Low-Pressure Exterior Wall & Render Cleaning Across County Kildare
Eliminate unsightly red algae and dark mould without damaging your exterior walls. In Ireland’s damp climate, rendered walls, K-Rend, Weber plaster, and pebble dash are prone to aggressive airborne organic growth. Bright red streaks (Trentepohlia algae) and heavy black mould spots don't just compromise your home’s appearance—they penetrate porous wall finishes, holding moisture against the envelope of your property.
At PD Power Washing, Patrick Doherty provides gentle, highly effective softwashing across County Kildare. Backed by over 10 years of hands-on trade experience, Patrick neutralizes organic growth at the root level using low-pressure chemical treatments, restoring your exterior walls to pristine condition without the destructive force of traditional power washing.
Exterior chemical washing requires careful environmental management. Patrick guarantees complete site protection on every job:
All garden vegetation is pre-rinsed and post-rinsed with clean water.
Windows, window frames, and glass doors oversprayed during the process are hosed clean.
Runoff is carefully controlled and managed on site.
Why High Pressure Can Destroy K-Rend & Modern Plaster
Blasting coloured render, Weber plaster, or pebble dash with high-pressure power washers is a recipe for expensive property damage. High-pressure water strips away the protective outer topcoat, blows holes in delicate render, forces water past internal insulation barriers, and leaves unsightly wand streaks across your walls.
Softwashing relies on chemistry rather than raw water force:
Frequently Asked Questions About Soft Washing
Power washing uses high-pressure water to physically blast away dirt, which can easily ruin delicate render or plaster. Softwashing uses gentle, low-pressure water combined with specialized biocide chemical treatments that soak into wall pores to sanitize and kill algae spores at the root without physical force.
No. Softwashing is the exact method recommended by K-Rend and Weber plaster manufacturers. Because no high pressure is applied, it safely restores original render color without chipping or stripping surface aggregate.
Because biocide treatments sterilize microscopic spores inside porous render, softwashed walls typically remain clean and free of red algae for 2 to 3 years in the Irish climate—far outlasting standard pressure washing.
Yes. We pre-soak surrounding lawns, flowerbeds, and shrubs with fresh water before and during treatment to protect plant roots. Once the biocide solution dries on the wall, it is completely safe for pets and children.
Red streaks are caused by Trentepohlia, a species of airborne algae that thrives on damp, north-facing rendered walls in Ireland. Softwashing neutralizes this specific algae strain, dissolving the red pigmentation completely.
In most cases, no. Red and green algae stains look like peeling or discolored paint, but a softwash treatment usually lifts the organic growth entirely, revealing clean paint or render underneath and saving you thousands on painting costs.

Our Step-by-Step Softwashing Process
Patrick follows a strict protocol to guarantee maximum stain removal while safeguarding your surrounding landscaping:
Pre-Rinsing & Landscaping Protection: Surrounding lawns, flowerbeds, hedges, and garden plants are thoroughly soaked with clean water before any chemical application. This prevents plant roots from absorbing runoff.
Targeted Biocide Softwash Application: The specialized biocide solution is evenly sprayed across wall surfaces using low-pressure equipment.
Controlled Dwell Time: The solution sits on the surface to break down algae cell walls, lifting red, green, and black organic growth.
Low-Pressure Pure Water Rinse: Walls are gently rinsed clean to remove residual grime and dead spores.
Final Property Washdown: Nearby glass windows, doors, side gates, and outdoor furniture are washed down to ensure a spotless finish.
