Your questions about AHU cleaning in Stonebridge

Is parking a problem for work in Stonebridge?

A loading bay, a visitor permit or off-street space near the site in Stonebridge makes the visit easier to plan. Much of our London work is done overnight, which helps.

Can a school’s ventilation in Stonebridge be done out of term time?

Yes. Half-terms and the summer break are the natural time for school work. Around Stonebridge, the Food Standards Agency lists about 37 schools and colleges with registered kitchens within a mile and a half or so. You can give us a ring on 0345 646 2711, or email photos with the dates the site is empty.

Can you set up regular visits?

Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.

What do you do to protect the area?

Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.

How long will the unit be out of action?

Typically the clean takes a single shift for a typical unit, longer for large or heavily soiled ones. We plan the shutdown around that, out of hours if needed.

Which kinds of sites do you work on?

Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.

What should I send you?

Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then ring 0345 646 2711, or email photos.

Do you need to switch the unit off?

Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.

AHU cleaning for kitchens and businesses in Stonebridge

Where a building in Stonebridge has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. Typical jobs include plant that needs cleaning after a refit and blocked condensate drains and slimy trays, on supply and extract fans, internal panels and dampers and louvres.

In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Stonebridge is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.

Accreditations are easy to claim and worth checking. 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 we price AHU cleaning

The diagnosis comes before the price. We look at:

  • How many systems or sites are involved
  • Working hours and out-of-hours timing
  • Site rules, permits and inductions
  • The scale of the work

You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.

Asking for a quote

What to send for a quote:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Close-ups of filters, grilles, hatches or access panels
  • Where the site is and what kind of site it is
  • Your opening hours and when the area is out of use

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Common problems we fix in Stonebridge

Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.

The symptoms we’re asked about most include:

  • Stale or musty smells from the ventilation
  • Drain trays holding standing water
  • Coils clogged with dust and debris
  • Units that have only ever had filter changes

School buildings such as The Stonebridge School are usually done in the holidays, so classrooms aren’t disturbed.

  • What hours they’ll be on site
  • How areas they cannot reach will be recorded

How to choose an extract cleaning contractor

Leave it or put it right?

Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. In a London building, a problem in a duct, damper or fan rarely stays in one unit.

Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call us on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.

For landlords and multi-site operators

If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.

Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.

What staff can safely do

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.

What happens on the day

Before we leave, we walk the area with whoever is on site. 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 one overnight shift for many single units, with bigger plant phased. If your building in Stonebridge has sign-in rules, permits or key holders, mention them when you book.

  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, coils, fan section and casing are cleaned in turn.
  4. Drain trays are cleared and cleaned and the outlet checked.
  5. You get a TR19® certificate and a photo report.

Getting ready for the visit

  • Let us know about permits to work or site inductions
  • Let us know when the site is closed or quiet
  • Clear loose items from the work area

Ask for a quote

Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before work begins.

Aftercare tips

Once we’ve finished, these simple steps help:

  • Look at the condensate drain whenever the unit is serviced
  • Clear leaves and litter away from the intake
  • Flag stale or damp smells in the supply air
  • Make sure the unit’s access doors open easily

Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.

Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
