Building exterior washing that restores your property's first impression.

Mould, algae, dirt and cobwebs on exterior walls make even well-maintained properties look neglected. We use professional soft washing and pressure washing techniques to safely clean rendered walls, brick, cladding, fascias and gutters across Perth — residential and commercial.

Surfaces we clean

All common exterior wall types.

Different surfaces need different approaches — render requires gentler technique than brick, cladding responds differently to weatherboard. We use the right method for each material.

  • Rendered walls (acrylic, cement, texture coat)
  • Brick and limestone exterior
  • Weatherboard and timber cladding
  • Colorbond and metal cladding panels
  • Fascias, eaves, soffits and gutters (exterior)
  • Retaining walls and boundary fences
  • Commercial building facades
What we remove

The full range of exterior contamination.

Perth's climate — heat, coastal salt air and seasonal rain — creates perfect conditions for biological growth on exterior surfaces. We treat and remove all of it.

  • Black mould and mildew staining
  • Green and grey algae
  • Lichen and biological crust
  • Salt deposits and efflorescence
  • Bird droppings and nesting debris
  • Cobwebs and insect build-up
  • General dirt, dust and pollution
Soft wash vs pressure wash

We choose the right method for your surface.

Not all exterior surfaces can handle the same pressure. Using the wrong technique risks paint lifting, render cracking or joint damage. We assess before we start.

Soft washing

Low-pressure rinsing combined with targeted cleaning solutions — ideal for render, painted surfaces, weatherboard and any surface where high pressure could cause damage. The chemistry does the work, not the water force. Results are thorough and long-lasting.

  • Acrylic render and texture coat
  • Painted brick and masonry
  • Weatherboard and timber
  • Colorbond and metal surfaces

Pressure washing

Higher pressure washing for hard, robust surfaces — effective for unpainted brick, limestone, concrete block and masonry where maximum grime removal is the priority. We combine pre-treatment with pressure for the most difficult contamination.

  • Unpainted face brick
  • Limestone and sandstone
  • Concrete block and masonry
  • Exposed aggregate render
Why it's worth doing

Exterior cleaning isn't cosmetic — it's maintenance.

Prevents long-term damage

Mould and algae retain moisture against your walls, accelerating render breakdown and paint failure. Regular washing extends the life of your exterior finish significantly.

Boosts kerb appeal instantly

A clean exterior transforms how your property looks from the street — ideal before selling, renting, or simply taking pride in your property.

Eco-responsible treatment

Our cleaning solutions are biodegradable and safe for garden beds and landscaping around your property. No harmful runoff left behind.

Commercial-grade equipment

We use professional equipment capable of reaching full two-storey heights safely — no scaffolding required for most standard residential properties.

Ask a question

High pressure is not recommended for most rendered walls — it can crack, lift or erode the render. We use soft washing for render: a low-pressure rinse combined with professional cleaning solution that breaks down mould and grime without risking surface damage.

We use biodegradable cleaning solutions that are safe for garden beds and surrounding landscaping. For particularly sensitive plantings we can pre-water and cover them as an extra precaution.

Yes — our equipment reaches most standard two-storey residential properties without scaffolding. For very tall or unusual structures we'll advise upfront on access requirements.

A standard single-storey residential home typically takes 2–4 hours. Two-storey homes and commercial properties take longer. We'll give you a time estimate when you book.

Most Perth homes benefit from a building wash every 1–2 years. Coastal properties, homes under significant tree cover, and those with north-facing walls (more moisture) tend to need more frequent cleaning.

We clean the exterior of gutters and fascias as part of a building wash. Internal gutter cleaning (clearing leaves and debris from inside the gutter channel) can be arranged — let us know when requesting your quote.
