About our AHU cleaning in Cranbrook
Where a building in Cranbrook has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. Common call-outs are for dirty fans and fan housings and debris and leaves in the fresh air intake, on internal panels, heating and cooling coils and filter sections.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Cranbrook is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How it works
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. Loading bays, visitor permits and roof access are the first things we ask about for a site in Cranbrook.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Arrange a key holder or contact on site
- Tell us the best time to work, such as after service or at a weekend

Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.

Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 2.1 miles north-west of Cranbrook is Wanstead Hospital, the nearest hospital.

A few issues sit outside what this work can do:

If in doubt, call us on 0345 646 2711 or send us an email and we will say what we think before booking.
Where we work
- Internal panels
- Drain trays

Part by part
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
What happens if it’s left?
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. For a site in Cranbrook, fitting the work in overnight now is far easier than closing at short notice later.
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.
