What we’re called out for in Pett

Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.

What we’re most often called out for:

  • Drain trays holding standing water
  • Debris and leaves in the fresh air intake
  • Air handling units with blocked filters
  • Air handling units due a clean after building work

In Pett, we look inside the system before deciding what needs cleaning.

Before booking anyone

  • If they look at the system before pricing
  • If the quote is a fixed price or an estimate
  • When they can work, and whether that’s outside your opening hours

Questions to ask before you book

How we handle AHU cleaning in Pett

Our AHU cleaning covers sites in Pett and the rest of East Sussex, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you have filters that are clogged or overdue and plant that has been serviced but not cleaned, we can help.

In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.

It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How it works

We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before we start, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. A few photos of the system help us make the most of a visit to a place like Pett.

  1. We survey the unit from pictures or on site and agree what’s included.
  2. We arrange the shutdown with your staff and sheet the area.
  3. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  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 photos.

Preparing for the visit

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Allow time for equipment near the work to be turned off and cool down
  • Let us know about parking and loading

Common questions in Pett

Do you work at weekends in Pett?

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just ring 0345 646 2711 or send us an email with your opening times and we’ll plan around them.

Do you cover Pett for AHU cleaning?

Yes. We work across London and the South East, and Pett is part of that. You can phone us on 0345 646 2711, or send details by email and tell us what needs doing.

Can we book visits on a schedule?

Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.

Do you look at the system first?

Yes. Photos often do the job, and larger or hidden systems get a visit.

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

Anything we can’t reach goes on the report, with pictures where possible, and we tell you what would make it reachable, for example new access panels.

How do you protect the area?

We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. At the end, the area is cleaned down.

What does AHU cleaning cost?

There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before any work starts.

Do you have insurance?

Yes. Full insurance covers our work and have been trading since 2009.

What staff can safely do

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

What a clean will not put right

We won’t sell you work that doesn’t address the problem, so these are the things it will not cover:

  • Building management system faults
  • Ventilation that was badly designed in the first place
  • Breakdowns that need a mechanical engineer

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

Parts of the system we cover

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

Why it’s worth doing now in Pett

Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. It’s simpler to plan the work at Pett now than to arrange it in a hurry later.

Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, call 0345 646 2711, or send details by email for straight advice and a fixed quote.

Looking after it afterwards

Looking after the system between visits is straightforward, and it makes the next visit easier:

  • File each AHU report in the maintenance log
  • Keep filter changes on time and recorded
  • Do not store bins or materials near the intake
  • Check the drain tray is emptying during routine visits

Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.

Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.

Landlords, agents and facilities managers

We work for landlords, managing agents and facilities managers as well as the people running the site. 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.

If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
