- Rooms that smell stuffy when the system runs
What affects the quote in Walderslade
You’ll get a fixed price before work begins. It takes into account:
- Travel, parking and unloading
- How easy every part is to reach
- When the work can happen, such as evenings, overnight or weekends
- One-off work versus a regular cycle
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- Any access panels or hatches you can see
We don’t publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, ring 0345 646 2711, or send details by email.
About our AHU cleaning in Walderslade
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. We’re often asked to deal with stale or musty smells from the ventilation and dirty filters cutting the airflow, across dampers and louvres, internal panels and supply and extract fans.
Around a place like Walderslade, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Why act early in Walderslade
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. A planned visit to Walderslade fits your hours; an emergency doesn’t.
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before any work starts.

Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.

Before you book, it helps to know what’s not included:
- Dirty ducts beyond the unit itself

Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 3.2 miles north of Walderslade is Medway Maritime Hospital, the nearest hospital.

The process
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes anything from half a day for one small unit to several shifts for a plant room full of them, and we clear up before we go. Around Walderslade, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
- Move anything stored near the system
Getting a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Advice
Common questions in Walderslade
Do you do school ventilation cleaning in Walderslade in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 12 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Walderslade. You can phone us on 0345 646 2711 or email us with the dates the site is empty.
Is Walderslade within the area you cover?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Can one contract cover all our sites?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
When should our AHU next be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
Common problems we fix in Walderslade
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
The symptoms we’re asked about most are:
- Dust-coated heating and cooling coils
- Plant that needs cleaning after a refit
- Odours coming through the supply air
- Dirty filters cutting the airflow
Hospitals such as Medway Maritime Hospital (about 3.2 miles north) show how much a building can rely on clean ventilation, and smaller healthcare sites near Walderslade are no different.
