About our AHU cleaning in Barnes Cray

Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. Common call-outs are for stale or musty smells from the ventilation and blocked condensate drains and slimy trays, on heating and cooling coils, filter sections and dampers and louvres.

Around a place like Barnes Cray, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.

Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Your questions about AHU cleaning in Barnes Cray

Can you get to a site in Barnes Cray?

Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.

Do you clean school ventilation in Barnes Cray in the holidays?

Yes, out-of-term visits are normal for schools. Around Barnes Cray, the Food Standards Agency lists about 22 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call 0345 646 2711 or use the quote form, and we’ll fit the work in.

Do you do ventilation duct cleaning too?

Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.

What happens if you can’t reach some of it?

We record them on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.

Do you survey before quoting?

Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.

Do you offer emergency callouts?

Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.

How do you keep the site clean during the work?

With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.

Do you give a certificate after the clean?

Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.

What happens on the day

There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes one overnight shift for many single units, with bigger plant phased. Everything the job in Barnes Cray needs is worked out beforehand, from the survey.

  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. Drain trays are cleared and cleaned and the outlet checked.
  5. A TR19® certificate and photo report follow the clean.

How to prepare

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Clear the space around the work
  • Agree a time when the area can be out of use

Getting a quote

Getting a quote doesn’t take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Advice

What the work involves, part by part

Internal casing and panels

We open each section through its doors and close them securely when we are done before the unit is handed back.

Rooftop and plant room units

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

When it’s something else

In fairness, some problems need a different fix:

  • The supply and extract ducts, quoted separately
  • Damaged coils beyond cleaning
  • Airflow problems caused by the system’s design

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

What the work covers

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

Ventilation in Barnes Cray buildings

Food Standards Agency records list about 22 schools, colleges and universities, about 29 caring premises (care homes, nurseries and hospitals) and about 3 hotels and B&Bs registered as food businesses in and around Barnes Cray, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. We cover Barnes Cray, about 13 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you. Barnes Cray’s nearest hospital, West Hill Hospital, is about 1 mile south-east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

If you manage shops or offices close to Slade Green station, a TR19® Air inspection shows whether the ductwork needs cleaning. If you run a surgery, dental practice or care home near Barnes Cray, clean ventilation matters as much to you as to a hospital like West Hill Hospital (about 1 mile south-east). Wherever a school like Haberdashers' Aske's Crayford Academy has ducted ventilation, a half-term visit keeps the work out of lesson time.

Keeping the system healthy

Results last longer with the right care. Here’s what we suggest:

  • Book the next check in line with the report
  • Make sure condensate is draining away
  • Report musty smells from the vents right away
  • Report stiff or damaged access doors

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.

Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

What affects the cost of AHU cleaning

We don’t publish a price list, because no two systems are the same. What we look at:

  • How easy every part is to reach
  • The scale of the work
  • Travel, parking and unloading
  • When the work can happen, such as evenings, overnight or weekends

One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.

Helping us quote

To help us quote quickly, please include:

  • Detail shots of panels, filters and grilles
  • The roof, plant room or outside wall the system runs to
  • Photos showing the whole system and its surroundings
  • Any previous report or certificate

Want a quote for AHU cleaning? Please give us a ring on 0345 646 2711, or email photos and tell us about the site. We’ll talk you through the work and send you a fixed quote before anything is booked.

For landlords and multi-site operators

We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
