Wall & Kerb Cleaning Dublin

Professional exterior wall soft washing, render cleaning, and concrete kerb restoration.

Safe, High-Quality Render & Wall Cleaning

Is your home covered in ugly red, green, or black stains? These are caused by airborne algae and fungi feeding on your wall's render. We clean rendered, pebble dash, and brick walls safely.

High-pressure washing should never be used on rendered walls (like K-Rend or sand-and-cement plaster). High pressure can chip, crack, or completely strip the plaster off, causing expensive damage. At Platinum Pressure Washing, we specialize in low-pressure soft washing. We apply specialized biocide treatments that gently break down and clean away stains, leaving render undamaged.

Our Wall Cleaning Process

We use a safe and durable soft wash process to restore your walls:

  • 1. Surface Analysis: We inspect the type of render or brickwork to select the correct biocide concentration.
  • 2. Biocide Treatment Application: We apply the biodegradable cleaner at low pressure to kill algae, moss, and lichens at their roots.
  • 3. Gentle Rinse: After allowing the treatment to work, we rinse the walls using low-pressure wide fan sprays.
  • 4. Residual Protection: The sanitizing agents leave a microscopic barrier that prevents algae from returning for up to 2-3 years.

Kerb & Boundary Wall Cleaning

In addition to home exterior walls, we deep clean concrete boundary walls and driveway kerbstones. Kerbs get heavy black staining and moss growth due to soil runoffs. We use commercial surface cleaners to restore concrete kerbs to a clean, bright appearance, neatly defining your driveway edges.

Frequently Asked Questions

Common questions about render wall cleaning and soft washing.

Will power washing damage my rendered walls?

Yes, standard high-pressure power washing can strip plaster and cause structural cracks. That is why we use low-pressure soft washing, applying biocide washes that dissolve stains safely without any abrasive pressure.

What causes red and black stains on plaster render?

These stains are caused by biological growth. Red staining is a specific type of micro-algae (Trentepohlia) that thrives in wet climates like Ireland, while black staining is typically a combination of mold and lichens.

How long do wall soft washing results last?

Because soft washing kills biological spores down to the roots, results typically last between 2 to 4 years before algae begins to return, depending on tree cover and moisture exposure.

Do you clean pebble dash walls?

Yes. Pebble dash is very rough and collects dirt easily. High pressure will blow off the small stones, but our soft wash treatment penetrates the gaps between pebbles, dissolving algae while keeping stones intact.
