As always, there is more than one way to approach a job, and every job varies. In the exterior cleaning industrie, there are often conflicting points of view, which are often both correct in context.

My methods consider all of these factors, including soft washing (chemicals), pressure cleaning (often associated with high pressure), and preparation (looking for potential leaks, identifying substrates, and determining the best practices).

the right active solution is always better than more pressure.

Exterior Cleaning:

• ▸ Drainage
• ▸ Operation of water barriers, Sarking, and seals
• ▸ Visual defects—cracked tiles/windows, the condition of roof zip/screws (seals/washers)
• ▸ protection of electrical components (disconnection of power)
• ▸ Maintained pressure equipment
• ▸ dicersion protection of rainwater and fishponds

"Assuming no formal Quote"

1. Set up safe access and egress as per OHS.
2. Assess materials and condition for the use of appropriate solutions, ratios, and equipment.
3. Communicate the safest and most efficient approach, along with corresponding needs.
4. Proceed with work or set a time and date, booking into the calendar with email or text notifications.
5. Set up any required property and personal protection as per working-at-heights and soft wash/pressure cleaning requirements.
6. Ensure completion of all tasks from pre-checks.
7. Proceed with soft washing and/or power cleaning (often used for its water heating and water flow, not just its high-pressure capacity).

During and Post-Work Checks:

• ▸ Review the function and management of property and personal protection.
• ▸ Restore all property protection, like water tank diversions.
• ▸ Deliver a report of successfully completed jobs and recommendations for future maintenance.

Invoicing is done through Xero Accounting. Payment options include:

• ▸ bank transfer
• ▸ credit card
• ▸ cash
• ▸ cheque.

Payment remittance has a grace period until the end of the day after invoicing.

Typical Adelaide Substrates

The external surfaces of homes in Adelaide are built to withstand a unique climate, from hot, dry summers to cool, wet winters. Understanding the best way to clean these surfaces is key to preserving them. Common substrates include concrete, pavers (such as brick and stone), and timber decking.

Boral Cleaning Recommendations

Boral, a leading Australian building material company, provides specific guidance for their products. For concrete and pavers, they recommend:

• ▸ Pressure Washing: A low-pressure setting and wide fan nozzle should be used to avoid damaging the surface.
• ▸ Chemicals: Avoid harsh chemicals and acids, as they can damage the surface and cause discolouration.
• ▸ Maintenance: Regular sweeping and hosing are recommended to prevent dirt buildup.

Dulux Cleaning Recommendations

Dulux, a well-known Australian paint manufacturer, emphasizes the importance of proper cleaning before applying a new coating. Their recommendations include:

• ▸ Low-Pressure Wash: Use a low-pressure wash to remove dirt and other contaminants from surfaces.
• ▸ Sugar Soap: For persistent dirt, a soft-bristled brush with a warm water and sugar soap solution is recommended.
• ▸ Tannin Stains: For timber with high tannin levels, a tannin-removing cleaner is advised to prevent staining.
