Pressure Cleaning Your House in Sydney? What You MUST Know Before You Spray

Many Sydney homeowners think “pressure cleaning house” when they want to remove dirt, mould, or grime from their home’s exterior. It sounds like a quick and powerful fix. However, using high-pressure water directly on many parts of your house can cause significant, costly damage. At EdgeFlow, we believe in educating our Sydney clients about the safest and most effective cleaning methods. Before you consider “pressure cleaning house” surfaces, understand the risks and the professional alternatives.

What Does “Pressure Cleaning House” Usually Mean (and Why It Can Be Risky)?

Often, when people say “pressure cleaning house,” they envision blasting away dirt with a powerful jet of water. While high pressure has its place for certain robust surfaces, applying it incorrectly to a house exterior is dangerous. The term is often used loosely, but it’s crucial to differentiate between:

• High Pressure Cleaning: Uses very high PSI water force. Suitable only for very durable materials.
• Pressure Washing (General): Can involve varying pressures, sometimes moderate.
• Soft Washing: Uses low pressure (like a garden hose) combined with specialized cleaning solutions. This is the preferred method for most house exteriors.

Assuming high pressure is safe for your entire house exterior is a common and potentially damaging mistake.

Where *Could* Pressure Cleaning Be Safely Used on a Sydney House Exterior? (With Extreme Caution & Expertise)

True high or even moderate pressure cleaning should only be considered by professionals on very specific parts of a house exterior, such as:

• Highly Durable, Unpainted Brickwork: Even then, care must be taken not to damage mortar joints. Professional assessment is needed.
• Solid Concrete Foundation Walls or Plinths: These can often withstand pressure better than siding materials.
• Adjacent Hardscapes: Connected concrete driveways or pathways might be suitable candidates for standard pressure cleaning services.

Crucially, these applications still require careful technique and the correct cleaning pressure selection by a trained professional.

CRITICAL WARNING: Where NOT to Use High Pressure Cleaning on Your House!

Applying high pressure cleaning to these common house exterior elements is highly likely to cause damage:

• All Types of Siding: Including Vinyl, Weatherboard (Timber or Composite), Fibre Cement Sheeting, Render/Stucco, and any Painted Surfaces. High pressure can force water behind siding leading to mould and rot, crack render, strip paint, gouge wood, and cause irreversible damage.
• Windows and Doors: High pressure can break glass, damage seals leading to fogging between panes, damage frames, and force water indoors.
• Roofing Materials: Cleaning roofs requires specialized low-pressure techniques. High pressure will dislodge tiles or shingles, damage protective coatings on metal roofs like Colorbond®, and cause leaks. See our roof cleaning information.
• Soffits, Eaves, and Fascias: These are often made of softer wood or thinner materials and are easily damaged. Water forced into eaves can enter the roof cavity.
• Vents, Seals, and Caulking: Easily damaged or dislodged by direct high pressure spray.

Attempting “pressure cleaning house” surfaces like these can quickly turn into an expensive repair job.

The Safer, Recommended Method: Soft Washing Your House Exterior

For the vast majority of house surfaces, the professional standard is **Soft Washing**. This technique involves:

• Applying specialized, biodegradable cleaning solutions at very low pressure (similar to a garden hose).
• These solutions work to kill mould, mildew, algae, and other organic growth at the root, while also loosening dirt and grime.
• Allowing the solution adequate dwell time to work effectively.
• Thoroughly rinsing the surfaces with clean water at low pressure.

Soft washing is safe for virtually all types of siding, paintwork, windows, and other delicate house exterior elements. It delivers a deep, lasting clean without the risk of damage associated with high pressure. This is the primary method used in EdgeFlow’s professional house washing service.
