AHU cleaning for sites in Crowthorne

Different parts, different methods

Internal casing and panels

Dust settles on every internal surface of the unit. We clean each section from intake to discharge.

Rooftop and plant room units

Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.

AHU cleaning in Crowthorne

We clean air handling units for buildings in Crowthorne and across Wokingham, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you are dealing with dirty fans and fan housings and filters that are clogged or overdue, we can help.

In a town like Crowthorne, ventilation cleaning normally means offices, schools, surgeries, care homes and leisure buildings. Their supply and extract ducts all gather dust over time.

Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Fixed quotes for AHU cleaning in Crowthorne

The survey tells us what the work involves. The main factors are:

  • Access, including roofs, risers and ceiling voids
  • Travel, parking and unloading
  • The condition we find in the survey
  • Site requirements such as sign-in and permits

What you pay depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

What we need to know

Photos let us diagnose from a distance. Try to include:

  • Any symptoms, from odd noises to smells or leaks
  • The site address and the type of premises
  • Your opening hours and when the area is out of use
  • Any previous report or certificate

Ventilation in Crowthorne buildings

The FSA’s food hygiene register lists about 8 schools, colleges and universities and about 21 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service within 1.5 miles or so of the middle of Crowthorne. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 0.9 miles north of Crowthorne is Pinewood Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Crowthorne is about 32 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.

School buildings such as Crowthorne Church of England Primary School are normally done in the holidays, so classrooms are not disturbed.

Crowthorne is about 3 miles south-west of Bracknell, in Wokingham. Every kind of commercial site in Crowthorne, AHU cleaning is something we can help with.

Common questions in Crowthorne

Do you work overnight in Crowthorne?

Yes, we can come after you close and finish before you open. Your customers, staff or residents in Crowthorne needn’t be disturbed. Just phone us on 0345 646 2711 or email us with your opening times and we will plan around them.

Is Crowthorne in your area for AHU cleaning?

Yes, we work in Crowthorne and the places around it. To start, ring 0345 646 2711 or send us an email with a few pictures of the system.

What about areas you can’t get to?

They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.

Can you come out in an emergency?

Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.

How long does an AHU clean take?

Expect it to take anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.

Can one contract cover all our sites?

Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.

How much notice do you need?

For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.

What’s included in an AHU clean?

Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.

When to call us in Crowthorne

Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.

Common reasons sites call us are:

  • Debris and leaves in the fresh air intake
  • Units that have only ever had filter changes
  • Fan sections that haven’t been cleaned in years
  • Units needing a clean before a new tenant or handover

Pinewood Hospital, about 0.9 miles north, is the nearest hospital to Crowthorne, and healthcare sites of every size need their supply air kept clean.

Before booking anyone

  • Proof of insurance
  • Exactly which parts of the system are covered
  • Whether VAT is included
  • Whether the price is fixed

Choosing a duct cleaning contractor

What your team can do, and what needs us

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

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, which is where we come in.

Why act early in Crowthorne

Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Whatever the system, dirt and wear only get worse.

No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

Why us?

  • Survey first, then a fixed quote
  • Each visit written up, with photos

What a clean will not put right

Before you book, it helps to know what’s not included:

  • The supply and extract ducts, quoted separately
  • Building management system faults
  • Damaged coils beyond cleaning

Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.

What the work covers

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

What we do, step by step

When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes from a few hours for a compact unit to a day or more for a large one. Three things shape a visit in Crowthorne: when you’re closed, where we can park and how we get to the system.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. We take before photos of each section of the unit.
  3. We work through the unit from the intake to the outlet.
  4. We finish with the fan section and the drain tray.
  5. After photos are taken and the certificate issued.

Preparing for the visit

  • Mention any locked doors, roof access or ceiling voids
  • Let us know when the site is closed or quiet
  • Make sure equipment near the work can be switched off and left to cool

Getting a quote

Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
