Algae Removal & Exterior Cleaning – Restore Your Surfaces Safely

Bring your property back to life with Lowen Cleaning’s specialist Algae Removal service. Over time, algae, moss, and lichen can build up on walls, roofs, patios, and paths — leaving surfaces slippery, discoloured, and potentially damaged. Our expert team uses soft-wash technology to remove organic growth gently yet effectively, restoring your property’s appearance and preventing regrowth.
