About our AHU cleaning in Lamarsh
We clean air handling units for buildings in Lamarsh and across Essex, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers internal panels, supply and extract fans and heating and cooling coils, and common reasons people get in touch are filters that are clogged or overdue and blocked condensate drains and slimy trays.
Somewhere as small as Lamarsh, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- Working hours and out-of-hours timing
- How big the system is
- What state the system is in
- Site rules, permits and inductions
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, call us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
What we need to know
We can often survey from pictures. Try to include:
- How we’d reach plant on a roof or in a plant room
- Wide pictures of the system and the area around it
- Any previous report or certificate
- Any symptoms, from odd noises to smells or leaks

Ventilation in Lamarsh buildings
Lamarsh, about 49 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours. For Lamarsh, the closest hospital is Halstead Hospital, roughly 5.5 miles south-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
An inspection comes first for any ventilation job around Lamarsh, so the cleaning matches what’s there.

What the work involves, part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
Signs you need AHU cleaning in Lamarsh
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 slime and smells soon follow.
It’s time to book a visit if you see:
- Units that have only ever had filter changes
- Air handling units with blocked filters
- Debris and leaves in the fresh air intake
- Dust-coated heating and cooling coils
Hospitals such as Halstead Hospital (about 5.5 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Lamarsh are no different.

Lamarsh: your questions answered
Can you get to a site in Lamarsh?
Yes, Lamarsh is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Can you come to Lamarsh after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Lamarsh keeps running as normal. When you call us on 0345 646 2711 or send us an email, mention when the site is quiet.
Do you have insurance?
Yes. We are fully insured, and the details are available on request.
How much notice should we give?
The more notice, the better, especially for out-of-hours work. We normally quote within one working day, and there’s a 24/7 line for emergencies.
How much does AHU cleaning cost in Lamarsh?
It depends on the site, so we quote each one individually. To get one, give us a ring on 0345 646 2711 or use the quote form and tell us about the site and its opening hours.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
Is there a report after cleaning?
Yes, both a certificate and a report with pictures. It includes a recommended date for the next check.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.

Managing agents and facilities teams in Lamarsh
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
What we do, step by step
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. On site, it takes anything from half a day for one small unit to several shifts for a plant room full of them. The timing of a visit to Lamarsh is set by you, and the travel is our side of the planning.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
How to prepare
- Let us know about permits to work or site inductions
- Let us know about parking and loading
- Tell us the best time to work, such as after service or at a weekend

Leave it or put it right?
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Planning a trip to Lamarsh ahead is easier for everyone than a rushed one.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
