

It depends on the site, so we quote each one individually. For a quote, call 0345 646 2711, or send details by email with the site type, opening hours and a few photos.

Can you quote from photos?

Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.

What is TR19?

A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.

What happens if you cannot reach some of it?

Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.

Do you need to switch the unit off?

Yes, for the time we are working on it. We can work evenings, overnight or at weekends so the building is not left without ventilation when it’s busy.

How it works

At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Woodside.

  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 are dealt with as agreed, and the coils, fan and casing cleaned.
  4. Standing water and slime come out of the tray and the drain is checked.
  5. We close up the unit and send the certificate and before and after pictures.

Before we arrive

  • Plan for cooking equipment or plant to be off before we arrive
  • Clear the space around the work
  • Mention any sign-in, permit or induction we need

How to get a quote

If you need AHU cleaning in Woodside, call 0345 646 2711, or email photos. Let us know the site type and the opening hours, and send pictures or your last report if you can. We typically send a fixed quote within one working day.

Advice

When it’s something else

To be straight with you, some problems need a different fix:

  • Breakdowns that need a mechanical engineer
  • Damaged coils beyond cleaning
  • Ventilation that was badly designed in the first place

Not sure which it is? You can call us on 0345 646 2711, or send details by email and we’ll tell you honestly.

Parts of the system we cover

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

Why deal with it now?

A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Shared walls, risers and roofs mean a problem at one London site seldom stays put.

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

What you get with us

  • We diagnose before we treat
  • A fixed price before any work starts
  • Out-of-hours work and a 24/7 emergency line

Ventilation in Woodside buildings

There are about 20 schools, colleges and universities, about 81 care, childcare and hospital premises and about 6 hotels and guest houses on the FSA’s food hygiene register in Woodside and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot. National Psychosis Unit is the nearest hospital, about 1.7 miles east of Woodside. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.

Multi-site and managed buildings

Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.

If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.

What affects the quote in Woodside

Your quote is based on your site. We consider:

  • The condition of the system
  • Whether we need access equipment or extra panels
  • Working hours and out-of-hours timing
  • A single visit or a regular plan

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 any work starts.

Asking for a quote

To speed up the quote, please include:

  • Your last certificate, test record or report
  • A few general shots of the system
  • Your opening hours and when the area is out of use
  • The roof, plant room or outside wall the system runs to

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

What we’re called out for in Woodside

It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.

These are the problems we see most often:

  • Plant that needs cleaning after a refit
  • Plant that has been serviced but not cleaned
  • Stale or musty smells from the ventilation
  • Dust built up on fan impellers

For workplaces around Norwood Junction station with mechanical ventilation, cleaning can be done in the evening or at weekends.

What your quote should include

  • What paperwork you get at the end
  • If they look at the system before pricing
  • Whether the figure could change on the day
  • What insurance they carry
